Everything Changes and Always Has

Our family has farmed here in North East Essex since the 1880s. In those early days the focus was on sheep, with my great grandfather developing a flock of pedigree Suffolks to graze the extensive marshes that made up most of the farm. The flock was dispersed in 1926 as part of farm re-organisation. A herd of dairy short-horns provided a milking herd at Walton hall farm through the 1940s and 50s, which my parents then evolved into freisian cattle herd. This herd moved to Devereux farm in the mid-1960s, which is where is was when I joined the farm in 1982. Sadly, as with the sheep, the dairy herd was finally sold in 2002 leaving the farm without livestock.

From 2002 the farmland has developed in two directions. Half has been devoted to growing crops of wheat, barley, peas, beans, rape and tares. The rest has been set aside to provide habitat for the wildlife associated with the neighbouring Hamford Water National Nature reserve. Habitat does not just happen, it evolves and nature evolves with it. The term biodiversity is banded about often, but a broad stable biodiversity only happens given an existing viable ecosystem being given time to expand. Our farm has had some traumatic events, such as the 1953 flood.

An uncontrolled flood drowns everything in its path. It contaminates the soil and if not dispersed back to sea, sea water is toxic to terrestrial plant life. Following the 1953 flood the sea walls were rebuilt both by digging clay from the fields closest to the walls, but also by bulldozing the topsoil from them. Before the flood many of these marshes were un-improved grazing marshes with a mix of plant species and microfauna that had been there for possibly centuries. This would of course have sustained a vibrant biodiversity. Many locals lived off plentiful stocks of fish and huge flocks of wildfowl. After 1953 all this changed. The farmland was first planted with grass and took ten years to come back into use. But the traditional grazing marshes had gone and this presented the opportunity to grow arable crops – at a time when both the UK and Europe were still recovering from the war. The early cereal crops would have yielded 2 tons an acre, which rose to 3 tons by the 1980s. But this transition from extensive grazing marsh and and its natural habitat degraded the ability of many species to remain viable in the area. This is not to say that cereal growing on the marshes removed all habitat area. Hedges remained. Wide creeks and ponds provided freshwater areas for breeding waders. Skylarks, grey plover, grey partridge could still be found, but diminishing habitat will also have an impact.

The moral of this story is that farms are not static businesses, they evolve. Over ten years ago the farm started to change again reducing its cereal growing land and returning it to become habitat. The advent of EU based agri-environmental schemes provided a choice of approaches but for our farm developing larger areas of habitat rather than just providing margins around fields seemed the right approach.

One radical project included breaching one of our sea walls to create an intertidal habitat extending a 50 acre area of mature salt marsh within Hamford Water onto our farmland. Crucially it will reduce the impact of a repeat of the 1953 flood as the sea can now flow through the breach in the sea wall and spread out across the land at Devereux farm. It has been a great success and what was once farmland has developed a biodiverse salt marsh.

Why is all this important?

This blog has been focused on the sea buckthorn crop that is developing at Devereux farm. The sea buckthorn project could not have developed if the rest of the farm was not able to support it. In time it will be the sea buckthorn which as a new enterprise will support other new projects that will drive the future viability of the farm. But what drives all of this is the appreciation of how special the working environment of a farm actually is. It grows on you and you become it. The fact it is possible to make a living from this environment is important, but it is valuing the environment as a key resource that makes the business and that will make it sustainable in the future.

This year the lack of rain will impact on all our harvest – both the sea buckthorn and the arable crops. Next year that position will hopefully be better, but if we are really seeing climate change driving different weather patterns then we will have to adapt to meet the challenge.

To a large extent though this farm has never stood still and has for over 100 years been continually changing and adapting – so whatever the weather – and maybe whatever the politics of the time, we will just carry on moving with the times.

Weather a Factor of Now and for the Future

April used to be the month for showers there has now been 42 days without any rain. The sea buckthorn field at Devereux farm has had 101 mm of rain since January 1st, this being almost 50% of last year’s total and 40% less of the average over 33 years since 1984.

What does all that mean? The sea buckthorn looks well but there are some odd plants under stress with leaves dessicated and potentially looking as if they might die. This will not be due to lack of rain but more likely these plants are in areas where the soil is predominantly  rank clay. This would put the plants under stress and allow disease to get the upper hand.

I still believe that the compost tea application has a beneficial effect under these conditions. To test the case the Siberian plants will be split up so some will have an application every month, some every six weeks, and some every two months.  This is not necessarily a scientific study but with the plants under stress it will be an indication as to which areas have more/less plants with disease or other stress symptoms.

One of the issues with farming is that every year is different as this season’s weather conditions are indicating. With sea buckthorn there is the added issue that there are no guidelines as to how to manage the crop here in the UK. As the crop is also being grown organically the options are limited. In past year’s the overall weed population has been allowed to grow both between the rows and in-between the plants. This has become a real problem, particularly for weeds like creeping thistle which has spread across the site to such a degree that this year a zero tolerance approach has started. Mowing between the rows every two weeks to a very tight sward height together with striming between the plants.

Striming up until now has been with a Stihl petrol backpack strimer. A great tool, but in the long term reducing the carbon footprint of producing the crop is important. I believe that within 10 years carbon foot-printing will appear on food labels. Apart from that it is only right that we should make every effort to reduce use of fossil fuels – and every small bit counts. So this month a Stihl electric strimer arrived. Its battery is still a real constrain as one battery charge allows striming of about 75 plants only. It then takes 2 hours to recharge. All this means is starting every day with striming, then planning the day so that other jobs fit in-between up to four striming sessions a day. Technology still has a way to go before battery power becomes a fully convenient option, but for now the opportunity of not having to be reliant on the petrol station feels good.

Standards are part of what develops quality. Quality is often a subjective issue and it is made up of many factors. Choosing to be organic fits with the desire not to be using chemicals, which may impact on soil health and product quality. Proving these issues is difficult, but there is certainty in as much as – if you don’t use chemicals, you can be certain that neither soil nor product will have any form of contaminant. Interestingly as Brexit gathers pace, last week, on April 19th the EU established a new electronic tracking system for all imports into the EU of organic products. This aims to further ensure that organic means organic and that food products can be traced back to the grower. Memories of the horse meat scandal in Europe is just one area where fraudulent product labelling tried to pass off substitute product onto consumers.  It is in the best interests of both growers and consumers that there is confidence in standards and this EU system sounds like a positive move to further close loopholes.

Carbon foot-printing has been discussed in terms of food miles, but this is often confusing as sometimes low energy production methods in warm climates can be beneficial against UK production  even with the inclusion of air transport. We have become so used to exotic foods becoming the norm and there being no reliance on seasonal foods that understanding what food miles are acceptable and what are not is difficult to assess. That said the individual producer can influence production methods to reduce energy reliance and use. This is fine but it is only when this is benchmarked against other products that the efforts of the individual can be assessed objectively by the market and the consumer. Carbon foot-printing is just one other standard awaiting acceptance in the marketplace. If climate change is going to be managed then these standards might be one means of ensuring that food production is accountable and able to identify the means to limit its impacts upon the global environment.

As the president of the US has remarked that climate change is a hoax one needs to consider the evidence. As a farmer the weather that we are growing used to is no longer consistent with seasons. As a coastal farmer the seas are becoming more threatening with flood risk from surge tides now becoming a five yearly occurence rather than a once in a lifetime event. The problem with ignoring these issues is that time is not on our side and it is a supremely selfish attitude to think that the problem will not be an issue in our lifetime.

All one can do is do your individual best and hope that collectively enough effort is made that our children and theirs will not have to suffer the consequences of our lack of taking responsibility for these issues.

Gentle Technology

Devereux farm is in North Essex. An area that has attracted tourists for decades, so much so that it has become known as the “Sunshine Coast”. This name is becoming very apt this year as day after day of sunshine fills our skies. This is good for tourism, but it is starting to become a concern for farmers, growers and gardeners and already there is talk on the radio of hose pipe bans.

We are of course getting used to each year becoming a record year for some form of weather event – the wettest, the driest, the hottest and so on. The discussion as to whether this is climate change driven is not the point. The fact is that we are experiencing weather that is not typical of the last century. President Trump may want to put across his view that climate change is a hoax, but the fact is that the weather we have is noticeably having an impact on our lives.

The Devereux farm sea buckthorn is looking well as it enjoys hot weather and does not like too much rain. The first compost tea application last month has started the monthly cycle that provides both a foliar leaf feed and includes natural microbes that control fungal diseases. This simple organic management is delivering results.

Whereas up until now each year I have allowed a level of weed growth inbetween the plants and between the rows, I am changing this to cutting regularly. This reason for leaving the weeds had been to reduce the amount of mowing/strimming/hand weeding but also in the belief that these weeds harboured beneficial insects that predated on pests like aphids. Unfortunately the result has become an infestation of creeping thistle. The long dry winter has allowed a total weeding process to bring this problem under control. It might well be that once the thistle has died out then I can sow a seed mix which can provide attraction for beneficial insect habitat. But nothing will establish against the rampant spread of thistle.

Mowing and strimming is all very well, but I am concerned as to limiting the amount of fuel I have to use. This principally from an environmental perspective. So this morning i have taken delivery of a battery powered Stihl strimmer. The battery only carries enough charge for 45 minutes of strimming, but this will allow for a daily sweep along the rows and between the plants to trim down thistles as soon as they start to emerge. It would be good to find a mower that is electric, but battery technology still needs to improve to allow for the amount of mowing that needs to be done on the site.

The other form of technology that has arrived this month is a Bio-Acoustic bird scaring system. For the past two years jackdaws and magpies have been attracted to the sea buckthorn to eat the berries. They have particularly targeted the Siberian varieties which have a natural sugar content higher than the German varieties. Scaring rockets, kites, scare crows, flashing tapes have had no impact on the birds’ desire for the fruit. The problem starts once the berries are ripe – so in June through to July and August. At this time of year the birds make use of early sunrise and late sunset. Their activity was caught on a wildlife camera showing how even a large bird can rest on what look like flimsy branches and strip berries with ease.

One of the options would have been to shoot the birds, but this is neither ethically right nor really practical. So netting the plantation is the next best option, but these birds are intelligent and it might still be possible for them to find a way in, then creating the problem of getting them out. The technology option has been around for sometime but equipment has improved. I have chosen the “ScareCrow B.I.R.D system” marketed by Martin Lishman, who also supply the compost tea brewing system I am using. The equipment has three speakers which emit distress calls that different bird species recognise as indicating there is danger in an area. The system has ten different specie calls programmed into it that can be selected to scare specific birds that pose a problem. In theory it has a range of 300 metres which will cover no only the sea buckthorn field site but also the fields adjacent to it. The most mature block of Siberian plants will still be netted, but hopefully the BIRD system will keep the jackdaws away allowing for a successful harvest this year.

A successful harvest of fresh berries will be a first for the UK, but of course sea buckthorn products are available on the internet. These products are marketed as providing a range of benefits, but there is nothing  like fresh fruit itself. A research paper released from University of Exeter recently helps to re-enforce this. The work is based on the consumption of fresh fruit particularly by elderly adults and the impact on improving cognitive performance. The fruit used was blueberry, pomegranate and orange, but all these referred to  the polyphenol content in these fruits – which sea buckthorn is partricularly rich in. Polyphenols come in many forms in different fruits. Flavonones in oranges, flavonoids in blueberries, elligitannins in pomegranate are three individuals named within these fruits, but in effect each fruit has a multiple complex of other polyphenols which provide the health benefits that we all associate with eating fresh fruit and vegetables. It is that fresh issue that makes a difference. Other research work just released from the University of California, Keck school of Medicine illustrates how high potassium levels in some vegetables and fruits can be beneficial for reducing blood pressure. Interestingly this is another characteristic attributed to taking sea buckthorn oil capsules, although not specifically relating to potassium levels in the oil.

All of this relates to how natural foods tend to offer greater benefits, but then it is technology that can provide solutions to how we can minimise our impact on nature.

Change, change, change.

Devereux farm is on the coast. Being less than two hours from London, this part of the Essex Coast has attracted people for decades to its beaches, mild weather and sunshine. Many of those visitors become so attracted to it that they come to live here. Such an attraction is based on memories of good holidays and as with all of us, those memories are so good that when areas develop we do not like to see them change. But change is inevitable and constant.

It was with interest therefore that I noted a familiar topic on change when reading the March edition of the Fruit Grower magazine. At the recent British Independent fruit growers Association (BIFGA)technical conference, Christopher Atkinson, Professor of Sustainable Agriculture at the University of Greenwich quantified a specific impact of climate change that I have not heard of before – but that which is very relevant to my growing of Siberian sea buckthorn.

He presented data that indicated evidence that winter chill is changing. The figures related to Kent top fruit growers: in years 1969 to 1979 the mean chill total was 2545 hours compared to 2235 hours from 1987 to 1997. The relevance being that every perennial fruit crop must have a certain number of chill units to break dormancy. To break dormancy they need to be warmed, but if the rate of chilling is upset then bud-break happens at an abnormal time then it upsets the timing of pollination and potential future yield. He proposes that these changes are down to a changing climate. On the basis that 16 of the 17 warmest years have been recorded since the millenium, I will be writing to Professor Atkinson to ask whether he has reviewed what the chill figures are for the last ten years in comparison with 1987 to 1997.

This sounds very familar with what is happening at Devereux farm. Siberian variety Klaudia has become the odd ball of the ten Russian varieties on site. Last year breaking bud on New Year’s eve, this year on January 20th, with all varieties breaking bud by February 17th. This is of course perverse in Siberian terms where the winter will keep the plants frozen well into April. The impact though comes when considering pollination. Sea buckthorn is wind pollinated so males have to open their flowers and distribute pollen to receptive female flowers.This process happens with swelling of flower buds taking a week, approximately two weeks ahead of mass flowering. Full blown flowering happening over a seven day period. For all this to happen the female and male flowers need to open at the same time, with a little variation for variety. But my experience here in the UK is showing that Klaudia is coming so early that it is outside this pollination window. It seems that Sudarushka has the same problem but at the other end of the spectrum – coming too late. This will impact upon yield and potentially these two varieties may not produce berries. It will be interesting to see.

It is for these sort of reasons that this week we installed the first trial electronic tags onto 48 plants as a start of using the Sectormentor data recording system ( www.tech.vidacycle.com). These tags provide auto identification to an iphone, to allow for easy recording of data on particular plants. The system will allow recording of all aspects of plant development, disease, pest incidence and yield attributes building up specific data  over a period of time allowing us to adapt management technique to improve the crop as years go by.

But changes in climate are not new, neither are the ways that plants adapt and evolve to these changes. Back in January a presentation at the Naze, Essex Wildlife Trust new centre introduced a project in Suffolk at a site where there is a geological exposure of 4 million year old Coralline Crag. This strata being made up of layers of crushed sea shells being compacted at a time when the area was approximately 30m under the sea.

Back in the 1960s Professor Richard West took a core sample through this strata and on analysis discovered fossilised pollen from plants living 4 million years ago. This pollen having been blown from adjacent terrestrial landscapes, then to sink into the strata to become fossilised. These were identified indicating the type of landscape that one might have found so long ago. The research indicated specific plant family or genus, but clearly could not be specific on species.

This work inspired a fascinating project created by members of the GeoSuffolk group. Taking the plant data they have matched it against plants living today of the same genus and planted examples of them into the site. This has been done in a controlled way with the permission of Natural England, and offers an indication of the visual concept of trees that made up the forest and landscape of the area so long ago.

This landscape disappeared with the arrival of glaciation and it is a reminder that over millions of years the climate has been changing continually, although gradually. Our current form of climate change may be contentious as its rate of change is more of an issue.

As a grower of a crop transported from its native Siberia to the mild Essex coast, I have forced climate change onto my plants. The project in Suffolk indicates that plants do adapt and evolve as the same plant families exist now as they did 4 million years ago. It will be interesting to see how my sea buckthorn adapts to its changed environment.

As Professor Atkinson added in his presentation at BIFGA, the problem with climate change is that it is not simple nor consistent, so trying to plan to manage change is not easy. Change may be constant, but there are many variables that make it unpredicatable, but that is what makes the challenge of growing a new crop like sea buckthorn exciting.

Technology and people power solutions

February is here and finally pruning 3000  Siberian plants was finished. Removing dead twig; low branches; and bringing plants down to a manageable height has resulted in a mountain of prunings. Each variety showed its character. Klaudia demanded more pruning as its habit to grow squat and sprawling makes mowing difficult without damaging low branches. The opposite is Inya, growing tall and straight without bushiness. Then Chuiskaya, whose size now bulks out ahead of all others. Elizaveta, whose fast growing habits in our different climate resulted in branch die back leaving plants tall but thin. Time to experiment and practice has resulted in developing management techniques so each of these varieties are adapting to our climate and soils. All of these developments come from simple observations of the characteristics of each variety. Observation is important but recording this monitoring so information can be used to develop management systems is another.

One of the presentations at the Oxford Real farming conference was by a vine grower, using a plant monitor system – sectormentor. Giving selected plants an electronic tag and using an old iphone to record plant condition traits provided a simple system that looked ideal for my sea buckthorn. This will build up a concept of which varieties are performing best and where problems need to be managed. It will remove the problem of observations being subjective and kept in a record system which is easy to analyse.

February is still cold with temperatures fluctuating from freezing to up to 8 deg C. Our old friend Klaudia has again been the first to show some leaves. Over a month later than last year Klaudia buds are breaking open across the field. It has started the process of planning the first application of compost tea. It needs a good showing of young leaf to make it worthwhile. Last year, the males plants that are essential for pollination, came into the spring in really poor condition. Poor pollination resulted in few berries, something I had to address for 2017. With pollination starting in April, being able to boost the plants to optimum health is essential. Once enough leaf is present across the field then first compost tea feed will be applied and each month until before harvest.

With thoughts of pollination, come thoughts about harvest – and how to solve the problem of birds. The old traditional method would have been to shoot them. Last year I bought a netting system which will cover two blocks of the plants. But hungry birds still find a way in under the netting. I have now tried kites, rockets, scare crops, flashing tapes, CDs on strings – all to no avail.

Technology is changing our lives daily and it is to technology that i have turned for a solution for birds eating my precious sea buckthorn berries.

The manufacturer of my compost tea brewer, Martin Lishman and developed an electronic bird scarer. It can be programmed to scare different bird species and provides cover for an area of around 300m. This farm scale tool has three directional speakers that emit warning sounds to pest birds to make them believe they are being threatened by a predator. A large investment, but a practical more ethical solution to keep the birds off the sea buckthorn crop . A tool that along with the timing of the  compost tea provides confidence for a good 2017 berry harvest.

Confidence is essential, but the future is never certain. On Tuesday I went to a Climate change meeting at Westminster Hall, London. When I go to these events I have to ask myself why. Is it simple interest or will something real come out of it? With Brexit and Trump creating uncertainty, focus on climate change may slip down the political agenda. The elections in EU States in 2017 add to the uncertainty. Understanding where these arguments are going has a material impact on the farm.

The farm has 5 kilometres of sea wall protecting it from sea flooding. The walls, rebuilt after the 1953 flood, have seen two serious surge tides recently – 2013 and January 2017. Whether it is global warming or climate change means little. What is important is unpredictable events are becoming more frequent. The surge tides threaten the very existence of my family’s farm. The impact of our emissions into the atmosphere has been tracked by science for decades. Every year since the millenium year we have had major flood events in the UK. Something is changing and it’s not for the better. The farm is at risk from this change and maybe politicians are key to regulating our lives to slow the process.

I came away from Westminster with some confidence – but not from hearing about political decision making. The message was that major international businesses are changing their operations to reduce environmental impact. This is not driven by regulation but by their customers demanding change and the fear they might buy from some one else – real people power. The second message was that clean technology in  energy, transport construction, and appliances is becoming a reality. Third, whereas mature economies have to change their old technologies, new growing economies will invest directly into efficient energy systems. Economics not politics is finally driving change – and I for one felt more confident that our world has a chance to manage the climate on which we rely to live.

 

having heard all four speakers at the event more buoyant than I expected. Business opportunity from green issues and new, non carbon based technology was moving ahead fast and seen soon to become a reality. It was also interesting to hear that Africa was in a strong position as having the potential to adopt new clean technology without having invested deeply in old carbon based alternatives  . What will happen in China we will have to see but their commitment in Paris made a powerful statement.

Our UK farming industry is seriously turning to putting soil health at the heart of its workings. An industry that has been a target of criticism for not caring for the environment painted a broad picture ignoring the many, many farmers who feel they are custodians of their land.

A chill New Year warmed by global research.

Some things are predictable, some are less so. Since Christmas, the weather at Devereux farm  has been characterised by regular nightly frosts – up to -5 deg C. This is a 100% reversal of our night weather in 2015/16. Then, following a sustained incredibly mild period the buds on the Devereux farm sea buckthorn plants started to spring to life on December 31st. The reversal to winter weather this year has had an impact on this particular Siberian variety (Klaudia), which possibly should be predictable. The first terminal buds on Klaudia emerged on January 20th 2017.

How this will effect the plants and their potential harvest we will have to wait and see, but each of our 10 different Siberian varieties are developing differently.

The current task is to complete pruning. This is a time consuming job. It can also be disheartening. Our field trials are indicating the importance of soil type. The trials were planted in four blocks – each with different planting parameters. The “A” rows, planted in 2012, cross over ground that used to grow a good crop of wild oat weeds when the field was used purely for arable cropping. This area specifically is proving to be a problem for the sea buckthorn. Rows A11-A15 have had considerable plant losses. This week I have had to cut out six plants in rows A14/A15 that are now maturing to large plants, but have died. After four years this is really frustrating. Even more so as there is little chance of finding out why the plants have died. These are individuals where adjacent plants are fit and healthy. I suspect it is a soil based problem. On Tuesday Ben and I are going to a day course on soil. This will present a chance to take a sample of the soil from around these dead plants and see if it is possible to identify a reason for losing these plants so dramatically.

Developing a depth of knowledge is what science is all about. I do not believe there is such a thing as constant fact, as new research keeps improving on understanding more about the world we live in. This week was highlighted by the publication of a piece of research in the journal “Trends in Food Science and Technology” published by Elsevier on the net.

Sea buckthorn as a natural berry has been accepted in traditional medicines as providing health benefits for centuries across northern Europe and Asia. Every year there are research papers published, but for these works to be accepted in European science journals they have to be of a high, peer reviewed standard. For health benefit research to be accepted as credible it needs to have been centred around working with human patients and with recognised methodology so it can be compared like with like with other studies.

This week an article in “Nutraingredients.com” covered a meta-analysis of over 3000 research papers, reducing down to 11 human studies. Meta-analyses is a comprehensive analysis of research papers to find comparisons that build evidence that there is a consistent result appearing across multiple pieces of research. This is often the first step when assessing whether larger specific studies are going to be worthwhile. In fact British Sea buckthorn sponsored just such an analysis undertaken by the Medical Research Council here in the UK in 2014. Funding research is never easy, particularly in niche fields of study. In Europe sea buckthorn is grown across Europe on a small scale compared with other fruit crops. Funding for research is competitive and available only where it will develop into large scale pharmaceutical benefit. Hence research is centred where there is a tradition of using the crop on a wider scale – China, Russia, India, with Germany and Scandinavia adding to the global pool of knowledge.

The research paper in question is entitled – “Effect of Sea buckthorn on blood lipid profiles: A systematic review and meta-analysis from 11 independent randomised controlled trials”. The work done by Xiao-fei Guo, Bo Yang, Wenwn Cai and Duo Li of Zhejiang University, China. With over 2 million hectares of sea buckthorn, china has a significant interest in sea buckthorn. Its traditional herbal medicine has used the plants for treatment of cardio vascular disease; burns, dry eye, inflammation, and promotion of tissue regeneration amongst others.

What has made this study important is the fact that it has centred on trials looking at 403 healthy subjects and 514 patients with conditions such as hypolipidaemia which can impact on cardio vascular diseases(CVD). It has highlighted connections which, similar to the MRC meta-analysis, indicate that sea buckthorn may impact on the risk of CVD. Having raised the potential possible outcome of taking sea buckthorn extracts/oils, it has to conclude however that these studies need to lead to a conclusive wider study to develop consistent extract quality, optimal dose and duration of course when taking a sea buckthorn supplement.

All this is helpful, and as my family take sea buckthorn we appreciate the benefits it brings. Sea buckthorn is not the only natural supplement that is caught in the catch 22 situation that  to gain market recognition there needs to be full human clinical trials to be accepted, but until the market demands this there are no drivers for the research to be funded.

The fact that sea buckthorn has been used for centuries and continues to be so shows it has stood the test of time. There are other growers of sea buckthorn in the UK and interest is growing. Access to fresh berry will allow a better understanding of this unique fruit – so I look forward to the 2017 crop with ever greater excitement.

Change for the better

Weather forecasting must be a thankless task. This week frosts matured into snow. Snow that presenting a wintery countryside scene for a day before returning to cold but not freezing conditions. Mixed in with this came flood warnings. The potential of a serious surge tide coming down the North Sea and overtopping sea walls as happened in 2013.

Memories of the great 1953 floods are still alive in older generations in the area. These recent surge tides are testing  our sea walls even though they are much higher at 5m than they were the 1950s. It was with mixed emotions as I walked our wall on Wednesday this week, wondering how we would react to the sea overtopping these walls and flooding the farm. The predicted tide level was the highest in the month at 4.25m. Predicted levels are calculated forecasts. Tides, like weather are subject to many variables of the regional/local climatic conditions. Surge tides are created from this soup mixture of conditions and form a body of water that increases the tide height over the predicted level. The flood warning that we had for mid week this month was based on a real surge but the one thing that turns a incident into a disaster is timing. Thankfully the surge came down the coast adding nearly a metre to the height of the tide – but it reached us at the time of normal low tide. A huge sigh of relief and another escape from the wrath of nature.

This tidal event came in the same week as a GeoEssex event at the new visitor centre on the Naze at Walton on the Naze. This brought together amateur geologists who have a deep knowledge of our local area. This had a real relevance for our farm as the cliffs on the Naze present a natural barrier that holds the North Sea out of our low lying land. These cliffs are full of fossils and their complex geology has gained them the designation of a Geological Site of Special Scientific Interest (SSSI). The downside of this is the issue that geologists want to see the cliffs continually erode so that the geological strata laid down millions of years ago are exposed to reveal fossil content providing research material that indicates our past deep history.

To many local residents, the concept of allowing the cliffs to fall into the sea is upsetting. Our local landscape is special. This erosion has been happening for thousands of years, but now it seems that our generation will see the last of the Naze disappear altogether if nothing is done to slow the process.

The GeoEssex event was therefore one that could have been a standoff between those who want to see “our” cliffs disappear, and those who was to retain their local landscape heritage.

As it turned out, it was a fascinating day. Fossil collecting on the Naze had started as long ago as the 12th century. The Naze is renown for fossil shark’s teeth, but the early collectors were finding the remains of hippopotamus; rhino; tiger and elephant. Animals of a semi tropical fauna completely alien to our recognition of our  environment today. There have been internationally important collections of bird fossils sourced from the clays beneath the cliffs – revealed only because of the erosive tides. The whole concept that this area was originally part of the floodplain of the ancient rivers Thames and Medway when the North Sea was still land is hard to grasp. But presentation after presentation revealed more detail on the size, scale, timeframe of the development of these ancient landscapes into how we see our land today. As a result I can now see our desire to preserve our landscape differently.

Nature is a powerful agent – as we saw this last week with the threat of the surge tide. It is dynamic. Over millenia our land has seen sea levels rise and fall hundreds of feet in depth, completely changing the landmass we know today. This is not something we can change. We can try to retain the bits we cherish with rock sea defences but in reality, over the next few thousand years natural forces will determine the size and shape of our country.

But having said that – reality is now.  The heartening thing that came out of the GeoEssex event – as with the Oxford Real Farming conference the previous week, was the way that people of different opinions come together to discuss, debate and find ways of working together for a common good.

The new year has already started in a similar theme in the sea buckthorn community. Sea buckthorn is largely know for its berries, but growers have long known that the leaf contain rich and valued nutrients. Across Russia, China and the Himalayan region the leaf has traditionally been used for tea. In September 2016 I was asked by german colleagues to dry the leaves from my Siberian, Latvian and German varieties of sea buckthorn plants so they could be analysed. This project was to assess their polyphenol content compared to leaves from other growers. The results are now developing and indicating that the high levels of nutrients are similar from different locations. The challenge now is to see how we can use the leaves. Although leaves have been used for centuries evidence needs to be provided to satisfy both UK and EU Regulation that leaf is safe and offers the health benefits suggested from traditional use . As with the group co-operation that has formed from the GeoEssex meeting on the Naze – so sea buckthorn growers, processors and researchers from here; northern Europe, Scandinavia, Russia, China and US are coming together with knowledge from experience and research in true co-operation. It is what humans do best.

I hope that in the political world those who will be deciding future relationships between countries across the world will also find a similar spirit of co-operation. We might not be able to change the course of nature, but surely we can ensure that we can live together and make change work for the better.

Climate change focus for the New Year

Time flies is a ridiculous saying, but as the new year cranks into reality it is clear this is to be a productive year. Fieldwork may be progressing methodically – strimming the last few rows of weeds; planting out new plants, staking those that need straightening. Routine but all important to give the plants a good start to the year.

We continue to have little rain. When planting in my soil I dig out a metre square of top soil, then use a fork to break up the subsoil down another 250/300cm. The soil at that level is now hard as nails – as dry as I would expect in July. To plant new plants into this soil without cracking the subsoil will deprive the plants of any chance of getting tap roots down into the lower water table. This period of lack of rain is like last spring’s extended period of rainfall. These extremes are difficult to manage but if they are a sign of the future, management tools will become an essential.

Last year the german sea buckthorn crop was effected by low rainfall. German sea buckthorn agronomists have for some time being promoting the idea of irrigating sea buckthorn to encourage better growth and yield. I have resisted the idea as I believe pumping plants full of water will only end up diluting the nutrients in the berries. But long dry weather periods – predicted by climate change scientists, are not going to be good for promoting good growth of sea buckthorn plants. So if I have a crop this year and there is finally an income coming from the sea buckthorn, one of the investments it would allow is the building of a small reservoir to collect rain whenever it comes.

As i drive into work in my diesel Peugeot car I do feel a pang of conscience about climate change. I cannot moan about the outcomes if I contribute emissions myself. Alternatives are out there and I really need to question all aspects of developing this business as to how to limit its use of energy and resources.

Limiting resources is looking for the holy grail of sustainability. The concept was brought home to me very acutely this week when with Ben, I visited the Oxford Real Farming conference. The conference focus of sound science, practical thinking, profitability and looking to the future was very apt as farming peers into a post-Brexit future. The one speaker that inspired me hugely was John Letts. A grower from Buckingham who for the past 15 years has been developing his concept of true heritage cereals. This is not the use of modern varieties of traditional cereals that our grandfather’s use to grow. Modern farming has become a monoculture, growing single varieties of single crops. This concept has provided an environment for diseases and pests to selectively find the weakness in our genetic varieties. In consequence our management techniques are being tested to the limit with weeds and pests becoming resistant to chemicals.

John’s concept has takes mixed sources of old and even ancient varieties of cereals and mixes then all into one crop. This creates a unique and wide genetic diversity which pests and diseases will not be able to grapple with. The yield is not huge at around 1.25 tons per acre, but then the inputs are negligible. the plants scavenge what they can from the soil.Weeds are allowed to proliferate, but these old varieties grow tall and above them. This length of straw has been bred out of modern varieties. At a time when we are looking to incorporate more organic matter into  the soil in order to improve soil health this tall cereal crop provides for this. As a conventional farmer I would expect our fields to deliver 4 tons to an acre. Accepting a yield drop of 60-70% sounds like economic madness. But what John’s crop loses in quantity it is made up for in nutritional quality. This crop is not about feeding the world but as a crop that produces high quality food from minimal resources this is my equation of a truly sustainable crop.

This heritage cereal presentation followed one that focused on whether organic food really offers a health benefit over a conventional crop. The principle comment I took away from this was that high yield – not unsurprisingly, dilutes the nutrient concentration and thereby nutritional quality. What does this mean for Devereux farm?

For farming to continue profitably we need to find ways of reducing fertiliser and pest/disease control costs. Less cultivations equates to less global emissions – vital in my view. At a time when the President elect of America is declaring himself a climate change sceptic I feel it is all important to find ways to reduce our impact on the environment.
