Soil Health

Will Godwin – Hampton Estate

Will Godwin – Hampton Estate 1440 1079 Soilmentor

The beautiful family run Hampton Estate is nestled in the sandy soils of Seale, near Farnham in Surrey. Most of the farmland is in woodland or grass and twenty years ago Guernsey dairy cattle grazed the estate. The family have since switched to a Sussex cattle herd and started producing grass fed beef to sell direct to their local customer base. Their cattle are raised on tasty grass and lovely Surrey sunshine! Hampton Estate are members of the Pasture Fed Livestock Association and in the process of having their beef pasture for life certified. Pasture fed systems with good grazing management can be very regenerative for soil health. Hampton have started using Soilmentor to monitor and understand how soil health is changing across their farmland.

The estate has some very special gardens filled with hops! This speciality crop has been grown in the local area for hundreds of years, despite a lot of production being wiped out by a fungal disease called verticillium wilt. Many other farms gave up their hop gardens, but Hampton has maintained growing this traditional crop with high biosecurity measures. Their hops are used in three major breweries across the country. The infrastructure required to grow hops is extensive and to fit in with the natural landscape Hampton uses tall poles made of chestnut from their own woodland.

Hampton are developing their farm strategy around building soil health and improving their sward. Using Soilmentor they can create a baseline for where their soil health is at now and give them an idea of where they want to go. Growing good grass is essential for their pasture fed cattle and so one approach they will take is to increase species diversity and deeper rooting plants in the sward. This will increase their resilience in times of drought as deep roots can reach water and nutrients further down in their sandy free draining soil. A more diverse range of broadleaf plants and root systems will increase the potential to sequester carbon from the atmosphere and put it into the ground. Hampton is monitoring the % of different plant species and their density to see how this changes over time in their pasture fields. As they collect more information about their pasture with Soilmentor they will be able to compare plant species readings with soil structure and earthworm readings to see if there are any trends and links in their improvement.

“I’d been looking for a tool to monitor soil health just like this, I’d tried other tests but they were always so complex and involved lab testing. It’s great to have a set of simple tests that I can do easily myself.” – Will Godwin, Hampton Estate

We spent the day soil monitoring pasture fields under different management approaches with Will Godwin. Will is part of the estate management team and works very closely with Bridget and Bill Biddell who own and manage the Estate on behalf of the wider family. Heading out to the field with Will and Bridget was great fun and the excitement about digging holes and hunting for worms was palpable! Will had expertly crafted an infiltration rate pipe from a piece of drainpipe, sharpening one end to make it easier to get into the ground. He used an old water bottle with 444ml of water marked on it to ensure the exact same amount of water was used each time. An old dustbin lid made an excellent examination tray for the soil block and Bridgett didn’t seem to mind us using her freezer bags to collect samples for the slake test!

We started on a very sandy permanent pasture field grazed throughout winter by their steers and very poached up in places. On this field we found no worms at all! This meant Will recorded an earthworm count of 0 in Soilmentor and we all agreed this is definitely an opportunity to improve how the soil on this field is managed to increase earthworms for the next time it is monitored. Next we headed to a permanent pasture field being rested after grazing last year which had an abundance of wigglers, seventeen in one soil pit, and even a dung beetle popped its antlers up. At the time we didn’t realise it was a dung beetle, but took a photo of it using Soilmentor so Will could look back at a later date to identify the beetle. This field had a dense thatch of grass on the surface which slowed the infiltration rate down considerably. The third field we tested was a grass field cut every year for hay which had a few worms but an exceptionally fast infiltration rate. In addition to these fields Will plans to monitor two more pasture fields and one hop garden.

Going forward Hampton plans to start a new grazing system, to improve sward quality and soil health across the estate. Changes in the way the herd is managed and trying mob grazing to encourage tall grass and deep root growth are central to the strategy. Over in the hop gardens, although they cannot return the biomass from the hop plants back to the soil due to the verticillium wilt disease risk, there are plans afoot with Rob, their Agronomist, to plant green manure cover crops in between the rows of hop plants. Verticillium wilt only affects broadleaved plants and to avoid attracting it to the garden the cover needs to be a cereal to mitigate this risk, so rye and oats are good options. The cover crop will anchor the soil, protecting it from erosion, photosynthesising and putting nutrients into the soil.

Soilmentor will help Hampton monitor how their soil is changing as they experiment with new farm management approaches to improve soil health. For example, with a new approach to grazing the fields over winter, such as mob grazing, Hampton will hope to see an improvement in earthworms, sward density and soil structure. All of these are what we call ‘soil health indicators’ and are easily monitored using soil tests with Soilmentor. All the information Hampton collects using the Soilmentor app is visually displayed on their online account making it easy to look back at their soil health records and analyse how things have changed over time.

What are Will’s management objectives:

  • Improve soil health across the estate
  • Increase grass and broadleaf species
  • Understand best grazing technique to optimise grass growth

What is Will monitoring:

  • Earthworms
  • Infiltration
  • Slake (Wet aggregate stability)
  • VESS (1-5)
  • % of undesirables % of bare soil
  • % of grasses, broadleaves, no. of species of each

Soil Test Challenge

Soil Test Challenge 559 397 Soilmentor

Try something new this year, start monitoring your soil health. Do you accept the Soil Test Challenge?

We challenge you to do 3 easy soil tests on your fields. It takes one day in total and will give you valuable insight into how healthy your soil is and how well it will support healthy plants and livestock.

Knowing your soil is the key to successful farming, so take the time to do these simple tests and improve your understanding of your soil health. It will help you to develop the right approach to manage it.

Soilmentor makes physical soil analysis easy and informative. It works with a handy smartphone app to record soil test results & photos in the field and an online account to review & analyse a range of soil health indicators.

 


How to participate in the Soil Test Challenge:

Before you start:

  1. Pick 3 fields to test, repeat the tests 3 times in different locations on each field.
  2. On the day you do your tests, take a note of the weather over the last 24 hours because the temperature and amount of rainfall will affect the outcome of the tests.
  3. Take photos of each place that you test and record the results of each test (do this easily with Soilmentor). This helps you to monitor change over time and is important if you want to get advice further down the line.

 

TEST 1 – Earthworm Count

Earthworms are a key indicator that your soil is alive and has good soil organic matter content. They move nutrients around the soil profile, playing a vital role in feeding your plants, and open up the soil structure allowing water and air into the soil. Their sticky mucus also helps to build good soil structure.

Equipment: spade and tray or plastic bag

Method: Dig a 20 x 20 x 20 cm hole with your spade. Place the dug up soil on the tray/ plastic bag. Using the app, take a photo of the soil profile then gently break it apart with your hands. Count the number of worms and record it using the Soilmentor app. Take a photo in the app too!

In the UK, an average of 15-20 worms in a 20 x 20 x 20 cm soil pit is considered good, but it will also depend on the time of year and your soil type, and any recent field management. Using Soilmentor makes it easy to look back and compare when you do the count again next year.

 

TEST 2 – Slake Test

How well your soil structure holds together in water shows you how it withstands heavy rainfall, and what its capacity for storing water and nutrients is like. Good soil structure is an indicator that you have adequate soil organic matter that supports the life in your soil.

Equipment: spade, sieve with small mesh (>2mm), bowl of cold water, stop watch, plastic bags x9 (can be old shopping bags), pen and paper for labelling soil samples

Method: Take some of the soil from the sample dug up for the earthworm count or dig up a new sample. Select 3 pieces (aggregates) which are roughly 1 cm in diameter. Put them in a plastic bag, write the name of the field on the paper, tear it off and put it in the bag. Take care not to squash the soil. Repeat this process for all the soil samples you take. Take all bags of soil home and take the soil out and allow it to air dry overnight in a warm place being careful not to mix up the different samples. The next day, for each sample, arrange the soil aggregates in the sieve and fully immerse in water up the lip of the sieve. Observe the aggregates under water for 1 minute and lift them out then score them using the scale on this webpage. If they score 0-2 the test is over and you can record the score in the Soilmentor app. If they score higher than 2, move onto the second part of the test: gently raise the sieve up and down five times, so that the surface of the water just touches the top of the aggregate. Score using the scale and record in the Soilmentor app. We only give a soil a score of 8 if the water is crystal clear (i.e. the aggregate has not broken down at all) after the test. Take photos of each slake test using the Soilmentor app.

Well-structured soil is composed of rounded aggregates which will not break down easily in water. This means soil will retain its structure after heavy rainfall, and allow water and nutrients to move between the aggregates into deeper layers of the soil for your crops to use later.

Aggregates that often have sharp edges and that break down easily in water may suggest that they are only held together because of compaction. As soon as there is a heavy rainfall the soil structure falls apart and blocks the soil surface increasing the likelihood of surface run-off and erosion.

 

TEST 3 – Infiltration rate

Infiltration rates clearly show how ready your soil is to soak up water. If the soil structure is open with plenty of air spaces the water will easily move down into the soil profile until the air spaces are full with water. Nutrients also move with water into the soil profile.

Equipment: 150 mm x 150 mm metal/plastic tubes with 85 mm depth marked (find out how to make this), water bottle with 450 ml marked on it, water (4L or so per field), stopwatch (on phone), mallet (for driving tube into soil) & wood block (to protect the top of the pipe from damage when hammering in)

Method: Clear plant growth from the soil surface by trimming back. If sward is very thick try cutting through with a knife to help get the tube through. Insert tube into the ground to a depth of 85 mm. Use the app to take a photo of the location showing the tube and groundcover. Fill your pre-marked water bottle with exactly 450 ml of water. Pour water steadily into the top of the pipe and start stopwatch. Stop timing when all the water has disappeared but the ground is still glistening and record the time in the app. Measure out another 450 ml of water in the bottle and repeat the remaining steps, recording the time in the Soilmentor app.

Infiltration rates for each field help you to understand how easily water and nutrients can move into your soil. Very slow rates may indicate waterlogging, soil sealing and compaction, whilst very rapid rates may reveal an increased risk of nutrient leaching.

Recording soil test results

Make soil monitoring easy by using Soilmentor; record soil test results at the touch of a button and upload the data in seconds for analysis on your online account via an internet browser on your phone, tablet or laptop.

We want to see your soil test photos from the #SoilTestChallenge! Either tweet them to us mentioning #SoilTestChallenge @soilmentor, or send us an email to info@vidacycle.com.

 


 

To get the most out of soil monitoring repeat soil tests twice a year and more, around April and October when the weather should be warm and the soil is moist. Different farm management practises will influence the results of these tests, so if you’re trying anything from conventional arable to cover crops to mob grazing, it is essential to monitor your soil.

Chris Leach – Waddesdon Estate Farm

Chris Leach – Waddesdon Estate Farm 4032 3024 Soilmentor

Chris Leach is part of the Forestry Team at Waddesdon Estate in Buckinghamshire. Around 500 tonnes of wood is produced from managing the 450 acres of the estate’s woodland, half of which is used as fuel for the biomass boiler. Chris was keen to find an environmentally sound way to use the waste wood and saw the perfect opportunity to work with the Estate’s farming operation to combine the waste wood and farm waste to create compost. He will add bokashi to the compost which he hopes will encourage mycorrhizal fungi and beneficial bacteria in the soil. Chris is now working with all departments on the Estate, (Gardens, Stud, Forestry, Farm), to improve and sustain soil health.

By recording information on soil tests with Soilmentor, Waddesdon created a baseline starting point as well as a future goal for what the estate team want to achieve. Chris finds testing water infiltration rates most interesting as one of the estate’s aims is to increase the soils capacity to store water and make it more resilient to drought. Doing the VESS test has highlighted how much topsoil they really have and the difference between arable fields and permanent pasture.

Chris said “Generally the lack of earthworms across the whole estate was a surprise, we would love to see an increase. Soilmentor is so simple – it’s an amazing tool. I find the app extremely easy, I record soil test results on my phone and when I get back to office it’s all there in one place on the computer. It makes you look at things a bit differently, giving a wider picture, something to reference and understand how to improve. All Heads of Department can access the data online too so that now everyone is working together to improve soil health across the estate. We are always learning and want to share our knowledge for the present and the future. I spout regenerative agriculture at every opportunity, even when I’m talking to other parents at my son’s football matches!”

Chris’s management goals

  • Improve soil health and build regenerative farming system
  • Improve profitability
  • Reduce chemical inputs
  • Disturb the soil less

What is Chris measuring?

  • Infiltration rate
  • Earthworms

How do rhizosheaths tell the story of soil health?

How do rhizosheaths tell the story of soil health? 1080 1080 Soilmentor

If a plant has a large quantity of soil clinging to its roots, where the roots appear brown and not white, this soil coating is called a rhizosheath.

Why do we love them so much? They are an indicator of life in the soil: of biological and microbial activity in the rhizosphere, which is also known as the root zone.

Micro-organisms feed on root exudates and secrete binding agents which hold soil particles together around the roots in an aggregated structure, which indicates good soil health.

Soil structure is aggregating around the roots (photo from Niels Corfield https://twitter.com/niels_corfield/status/1070304660374855685)

“A simple way to find out what healthy soil looks like in your fields is to pull up some weeds! Don’t be surprised if you find rhizosheaths on these roots; weeds are often the healthiest plants in your soil.” – Niels Corfield, Soil Health Advisor

Watch the video below to find out how to assess rhizosheaths in your soil:

Fred Price, a regenerative farmer, describes how rhizosheaths indicate good soil health: “Seven years ago I didn’t know roots could look like this (see photo below)! The biological component of our soils mediates the soil-plant interface, increasing availability of nutrients and resilience to biotic and abiotic stress. So a well developed rhizosphere, the zone of plant influence in the soil characterised by root exudates, microorganisms and indicated by a healthy rhizosheath, is a great barometer for a highly functioning soil ecosystem. This vitality reduces the need for synthetic inputs, allowing the biological component to flourish further – this positive feedback cycle underpins any regenerative farming system.”

Rhizosheaths at Fred Price’s farm

Soilmentor can be used to monitor the development of rhizosheaths – you can score your progress in the app! Learn more about scoring your rhizosheaths with Soilmentor here

We plan to develop this scale to be more nuanced, so if you’ve been observing rhizosheaths in your soils we’d love to hear from you about your experience – info@vidacycle.com.

Know your Soils #12: The Soil Health Principles 5184 3456 Soilmentor

Welcome to the twelfth, and final, instalment of our Know your Soils series sharing practical tips for monitoring the soil health on your land.

“If you can’t measure it, you can’t improve it.


7 Soil health mantras to follow on your farm

Insights from Niels Corfield, Soil Health Advisor

How do you build soil health? Below we share the six soil health principles to follow on your farm. Implementing farming practises and any new ideas which encompass as many of these principles as possible will get you firmly on the path of regenerative farming. With every decision you can use these principles as a checklist to guide you to the best tool to move forward to build a regenerative farming system.

 

 

1. Living Root

Living plants have living roots, they photosynthesise and transmit energy into the soil. This energy is feed for the beneficial soil organisms at work, creating aggregation in the soil.

2. Covered Soil

It’s best to have living plants in the soil, as then you have living roots. But the next best thing is to ensure you cover ground with plant residue, e.g. with a terminated cover crop

3. Minimise Disturbance

Ploughing disturbs the soil organism population, preventing them from doing their necessary work to maintain healthy soil. Reducing cultivation or going no till keeps them happy!

4. Diversity

A diverse range of plants in the soil means a diverse range of roots and a diverse diet for the soil organisms the roots are feeding. Roots have unique functions e.g tap roots bring nutrients up from deep in the sub soils and legume roots fix nitrogen directly in the soil.

5. Feed soils

Feeding the soil with compost, manure or compost tea will directly increase soil organic matter levels and provide plenty of food for worms!

6. Incorporate Animals

Grazing livestock in a rotation is beneficial for increasing soil organic matter, terminating cover crops and decreasing weeds in your fields. Why not try mob grazing?

7. Minimise Chemicals & Synthetics

Adding chemicals can undo the good work you put in for the principles above — pesticides kill soil organisms, fertilisers make plants dependent and herbicides kill living roots.

 

 

Microbial activity in the soil will lead to good soil structure; if generally improving soil health is your first objective then fostering microbial activity is a good place to start. Feeding microbes directly with manure or compost is one way to do this, or encouraging grass plants to grow bigger faster is another. Different grazing practises offer ways to achieve this too.

What management practises have you found useful for building soil health? We’d love to hear from you – send us an email to info@vidacycle.com

Hannah Steenbergen – 42 Acres, Somerset

Hannah Steenbergen – 42 Acres, Somerset 5184 3456 Soilmentor

Hannah Steenbergen is the farm manager at 42 Acres Farm , a 170 acre working farm and garden which is home to the 42 Acres Somerset Retreat Centre. Until this year much of the land was untended and wild, so there is an amazing amount of wildlife. Hannah’s plan is to create a small-scale diverse regenerative farm where they use minimal inputs, foster biodiversity and increase the fertility of the land.

“After we made hay the field was a buzzard playground! Hay making revealed all these small mammals. There’s amazing wildlife at the farm, we want to keep it that way whilst also bringing the land into production.” – Hannah, 42 Acres

On the farm she has introduced a small beef herd of Shetland cattle, which are 100% grass-fed and managed with ‘mob-grazing’.The garden, greenhouse and polytunnel are filled with delicious vegetables, salads and plants grown by Head Gardener Arek. There’s also a flock of Khaki Campbell ducks waddling around the garden and laying eggs. Hannah grew up on a biodynamic farm in North Yorkshire and is committed to following regenerative agriculture principles as she takes the 42 Acres farm forward.

The aim is to build soil health through clever grazing management with their growing number of livestock, moving them around the pasture regularly, ensuring grass has time to regrow and organic matter is continually incorporated into the soil. The farm is in a very wet area, so increasing the soil’s capacity to hold water is very important, that way they can prevent run-off and keep topsoil and nutrients on the land.

The Soilmentor app allows Hannah to monitor how the soil is changing, and if she is in fact moving towards her goals to build soil health at the farm. Her first soil tests clearly show where she started, and with testing every 6 months, she will quickly get an idea for how the soil is changing with each new farm decision and management practise put in place. Plus it can be fun! Hannah said “I particularly enjoy the earthworm tests, identifying the different types of earthworms is very interesting. The infiltration rate is also very interesting, it was completely different in our pasture vs roto-tilled veg plots. I feel like I’m understanding more about soils all the time.”

For Hannah it’s very important to become a financially viable small scale and diverse farm, with a social impact. As the farm is in its first year, Hannah and the team are figuring out what the land would be best used for, and the soil tests will give a good indication of things to try out. By monitoring and understanding the soil health now, she has taken important first steps to ensure healthy soils on the farm.

 

What are Hannah’s management objectives?

  • Increase soil health on the farm
  • Understand best grazing techniques and optimise grass growth
  • Maintain and increase biodiversity above and below ground

 

What is Hannah measuring?

  • % of undesirables % of bare soil
  • % of grasses, broadleaves, no. of species of each
  • VESS (1-5)
  • Earthworms
  • Infiltration
  • Plate meter

How to visually assess your soil structure

Short video created by the Soilmentor Team

Assess the quality of your soil structure for yourself with a spade, tray, ruler and smartphone. Soil structure shows how much biological activity is happening, how well water can infiltrate downwards and how well plants are being nourished. It is core to soil health!

It takes some practise! This short video will show you what to expect:

 

Scoring your soil sample with the VESS chart

Once you have measured the top and bottom depths of your sample, you need to score each one using the VESS chart.

When scoring your sample the VESS guidelines encourage you to ask yourself: Are the clumps angular? Do they have roots running through them? How easy is it to break them down? How porous are they? With gentle pressure breaking them down what size are most of the clumps?

We found many farmers find these questions quite difficult. In the video we simplify the process: it is easiest to observe what soil looks like when you break it apart during the test. If the pieces are mainly angular then give a score of 3-5 and if they are mainly ‘bobbly’ or crumb-like give a of score 1-2. Don’t understand what we mean by ‘bobbly’? Watch the video and you will see! The app helps you with the scoring when you are out in the field too.

 

What does a healthy soil look like?

Well aggregated soil gets first prize in the VESS test! This means that the soil particles are in a crumb structure: there are smaller particles holding together around plant roots.

Soil is aggregated by biological activity; microbes and soil organisms digest organic matter and glue the soil particles together.

Aggregated soil is good because it allows air and water to percolate and store between the particles, which fosters plant growth and supports all soil flora and fauna to thrive.

Soil may lose it’s aggregation structure due to compaction or a lack of biological activity. If you work on improving your soil with the 6 soil health principles you can regenerate it, restoring it’s life and aggregation.

When and how often should you do soil tests?

Soil test calendar created by the Soilmentor team

Taking the first steps on your soil monitoring journey involves some essential decision making! Firstly, which soil tests are right for your farm as well as when and where you are going to do them?

Certain tests are best done at certain times of year, and like most things in farming, this is due to the weather. On the calendar you can see the key soil tests, when and how often to do them. Choose a minimum of 3 of the key tests and ideally do them all on the same day.

Deciding when and how often to do the tests

Deciding which fields to test

If you want to get an overview of how your soil is doing choose fields which are managed differently, for example, one arable field, one permanent pasture, one herbal ley and so on.

A few farmers have wanted to better understand how soil changes across their rotation, or under cumulative years of a herbal ley. In both these cases, choose one field from each part of the cycle to look at how the soil changes over time.

If you are concerned about the performance of different fields choose to test a couple of your worst fields and a couple of your best and then try different management practices to improve the worst ones so they look more like the best.

Choose fields where you can experiment with different management practices and make changes, so that the results from your soil tests can inform what to do next. If you found poor soil on a field under a restrictive stewardship scheme it could be frustrating that you can’t do anything about it.

Most importantly, only choose as many fields as are manageable and which are easily accessible, ideally not too far from each other. Planning to test 3 fields and doing it is better than planning to test 6, feeling overwhelmed, and not doing any!

Where to do the tests on the field

As a basic rule you want to do each test a minimum of 3 times on each field to get a representative sample. It’s important to not do them too close to the edge of the field too. Certain tests such as the plate meter are better conducted more randomly – for these you can also try walking a W in the field and testing along it. 

If you want to get the most accurate representative sample do 1 test every 8 acres in a field, but sticking to the rule of 3s is easier and will give you good results too!

Once you’ve decided on the location of your sample sites within each field, you can add the exact GPS location of the sites into the Soilmentor app, so you can make sure to return to the same sites for a more accurate comparison next time you go out testing! Read more about this feature here.

To remind yourself of the different soil tests you can choose from, and how to do them, see the full list here.

Soil Health – what’s it all about?

Soil Health – what’s it all about? 251 172 Soilmentor

This is the first in a series of blog posts from Jenni Dungait, our resident Soil Health Expert, on the scientific basis for soil tests.

 

Soil health is different from soil quality because it recognises the key role of soil biology as well as soil chemistry and soil physics. Getting soil health right can help farmers to produce food and look after the environment.

Farmers all over the world are starting to pay attention to what is going on beneath their feet. Knowledge of the value of ‘farming soil biology’ belowground is just as important as caring for the crops and livestock aboveground.

You can use the Soilmentor app to record changes in a range of soil health indicators.

If you start monitoring now, this could help get you set up and ready to meet the requirements of the proposed Environmental Land Management Scheme in the new Agriculture Bill.

 

What are the signs that a soil is unhealthy?

We all know the symptoms of unhealthy soil:

  • erosion
  • compaction
  • sealing
  • waterlogging
  • contamination
  • acidification
  • loss of soil biodiversity
  • soil organic carbon loss
  • nutrient imbalance
  • salinization

The map on the right shows Relative Soil Health for the UK and Europe. The scale at the bottom shows the relative soil health score. You can see that much of the UK scores medium to poor. These soils will be showing one or more of the symptoms of unhealthy soil.

Fixing unhealthy soils is costly in terms of time and money, and may cause problems beyond the field boundaries, for example, by contaminating local waterways or emitting greenhouse gases and increasing the carbon footprint of your farm.

 

How healthy could my soil be?

Soils change from place to place, so don’t compare your soil between fields or with other farms.

Start by using a simple ‘Under the Hedge’ test (or Relative Soil Health) to see how healthy your soil could be.

Dig a spade of soil from your field and then another from nearby natural vegetation and compare them using the soil tests on the Soilmentor app.

 

I am very pleased to be working as an independent Soil Health Expert with Vidacycle to develop the Soilmentor app using my knowledge. Watch out for a series of blogs from me on the Vidacycle website in the coming months introducing the scientific basis for the individual soil health tests chosen for the Soilmentor app. If you have any questions you can email me directly at jenni@soilhealthexpert.com
