The six principles of soil health

Much has been written and spoken about the first five principles of soil health. Farmers that are implementing regenerative agricultural practices know the principles, but what they often lack is the knowledge of how to implement the principles on their own farms.
 
It is impractical to merely copy the practices of your next-door neighbour and hope for the same results. Your management style, your soil, your rainfall and your goals are very different from theirs.
 
So, where do you start?
No one knows the context (makeup, conditions etc.) of your farm as well as you do, especially if it is a family-owned farm that has been handed down through the generations. Without the institutional knowledge of your farm, gained over the years, a consultant, sales representative, scientist or academic would be hard-pressed to accurately determine the methods or measures you need to introduce so that you farm more productively.


We all agree that scientists and academics are very knowledgeable about the nature of a specific area or system, but science in general needs to be refined to a level where it is understood and can be measured. It is very seldom holistic, where systems are integrated into a single one-size-fits-all unit. If we take the modelling systems that are in place, for example where the effects of climate change are measured, one small error in calculation will compound over the years, inflating the magnitude of the disaster. This often leads to scaremongering tactics, so be very wary of believing every tale of doom without first checking the facts.
Nature is a wicked system. If it does not feed you, it wants to kill you.

The WHY
We often look at how things are done without questioning why they are done. Asking the question why is important to clarify the reasons behind certain decisions. Why change over to a regenerative system? Why change a livestock production model that has proved sustainable over the last couple of decades? To fully comprehend your why, it is imperative for you to understand your goals.
 
Where do you want to be in the short, medium, and long term? What do you want to achieve?
 
Our goals change over the years, and a teenager’s goals are probably not what a forty-year-old would wish as a teenager anymore. And what a forty-year-old’s goals are today, will probably change when the forty-year-old is a sixty-year-old.
 
So, how does all this relate to a farming enterprise, especially a family farming enterprise?
 
What must a goal achieve so that the sixty-year-old does not regret what the twenty-year-old chose as a goal? We have all had goals, but they need to be adjusted over time because our circumstances change in so many ways. Life happens, and we must be able to adapt and work on challenges as they arise, but that does not mean your long-term goal must change so drastically.
Jim Collins in his book “Good to Great” talks about keeping the flywheel turning. It gains a momentum of its own but, if you change the direction every year, thinking you have found the new pot of gold, you start everything again, from scratch.
 
“The key to a successful agricultural enterprise is to find the advantage your area has over other regions of the country and capitalise on it” – Allan Nartin
What must you goal encompass?
·         family
·         community
·         environment
·         money
·         workers
The larger your influence the larger your circle becomes, until it grows to achieve provincial or even national status.
 
Changing your thought processes from having rights to having responsibilities changes your goal- setting mindset. If we as a nation recognise that a family, a community, and a country’s citizens have responsibilities rather than rights, then our mindset changes from what is good for me (entitlement) to what is good for everyone, then all of us benefit. Your level of influence will always be determined by the amount of responsibility you are able to shoulder. It is also suggested that IQ plays a role, as those with a higher IQ can generally shoulder more responsibilities. It is a shame that this does not happen. The consequence is we lose abilities that could really help make the country a better place. Instead, mediocracy is celebrated.
 
Your farm’s context is all important in your goal setting, and the context of every farm is different. Your goal setting is determined by your age, which cannot be denied, and that is one reason why it is crucial to understand your context.
 
An older person will have questions like: Who will inherit the farm? Is there somebody who wants to farm the land when I retire? What do I want to leave behind for my loved ones? Do I just want to sell the farm? How much change can I still effect on my children, on my farming enterprise, or even in the community?
A younger person generally wants to change the world and will ask: How can we become more efficient? How can we implement what I have just learnt? The thought of starting a family and having a successful farming career are more prevalent in a younger person’s mind. Questions like ‘how to leave the farm in a better condition than when they took over’ don’t really make the top of the priority list for younger people.
 
In Freiburg in Germany there was a bench with the following engraving: ‘The wood that is chopped today was planted by the great-grandfather and the trees that are planted today will be chopped by the great-grandson’. We need to change our mindset to long term sustainability rather than short term profits.
 
Having a family-owned farm that has been around for generations has certain advantages, like the institutional knowledge passed down through the years. But it can also have disadvantages, where the older generation won’t budge on management principles, saying ‘we’ve always done it this way’.
 
So, how can you formulate a plan to make your farm more productive and sustainable? And how can you regenerate your farm’s soil so that nutrient-dense products are produced, products that are both good for the environment and the consumer?
 
Understanding your WHY
Understanding your why has its challenges and aligning your goal with your why and, finally, with your how, takes time and research. It is time that would be well spent before life gets in your way, leaving you with no time to do it now, or ever because you’ve left it too late in your life. This quotation by Israelmore Ayivor says it all: “Success is not obtained overnight. It comes in instalments; you get a little bit today, a little bit tomorrow until the whole package is given out. The day you procrastinate, you lose that day’s success.”

As Abraham Lincoln said, “You cannot escape the responsibility of tomorrow by evading it today.”

Consider the following points, which are becoming a frightening reality, now more than ever.

  • input costs are rising
  • the global shipping industry is in a crisis
  • decades of chemical agriculture have degraded our soil biology so that we rely increasingly more on external inputs
  • our livestock management has had a detrimental effect on our veld vigour — we are understocked and overgrazed
  • yield!
  • the consumer has access to the same information that the farmer has
  • our weather patterns are changing.

How can we mitigate our risk to ever increasing input costs?

There is no one simple answer, and it depends entirely on your farm’s context. How can you minimise the risk on your farm so that you maintain a positive cash flow? Know what your farm’s advantage is and exploit it. But remember that every paradise has a snake. Know the snake but exploit your advantage.

In the east of South Africa there is generally enough rain to produce a cash crop. The higher input cost is mostly mitigated by the fact that there is always a yield from a harvest that will cover the costs. Even though the costs for purchasing the implements required for a no-till system seem huge, the costs will be covered over time by eliminating the diesel expense.

Stimulating and enhancing the soil biology will also improve the biological services that we get for free, rather than paying for the chemicals to supply the services. We have relied on chemistry to feed the soil for too long and have neglected the soil biology. We really need to understand the complexity of soil biology and how to promote and enhance its natural rejuvenation systems. There is not a single chemical product that can deliver the optimal biological results that are obtained when the five principles of soil health are implemented.


Soil has three main components, structure, chemistry, and biology.  ‘Vigorous biology can overcome imperfect chemistry – perfect chemistry cannot deliver optimal results in the absence of biology.’
 
Trying to squeeze an avocado ripe is futile. We all know that ripening is a process that takes time.  Just the same with soil biology, it is a process that takes time to rebuild. It also takes longer, and is more complex, to build the more brittle its environment becomes. It all boils down to the carbon in the soil – we are a carbon-based life form.
 
Thankfully there are two things that we still get for free and which our soil thrives on. They are sunlight and rain.  Harvesting sunlight for photosynthesis and energy and ensuring that the rain penetrates your soil will enhance your soil biology. Don’t let the rainwater wash away your topsoil so it flows down to your neighbour’s farm.
Through photosynthesis, the plant excretes simple sugars in the root zone, called exudates, and these simple sugars feed the soil microorganisms. This action leads to the formation of a symbiotic relationship between the plant and the soil microbiology, where the plant feeds the microbes, and the microbes feed the plant with various minerals. This is as an on-demand system, similar to the way we currently do it, where fertiliser is applied at certain stages.
 
To highlight the complexity, a maize plant needs 42 minerals to function optimally. Currently, most farmers only give nitrogen (N), phosphorus (P) and potassium (K). The companies and farmers that are really on top of their game use 17 minerals, but this still falls short of the requirements.
 
Can cover crops live up to the promise of reducing inorganic fertiliser? The farmer will have to determine this for himself according to the soil’s requirements.
 
A number of cover crop combinations really work wonders, and an in-depth discussion with the cover crop companies and their technical staff would be beneficial. Don’t just plant a mix because your neighbour is planting that specific mix. His goal and what he wants to achieve is probably different from yours.
 
Remember that your cover crop must be aligned with your goal and your farm’s context. The mixes have various functions, so the in-depth discussion you have will centre around:
·         animal feed
·         cover
·         living root (perennial)
·         compaction
·         mineral deficiencies
·         stimulating soil biology – specifically mycorrhizal fungi.
 
We are normally in too much of a hurry, wanting to see results because we are now doing the right thing. Restoration takes time, but it is worthwhile and priceless. The return of diversity, the improvement in the robustness of the soil, and the overall improvement in the health of the environment, becoming a custodian of the land again, is what makes the journey enjoyable.
 
Understand your context and your why, and the how becomes so much easier. Nobody on the journey of regenerative agriculture has done everything 100% correctly all the time. We need to do, observe, adjust, and let the cycle start again. The principles are always the same, they don’t change, but the application of the principles can change drastically from farm to farm and from management style to management style.
 
There are experts in every field, be it planting cash crops, using all five principles of soil health (context excluded), to breeding programmes where animals that are really well adapted to their area are reared. Go to farmers’ days and listen to the experts — I am not talking about listening to a product sales pitch here, but the experts. Read, watch relevant YouTube channels, participate in pertinent social media chat groups where questions are asked and answered. We are all far better connected now than we were ever before, so use the platforms that are available to you, firstly to learn and, secondly, to teach and show what you are doing. We are all in this together and it is amazing what farmers are doing to improve their situation by observing, learning and applying a system according to the context of their farms.

Celebrating Regenerative Agriculture

Celebrating Regenerative Agriculture

Celebrating regenerative agriculture. Heal the land; heal the people

South Africa is not unique compared to the rest of the world in any sense when it comes to agricultural debt, and the way we treat our most valued resource – SOIL

Background

Currently the agricultural debt is R187 billion – this is double the agricultural GDP. There is a shortfall of R20 billion for the next planting season. One reason being the problems at the Land Bank, and the inability of the farmers to service their production loans – and this after a near record harvest in the 2019 – 2020 season.

Dr. James Blignaut has written an opinion piece in the Daily Maverick – “Investing in unsustainable agriculture is reckless and endangers our future” – 5 August 2020. https://www.dailymaverick.co.za/opinionista/2020-08-05-investing-in-unsustainable-farming-is-reckless-and-endangers-our-future

Are we heading for a collapse in our agricultural system where we hope that government will bail us out? Is agriculture the next fiscal crisis that is going to happen with more severe consequences than any other industry, because our livelihood depends on it?

We know what unforeseen consequences conventional agriculture has:

  • Soil erosion – 3 tons topsoil is lost each year from agricultural land
  • Nutrient deficient food – Thomas, D.E (2003). A study of the mineral depletion of foods available to us as a nation over the period 1940 – 1991. Nutrition and Health, 17: 85 – 115.
  • Starved soil Biology
  • Dysfunctional water cycle
  • Dysfunctional mineral cycles

If we do not change our management system where we enhance rather than destroy our biological services that nature offers for free, our input costs will rise we will become more vulnerable to ever-increasing prices. We must bring robustness back into our farming enterprise. Having only a yield as a measure of success is not sustainable – Banks do not bank yields.

How do we regenerate our soil?

In the process of regenerating soil, the farmer is the most important aspect of the whole chain. There are however certain key points that you as the farmer, owner or manager of the farm must be aware of. This will provide a measure of success in changing your management system to make soil health the primary goal of your farm.

Awareness

The first step in knowing there is a problem, is to recognise the problem.

It you can relate to any of the following, then you do not have a problem and do not need to change anything:

  • You are not affected by drought
  • All your chemical inputs are effective. The chemicals do not harm the environment nor animal or human health
  • You are producing a nutrient dense food.
  • Your water and mineral cycles are functioning optimally.
  • You do not have soil erosion or degradation

Understanding

We must fully understand why we must change; this is far more important than how we must change. If you fully understand the why, the how becomes easier to understand.

Buy-in

You as the farm owner must make the process of regeneration of soil your own. It is nobody’s project. It is not an idea that the consumer can implement on your farm. You must fully buy into the process where you understand the why and how – Ask yourself: what is in it for me?

Ownership

This is your farm. You must make it happen; you are the jockey. Nobody is going to do it for you on your farm. You must apply it. There are people doing it already and we must see how we can build a community to help each other. At the end it is you that must drive the process, on your farm.

Action

Make it happen. At this stage you are probably convinced that what must be done is correct and to the benefit of everyone around you and the environment at large. Now you just must take the action and make it happen.

The other five principles of soil health are about HOW we achieve:

Minimum soil disturbances – both chemically and mechanically

We must acknowledge that we are working with a degraded resource – soil. Our management practices have been of such a nature that we have starved and destroyed the soil biology, and the structure of our soil with modern agricultural practices.

I have written about quite a bit about the five principles of soil health. Read more here

Soil cover or armour

Erosion – Caused by wind and rain

Temperature – Bare soil is always hotter than covered soil, and the variation in temperature is detrimental to the soil biology

Diversity – in all aspects

The bigger our diversity becomes the more biological services we will activate. The more robust our farming enterprise will become in terms of:

  • Plants
  • Animals
  • Insects
  • Birds
  • Trees
Living Root

Having a living root on your cash crop fields via cover crops, companion cropping or inter-seeding, feeds your soil biology for longer. This stimulates a larger variety or diversity of soil micro-organisms, that in return improve your soil health.

Integrating Animals

On your cash crop fields, either by eating the stover, or more advantageously cover crops. The symbiotic relationship between grazing ruminates and root and plant stimulation, has been proven by various farmers world-wide. The anecdotal evidence where the biomass growth, and the hay harvest has doubled in certain instances.

How does all this fit together and why should we bother?

What I do, however, want to mention is the advantages of Mycorrhizal fungi and how can we establish Mycorrhizal fungi in our degraded soil.

Mycorrhizal fungi form a mutualistic symbiotic relationship in the rhizosphere of plants. The fungal hyphae allow a larger volume contact with soil. Mycorrhizal fungi are transport “highways” for the plant to transport water, minerals, and various nutrients to the plant. Mycorrhizal fungi are also thinner than root hairs and can therefore penetrate smaller cracks in the soil to access water in the soil that would otherwise not be available to the plant. The symbiotic relationship between the plant and the Mycorrhizal fungi is then completed. The plant “pays” for the biological service that the Mycorrhizal fungi gives, by supplying various root exudates to the microbial world beneath our feed.

Through photosynthesis, the plant captures light energy and converts this to chemical energy. Chemical energy transforms into a carbon-based molecule which nourishes and sustains most living organisms on the planet.

6CO2 + 6H2O = C6H12O6 + 6O2 – is the most important piece of chemistry in the world!

The simple carbon glucose molecule formed in photosynthesis is the basis for our entire food chain.

Soil health and our survival

No feature on earth is more complex, dynamic, and diverse than the biosphere, the layer of living organisms that occupy our soil surface and chemically unites the atmosphere, geosphere, and the hydrosphere into on environmental ecosystem within which millions of species, including humans have thrived. – Green Cover Seed – Soil Health the sixth edition.

It must become clear why the soil biology is so important for our survival – and why the destruction of it is so detrimental for all living species on earth including humans.

Books often mention how important Mycorrhizal fungi is. But how can we restore Mycorrhizal fungi and more importantly how have our conventional agricultural practices destroyed Mycorrhizal fungi.

The importance of Mycorrhizal fungi

Mycorrhizal fungi consist of hyphae, and these can increase the root surface area of the specific host plant by approximately forty times. As mentioned before, the Mycorrhizal fungi receives its energy from the host plant in exchange for all the various minerals, elements, and water that it transports to the host plant. This exchange can only take place when the host plant photosynthesis. So, if a monocrop, soy, corn, or wheat does not photosynthesis it cannot feed the Mycorrhizal fungi anymore. That is of course assuming that there was Mycorrhizal fungi in the first place. Remember we are working with a degraded resource, our soil.

The Mycorrhizal fungi has enough energy stored in its hyphae to survive for about one month if the host plant does not excrete any root exudates anymore. It takes three months before the crop is ready for harvesting.

If we only plant monocrops, and then leave the field fallow until the next season, we risk the chance of any living Mycorrhizal fungi left form the previous year. If there are any fungal spores in the soil these will sporulate when they come into contact with a living root, but as is obvious the fungal spores will diminish each year, as each year the fallow period is too long to sustain the sporulated hyphae.

Therefore, the fourth principle is so important, to keep feeding the Mycorrhizal fungi through the fallow period.

The problem with inorganic fertiliser applications, is that we are giving the cash crop plant the basic elements and minerals that they need. This is normally done in excess, the plant does not have to excrete root exudates anymore, as it has enough nitrogen, Phosphorus, and potassium – this also starves the soil biology. This is where the microminerals, and various other vital elements and minerals that healthy plants need, are not transported to the cash crop plant anymore. We wonder, then, why we produce nutrient deficient food.

Hyphae are thin strands, thinner than root hairs, which can enter cracks that are small for a root hair to penetrate. This however also does not make them strong, and tillage destroys the hyphae. You are breaking your soil’s ability to communicate – remember bacteria cannot move, they signal. The hyphae are the “vessels” through which the water, elements and minerals are transported. You have destroyed your underworld highway.

The problem with conventional agriculture, is that we are destroying our soil biology. The two examples given, are sufficient to see that if this is done year in and year out that in a brief period we have destroyed our Mycorrhizal fungi. We have diminished the fungi spore count in the soil so that it is no longer viable.

How can we change our management practices?

So how can we change our management practices to enhance and to improve our soil biology especially Mycorrhizal fungi? Please remember, regenerative agriculture is never a sole product or a single change. Everything is connected, and everything you do influences the environment. Nothing happens in isolation.

As mentioned before, we are restoring a degraded system. One of our aims should be to build-up our soil biology so that the Mycorrhizal fungi is so abundant that it produces spores again.

The hyphae never touch each other and will always branch away from each other. Once they become so abundant, that they cannot branch away from each other, they will then start making spores. It is obvious that the smaller the area, like a pot plant, will start producing spores much quicker than on an open cash crop field.

On an open cash crop field, it can probably take up to eighteen months before the hyphae are so dense that they start making spores. How can we achieve eighteen months of minimal disturbance, having a living root, 24/7 365, having armour on the ground, and plant diversity? The answer simply becomes: A perennial cover crop. To give that specific land parcel, the best chance to restore its resource, namely soil biology.

The integration of the animals now becomes easy, as the animals will harvest the cover crops to mitigate the cost of the cover crop.

It is also obvious that not all your cash crop fields can be done during the same year as you still need an income.

It must also become obvious that the crop rotation is no longer between two, three or four crops, but it is a crop and perennial cover crop rotation. There is a farmer that has a twelve-year cycle, of which eight years is a perennial pasture. The pastured is grazed multiple times during the wet season, and once during the dry season. The last grazing is done mechanically in the wet season, for hay.

Regenerating your soil biology is a management system, it is not a single event, nor is it a specific product. It is a combination of various management principles that when implemented, work together with the common goal of restoring the soil biology. If you have implemented one of the principles of soil health, it does not mean that you have now become a regenerative farmer. Rather apply the constant implementation of all five principles.
