John’s Recommended Reading List

“The mind, once stretched by a new idea, never returns to its original dimensions.” ~ Ralph Waldo Emerson

I believe constant learning is an imperative, and should be enjoyable. I find learning new things about life and living processes to be exhilarating and exciting. I have read hundreds of books and thousands of papers that relate to agriculture and living systems in some manner. Of course, the areas of science that touch agriculture in some way are so large it seems certain we will never run out of new things to learn.

I find it intriguing that much of the emerging foundational science which promises completely different approaches to agronomy and agricultural management is not coming from people who are closely connected to agriculture but in other life sciences. Very often, the implications of their work are not directly spelled out, but when we connect the dots, we realize how powerful this new information will be in the future.

Our present mechanistic approaches to agriculture since the “Green Revolution” have been based primarily on chemistry and genetics. I very strongly believe the agriculture and agronomy of the future will be based on biophysics and a very different understanding of the organism. All growers and agronomists should have a working knowledge of the concepts and principles in this domain since they are the foundation for the agricultural revolution that is happening now.

Many people have asked me for a recommended reading list of the most pertinent and valuable books I have read. This list is a live list of books that I continue to update.

I have divided them into different (somewhat arbitrary) sections based on how accessible they are and their general topic area.

My preference is to have post-it flags within easy reach as I read, and mark each page with a flag that I want to use as a reference in the future. It is easy to observe how useful a book might be based on the number of flags it has. Most of the books who made it onto this list have hundreds of flags. For the very few which have fewer, they are still on the list because of the importance and relevance of their message.

Foundational Soil & Plant Science 

This group of books is very accessible, from my perspective any serious grower will have at least half of them on his shelf. These are pretty much in the must-read category for farmers who want to begin thinking differently and prepare for the agriculture of the future.

Exceptional Peer-Reviewed Soil and Plant Science References

The books in this group are written by and for academics, rather than for growers, but the information they contain is gold. How much is it worth to you to have a reference book that can tell you precisely why a certain disease organism is showing up, and how you can create an environment so that it is no longer present? If you are an agronomist or a consultant, each of these is a must-read. Reading these books will change how you approach managing soils, crops, and pests.

The Biophysics of living organisms, with strong agricultural implications

The coming agricultural revolution which will supersede the “Green Revolution” will be a revolution of biophysics. We are reaching the limits of chemistry. The information contained in any one of these books will require us to shift our thinking and approach to growing crops. Some of these are more accessible than others. Any one of them will have you on the edge of your seat as you understand the implications.

The ‘culture’ of Agrarian Culture

“People laugh at me because I am different. I laugh at them because they are all the same.” ~ Gabe Brown

The present model of commercial agriculture has adopted a very mechanistic worldview and ethos, with little room for ‘culture’. As we implement more regenerative models our cognition changes. We are present with our plants and livestock in a different way. We begin thinking about the ecosystems we work within, and how we can enhance them. This culture of caring is what consumers associate with farming culture. There are many good books that would fit into this category. Some are exceptional. Here are a few of the exceptional ones.

The marvelous pigness of pigs – Joel Salatin  (A must-read)

Homeostasis

Homeostasis is one of those nice words we do not hear much nowadays. It means the body’s ability to balance itself. ~ Charles Walters1

Homeostasis is universal. All biological systems maintain homeostasis. They respond to changes in their environment and regulate their internal processes to adapt.

Maintaining body temperature is a homeostatic process, as is maintaining leaf temperature for a plant. Or leaf hydration. Or the concentration of nutrients.

Yes, plants regulate the presence of nutrients throughout its entire structure.

When soluble phosphorus fertilizers are applied to soils, all the micro-organisms with a proclivity for solubilizing complexed mineral phosphorus shut down. There is no need to expend energy to solubilize that which is present in excess.

When soluble nitrogen fertilizers are applied, soil micro-organisms with the capacity to ‘fix’ hundreds of pounds of nitrogen per acre per year shut down completely.

Halt these homeostatic processes and future dependencies are created, because the natural processes are now dysfunctional.

Some soil processes we may not immediately associate with living organisms also demonstrate homeostatic effects.

When clay colloids contain a surplus of a given cation, sulfur applications release primarily the cation in excess supply. When calcium and potassium are adequate but magnesium is excessive, applications of gypsum or sulfur will remove primarily magnesium from the colloid, and not calcium or potassium. When potassium is in excessive supply on the colloid, potassium will be the first to be removed. One could say that clay colloid mineral balancing can be homeostatic.

Humic substances are known to provide a pronounced increase in plants and soil biology homeostasis processes. Of particular interest is their capacity to increase plant defense mechanisms2 and mitigate excess salts3.

Significantly, humic substances also affect the activity of prions4 and endocrine disruptors5, which encompasses many synthetic pesticides. This indicates that the integrity of soil or gut microbiomes which are suppressed by pesticides can be improved by the presence of these compounds. This is homeostatic regulation of the environment for optimal microbial development.

You can harness homeostasis to the benefit of your crops, your soil’s health and your profitability, or ignore it to your detriment.

Close Connections

When we try to pick out anything by itself, we find it hitched to everything else in the Universe. ~ John Muir

What does it really mean to find everything connected to everything else?

You may have heard of the idea of six degrees of separation between you and any other person on the planet1. It has been validated that within the United States, you are separated by only three degrees from any other person. If you are in the US, you can reach anyone else in the US as a friend of a friend of a friend. Three connections. No wonder the world seems such a small place.

How is this relevant to biotic communities? How many degrees of separation exist between a wheat plant in Kansas, and a salmon in the Columbia River? Between a maple tree in the Appalachians, and a grizzly bear in Alaska? I would submit there may be far fewer than we might guess. When we consider the microbial community that moves in the air, on birds and insects, and through water systems, many of the trophic biospheres are likely very closely connected.

When we manage soil health and the farm ecosystem so that biological populations flourish, what might be all the impacts in the greater ecosystem we haven’t identified yet? When your soils contain biology that synthesizes antibiotic and growth-promoting factors, how might that influence the streams and the rivers?

What actually produced the difference?

When observing changes on farms, we give credit to the wrong factors at least half the time. ~ Gary Zimmer

A foundational premise of holistic agriculture is that the whole is greater than the sum of its parts.

This means that we can’t understand the whole by only analyzing the parts.

Herein lies the challenge of using single-factor analysis research to study agriculture.

There is really no such thing as a field trial where you only change one variable. When you change one thing, many other things change in the system. If you change the quantity of an applied nutrient, the microbial population shifts, root development changes, and the soil microbiology/plant symbiosis dynamics change completely, with cumulative effects that can show up on other crops in future years.

In such an intricate and integrated system, it is easy to assign credit where it may not be due, both when things go well, and when they don’t.

When Quality is the goal, Yield is a result

When yield is the goal we focus on, we manage plant nutrition to produce the highest yields possible. It becomes strictly a numbers game, making certain the crop has adequate quantities of water, sunlight, nitrogen, potassium, phosphorus, and possibly other nutrients to reach our yield goals.

Soil health and microbial populations are discounted and disregarded, as they are not perceived to contribute to yields.

Of course, this approach generates a lot of externalized costs to the environment.

A better approach is to focus on producing quality.

The goal is to achieve both exceptional quality AND yield. This is not a case where we can only achieve one at the expense of the other. We can achieve both at the same time.

When we produce crops with higher test weight, protein content, sugar content, fat content, soluble solids, shelf life, storability, or whatever metric defines quality in the crop we are producing, we begin thinking differently about how we manage nutrition. Soil health and microbial populations become important considerations. It is necessary to manage calcium, magnesium, sulfur, and a dozen additional trace minerals.

This approach generates a lot of external benefits to the ecosystem. Pest pressure is reduced, carbon is sequestered, soil health is regenerated.

Best of all, when plants become vibrantly healthy, you can’t stop yields from happening.

The healthiest crops are the highest quality crops. And also the highest yielding.
