Ecological agriculture succeeds not through idealized harmony but through understanding nature’s dynamic, often chaotic systems and managing them with intention

In the March issue of this fine magazine, I said something to the effect of “design your system right, and eventually your sprayer will rust away, unused.” Reader feedback started flying in! 

Most of the feedback was from folks who believe that all organic farmers are just lucky. I (and Acres U.S.A.!) are leading people terribly astray with our “pop ecology,” they said. Three people sent me a link to an article by Andrew McGuire called “How Pop Ecology Misleads Agriculture”: csanr.wsu.edu/pop-ecology.

In this month’s article, I’d like address ecological pest control and soil fertility while simultaneously addressing McGuire’s critique. 

Where Credit’s Due

First of all, McGuire has several excellent points. He rightly observes that many people interpret ecological agriculture to mean “If we just ‘work with nature,’ everything will fall into place in perfect harmony.” “Do nothing and the soil will build itself.” “The pests will regulate themselves.” “The yields will take care of themselves.” McGuire is correct to criticize this. This “pop ecology,” as he calls it, is a nice story, but it’s not true. It’s a “Bambi” version of ecological agriculture. 

Now, there is truth behind the idea that when we “work with nature,” things will work out better. Generations of organic and natural-systems farmers have proven it and have created a multi-billion-dollar industry around it. Those of us who have been at this for a while have seen pest pressure decline. We’ve watched soil improve. We’ve seen systems begin to regulate themselves in ways that conventional agriculture will never believe or understand. 

I agree with McGuire that if we stop there — if we turn our observations into a dogmatically followed ideology — we miss the deeper, more complicated reality.

Nature is not static. It is not balanced in the way that a simplistic “pop ecology” would have us believe. Using the Bambi narrative again, it is a gross oversimplification to think that Man is a mean horrible hunter that only thinks of killing, and that Fire is only a destructive force unleashed by careless hunters. The truth is more complex than that. I agree with MacGuire that foisting a Bambi version of ecological agriculture on the public is misleading. Like nature itself, ecological agriculture isn’t that simple. It’s dynamic, pulsing, chaotic, and driven by disturbance. It could care less about your opinion of it and whether you use your opinions of it as propaganda. 

As ecological farmers, it is imperative that we view the ecological reality of our place as it actually is and not necessarily how we think it should be. We should be especially wary of viewing things how others tell us how it “actually is.” 

The Pulse We Step Into

If you could step far enough away from Earth, you actually would see “balance.” Not something harmonized and unchanging, but something in balance and in motion. You’d see a green wave of leaves emerging and rolling north every spring and then retreating again in the fall. Plants surge, insects follow, and predators follow them. There’s life, reproduction, death, and decay, the whole thing resets over and over again. 

Boom. Bust. Regenerate. Repeat. That’s the system we farm inside of. Our crops are not separate from nature. Our farms are part of that pulse. We feed the insects. The insects feed birds and bats and frogs and snakes, and then those same creatures recycle nutrients back into the system. Everything is connected. 

But here’s where things get uncomfortable, as McGuire rightly warns us: When we plant 1,000 acres of a single crop, we’re not stepping outside that system. We can’t. Our farms are merely amplifying a piece of it. We’re building an all-you-can-eat buffet for crop pests, with no bouncer.

The Pest Problem We Designed

When pests show up, it’s not because they’re “bad.” It’s because we made it easy for them. Plant a monoculture of broccoli or potatoes and you already know what’s coming. You’ve created ideal habitat with an unlimited food supply, and you’ve removed most of the natural checks and balances. You will have cabbage loopers and potato beetles, no matter how fertile your soil is!

From a population ecology standpoint, two rules apply that are relevant to us: 1) Every organism reproduces as fast as conditions allow. 2) Every population is controlled by something else: predation, disease, or competition. 

In a natural system, those controls are always present. In a monoculture, we’ve stripped them out. The pest doesn’t “invade” our field or crops — it responds to the conditions we’ve created for them. How we deal with them ecologically is what differentiates us from “pop ecologists.”

Three Ways Upstream

There are three ways to deal with the reality of pests. The first is the jet boat approach: massive horsepower, chemistry, control. Smash your way upstream. Spray, fertilize, correct, repeat. Fight the invasion with every tool at your disposal. It’s expensive, it’s toxic (I have two grandfathers who died from chemically caused cancers), and it’s becoming less and less effective as pest populations out-breed our ability to find new poisons. 

The second approach is the pop ecology approach: Stop spraying toxic chemicals, stop using chemical fertilizers, make a compost pile, let everything come into balance and live happily ever after with lots of flowers and butterflies. This is a walking-on-water daydream, and unfortunately quite a few people believe that it is that simple. 

The third approach is the kayak approach: Read the current and use the system’s own forces to move you upstream. Design your farm ecologically so that many of the problems don’t arise in the first place. Paddle fast here, but just steer over there. 

This approach is much harder. It requires more knowledge, more observation, more technical expertise, and more humility. It requires that you act at the right place and the right time and that you pay attention to actual reality, not some theory or Instagram thread. It’s this third way where the long-term resilience lives.

Here’s where the “pop ecology” critique is actually quite valid. Neither extreme works. We can’t just step aside and let nature run the farm for us, and we can’t dominate the system indefinitely with inputs, which have expensive and toxic consequences. The real work is in the middle. 

Acres U.S.A. eco-farmers collaborate with ecological processes. We seek to understand them and leverage them in order to stay successful and keep you fed. 

Soil: Biology Meets Arithmetic

Let’s talk about soil… Soil is built by the interaction of life (roots, microbes, fungi, other critters), life’s products (H⁺ ions, exudates, urine, manure, biomass, etc.), and the minerals of the parent material — the soil itself. This is where some of the inconvenience comes in for the Bambi version of pop ecology: When we harvest crops, we export nutrients. This is not philosophy. This is physically observable and mathematical. If we don’t replace those nutrients, soil fertility declines. 

So, what do we do? We stop pretending that this is a Bambi world, AND we stop pretending we can outsmart nature by just adding more chemicals to what can become nothing more than an outdoor hydroponic system. 

True ecological agriculture builds soil biologically through cover crops, perennials, and grazing. It recycles nutrients via manure, compost, deep-rooted plants, mulching, and chipping. And it replenishes minerals when needed with rock dusts, amendments, and even selective synthetics when appropriate (chemically derived methionine in certified organic poultry feed as an example). 

That’s not a compromise. That’s ecological realism. Healthy soil, healthy plants, healthy animals, and healthy humans aren’t just NPK, insecticides, herbicides, and fungicides. Healthy soil is a full mineral and biological system. Calcium for structure, trace minerals for enzyme systems, sulfur for proteins, biology to tie it all together. Get it right, and something interesting happens: pests stop being a crisis. They become feedback about how healthy your system actually is.

Biodiversity: Function Over Romance

There’s another trap in “pop ecology”: the idea that more diversity is always better. It’s not. A 12-species cover crop mix is not automatically superior to a well-designed two-species system. What matters is function — having the right organisms doing the right jobs in preparation for the next crops. 

I’ve been harassed multiple times because my cover crop system doesn’t have enough diversity to it. I use rye or wheat over the winter, a multi-clover blend top-seeded in late winter, and I hay or graze that for a year or two. Why don’t I have a 32-species mix? Because I don’t have to. My soil has been steadily improving for 30 years. Simple diversity works. 

Take oak trees, for example: Oaks support hundreds of insect species — more than any other plant in North America. Almost none of those insects eat your crops. Birds, bats and amphibians feast on those insects, as well as the pests when they show up in your crop. By adding this single species to your farm, you add at least some measure of pest control. That’s functional biodiversity. It’s not ideology. It’s not pop ecology — it’s pest-control infrastructure. 

The Real Spray Rig

If you want pest control, stop thinking about sprays. Start thinking about habitat. Your real pest control workforce isn’t in a jug. Healthy plants can tolerate some insect damage. Healthy soil grows healthy plants. Healthy soil grows healthy habitat for insect predators: predatory insects, birds, bats, tree frogs, toads, other amphibians, microbes. These are all real pest control, not some pop ecology myth. 

All of your predators need food. They all need shelter and a place to reproduce. All of them need connectivity so they can move from one place to another where they can ply their trade. That means:

• Continuous flowering strips for beneficial insects (terrace berms are perfect for this!) 
• Hedgerows and tree systems for birds (agroforestry brings these right into your field)
• Water sources for amphibians and dragonflies (pocket ponds, WASCOBs, etc.) 
• Undisturbed zones for overwintering predators (within tree-rows, field corners) 
• Structures for owls, bats, and raptors (trees, perches, posts) 

When those systems are in place, pest control becomes distributed, continuous and self-reinforcing. It is designed into your system. It doesn’t mean no pests, but it means less reliance on toxic, expensive inputs.

Nature Doesn’t Optimize for You

Pop ecology might not like this, but nature doesn’t care about your yield goals. It doesn’t care about your profit margins. It optimizes for survival, reproduction, and energy flow.

That means that soil builds slowly while pest populations can fluctuate wildly. Disturbance is constant yet unpredictable. Your “stable” agroforestry system might get leveled by an ice-storm, followed by eight inches of rain and hurricane-force winds. 

If we want reliable production, we have to work within those processes. We need to read their currents and paddle our kayak in the right direction at the right time. 

There are no perfect solutions in agriculture. Only tradeoffs:

• Higher yields will require more inputs. So, design many of those inputs into your system. 
• Simpler systems are easier to manage (corn on soy on corn on soy on …) but more fragile. 
• Diverse systems are resilient but complex. Agroforestry is a good example of how we can simply complex systems by design. 
• Faster short-term gains often come at a long-term cost.

The ecological farmer doesn’t deny this. We don’t live within a Bambi version of reality. We live in actual reality, and we work with it. 

Our job is to understand nature’s processes deeply enough to apply them today without illusion, without shortcuts, and without cute marketing or political slogans, because the real question isn’t “Does nature know best?” The real question is, “Do we understand nature well enough to work with it honestly, intelligently, and effectively in the real world of farming?”

That’s not pop ecology. That’s what we do.
