Feeding the World

By far the most common question people ask me is, "Can the Polyface approach feed the world?"  

Yet another big op-ed piece in the New York Times on Sept 28 took this position to marginalize non-chemical agriculture, using the oft-quoted idea that we would need three times as much farmland to produce the food the world needs if we quit using glyphosate and chemical fertilizer.

Let's take a walk into history and see where this kind of "scientific studies show" originated.  

When Mason Carbaugh was Virginia Agriculture Commissioner more than 30 years ago, he issued a "state of the Commonwealth's Agriculture" each year.  I'll never forget opening it and reading his dire predictions about what would happen if we went to organic farming.  Half the world would starve; organic farmers needed to pick which half they wanted to starve.

This was long before the government organic certification program, but the rumblings toward non-chemical approaches were already rattling the establishment narrative.  They had to nip this rebellious notion in the bud.

I didn't cotton to being called a starvation advocate.  

Do you know how it makes you feel to be told your methodology would kill half the planet?  Think on that for a bit.  I began sleuthing the studies the commissioner cited to come to his conclusions.  Here is the pinnacle of scientific modeling at Virginia Tech, Virginia's esteemed land grant university.

They decided to do a comparison of chemical versus organic production.  The college had many test plots for studying things.  These were all fairly small 10 ft. X 12 ft. type plots.  Imagine a couple of football fields partitioned off into little plots to study pesticides, herbicides, various chemical concoctions, seed germination, and plant varieties.

In other words, these plots, for years, received all sorts of chemical cocktails along with tillage, herbicides--you get the picture.  The soil was dead.  The plots were certainly not part of a larger ecologically functional system.  These plots epitomized a linear reductionist segregated mechanistic paradigm toward biology.

Scientists identified a handful of plots to grow conventional chemical corn and an adjacent handful to grow the same hybrid corn organically.  The chemical plots received the full complement of fertilizer, pesticides, and herbicides.  The organic plots received nothing.  No compost.  No foliar fish emulsion.  And the corn was the same hybrids bred for chemical uptake, not open-pollinated varieties known for resilience in low-input systems.

You can imagine the outcome.  

The chemical plots grew beautifully and yielded bumper crop equivalents.  

The organic plots were weedy, poorly formed, and yielded a fraction of the others.  

Based on this "sound science" the university and agriculture writers like our current friend at the New York Times have disparaged non-chemical agriculture with credentialed authority.  

These types of studies were repeated at other land grant universities throughout the 1980s as the nascent organic food movement gained traction.

Anyone who knows a scintilla about non-chemical agriculture understands that biological soil is part of a larger system.  The soil is a living community of some 4.5 billion organisms per handful.  Today, only 10 percent of them are named.  The rest are unnamed and we don't even know what they do.  We're still that ignorant about soil.

Interestingly, in just the last couple of years, agronomists who appreciate this living community have identified something called a quorum.  

Until now, agronomists thought all the microorganisms in the soil competed with each other.  After all, a cursory look at nature seems to validate the notion of competition.  Pigs compete for the trough.  Cows compete for clover.  Chickens compete for grasshoppers.

But what we're now learning is that when the soil comes into balance, the various microscopic beings form a synergistic quorum and begin helping each other.  

They become complementary rather than competitive.  This enables each one, with its distinct advantage, to leverage it for the good of the whole.  The organisms begin helping each other, supplying shortages more easily when each becomes freed to pursue its distinct desire.  We see this in tree groups, fungal communities, and other things.

Even a herd of cows becomes like this when it gets large enough.  The herd protects itself from predators when it's healthy and balanced. Healthy animals seek companionship.

The point is that the grow-plots used for organic growing had no special attention and had been abused by chemicals for decades.  

Nothing could be farther from a healthy biological soil system.  

When Polyface begins managing another property, we generally don't see measurable soil changes until the third year.  It takes that long for the biological soil community to realize there's a new sheriff in town; one that loves them and wants to nurture and not nuke these precious micro-organisms.

The biological clock runs on its own schedule.  It's not a wheel bearing that you replace.  It's not a flat tire you fix.  It's a host of interconnected and amazingly complex relationships that heal one at a time.  

The scientists who concocted these supposedly objective growth studies cared not a fig about soil biology and the mysterious majesty of creation.

As the organic movement began, these were the kinds of studies used by the chemical crowd to demean and disparage the threatening notion that we could feed ourselves without poisons.  Naysayers still use these studies to vilify compost and extol the virtue of chemicals.  

Alas and alack, nothing becomes more believable than a lie repeated often enough and long enough, even though we can now see these studies for what they really are.

The truth is that biological systems--truly balanced, nurtured, and respected--spin circles around chemical systems.  Not just in raw production, but especially in nutrition.  

Nearly two decades ago, Polyface participated in a pastured egg study; our eggs averaged 1,038 micrograms of folic acid per egg; the USDA nutrition label says 48.  This is not the same food. Nutritional differences are in multiples. 

All you need to know is this:  500 years ago, North America produced more food than it does today.  

To be sure, it wasn't all eaten by humans.  Some 2 million wolves ate 20 pounds of meat a day.  Some 200 million beavers ate more vegetation (vegetables) than all the people today.  Flocks of birds (especially passenger pigeons) blocked out the sun for 48 hours.  And a herd of 100 million bison roamed the prairies. 

If we really want to feed the planet, we'd better be studying these ancient patterns and figuring out how to duplicate them on our domestic commercial farms.  

Decomposing carbon builds soil, not 10-10-10 chemical fertilizer.  

Grass and forbs build soil faster than trees.  Ponds provide the key to landscape hydration.  

Polyface is devoted to these protocols from nature; thank you for being a part of the restoration.

Food Shortages

I'm in Oregon today speaking at the Azure Harvest Festival and a question from the audience during a Q&A stimulated a lot of discussion:  "What do you think about the possibility and preparation surrounding food shortages?" David Stelzer, founder of Azure Standard, answered that the issue is not food volume, it's food nutrition.   That was an interesting answer that has a lot of merit.  As a nation, we are overfed and undernourished.  This is the crux of the MAHA movement and the epidemic diseases we see in our country. At Polyface, we know the pastured meat and poultry we produce is far superior in essential phytochemicals and other nutrients due to the carotenes, exercise, and stress-free habitat we offer.  You can taste the difference, feel the difference in texture, and measure it empirically. Perhaps my most poignant affirmation was our cat test.   We purchased meat from the supermarket and offered our own for the four cats.  They wouldn't touch the conventional meat (ground beef). Even though two plates and four cats would be much easier to accommodate if they spread out, all four crowded around the plate with our meat, eating it all and licking it up, before later sniffing and gingerly eating the supermarket counterpart. Since cats don't understand TV ads or USDA propaganda, they know what's good and what's not.   We encourage anyone dismissive of food differences to ask their pets:  you can trust them far more than doctors and experts. Yes, I get the nutrient deficiency angle on the shortage question.  But I'd like to explore it a bit further.   Right now, the world throws away more human-edible food, as a percentage of production, than at any time in human history.  The planet is awash in food.   Some 40 percent gets thrown away because it has a slight blemish, exceeds the sell-by date, or is tainted in some way.  We have a fundamentally segregated food supply rather than an integrated one, and that creates a lot of unusable waste. The vulnerabilities of our food system, I think, are much more subtle.  When I was in Uruguay two years ago, speaking at a conference, one of the other presenters was from Germany and showed a soil map of the globe.  Not a single commercial agricultural region had a stable or positive soil trajectory.  Every single area on the planet is losing soil; some faster than others, but globally our soil depletion continues without any sign of abatement. This is not a good trajectory.   As much as the technocrats promise food without soil, that's not the way to bet.  Soil is the skin of the earth.  When it goes, famine results.   The main difference now compared to centuries ago is that we have the capacity to move food around.   Nobody starves due to a lack of food on the planet; they starve due to socio-political unrest and dysfunction. But what happens when massive areas can't grow anything anymore?  Even being able to move food around doesn't help when there isn't enough.   The soil trajectory does not look good.  But at Polyface, we're building soil.  Areas covered with shale (layered rocks) half a century ago now have a foot of soil on them.  That's not the 3-5 feet that 150 years of inappropriate tillage eroded, but it's a build-back start. In addition to soil loss, as a planet we're seeing hydrologic decreases.   The Oglala aquifer, which undergirds the irrigated agriculture in five states, has dropped more than 100 feet in the last half-century.  At its current rate, it will be unpumpable in about 50 more years.  Imagine if all those circular irrigation pivots in Nebraska and Kansas shut down.  What then? At Polyface, we keep building ponds to inventory surface runoff.  By definition, surface runoff occurs when rains come too fast at once or too much at one time for the soil to absorb it.  Holding that and using it strategically in a drought is a way to reduce flooding during rain events and grow grass when it gets dry.  This is one of the most landscape resilient techniques we can implement. Finally, major animal and plant diseases threaten the world's food systems like never before.   African swine fever, hoof and mouth disease in cattle, and bird flu in poultry appear to be getting worse and covering larger areas.  Why?  We believe it's because chemicals and factory farming compromise the immunological systems in both plants and animals.  Monocrops and chemical fertilizers wreak havoc on immune systems, opening the planet's food systems to new levels of fragility. In contrast, at Polyface, we believe happy animals and biodiversity offer the best antidote to immunological deficiency.  Stress from unsanitary conditions, mono-species density, or dietary deficiency (rations or fertilizer) invites disease.  Nature uses disease to cull the weak.  Predators pick off the stragglers.  This is the way biology works. But at Polyface, we keep these vulnerabilities at bay with compost fertilization, pasture rotations, and lots of species diversity, including pollinators and wildlife. Here's the point:  the basic long-term vulnerabilities in the planet's food systems could all be reversed with practices Polyface uses every day.  Looked at another way, the entire food shortage question could be answered if eaters and farmers implemented these ecological and immunological protocols, working together to rather than completely separated.  We don't need to fall into an abyss of starvation. If we all simply began eating food from farms that build soil, increase water, and stimulate immunity, we could deliver a hospitable, abundant planet to our children.   Reversing these trajectories wouldn't take much time or money.  It takes intentionally-minded folks who connect the chain of sustenance from their plate to the planet. Polyface patrons do that.  Thank you.  Let's heal the land together. Joel
