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.

Happy Thanksgiving, Merry Christmas, and Happy New Year--that's a lot of stuff going on kind of lumped together.  Which brings me to my thought this month:  it's all related. Perhaps the signature difference between Polyface and current mainline food thinking is integration versus segregation.  I could use numerous words to describe this basic concept, like parts versus wholes, but I think these two are as good as any. Conventional industrial food systems break things apart.   We see it on farms that grow only one or two things, without regard for the greater inter-relatedness of ecology, all the way up to packaged and processed food.  Modern processed foods don't use whole ingredients; they use pieces of things.  They strip out the germ of the wheat, for example. They refine things to the point that the food bears no resemblance to its natural state.  Then they put all these pieces together and call it food.  But these pieces came from widely divergent places, and the beautiful unprocessed original no longer exists. When Dad and I were brainstorming what to call this farm venture that would eventually become Polyface, Dad's assumption was that we'd call it Salatin Inc.--you know, like Ford Motor Company or Chrysler (named for Walter P. Chrysler, the founder). I was adamant that it NOT be our family name for two reasons.   First, I suggested there may be a day when a Salatin isn't at the helm.  Secondly, I wanted the name to recognize integrated thinking. I came up with the name "Interface Inc." to recognize the three great environments:  water, land, and forest.   For 20 years, during what I call our experimental homesteading days, we'd been planting trees, fencing out riparian zones, fencing out the forest to protect it from cows, and developing a landscape plan with these various zones in mind.  The State Corporation Commission rejected the name because, unbeknownst to us, Virginia already had an "Interface Inc."  It was a labor arbitration company to work out disagreements between labor and management. I was milking the cow when Dad told me the bad news, and I spontaneously blurted:  "If we can't be Interface, let's be Polyface--the farm of many faces."  Dad laughed, but we both liked the idea, and it stuck and was approved. The point here is that from the outset, all our thinking was about how to leverage the various assets of the diversified ecosystem and then harness the distinctives of the various animals.   As a result, we looked at symbiotic natural patterns and have done our best to duplicate them.  The Eggmobile follows the cows so the chickens can scratch through cow pies.  We use pigs to aerate compost.  Our small flock of sheep is like a glorified weed eater, cleaning up fence lines and around farm buildings to reduce mowing. The animals move through the pastures, paddock to paddock; they don't stay in the same place. Illustrative of "conventional-think", Virginia Tech veterinary professors who judged my son Daniel's 4-H talk titled "Symbiosis and Synergy in the Racken (Rabbit-Chicken) House" at the state contest nearly 30 years ago couldn't restrain their skepticism.  "Aren't you concerned about diseases with two species that close to each other?" I was never so proud.  He was about 15 and, without batting an eye, looked those professors in the eye and replied:  "We've learned that most pathogens don't cross-speciate."   Folks, I had not prepped him for that question.  When he responded like that, those three professors slapped their legs and laughed at the audacious notion.  They had no further comments and immediately tried to recruit him to enroll at Virginia Tech and major in Veterinary Science. Instead, he stayed with me on the farm and scaled up these simple integrated relationships to the thousands of animals we have now--with virtually no vet bills.  Meanwhile, conventional experts wring their hands over bird flu, screw worm, African swine fever, blackleg, and a host of maladies that attack places where an integrated approach toward biology is severely lacking. Pediatrician Dr. Sharon Goldfield, director of population health for the Murdoch Children's Research Institute, wrote a fascinating op-ed in the Wall Street Journal last week titled "Baby Food and Youth Obesity."  She slammed "packaged baby and toddler foods" because they fail even rudimentary nutrition standards. Their surveys indicated that "80 percent of children are eating packaged toddler foods, many of which are ultra-processed, from an early age, with 43 percent of them eating these foods at least five days a week." Kids are eating out of boxes and slurping from concoctions created by a segregated mentality from field to stomach.  This segregated thinking even permeates parental decision making, divorcing overall health from food and assuming whatever happens, pharmaceuticals can fix it. At Polyface, everything we do assumes that everything we do affects something else we do.  It's that simple.   Both land health and people health occur when we realize everything relates to everything.  You can't just eat well and not exercise.  You can't dismiss the value of sunlight on your skin; especially early morning sunlight.  Hydration.  Sleep.  Stress.  Forgiveness.  Gratitude.  It's all part of us. As we celebrate all these holiday times and imagine the relatedness of Thanksgiving with the Christmas story with the eagerness of a new year, imagine all the things going on in your life and how they work together.  Or how if you pull them apart, things fray. Be assured that here at Polyface we're trying to integrate ecology, people, and economy in an overall symbiotic whole to deliver you the best food at a reasonable price.   And we thank you for helping us build an integrated whole that respects earthworms all the way to our dinner plate and microbiome.  We're not feeding you earthworms, but be assured they play an ongoing role in every bite you enjoy from Polyface.  Thank you.
