One weird trick to fix farms forever

As always I’m skeptical of silver bullets, but mimicing Mother Nature is not a silver bullet. It’s a complex interaction of diverse species and cycling nutrients the way the earth was made (or has evolved) to. It’s only a “weird trick” because we’ve done it the wrong way for so long.

“Our cover crops work together like a community – you have several people helping instead of one, and if one slows down, the others kind of pick it up,” he says. “We’re trying to mimic Mother Nature.” Cover crops have helped Brandt slash his use of synthetic fertilizers and herbicides. Half of his corn and soy crop is flourishing without any of either; the other half has gotten much lower applications of those pricey additives than what crop consultants around here recommend.

But Brandt’s not trying to go organic – he prefers the flexibility of being able to use conventional inputs in a pinch. He refuses, however, to compromise on one thing: tilling. Brandt never, ever tills his soil. Ripping the soil up with steel blades creates a nice, clean, weed-free bed for seeds, but it also disturbs soil microbiota and leaves dirt vulnerable to erosion. The promise of no-till, cover-crop farming is that it not only can reduce agrichemical use, but also help keep the heartland churning out food – even as extreme weather events like drought and floods become ever more common.
