Tesdell explained that when his European ancestors settled in the Midwest, they plowed the prairie and switched from deeply rooted perennial plants to shallow-rooted annual crops like wheat, oats, and corn instead. This “leaky system” refers to what is not absorbed by the crops on the field, most dangerously, in this case, fertilizer. “It’s
He would let the cover crop grow and overwinter and then plow down the following spring for green manure. Periodic mowing keeps it under control and adds a green manure mulch to the crops. Instead, I can terminate my winter cover and lightly plow it in this spring, put out my transplants, and undersow white clover.
This means increased crop yields and reduced inputs like fertilizers and pesticides. Cost savings : Regenerative farming often reduces the need for expensive inputs like synthetic fertilizers and pesticides. By building fertile, self-sustaining soil, farmers can cut costs significantly.
He was paid to plant it by the Olmsted County Groundwater Protection and Soil Health Program , a local effort that seeks to reduce overall fertilizer use by building soil—therefore cutting down on the nutrients that enter waterways—while helping farmers save money.

Better manure management is among the climate-smart practices the USDA is funding in the partnerships. 28, 2019. “But
Diesel-powered tractors replaced horse-powered plows, and synthetic nitrogen fertilizers replaced their manure. In the years after World War II, U.S. farms in the upper Midwest underwent an industrial revolution. The result was an orgy of overproduction. Vast gluts of corn and soybeans began to pile up, and prices plunged.
