Corn School: Goin’ Crazy For Cover Crops

In this episode of the Corn School, Real Agriculture resident agronomist Peter Johnson goes cover crop crazy.

Standing in a residue-covered cornfield, Johnson sounds off on growers who insist on chopping corn stalks: “What a labour intensive, fuel expensive, ridiculous thing to do – it makes no sense whatsoever.”

What makes better sense for growers, says Johnson, is planting cover crops in corn. He notes that over the course of his career, researchers have evaluated the benefits of cover crops at least three times and he still wonders if they will actually work.
