DECATUR, IND. — Mike Werling shoulders his way into a field of head-high corn and peers down a row.

“That’s a beautiful sight!” he exclaims.

It was not the corn that delighted Mr. Werling in late September as much as what was growing underneath. Shoots of rapeseed and rye poked up through the dirt, spreading a green flush beneath the tangled leaves. The new plants, sown the week before into the ripe corn, will remain in the field long after the harvest. They’ll protect the soil over the winter and absorb nutrients that might otherwise find their way into the St. Marys River, whose brown-green waters flow past Werling’s farm on their way to Lake Erie.
