How do you plant a cover crop without tilling?

Cover crops are usually plowed down, but another option is flattening the cover crop to form a thick carpet, or mat. They do this with a roller-crimper—a heavy, rolling drum attached to a tractor. The farmer then uses a no-till planter to plant seeds into the flattened mat for the next season.

How long does cover crop take to decompose?

“Killing cover crops as late as feasible will maximize plant growth and residual nutrient accumulation,” she said. Stewart says, however, to be sure and allow at least two weeks for cover crops to decompose, release nutrients, and recharge soil moisture.
