Interseeding Webinar – Seeding Annual Ryegrass and other Cover Crops in the Spring

This spring, the University of Pennsylvania conduced a webinar on the subject of interseeding.

As you may have read here in past blog posts, interseeding is done in the late spring, when corn and beans are sufficiently established (v 6 in corn) to plant annual ryegrass or another cover crop between the corn or bean rows. This planting is done with customized equipment – often a sprayer retrofitted with an air seeder. Some are combining this seeding effort with a side dress of nitrogen, to give the cover crop and the corn some boost.

Interseeding has the benefits of being planted when there’s more time…trying to plant in the fall, around harvest, is often complicated with the harvest itself and sometimes weather. Interseeding has the added benefit of establishing a cover crop in the spring – which then goes semi dormant in the shade of summer foliage – and then its being able to get a good growth spurt in the fall after harvest. The early establishment of the cover crop thus increases the chances for the crop to survive the winter. It also acts as an effective weed suppressor.
