Dan Perkins, Jasper County (Indiana) SWCD, put together a series of videos demonstrating the use of a high clearance sprayer to apply cover crops. You can watch those videos below. The last video is a Power Point presentation where Dan answers several questions he's been getting on the topic:
What are a couple types of high clearance sprayers available for cc seeding?
Are corn ears and stalks knocked down during seeding?
How much yield loss from end row turning?
Can we seed into soybeans?
