I'm going to spin on 100 lbs AMS and 70 lbs of urea on standing corn soon. Corn plants are 18- 24 inches tall. If I add cover crop mix to fert will the seed lay there until corn starts to die ? I was thinking maybe some legumes and radish now, then spin on rye after harvest. Any thoughts or suggestions ? Corn usually comes off to late to do this in the fall . Northern Maryland.
