5 Steps Before Aerial Seeding Cover Crops
Cover crop planting season is coming for the northern Cornbelt! Many farmers are gearing up to aerial seed cover crops but how can we make sure we have green fields in the fall during harvest?
Take some hints from cover cropper Nathan Anderson who farms near Cherokee. In Nathan’s part of the state, sufficient rainfall is critical to aerial seeding cover crops. “What we don’t want is overseeding cover crops into a thick, dark corn canopy. We need more sunlight on the canopy floor followed by a good rain to achieve successful cover crop establishment. Don’t get started too soon.”
Steps for aerial seeding cover crops:
- Check when your corn is predicted to reach black layer. University of Missouri has a handy calculator to help you. Try to overseed within a couple days through Mid-September. For soybeans overseed when you see first yellow leaves.
- Is your seed secured? Did you contact your pilot and your fields have been outlined? Use Practical Farmers cover crop business directory to find seed and seeding services.
- Is rainfall predicted? Timely and sufficient rainfall is critical. Farmers observe that at least 1/2″ rainfall is needed followed by another storm to get the seed germinated and established,
- An on time harvest is the last component for success. Getting the crop off helps the cover crop grow.
- Have time to drill the crop following grain harvest? A drilled cover crop will almost always be more consistent than an aerial seeded cover crop but many times we are short on labor and time during harvest to be able to chase the combine with a drill full of cover crop seed. If the above steps are taken aerial seeding cover crops can result in successful establishment.
