Cover Crops

Cover crop seed was adopted in the upper Midwest in the last five years to help growers utilize an environmentally sustainable management practice. in 2013 Asmus Farm Supply and Millborn Seeds partnered together to give customers this option.

Cover crops have shown the ability to bring positive attributes to standard crop rotation and we offer a variety of blends that can benefit your operation. For more unique situations, custom blends can be made.


Cover Crop FAQ

When can I graze it?
You can graze a cover crop anytime. However, the more growth you can obtain will result in more grazing days. If there is Sorghum hybrids in the mix, allow for 7 days after a frost event before you graze it.
How do I plant it?
Cover crops can be drilled or broadcasted. Just remember to plant the small seeds shallow and the large seeds deep.
When should I plant it?
Plant as soon as conditions allow. As the days get shorter, it becomes crucial to have it growing as soon as possible.
How do I set my drill?
Calibrate your drill using the drill’s directions. For a mix, look at your seed tag. Find the species that is the largest percentage by weight in the mix. Since your drill calibration guide likely won’t list that species, find a seed that is very similar in size and density. On your seed label, the suggested seeding rate (pounds/acre) is listed in the upper right corner. Remember, if there are many smaller, heavier seeds in the mix, it will flow faster than your calibrated setting, and you’ll have to slow the seed flow. This may not be perfect, but it’s a great place to start the calibration process. Monitor actual seed usage to fine tune your drill setting.
