- Good residue cover is essential for no-till. Cover crops should therefore be an integral part of no-till systems that would otherwise have low crop residue cover.
- Kill the cover crop at least 2 weeks before planting the main crop to avoid early moisture stress for the main crop as well as other problems.
- Plant into a standing cover crop. This will limit hair-pinning. You can shred or mow the cover crop after planting, although it is not necessary.
- Do not use a planter with a shoe seed opener when planting into cover crops. The shoe planter will drag cover crops all over the field. Use disk openers instead.
- Do not use fingered row cleaners in heavy cover crops. The cover crop will wrap around the fingered row cleaners, creating many problems. Either do not use row cleaners, or use disk row cleaners.
