Proper selection, establishment and production of high-residue cover crops is the key to organic, no-till. An ideal cover crop is moderately priced, easily established, you must be able to establish it without difficulty; highly productive, which means, a lot of biomass or residues produced; easily killed mechanically, which of course is required by organics, and lastly, is not allelopathic to the cash crop. It’s fine to be allelopathic to the weeds, but it can’t be allelopathic or interfere with crop growth.
