Incorporation of perennial legumes and cover crops into our row cropping systems and reduction of tillage will reduce soil erosion and concurrent loss of phosphorous and nitrogen to the surface water. Kura clover (Trifolium ambiguum M. Bieb.) is a relatively new forage legume in North America that can be used in a living mulch system. It has an excellent forage yield and is persistent under a wide range of soil and climatic environments. Iowa Department of Agriculture and Land Stewardship, Integrated Farm/Livestock Management Demonstration Program, with the assistance of Iowa State University Extension, are currently funding a large on-farm demonstration project in northeast Iowa on educating growers about kura clover living mulch systems for grain crop production.
