Legume species-specific bacteria form a symbiotic relationship with the legume roots. The resulting nodules contain the bacteria. These bacteria can biologically fix nitrogen (N) from the air, making it available to the plant.
Kansas no-tiller John Stigge believes cover crops can deliver in year one if growers utilize the ‘power of 3’ that includes legumes, brassicas and grasses.
Following harvest of winter wheat or other small grains, fields are often left fallow. But with more than 40% of the growing season remaining, planting a cover crop may be a good option, says University of Wisconsin Extension.
One expected benefit of using legumes as a cover crop is to provide a source of nitrogen (N) to the cropping system, but in certain situations the amount of fixed N may be lower than anticipated, says University of Nebraska Extension.
One of the Agricultural Research Service's more unusual germplasm collections is devoted to Rhizobium, bacteria that form symbiotic (mutually beneficial) relationships with soybeans, alfalfa, peanuts, beans, and other legumes to convert nitrogen gas from the air into fertilizer for the plants.
Dormant seedings succeed as long as your soil is relatively dry and soil temperature is too cold for seeds to germinate, says University of Nebraska Extension
