Nitrogen-fixing cover crops are an essential component of building productive, healthy soils on the farm. Through biological nitrogen fixation leguminous cover crops provide growers with a non-manure source of plant available nutrients. Nitrogen-fixing cover crops also protect soil from erosion, contribute to organic matter formation, reduce weed pressure, and break recurring pest and disease cycles.
Your choice of cover crop species or mixtures will depend on your crop rotation, what time of year you are planting and the potential benefits you hope to gain.
