Short rotation forage crops function both as cover crops when they occupy land for pasture or haying, and as green manures when they are eventually incorporated or killed for the no-till mulch. Examples include sods of alfalfa, clover, and legumes. For maximum soil-improving benefits, the forage should not be grazed or cut for hay during its last growth period, to allow for biomass to accumulate prior to killing.
Sweet clover can grow nearly anywhere under most conditions. Our favorite clover because it is more versatile than other clovers at nitrogen fixating, erosion control and attracting beneficial insects.
