sweetclover production, sweetclover management, planting
Sweetclover was introduced into the United States from southeastern Asia in the early 1700s. As late as 1910 it was legislated against as a weed in some states. We now know that sweetclover is valuable for hay, silage, pasture, seed, soil improvement, and as a source of nectar and pollen for honey bees.
