Annual Clovers


Clovers are an excellent source of nitrogen and can double as a quality forage. They are good as a soil builder, as a weed suppressor and for erosion control. Clovers can be frost seeded and work well mixed with other cover crops such as small grains, grasses, radishes, and other legumes.

Clovers can be spring planted by frost seeding or planting with small grains. Use the grass seeding box on the drill.

Clovers can be overseeded into standing corn at last cultivation. Allow 6 to 7 weeks after the application of pre-emergent herbicides like Atrazine. Check the herbicide labels.

Clovers can be broadcast or aerial seeded into beans at leaf yellowing prior to leaf drop.

Red clover will grow well in cooler, moist conditions and will slow down over the summer months. Yellow blossom sweet clover does well in the summer and has the greatest warm weather biomass production of any legume, exceeding even alfalfa.

Berseem (also known as Egyptian clover) is very fast to establish and produces a huge amount of dry matter. It works well doubling as a cover crop and as a forage, producing 18-28% protein.
