Alsike clover is an intermediate clover that is often used for hay, pasture, and soil improvement. It is a preferred choice on wetter and more acidic soils.
Sweet clover has a determinate taproot, reaching depths of up to 1 foot, with the ability to affix over 100 lbs. of actual nitrogen. Sweet clover is the most drought tolerant of forage legumes. It is also quite winter hardy and can extract and then release phosphorus, potassium and other micronutrients that are otherwise unavailable to crops. Sweet clover loosens soil structure, creates organic matter, and produces better soil tilth.

With its rapid, robust growth, crimson provides early spring nitrogen for full-season crops. Good nitrogen fixation makes crimson an excellent break crop for continuous corn producers.

Berseem Clover is a fast-growing summer annual. Berseem provides a high-quality forage that doesn’t cause bloat and works well with alfalfa. It is a heavy N producer and is among the least winter tolerant of true annual clovers. It also has an active root system and abundant biomass, making it an ideal winterkilled cover crop before corn or other high nitrogen demanding crops.
