- Mammoth Red is the best clover for deficient soils with a high nitrogen fixation ability and long tap root to loosen and distribute nutrients from deep in the soil.
Mammoth Red is the best clover for deficient soils. The plant is large with big leaves, making it an ideal grazing crop.

It does, like most clovers, perform poorly in hot weather unless seeded into a crop canopy.Read more about Cover Crops:
