Frosty is an ideal nitrogen fixing cover crop because of its growth habit and timing. It produces early season biomass that makes it highly attractive as a cover crop in rotation with corn, cotton, and more
Nitrogen Fixation Ability to fix nitrogen into your soil for your subsequent cash crops to utilize as fertilizer for growth and energy  
Weed Suppression Ability to suppress weeds by shading soil and releasing allelopathic chemicals  
Beneficial Insectary Ability to attract beneficial insects and reduce your reliance on costly insecticides  
Forage Quality Ability to improve forage quality by suppressing weeds and providing highly nutritious forage  
Nutrient Recycling Ability to store excess nutrients from cash crops for use in subsequent plantings  
Quick Regrowth Ability to increase soil organic matter by accumulating biomass in a short period of time  
Soil Compaction Ability to increase nutrient uptake and root development by breaking up dense and compacted soil  
Erosion Control Ability to hold soil in place to capture and retain moisture from rainfall and prevent topsoil erosion  
Water Management Ability to increase field productivity by improving the drainage of wet soils  
Nematode Resistance Ability to suppress the growth of nematodes by interrupting their reproductive cycles

Improve your soil and increase your yields with nitrogen-fixing cover crops from a leader in forage, turf, and cover crop research.


Frosty isn’t just cold tolerant, with good management, berseem clover is moderately tolerant to salt and saturated soils low in pH.
Heat Ability to tolerate heat stress caused by warm temperatures and/or limited water availability  
Drought Ability to tolerate periods of limited water availability  
Sub-Freezing Ability to tolerate freezing temperatures for an extended period of time  
Shade Ability to tolerate low light conditions caused by plant competition  
Flood Ability to tolerate standing water or flooded areas for a limited period of time  
Low Fertility Ability to tolerate soils with limited nitrogen, and other mineral resources necessary for growth  


All species of livestock and poultry will take readily to berseem forage. Research has shown that by adding Frosty to your initial sowing of alfalfa (10-20% of the mix) that the synergy between the two results in greater forage yields and improved forage quality.

Frosty emerges quickly from the ground making it ideal for hunters looking for a clover to hunt over. With adequate moisture, Frosty will be drawing in deer as quick as 45 days after planting.

When we cut the CC mix in early October, the Frosty was over waist high and growing profusely. The cattle intake on the grazed cover crop was outstanding. I was able to graze the cover crop mix twice.

Recent studies have shown that an 80/20 alfalfa/berseem clover mix could increase yield, crude protein, and water soluble carbohydrate levels in hay fields. When overseeded into declining or winterkilled stands of alfalfa.
