BENEFITS :

Nitrogen Fixation: Sunhemp roots partner with soil bacteria (Rhizobium) to capture nitrogen from the air and fix up to 120–140 kg of nitrogen per hectare, feeding subsequent crops naturally. 

Green Manure: Tilling the green plant back into the soil before it flowers breaks down biomass rapidly, adding rich organic matter and boosting soil carbon. 

Weed and Pest Suppression: Its dense, rapid canopy smothers unwanted weeds, while root compounds act as bio-fumigants to suppress harmful root-knot nematodes. 

Moisture and Structure: Deep root systems break up compacted earth, improving water infiltration, soil aeration, and moisture retention during dry periods. 

Erosion Control: The thick growth protects topsoil from washing or blowing away during heavy rains or wind.
