How, much amount of available Nitrogen is added to soil after green manuring with Dhiancha (Sesbania sp.), where green manuring with dhiancha or organic cultivation has been practiced for 4 to 5 years?>
Rk Naresh
Dhaincha is the best green manure crop because it contains 3.50% N, which is higher than any other green manure crop. With green manure use, the amount of nitrogen that is available to the succeeding crop is usually in the range of 40-60% of the total amount of nitrogen that is contained within the green manure crop.

3. Prevailing climate
4. Nature of the soil
