Description

Leguminous crops, in particular, are excellent sources of green manures for enhancing soil fertility. Green manures have a positive impact on soil's microbiological, chemical, and physical characteristics. Green manures are known for their ability to deliver nitrogen in particular. The goal of this chapter is to illustrate the value of using agricultural leftovers and green manure as soil fertility management techniques. Finally, we illustrate the possible nutritional supply of agricultural residues from the primary crops cultivated in the tropics using a few instances. Also mentioned are the challenges and restrictions involved. The difficulties and limitations involved are also discussed. Long term work to evaluate the effects of contrasting fertility to building strategies in organic field vegetable systems. It has also been involved with an international project to develop a computer model which will help with planning rotations that include green manures. In a cropping system, the addition of proper green manuring crops can minimise the need for fertiliser on succeeding crops, boost nutrient uptake, and ultimately lead to greater crop development and yields.
