Answer:
Explanation: Nitrogen-Phosphorus Fertilizers. Ammonium phosphates are produced by reacting ammonia with phosphoric acid or a mixture of phosphoric and either sulfuric or nitric acids. Ammonium phosphates are the leading nitrogen-phosphorus products in the fertilizer industry
the simplest level, the process of composting requires making a heap of wet organic matter (also called green waste), such as leaves, grass, and food scraps, and waiting for the materials to break down into humus after a period of months
.Biofertilizers are also called microbial inoculants and can be generally described as containing living microorganism of efficient strain for nitrogen fixing, solubilization and mobilization of P and K, increasing organic carbon, balanced carbon/nitrogen contents, promotion of plant growth through enhancing absorption ...
Fallow is a farming technique in which arable land is left without sowing for one or more vegetative cycles. The goal of fallowing is to allow the land to recover and store organic matter while retaining moisture and disrupting the lifecycles of pathogens by temporarily removing their hosts.Planting a leguminous plant will result in nitrogen-rich soil and when a cereal is grown in this soil there is increase in food grain production. Rotation of crops help in weed control and pest control. Mixed cropping is growing of two or more crops simultaneously on the same piece of land
