In soil, organic matter consists of plant and animal material that is in the process of decomposing. When it has fully decomposed it is called humus. Soil organic matter serves as a reservoir of nutrients for crops, provides soil aggregation, increases nutrient exchange, retains moisture, reduces compaction,... 

This humus is important for soil structure because it holds individual mineral particles together in clusters.

The major objective of the PMKSY is to achieve

•convergence of investments in irrigation at the field level,

•expand cultivable area under assured irrigation (Har Khet ko pani),

•improve on-farm water use efficiency to reduce wastage of water,

•enhance the adoption of precision-irrigation and other water saving technologies (More crop per drop),

•enhance recharge of aquifers and introduce sustainable water conservation practices by exploring the feasibility of reusing treated municipal based water for peri-urban agriculture and attract greater private investment in precision irrigation system.
