explain rainwater harvesting and drip irrigation
Answers
Rainwater-harvesting for irrigation has significant potential to increase crop production in the arid/dry areas by supplying harvested rainwater through drip irrigation, sprinkler system and many such. Rainwater harvesting for agriculture is defined as farming in dry regions by harvesting it.
Rainwater harvesting is the collection and storage of rain, rather than allowing it to run off. Rainwater is collected from a roof-like surface and redirected to a tank, cistern, deep pit, aquifer, or a reservoir with percolation. Dew and fog can also be collected with nets or other tools.
Drip irrigation is a type of micro-irrigation system that has the potential to save water and nutrients by allowing water to drip slowly to the roots of plants, either from above the soil surface or buried below the surface. The goal is to place water directly into the root zone and minimize evaporation.
