9.In irrigation , which technique reduces the water loss?
a-Evaporation
Various techniques have been tried to reduce losses of irrigation water. Two major sources of loss, particularly from surface supplies and surface systems, are evaporation and seepage from reservoirs and canals. Many studies have been made of techniques to suppress evaporation.
a)Drip irrigation
a-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.
b) Canal Irrigation
a-b) Canal irrigation
Irrigation canals are the main waterways that bring irrigation water from a water source to the areas to be irrigated. ... An open canal, channel, or ditch, is an open waterway whose purpose is to carry water from one place to another. Channels and canals refer to main waterways supplying water to one or more farms.Nov 14, 2017
