DRIP IRRIGATION
COMPULSORY FOR HOME.
Drip irrigation involves dripping water onto the soil at very low rates (2-20 litres/hour) from a system of Drip diameter plastic pipes fitted with outlets called emiters. Water is applied close to plants so that only part of the soil in which the roots grow is wetted, unlike surface and sprinkler irrigation, which involves e whole soil. With drip irrigation water, applications are more frequent (usually every 1-3 days) an with other methods and this provides a very favourable high moisture level in the soil in which plants an flourish. Drip irrigation is most suitable for row crops (vegetables, soft fruit), and tree and vine orchards where one r more emitters can be provided for each plant.
Generally only high
value crops are considered because of e high capital costs of installing a drip
system Normally the crop would be planted along contour lines and the water
supply pipes would be laid along e contour also. Drip irrigation is suitable
for most soils. On clay soils water must be applied slowly to avoid face water
ponding and runoff. On sandy soils higher emitter discharge rates will be
needed to ensure r fall a pair face water quate lateral wetting of the soil
One of the main problems with drip irrigation is blockage of the emitters.
All
emiters have very small ways ranging from 0.2-2.0 mm in diameter and these can become blocked if the
water is not clean. Thus s essential for irrigation water to be free of
sediments. If this is not so, then filtration of the irrigation water ll be
needed. How it works: i he pump unit takes water from the source and proof

The control head consists of valves to control the discharge and pressure in the entire system. Some trol head units contain a filter and fertilizer or nutrient tank. These slowly add a measured dose of tilizer into the water during irrigation. This is one of the major advantages of drip irrigation over other methods Mainlines, submain and laterals supply water from the control head into the fields.
