  • DRIP IRRIGATIONBY:APRAJAY MINOCHA
  • What is Drip Irrigation?• Drip-irrigation, also known as micro-irrigation or trickle-irrigation is a remarkable water technology developeddecades ago.• Drip irrigation is the targeted, intelligent application ofwater, fertilizer, and chemicals that when used properlycan provide great benefits• Today it is commonly used all over the world inagricultural, nursery, greenhouse, landscape and avariety of industrial applications.
  • What is Drip Irrigation?• Drip irrigation allows for targeted water applications,where runoff, leaching and wetting of non-targeted areasis avoided or completely eliminated• In drip irrigation, water is applied near the plant rootthrough emitters or drippers, on or below the soilsurface, at a low rate varying from 2 - 20 lit res per hour• The soil moisture is kept at an optimum level withfrequent irrigations• Drip irrigation results in a very high water applicationefficiency of about 90-95 %
  • History of Drip Irrigation• The use of drip irrigation can be traced back to the ancientcustom in certain parts of India of irrigating a tulsi plant kept inthe courtyard• The drip system was developed for field crops in Israel in theearly 1960s and in Australia and North America in the late1960s
  • Advantages of Drip Irrigation• Increased revenue from increased yields• Increased revenue from increased quality• Decreased water costs• Decreased labor costs• Decreased energy costs• Decreased fertilizer costs• Decreased pesticide costs• Improved environmental quality
  • Conserving Water with DripIrrigation• Drip irrigation application uniformity is very high, usuallyover 90%• Unlike sprinklers, drip irrigation applies water directly tothe soil, eliminating water loss from wind.• Application rates are low so water may be spoon fed tothe crop or plant root zone in the exact amounts required(even on a daily or hourly basis).• Low application rates are less likely to run off fromheavier soils or sloping terrain.• Drip irrigation does not water non-targeted areas, suchas furrows and roads, in agriculture applications. Ingreenhouse applications, drip irrigation does not waterbetween beds, blocks, or benches
  • Conserving Water with DripIrrigation• Drip irrigation easily adapts to odd-shapedplanting areas which are difficult to addresswith sprinklers or gravity irrigation• Drip irrigation is capable of germinatingseeds and setting transplants whicheliminates the need for “sprinklering up” andeliminates the resulting waste in the earlystages of crop growth
