drip irrigation
DRIP IRRIGATION
  • In Drip Irrigation, the plant foliage remains dry . This prevents the diseases and leaf burns that are some times evident in sprinkler Irrigation.
  • In Drip Irrigation, the area between wetted strips is kept dry. This facilitates the movement of machinery and farm implements when irrigation is in progress.
  • Drip Irrigation is well suited to all soils and also for heavy soils with low infiltration rate or soils that from surface crusts when sprinkled.
  • Drip Irrigation requires no special land preparation.

DRIP IRRIGATION
  • Drip Irrigation can not be used for frost protection or for cooling during period of hot weather like sprinkler irrigation.
  • Like sprinkler irrigation, Drip Irrigation can not be used or suitable for supplemental irrigation of large areas.
  • In dry , windy regions, Drip Irrigation of young tree plants in “light” soils encourages soil erosion due to the very limited wetted area. Strong winds also presents problems of anchorage.
