            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.
