Drip Irrigation

2 Feb

The bushes in this picture are being irrigated using the drip irrigation method, which is the most common type of "microirrigation." If you look closely you’ll see the small horizontal pipes that are slowly dripping water running just above the ground. Drip irrigation is one of the more advanced techniques being used today because, for certain crops, it is much more efficient than traditional spray irrigation, where a larger portion of the water is lost to evaporation.

In drip irrigation, water is run through pipes (with holes in them) either buried or lying slightly above the ground next to the crops. Water slowly drips onto the crop roots and stems. Unlike spray irrigation, very little is lost to evaporation and the water can be directed only to the plants that need it, cutting back on water waste.

Advantages of microirrigation

Microirrigation has gained attention during recent years because of its potential to increase yields and decrease water, fertilizer, and labor requirements if managed properly. Microirrigation systems can apply water and fertilizer directly to individual plants or trees, reducing the wetted area by wetting only a fraction of the soil surface; thus, water is applied directly to the root zone.

  • Microirrigation is a low pressure, low volume irrigation system suitable for high-return value Crops such as fruit and vegetable Crops.
  • If managed properly, microirrigation can increase yields and decrease water, fertilizer and labor requirements.
  • Microirrigation applies the water only to the plant’s root zone and saves water because of the high application efficiency and high water distribution uniformity.
  • Microirrigation can irrigate sloping or irregularly-shaped land areas that cannot be flood irrigated.
  • Any water-soluble fertilizer may be injected through a microirrigation system.
