Agriculture aid projects using Yamaha water pumps in Senegal
Drip irrigation was developed in Israel in the 1960s. It is most suited for dry regions with a lack of water supply. The method allows maximum irrigation from limited water supplies. Water is passed through a purpose-built tube with holes placed along the crops, and fed one drip at a time to the crops.
The method of spraying water onto dry soil causes the water to dry and evaporate quickly. On the contrary, the gradual, drip-feeding process allows the crop to absorb the droplets as they fall. Using sprinklers to spray the crop can also cause both the water and fertilizer to sink deep into the soil. However, with drip irrigation, crops can efficiently absorb the nutrients contained in the fertilizer and the water. Drip irrigation applies water slowly and directly to the roots of crops through small pipes. It uses less water than sprinkler irrigation. Since water is applied directly to the root zone, evaporation and runoff are minimized and crops can absorb water and nutrients from soil.
