PRINCIPLE OF DRIP IRRIGATION<br />

• Drip irrigation <strong>in</strong>volves dripp<strong>in</strong>g water onto the soil at very low flow rates<br />

from a system <strong>of</strong> small-diameter plastic pipes fitted with outlets (drip<br />

emitters).<br />

• The basic concept underly<strong>in</strong>g the drip irrigation method is to supply the<br />

amount <strong>of</strong> water needed by the plant with<strong>in</strong> a limited volume <strong>of</strong> soil and as<br />

<strong>of</strong>ten as needed. Water is applied directly at the plant root zone.<br />

• The volume <strong>of</strong> soil irrigated by each drip emitter and the water flow along<br />

the soil pr<strong>of</strong>ile is a function <strong>of</strong> the characteristics <strong>of</strong> the soil (texture and<br />

hydraulic conductivity) and the discharge rate <strong>of</strong> the drip emitter.<br />

• Applications are usually as frequent as daily to provide a favorable moisture<br />

level for the plants to flourish.<br />
