Description: The concept of trickling or dripping as a method of irrigating crops has become a common practice in commercial agricultural production in recent years. In general, trickle/drip irrigation is being used on orchards, vegetable and small fruit crops, vineyards and nurseries. Trickle systems can apply water directly into the root zone in small quantities and with high frequency. Losses by run-off and deep percolation maybe minimized and water logging can be avoided. Trickle irrigation often increases crop yields and results in higher economic returns because of the high irrigation efficiency and low labor cost. Another potential advantage of this precisely controllable water delivery system is its use for the application of agricultural chemicals, such as plant nutrients and/or pesticides. Desired chemicals may be applied directly and only to the soil surface near the base of the plant. Effective results may be realized with considerable reduced quantities of chemicals. Soil-water pollution caused by irrigation and the residual effect of applied chemicals may then be minimized.
