BayG.A.P. SERVICE PROGRAM MODULE 3 MODULE 3.1: IRRIGATION INFRASTRUCTURE Irrigation is the additional application of water to a field in dry areas or in periods of insufficient rainfall in order to increase crop yields. Irrigation must be optimized to achieve water sustainability. SUSTAINABLE USE OF WATER To avoid irrigation problems the first thing to bear in mind is that not only your crop needs to be watered. Most problems with irrigation appear when farmers exceed the proportion of water applied on their fields. Variables to control application and optimize the way water is used are, for example: Adaption of duration of the irrigation, rate of application, characteristics and absorption capacity of the soil, etc. How must water and irrigation be used? • The use of irrigation may increase the amount of production. • Identify the water sources used for irrigation and, with the assistance of the technician, verify that they are not contaminated. Remember! Sewage water should never be used for irrigation or as drinking water. • Always use the irrigation method recommended for your crop. • Regard the water requirements of the crop (do not irrigate excessively). • Incorrect use of water may damage the quality of the crop, hence it is necessary to program the use of irrigation. • For all these activities consult the technician of your trust. 3
