water requirements during the irrigation season. The amount of rainwater retained in the root zone is called effective rainfall (Pe) and should be deducted from the total irrigation water requirements calculated. It can be roughly estimated as: Pe = 0.8 P where P > 75 mm/month; Pe = 0.6 P where P < 75 mm/month. Pressurized Irrigation Techniques 6.5
