Effective Precipitation,tural precipitation. Hence, precipitation needs to be measured (Fig. 3.1). Not all precipitation infiltrates into the soil; a part may evaporate; another part may become surface runoff. Of the precipitation that infiltrates, only a part will be stored in the root zone and the remainder will recharge

Capillary Rise,. This chapter illustrates the case of when capillary rise is a potential source of water. In which case, the calculated crop water requirements should be corrected for the contribution from groundwater (see Section 4.6)
