dw = Density of water taken as 1 There are two methods concerning when to irrigate. One method is based on the percentage of AWC within the root zone and the other is based on soil moisture tension. This difference in concept is shown in Figure FL2-2 which shows moisture release curves for three soils. In this figure moisture content is ...
