WebStep 1: Determine the net and gross depth (d) in mm of the irrigation applications Table 5 shows that groundnuts have a medium root depth. Grown on a loamy soil, the net irrigation depth (d net) will thus be approximately 40 mm (Table 4). The gross irrigation depth (d gross) can be calculated using the following formula: Webwater (Sa) is depleted from the root depth, i.e. to replenish the depleted water. Therefore: Net depth of irrigation dose (d) (mm) = (Sa × p) D where Sa is the available water in millimetres per metre, p is the permissible depletion (fraction), and D is the root depth (m).
