Problem
A certain crop is planted in a 0.5 ha field. The soil's initial moisture content on the 2nd of March is 22%, field capacity is 25%, and the permanent wilting point is 15%, all by volume basis. Allowable moisture depletion is set at 40% and the rooting depth is 600 mm. Perform irrigation and drainage scheduling. Determine the volume of water required in case irrigation is needed. Complete the table and show your solution.
