The field capacity and permanent wilting point for a given 0.8 m root zone soil are 35% and 10% respectively. At a given time, the soil moisture in the soil is 20% when a farmer irrigates the soil with 250 mm depth of water. Assuming bulk specific gravity of the soil is 1.6, determine amount of water wasted from consideration of irrigation?( take the plan area of the soil in root zone to be 1 m2)
