A soil has a field capacity of 26% and the permanent wilting point of 7%.

Determine the water storage capacity of the soil if the depth of root zone is 0.7m, Assume dry unit weight of soil as 14KN/m3. Also determine the water depth required to be applied, If irrigation water applied when moisture content of the soil decreases to 12%, taking a water application efficiency as 80%.
