6. The soil moisture at field capacity is 30% (dry-mass or weight basis) and at wilting point it is 12%. Allow 4 of the total available moisture to be retained in the soil before applying irrigation water. For a 1-m soil depth to be wetted and having 1.4 g/cm³ bulk density compute the: a) soil moisture content at the time of irrigation b) ha-cm/ha of water needed to bring the soil moisture back to field capacity. c) amount of water (in cm) in the soil at field capacity, d) amount of water (in cm) in the soil at the time of irrigation, e) amount of water (in cm) in the soil at wilting point.
