A farmer collected a soil sample from his 4-hectare cornfield with root zone depth of 75 cm. The mass of the sample immediately after retrieval is 1010.5 grams and the mass after subsequent oven drying is 878.4 grams. Determine the (a) porosity of the soil, (b) available moisture for plant use when the sample was taken and (c) volume of water needed to irrigate the farm up to 30% by mass. Other data are the following:
