1.1 Climate- soil- water- crop (CSWC) relationship: Saturation capacity: Water content of soil when all pores are filled with water. Field capacity: Water content of soil after free drainage has taken place for sufficient period. Gravity water: Rainfall or irrigated water flow down to water table under gravity. Capillary water: Water held by surface tension … Read more
