" Print the page Irrigation scheduling is the decision of when and how much water to apply to an irrigated crop to maximise net returns... Irrigation and rainfall add water to the root zone... Following heavy rainfall or irrigation, water will drain out of the root zone until the Drained Upper Limit (DUL) is reached (also known as Field Capacity) - this is the amount of water that the soil can hold against gravitational forces...

Water use efficiency is calculated as the ratio of grain yield (kg/ha) to total water used (mm)... Other experiments with barley in Mediterranean locations showed a threefold increase in water-use efficiency in response to fertilisation, but the fact remained that (even with adequate nutrition) for each millimetre of water used productively in crop transpiration, one or two millimetres were wasted through soil evaporation... In summary, unproductive terms of the water budget - chiefly soil evaporation - are major constraints for the achievement of high water-use efficiency in dry environments...
