A method is given whereby the water requirements of a rostered irrigation scheme can be determined by considering the length of the roster period and the calculated soil moisture deficit at which irrigation is applied. From this the storage likely to be needed can be calculated. The method is computer processed so variations can easily be studied. An example of its application to the Irrigation Schemes of Mid-Canterbury, New Zealand is given.
