N2  - Depletion of soil moisture by an irrigated perennial pasture is shown to be closely related to an evaporative index (E-R), the accumulated difference between evaporation ( E inches) and rainfall (R inches) subsequent to the last irrigation. This index, calculated for three types of evaporimeter, is shown to be directly proportional to (Et-R) the difference between Penman's potential transpiration (Et) and rainfall, for drying cycles of more than seven days duration. It is suggested that (E-K) might be a useful guide for irrigation scheduling, wherever Penman's estimate of potential transpiration is found to be reasonably accurate.
