For continued healthy growth,an efficient schedule plans irrigation well before PWP.This is the allowable depletion(AD).Experimentation and judgment are needed to select a reasonable AD level of the soil reservoir capacity,which is based on the value of the planting,plant type,soil texture,and the season.A medium-value turf is typically managed at 50%AD,whereas a low-value turf could have an AD of 75% of the soil reservoir capacity.
