Approximate irrigation interval and application amount
for soils with 1 inch per foot water-holding capacity

Amounts shown are bases on 50% allowable soil moisture depletion(AMD) and
the average application efficiency for a well-designed and maintained center pivot or lateral
move irrigation system of 75%.
