ImpactofPoorD.U.Performance80AcreSystem
How to use this chart:If a grower wants to apply 3 acre feet of irrigation to all parts of the field, then depending on the degradation of Uniformity he must compensate by over applying in some of the field. This chart calculates the wasted water, energy and fertilizers based on the over application.
