Vol. of InfLow = Inches delivered to the field Vol. of Outflow = Inches of surface runoff OR Evaporation
Precip = Growing season effective rainfaLL estimate (20X sprinkler or 10X microspray)
Infiltrated Depth = Volume of inflow - Volume of outflow ETa = Evapotranspiration during growing season
D.P. = Deep percolation (Infiltrated depth - soil water deficit at start of irrigation)
Seasonal Irr. Eff. = (vol. of inflow - vol. of outflow - D.P. I vol. of inflow) x 100
