  1. Precip seasonal precipitation, ∆S change in soil water storage from planting to end of season, Deep Perc deep percolation loss of water below the root zone, ETc crop evapotranspiration, Evap estimated evaporation from wet soil, Trans estimated crop transpiration (ETc–Evap) between emergence and maturity (R6). All components except transpiration were cumulative between planting to 172 days after planting
