University of Nebraska  Lincoln R School of Natural Resources SMI maps The soil moisture index (SMI) scales the fraction of available water in a 50 cm (~20 in.) profile Scaled such that 0.0 is the equivalent of 50% available water –5.0 represents a soil at field capacity and -5.0 represents a soil at wilting point Measured under grass cover –Can be used to approximate soil moisture in nearby grain fields

University of Nebraska  Lincoln R School of Natural Resources Surplus or Deficit maps The surplus or deficit maps show how much water: –Is needed to get the soil profile back to 50% available water (shown on the map as a deficit) –Is left in the soil profile before the 50% threshold is reached (shown on the map as a surplus) The colored dot represents the SMI at that location Irrigation scheduling possibilities?
