Simplified Forms of Deep Percolation Estimation Method below the Crop Root Zone for Silt-­Loam Soils

Deep percolation (DP) is an important variable in hydrologic cycle and water balance analyses. It also is important when quantifying crop water use (evapotranspiration), irrigation requirements (IR), recharge analyses, nutrient and micronutrient movement in the soil profile and below the crop root zone, and other analyses.
