Nitrate Losses--Leaching, Surface Runoff, Lateral Subsurface Flow

The amount of NO₃-N lost when water flows through a layer is estimated by considering the change in concentration. Thus, the equation

where VNO3 is the amount of NO₃-N lost from a soil layer and c_N03 is the average concentration of NO₃-N in the layer during the percolation of volume QT through the layer. At the end of the day, the amount of NO₃-N left in the layer is

where WNO3₀ and WNO3 are the weights of NO₃-N contained in the layer at the beginning and ending of the day. The No₃-N concentration can be calculated by dividing the weight of NO₃-N by the water storage volume:

where c_NO3 is the concentration of NO₃-N at the end of a day, PO is soil porosity, and bl is a fraction of the storage PO occupied by percolating water. Equation 159 is a finite difference approximation for the exponential equation

Thus, VNO3 can be computed for any volume, QT, by integrating equation 160

The average concentration during the percolation of QT (1 day since EPIC is a daily time step model) is

Amounts of NO₃-N contained in runoff, lateral flow, and percolation are estimated as products of the volume of water and the concentration from equation 162. The calculation sequence is: (1) Soil layer 1--Leaching is estimated first by substituting 0 for QT in equation 161 and solving for VNO3. Then VNO3 is removed from WNO3₁ and placed into WNO3₂. Next, runoff and lateral flow losses are estimated simultaneously by substituting Q+QR, for QT in equation 161 and the resulting VNO3 into equation 162. Individual losses are estimated for runoff (Qc_NO3) and lateral flow (QR₁c_NO3). Finally, these losses are removed from WNO3₁. (2) Soil layers 2-M--Leaching and lateral flow losses are estimated simultaneously by substituting QR+O for QT in equation 161 and the resulting VNO3 into equation 162. Individual losses are calculated as in (1) (QRc_NO3) and (Oc_NO3), subtracted from WNO3 and added to WNO3₊₁. The process is repeated layer by layer to the bottom of the soil profile.
