Garden with Insight v1.0 Help: Soil patch next day functions: in lower soil layers, calculate labile P loss in percolation

In soil layers below the top soil layer, labile P is lost only due to percolated water. Of course, as with nitrate, the labile P is only really lost from the last soil layer, because phosphorus moving out of each layer moves into the layer beneath it. Labile P moving down the soil during percolation is calculated simply using the concentration of labile P in the percolated water (as calculated by the amount of labile P in the layer and the layer weight). The concentration is multiplied by the amount of percolating water to obtain the amount of labile P moving out of the layer.
