~ ~ ~ PURPOSE ~ ~ ~
this subroutine calculates the amount of phosphorus lost from the soil
profile in runoff and the movement of soluble phosphorus from the first
to the second layer via percolation

compute soluble P lost in surface runoff units ==> surqsolp = [kg/ha * mm] / [t/m^3 * mm * m^3/t] = kg/ha compute soluble P leaching leach p from bottom layer perc p to next layer tile p
