total carbon in surface residue and soil humus wt = sol_bd(1,j) * sol_z(1,j) * 10. (tons/ha) -> wt1 = wt/1000 organic n leaving hru update soil carbon organic nitrogen pools Calculate runoff and leached C&N from microbial biomass microbial carbon loss with runoff and sediment - first soil layer cb_wtr_coef%prmt_44 is the ratio of soluble C conc - runoff/perc (0.1-1.) microbial carbon loss with sediment percolation and lateral flow of microbial carbon in lower soil layers calculate carbon in percolate and lateral flow
