RC-P, model to calculate the long-term recovery of applied fertiliser phosphorus

RC-P is a simple model to calculate the long-term effect of fertiliser phosphorus application(s) on crop P uptake and yield. The input data are mainly derived from  a one-year P-fertiliser trial on a representative crop and soil combination
