I am modelling nitrogen leaching in soil under pasture following urea application. I have successfully modelled field nitrogen leaching and crop uptake using HYDRUS 1D using the standard solute transport module but would like to also use HP1 to model the same data to include geochemical reactions by...

Hi I am simulating P sorption in a sandy soil with surface charge properties dominated by FeOH minerals (goethite and haematite) and amorphous hydrous oxides. I have calculated sorbed P in PHREEQC using the function SURF("P", "Hfo") and the output represented very closely the measured P sorption iso...
