Sorption and fractionation of dissolved organic matter and associated phosphorus in agricultural soil [PDF]
, 2007 Molibility of dissolved organic matter (DOM) strongly affects the export of nitrogen (N) and phosphorus (P) from oils to surface waters. To study the sorption an mobility of dissolved organic C and P (DOC, DOP) in soil, the pH-dependent sorption of DOM ...
