The effect of influence of high doses of manures on mobility of phosphates in soils is defined by their dose, selective ability of functional groups PPK and fertilizers to phosphates, iron, aluminum, calcium. Mobility of contributable phosphoric fertilizers is defined by sequence of entering of manures and fertilizers.
