Abstract: Fertilizing intensively plants with fertilizers a part of unspent nutritional elements of plants and not being mobilized into steady compounds migrates into deeper layers, consequently causing a danger to underground waters’ pollution. The aim of the work is to define a migration of alimentary materials ((NH4+), (NO2), (NO3), (PO43) in soil after using ecological fertilizers (Biofer and Activit). The base of the research is 35 samples in model systems of unmoved soil, top-dressed with ecological fertilizers (Biofer and Activit). Results of the research have shown that in the average heavy clayey soil the concentration of nitrogen compounds and phosphate in the soil depends on the amount of used ecological fertilizers (Biofer and Activit). After using Activit and Biofer fertilizers in 1 soil’s layer (10 cm) it has been set that the highest concentration of nitrites and nitrates is in 30 days after the soil was fertilized. The highest concentration of ammonium ions and phosphates has been set in 1 soil’s layer (10 cm) in 10 days after the soil was fertilized with fertilizers (Biofer and Activit).
