Abstract
The effect of 50 years of fertilizer application on chemical properties of a leached Chernozem in a crop rotation were studied in an experiment in the Ukraine. The extent of losses in ploughed and subsoil layers remained unchanged over 32 years, but for the end of the 50 year period reductions were 10% from the plough layer and 4% from the subsoil. The size of the losses depended on the fertilizer application method. Hydrolytic acidity in soil without fertilizer application increased over 50 years with a single liming by 238% (in comparison to initial value). Organomineral fertilizers decreased the rate of soil acidification. Mineral fertilizers showed a small increase in hydrolytic acidity of soil compared to initial values.
