Effect of fifty years of application of organic and mineral fertilizers on the fertility of a degraded chernozem of the central wooded steppe in the Ukraine Pravoberezhye. Report 5. Effect of systematic use of fertilizers in grain-beet crop rotation on some agrochemical properties of the soil


, : Effect of fifty years of application of organic and mineral fertilizers on the fertility of a degraded chernozem of the central wooded steppe in the Ukraine Pravoberezhye. Report 5. Effect of systematic use of fertilizers in grain-beet crop rotation on some agrochemical properties of the soil. Agrokhimiya ( 9): 53-62

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.
