Abstract
The effects of mineral and organo-mineral fertilizers on soil physical properties of a Chernozem were studied over a 50 year period in the Ukraine. Systematic fertilizer application increased the use of productive moisture from evapotranspiration by 1.5-3%, water use of unit DM with mineral fertilizers by 7.2%, and with organo-mineral fertilizers by 13.5-17%. Fertilizer applications contributed to soil shrinkage.
