Abstract: An irrevocable effect of the process of tillage erosion is truncation of the surface horizon and the translocation and accumulation of the eroded soil material at the foot of the slope. It concerns mostly fine soil fractions, humus and nutrients (C, N, P). The rate of that process depends on the original morphology of soil profiles and the susceptibility to erosion, the amount and intensity of precipitation, but mostly on the method and period of soil use. The aim of the paper was to determine the effect of the use of eroded Luvisols on the content of available phosphorus and the activity of phosphomonoesterases against the physico-chemical properties selected. Based on the analysis of variance, there was found a significant effect of the use of soils on the activity of phosphatases in the surface horizons of the analysed soils. There was found a significantly higher activity of alkaline phosphatase (0.094–1.896 mM pNP·kg–1·h–1) and acid phosphatase (0.152–2.905 mM pNP·kg–1·h–1) in the soil material sampled from the herbicide strips of 30-year apple tree orchards, as compared with the activity of those enzymes in arable soils, with a similar soil profile morphology (without Et horizon), grain size composition and the properties of the parent material. Activity of phosphatases in the soil surface horizon of the herbicide strips was positively and significantly correlated with organic matter. There was reported no significant effect of the use of the eroded Luvisols on the content of available phosphorus in surface horizons.
