The investigation was carried out during the years 1997-2000 and 2008-2009 under the production conditions of the marginal region of north-eastern Slovakia. The aim of the research was the monitoring of the basic chemical soil properties (pH, Ntotal, Ninorg, Pavail, Kavail, Mgavail, Cox) in relation to soil enzymes (acid phosphatase, alkaline phosphatase, urease), in the conditions of sustainable use of soil in the temporal and spatial dimension. From the point of view of application of ecological approaches in plant production, the biologically balanced rotation of crops was applied with adequate proportion of plants that regenerate soil fertility and protect the environment. Monitored biochemical soil properties did not changed significantly during the research period. High doses of organic fertilizers had positive effect on soil productivity, and thus indirectly on maintaining soil pH, available nutrients content, retention of humus in soil and promotion of natural protection of soil enzymes. Linear regression showed significant dependence between content of Cox and alkaline phosphatase, between available potassium and urease and between available magnesium and urease, acid phosphatase and alkaline phosphatase.
