ABSTRACT
Biological element of the soil plays a key role in the soil ecosystem and its activity significantly contributes to improvement of the soil quality and health. Its activity is the result of a combination of the biotic, chemical and physical processes in the soil. The aim of this work is to monitor and to evaluate the development of physical and biological properties of soils within the time and spatial scales in conditions of sustainable land use. The study was carried out in model area in the marginal areas of the northeastern Slovakia during 2010 - 2013 (48º 57’N, 20° 05’E). Physical (bulk density, porosity, maximum capillary capacity) and biological (soil enzyme activity – urease, alkaline and acid phosphatase) soil properties were monitored and statistically evaluated. Via statistical testing we found that agroecosystems had a significant impact on the observed biophysical parameter. This study underscores the importance of longterm, quantitative soil monitoring for determining the changes in agricultural land and ecosystem processes over time.

Keywords: ecosystem of soil, physical properties, soil enzymes
