ABSTRACT There have been microbiological and enzymatic analyses of soils located at different distances and in different directions from a wind generator (0 m, 20 m, 50 m, 1000 m) performed, in order to establish the impact of wind on the indicators researched. The biogenousity of soils is different for the individual samples, the total microflora is highest when the soil most heavily influenced by the wind – at a distance of 20 m from the wind turbine into the wind. Overall, the highest percentage share in the composition of the soil occupy the ammonification bacteria (non-spore forming bacteria and germs), followed by actinomycetes and micromicetes. The mineralization factor is lowest in the sample with the highest amount of micro-organisms and the highest in the samples against the wind direction and control. The cellulose activity is not limited by the wind erosion and its consequences – it is highest in soils in the direction of the wind and lower in the soil against the wind direction and the control point. Unlike it the catalase activity shows almost the same values in all soils tested. The microbiological and enzymatic indicators alone or in combination can serve as sensitive biological and biochemical indicators in the study of soils in the vicinity of wind turbines or influenced by wind erosion.
