Qualitative evaluation of farmed luvic chernozem soils in central Moravia
Popis výsledku v původním jazyce
On six fields of the identical soil quality in district of the Kroměříž, soil samples were taken after harvest winter wheat from the depths of 15 ? 20 and 45 ? 50 cm for physical, chemical and biological analyses. Analyses of the topsoil and subsoil samples of luvic chernozem soils in the Kroměříž district showed that their bulk density exceeded the agroecological limit of 1.45 g.cm-3, that the minimum air content was below the limit of 10 %, and that the humus quality was low (HA:FA was less than 1). As compared with historical data, the relative saturation of adsorption complex was markedly decreased (from 90 % to 73 %). The calcium saturation of adsorption complex was insufficient (63 % vs. required 65 %), the basal respiration in topsoil was also low (0.59 mg CO2 per 100 g.h-1) and there was a relative lack of easily degradable organic substances in soil.
