Dynamic of selected physical, chemical, and biological parameters as affected by water erosion

Original language description

Intensive agriculture is the main factor of decreasing soil quality and soil degradation. The maintenance of soil organic matter can reduce these negative consequences and increase the stability of agro-ecosystems. The rate of soil organic matter accumulation depends on particle size distribution and soil chemical and biological properties. Soils high in soil organic matter are supposed to be more resistant against water erosion and have better water retention and sorption capacity. This study is aimed at the assessment of changes in selected soil properties in the transect control site (Calcic Chernozem (Loamic)) - erosion site (Calcaric Regosol (Loamic)) - accumulation site (Colluvic Calcaric Regosol (Loamic)). The soil types were classified according to the IUSS Working Group WRB (2014). The particle size analysis, porosity, density, bulk density, aggregates stability, total organic carbon and nitrogen content, humic substances content, nutrients content, microbial biomass and basal soil respiration were evaluated during the period 2018-2022. The selected parameters were determined by standard analytical methods according to Zbíral et al. (2016). Results were processed by one-way ANOVA analysis and Fisher test (p<0,05). Results showed that erosion statistically significantly affected aggregates stability, total organic carbon and nitrogen content, and humic substances content. Soil biota was under the stress and the degrease of microbial biomass and basal soil respiration was determined.
