Aberační změny u intenzivně obhospodařovaných černozemí
Indrová, Michaela
Diploma thesis: Aberration changes in chernozems as affected by their intensive exploitation is aimed at determination of selected physical and chemical soil properties, which indicate soil aberration. Introduction is aimed at the definition of soil, its important in the environment, and functions in the ecosystem. The experimental work is regarding aberration changes in Calcaric Chernozem (locality Velešovice, Czech Republic) as affected by agricultural exploitation. Soil properties were determined during the period 2013-2016. Results showed that studied soil has high aberration potential. Negative aberration changes included increasing of pedocompaction and bulk soil density, decreasing of porosity, structure stability, humus content, quality of humid substances and erosion.

Bachelor thesis is aimed at evaluation of anthropogenic changes in three selected subtypes of Chernozems. Object of study were -- Luvi-haplic Chernozem (Praha), Luvi-haplic Chernozem (Unčovice) and Calcaric Chernozem (Velešovice). We followed -- aggregates stability, texture, porosity, bulk density, total organic carbon content, soil reaction and buffering capacity. Results showed that studied heavy textured soils had high ability to pedocompaction. Agro-ecological limits were overstepped in Porosity, bulk density and total content organic carbon decreased. Exchangeable soil reaction also decreased and soil acidity increased. Buffering capacity again acids was also lower. Critical limits of pedocompaction were not overstepped but in subsoil horizons values were near to the limits.
