Název v původním jazyce

Differences in microbial characteristics, organic carbon and nutrients contents and CO2-fluxes in soils under different tillage practices

Popis výsledku v původním jazyce

The selected microbial characteristics, organic carbon contents, concentrations of nutrients and CO2-fluxes were determined in field experiments in Prague ? Ruzyně (Czech Republic) with conventional (CT), reduced (RT) and no-tillage (NT) practices. The adoption of RT and NT increased in comparison with CT the microbial characteristics and soil organic carbon contents in the surface layer of the soil profile and consequently in the soil profile 0-30 cm. Contents of P, K and Mg, but not Ca, accumulated inthe surface layer of the soil profile in RT and NT. CO2?fluxes were determined in regular intervals after ploughing in 2008, 2009 and 2010. Warm and wet weather increased CO2-fluxes under CT in August 2008, lower CO2-fluxes were found under RT and NT. Hot and dry weather in August 2009 decreased CO2-fluxes. Later ploughing in September 2010 decreased CO2-fluxes from soils.
