Changes of soil biological and physical properties in consequence of different tillage systems of soil treatment

Popis výsledku v původním jazyce

The conventional tillage (CT), reduced tillage (RT) and no-tillage (NT) system s were performed on orthic Luvisol in site Prague from 1995. The effects of different soji tillage practices on some biological and physical characteristics were studied aftersix and seven years from the beginning of the experiment. Bulk density was greater in the top layer under RT and NT compared to CT. Bulk densities in deeper layers increased under more regularly under CT. RT and NT did not show significant differences between O.I-O.2m and O.2-0.3m layers. The soji porosity decreased in function of greater bulk densities in deeper soil layers. Soil organic carbon, microbial biomass and dehydrogenase activity increased in the top layer and decreased in O.1-O.2m and O.2-0.3m under RT and NT when compared with CT. The effects of soil tillage practices on basal respiratory activities were not pronounced among soil layers. However, the metabolic quotient (qCO2) reached greater values in deeper parts of RT and
