Sažetak
There is the strong decline of mouldboard ploughing during transition period from 90% to 60% of arable land in Slovakia due to economic, marketing and environmental reasons. For adoption of environmental sound tillage systems the research and dissemination is needed. The aim of research was to evaluate the influence of conventional and reduced tillage, FYM and residue management on soil bulk density (SBD) and porosity. The field trial was carried out over the period 2004-2006 at the experimental farm PD Kalná nad Hronom in south-western Slovakia. The sugar beet-spring barley- sunflower crop sequence was evaluated. The soil tillage treatments as follows: T1 conventional mould board ploughing with farm yard manure (FYM) application to sugar beet and incorporation of aboveground biomass of growing crops ; T2 conventional mould board ploughing without organic fertilization ; T3 no-till Horsch CONCORD CO 9. During June the soil samples were taken from 0.05-0.10m, 0.1-0.20m, 0.2-0.3m. The SBD and total porosity was highly significantly influenced by growing crops and weather conditions of evaluated years and SBD was also significantly influenced by tillage system. The positive effect of FYM on total porosity was noted in 2004 during sugar beet phase which is in relationship with SBD 1.266 t m3-1.279 t m3 in topsoil layers 0.5-0.20m. In subsequent evaluated years 2005-2006 the topsoil layers 0.5-0.20 m were more compacted with comparison to 2004 after first year of FYM application. In three year average, the conventional mould board ploughing with farm yard manure and incorporation of aboveground biomass form the most suitable soil environment (SBD 1.395 m3, total porosity 43.65%) but we also recommended the no-till (SBD 1.455 m3, total porosity 42.31%) for Haplic Chernozems in this specific area of Slovak region.
