The comparison of soil physical properties of conventional tillage and minimum tillage
 HEJDOVÁ, Anna
Some chosen physical properties have been observed in the field experiment on the land of Stagra, s. r. o., Studená in 2009. There have been compared two technologies "minimum tillage" (MT) and "conventional tillage" (CT). There was evaluated especially bulk density (Or), porosity and soil compaction. Bulk density was statistical significantly higher under conservation tillage than under ploughing in soil profil at the depth to 0,2 m. But at the depth more than 0,25 m bulk density was higher (it means less favourable) under CT than under MT. It can be concluded, that the minimum tillage doesn´t deteriorate the compaction in the subsoil. The average values were not higher than critical levels of damaged compaction for sandy-loam soil. The soil compaction measurement confirmed this trend. The values of total porosity (Pc) show nearly the same conclusions as Or. The most favourable values of Pc occur in topsoil, which is tilled.
