Selected physical properties of fallowed mountain soils

The object of investigations were mountain soils derived from various parent rocks which were fallowed during five and ten years, in comparison to arable soils. The aim of the research was to characterise physical properties of the fallows and adjoining arable fields. The obtained results point to higher values of porosity, bulk density as well as content of total carbon of fallows in comparison to arable soils. On the analysed fallows far higher growth of weed with high contribution of many-year species was found,
