abstract:
The results of investigations on the impact of debris addition and thermal cycles on water retention and porosity of a light brown soil are presented. It was observed that debris addition and thermal cycles change the water retention and distribution of different groups of pores in the soil. The biggest changes were observed after the 1st and 2nd thermal cycles. The increase of rubble amount from 10 to 50% in the soil did not cause big differences in water retention. The decrease of medium pores amount under thermal cycles causes a decrease of soil water available for plants.
