Importance of grass cover in reduction of negative processes in soil affected by air pollution

Popis výsledku v původním jazyce

The effect of grass sward formation on soil environment was studied on a site affected by air pollution in the Moravian-Silesian Beskydy Mts. (Czech Republic). Acidophilous grasses (Calamagrostis arundinacea and C. villosa), common on clear-cut areas, were planted in blocks of soil inserted in plastic boxes modified to lysimeters. Their intensive growth resulted in a decrease of both the acidity of the soil percolates and the amount of nitrogen, especially of nitrates, in lysimetric waters leached fromsoils. Leaching of base cations (Ca2+ and Mg2+) was two to three times lower as from bare soil without grasses. An excess of labile Al was substantially eliminated in variants with grasses. Formation of a grass sward also coincided with a considerable decrease of conductivity of percolates. The biomass of soil microorganisms increased by 30% in variants with grasses.Thus, it is suggested that grass sward formation has a positive effect on the reduction of nutrient losses.
