Abstract
To determine the influence of soil acidity on growth of perennial grasses and soil biological properties, experiments were performed with variable soil acidity: naturally highly acidic (pHKCl 3.9) and medium acidic (pHKCl 5.0). Four perennial grasses mixtures were cultivated. The mixtures where composed of one variety of legume and two grasses: Trifolium pratense L., Trifolium repens L., Trifolium hybridum L., Medicago sativa L. (each of 50%) with Phleum pratense L. (35%) and Poa pratensis L. (15%). The aim of this study was to assess the impact of soil acidity on different perennial grass mixtures’ growth and development, and on soil biological properties. Root distribution in the soil profile was determined by the plant species. The negative effect of highly acidic soil was shown on the mixture with Trifolium hybridum L., where the amount of roots at 0-10 cm soil depth was lower by 44.2% (P<0.01) in the second year of development. In the mixture with Trifolium repens L., roots developed better in highly acidic soil; the total amount of roots was 2.5 (P<0.01) times higher than in medium acidic soil. Although differences were found in root development, the total aboveground mass of perennial grass mixtures showed better growth in medium acidic soil.
