Název v původním jazyce

Comparison of aggregate stability within six soil profiles under conventional tillage using various laboratory tests

Popis výsledku v původním jazyce

Soil structure stability was studied in every diagnostic horizons of six soil using different techniques investigating various destruction mechanisms of soil aggregates. Soil aggregate stability, assessed by the index of water stable aggregates (WSA), varied depending on the organic matter content, clay content and pHKCl. Coefficients of aggregate vulnerability resulting from fast wetting (KV1) and slow wetting (KV2) tests showed similar trends of the soil aggregate stability as the WSA index, when studied for soils developed on the similar parent material. There was found close correlation between the WSA index and the KV1 value, which depended also on the organic matter content, clay content and pHKCl. Less significant correlation was obtained between the WSA index and the KV2 value, which depended on the organic matter content and clay content. The KV3 value depended mostly on cation exchange capacity, pHKCl and organic matter content.
