Opis (eng)

Abstract: Soil structure is the natural organization of soil particles into different forms under the influence of pedogenic processes. The aim of this work is to determine the soil structure of ranker soils on Mount Maljen by analyzing the aggregate composition and water stability of structural aggregates, and to evaluate the soil structure using various soil aggregation indices. Thirteen soil profiles were studied and classified as ranker according to the national soil classification system. The following soil structure indices were determined: dry and wet mean weight diameter (dMWD and wMWD), dry and wet geometric mean diameter (dGMD and wGMD), structural stability index (SI), and structural coefficient (Kstr). The favorable aggregate composition of the studied ranker is illustrated by the wMWD/dMWD ratio of 0.81±0.10, the values of SI > 9% and Kstr > 2 in all soil profiles. The results indicate that the studied soils have favorable structure, high water stability and low risk of structural degradation, but various linear erosion processes observed in the field indicate that the study area is degraded and that soil structure is not the only factor stabilizing soil erosion.
