Characteristics and variability of dystric brown soils in posavsko forest economic district

Abstract

The paper presents a statistical analysis of the basic chemical characteristics of dystric cambisol, its depth and clay content in Posavsko forest economic district. The aim was to define the influence of pedogenetic factors (primarily parent rock) on the characteristics of dystric cambisols, using statistical analysis. The analysis was based on the data from the Interpreter of Soil and Typological Maps of Posavsko forest economic district. 35 soil profiles were analyzed. A and (B) horizons were analyzed separately, then compared with each other in terms of similarities and differences. Variability is greater in the A horizon. The values of variability, analysis of variance, linear and multiple regression, correlation and cluster analysis were determined. Three main subtypes were defined based on the results of chemical characteristics, depth, and clay content, namely: leached (4 profiles), humus (1 profile) and typical (30 profiles). The results show that the properties of this soil type are significantly influenced by the character of parent material.
