ABSTRACT
The soil line concept has great potential for soil studies as variations in soil line parameters can be the indicators of spatial variations in color-inducing soil properties. It was found that soil cover of the test area is characterized mostly by soil line slope values ranging from 0.1 to 3 and negative intercept values (80% of the studied area). Statistical analysis showed that slope of the soil line decreases with increase in humus content and steepness, with the rise in the content of coarse silt up to 40% and in the content of medium and coarse sand up to 20%, the transition from loamy sandy to clay soils. Intercept demonstrates the inverse relationship. Best results during Random Forest modelling were achieved for humus and coarse and medium sand content. Variations in soil line parameters explain about 23% of their variance.
