Potential fertility is determined by many soil properties; mechanicalcomposition, water-physical and chemical properties, including structure, contentand qualitative composition of humus, humus layer capacity, total nitrogen and phosphorus content, pH, etc. As a result of long-term agricultural use and erosionprocesses, these soil properties undergo significant changes. These changes can go in the direction of both improving and cultivating soils - in scientific farming using techniques to increase their fertility, and depleting, “plowing” the soil, up tothe destruction or a sharp decrease in their fertility by erosion processes - with extensive farming.
