Abstract

Models of changes in the acid properties of gray forest soils of the Opol’e region have been developed. It is shown that soil acidity increases at the application of phosphorus—potassium fertilizers and with increasing rates of the complete fertilizer. Organic fertilizers suppress the increase of soil acidity. The changes in the acid properties of these soils reflect the interaction of fertilizers with humus.
