The research shows that as a result of drainage and a long-term agricultural use (for about 50 years) peat-mineral soil complexes with different content of organic matters were formed along with peat complexes on the place of former peats. Its chemical composition changes greatly in the layer of 0–20 cm and especially in the layer of 21–40 cm with the reduction of content of organic matter in soils. Close correlations between the content of organic matter and the content of carbon, nitrogen, potassium, calcium, C:N ratio (R2 = 0.80–0.99) described by the appropriate regression equations are established; wеaker is correlation (R2 = 0.63–0.66) with magnesium, phosphorum and iron oxides changes in the content of which depend greatly on the application of fertilizers and dolomite meal.
