A prognosis model of the content of nitrogen fractions in the soil with organic matter change is developed. Average diagnosis criteria of fraction content of nitrogen in peat soils of different evolution stages are presented. Natural un-drained peat soil, agricultural peat soil, mineral peat soil and mineral residual peat soil is researched. Dependence of total nitrogen and its fractions content in soil on organic matter content is shown. It is established that after drainage and agricultural long-term application of peat soils (for about 50 years) there appear mineral peat soil complexes that differ significantly in terms of quantitative and qualitative nitrogen fraction composition. The models of prediction of nitrogen fractured content in soil when changing the amount of organic matters in it and the approximate diagnosis criteria of the nitrogen fraction composition in peat soils on different stages of evolution (that can be used in various soil studies) are represented in the article.
