The article present experimental equations of ash content and volume weight at various stages of the evolution of peat soils. An experimental dependence of the total moisture capacity of peat on its volumetric weight is also proposed. In the range of changes in volume weight, four zones are identified, reflecting the stages of evolution of peat soils.
