Some physical properties (such as the degree of mucking, muck depth, volumetric density, total porosity, moisture content), together with some chemical properties, (such as the value of absorbance λ 280, λ664, the content of exchangeable basic cations bound to the sorption complex, the content of hydrogen and organic carbon), and the biotic properties, (such as the number of microflora: amonificators, Actinomycetes and microorganisms using mineral nitrogen, and the biomass of invertebrates: saprophages, phytophages, predators) have been studied on meadow-sites situated on peat soils of differentiated peat origin and the period of dehydration. It has been observed that the studied properties differentiated the studied environments in a statistically significant way, and that the changes are correlated with the gradient of mucking.
