MORPHOLOGICAL AND HYDROPHYSICAL PROPERTIES OF CULTIVATED DEPLETED PEATLANDS
The article presents the data on agroecological assessment of the agrophysical properties of cultivated depleted peatlands under controlled water regime used in feed production. New varieties of soil formed in the process of agricultural development are identified and described. Their close arrangement to each other established in the course of this study, shows a wide range of agrophysical indicators within the root zone of studied territory. Properties and character of interbedded of granulometric composition of depleted peatlands profile to a depth of several meters were disclosed. Within the object under study, almost all known subclasses of grounds used in soil science were found. Due to the fact that in some sand samples content of sand fractions, pebbles and gravel is close in value, the authors introduced an additional term "various granular". The article presents the description of mineral bed of peatbog "Gadovskoe", which was formed with participation of rocks of different genesis, overlapping each other in unpredictable ways. The peculiarity of the object under study that lies in the fact that the profile is based on the sharp change of parent rocks of different genesis, which puts it together with binomial deposits. The paper also attempts to assess the potential impact of periodic flooding on the "weighting" of granulometric composition of soil profile light mineral horizons due to the transfer of clay fractions from heavier horizons. Characteristics of the state of cultivated depleted peatlands confirm their suitability for the production of feed. However, soil diversity and heterogeneity of the soil profile largely complicates the implementation of some agrotechnical operations.
