The mineral background of the anthropogenic soils of landscape architecture objects

During the creation of landscape architecture the mineral background of natural soils is transformed and new artificial soils are created. The mineral content and the grain texture of an anthropogenic changed soil of the Arkhangelskoe manor museum were studied as an object of a landscape architecture. The degree of transformation of the natural soils was evaluated. The features of constructozems were determined: the significant sandiness of the upper part of the profile, high variability of distribution of soil grain fractions, the changes in concentrations of the share participation of minerals and their distribution, and also the mismatch between the degree of weathering of the mineral component and the absolute soil age. According to the data we obtained, practical suggestions for forming of organic-sandy mixtures, which are used for anthropogenic soil construction, were made.
