Katsevych V. Agroecomikromorphological properties of technogenic soils under conditions of agricultural land reclamation (Nikopol manganese ore basin)

The dissertation is devoted to the study of the peculiarities of the formation of the microstructure of technogenic soils formed from Pleistocene-Miocene potentially fertile overburden rocks (forest-like loams, mixtures of red-brown clays and loams and gray-green marl clays) without coating and with coating of soil fertile lands. The most effective indicators of technogenic soils (technozem) transformation are determined, namely the appearance of the organic part in the plasma, the presence of biogenic microaggregates, pores, etc. It is noted that microaggregates of biogenic origin are common in the upper horizons, and microaggregates of lower horizons are of coagulation origin. It is established that the most characteristic neoplasms for pedozems are skeletons, clay and iron-clay cutanes.
