Yermolaev M. Productivity of Sodicity-Affected Soils of the Forest-Steppe Zone of Ukraine and its transformation under the Influence of Reclamation

Object of a research: process of decrease of fertility sodisity-affected soils. The purpose of a research: installation of regularities and mechanisms a modification in fertility of sodisity-affected soils of the Forest-Steppe zone for development of ameliorative processes and methods of the ire improvement. Methods: field experimenting, laboratory and computer modelling, comparative analytical, chemical thermodynamics, variational statistics, information and logical analysis. Outcomes: are developed by a fundamentals in the research methodology and of productivity complex influence of the antropogeneous factors on basic elements and conditions of fertility naturally and technogenic induced salted end sodisity-affected soils, the features of their transformation under influence of hydraulic engineering and chemical amendments, system of fertilizations and soil cultivation. Novelty: consists in the substantiation and definition of a character of natural differentiation of soils, features of soils transformation of under antropogeneous influence of various intensity, estimation of the granulometric fractions in this process, development of the new methods of amelioration of natural and technogenic origin halomorphic chernozemic type soils. Degree of introduction: the state register of the completed scientific development - recommendation for cultivation of design yields of agricultural crops on irrigated soils, technique in calculation of norms in expenditure of gypsic ameliorative materials for chemical amelioration of sodisity-affected soils and improvement in the methods of definition estimation of parameters of theirs main properties. Orb of use: a system for protection of soils fertility - technological centre "State Fertility Center" Ministry of Agrarian Policy, for perposes of planning and practical realization ameliorative of measures in a zone of the Forest-Steppe
