Forecasting of microelement status of soil system for efficient remediation and using

Abstract

Grounded the method for forecasting of the heavy metals (HM) and trace elements (TE) mobile forms content in the
soil system on the example of surveyed soils of different genesis on their trace element status in different climatic
zones of Ukraine, contaminated soils around Zmiyiv TPP PJSC "Tsentrenergo" NJSC "Energy Company of Ukraine"
Kharkiv Region, JSC "Ukrtsynk" and JSC "Avdeyevka Coke-Chemical Plant" Donetsk region climatic zones of Foreststeppe and Steppe zones of Ukraine and and soils of the Lviv region of Western Forest-steppe zone of Ukraine on
the effectiveness influence of organic-mineral, organic and mineral fertilizing systems. Elaboration of the method
include conducting a patent search; field stage - soil-geochemical research on the local and regional levels, including
the conditions of the technological load on the soil and the conditions for sustainable impact of pollution emission
sources of inorganic nature; fixed a series of field experiments; analytical stage of determining performance of soils
properties; in-office stage - the assessment of trace element status of soils for expert evaluation of regulatory
reference documentation, statistical data processing. The essence of the utility model: by defining an additional
indicator of hydrolytic acidity of soils with application of organic-mineral and /or mineral and / or organic fertilizing
systems and technogenic pollution by the HM and received by the established mathematical models dependences of
hydrolytic acidity, group composition of humus, and ME and /or HM mobile forms content in the soil provided an
effective prediction of their content with the subsequent extension of the method algorithm on other types of soils
which ensures the universality of the method, the express receipt and improving accuracy of the predicted values of
the TE and HM content in soils. Technical result: providing the possibility to increase the accuracy and forecasting the
express content of chemical elements in soils of different genesis with simultaneous increase remediation capacity of
the soil of a particular type by expanding the range of informative indicators for predicting the content of HM and TE
mobile forms in the soil system.Distinctive features and benefits of the proposed technical solution in comparison with
known methods and approaches are the express receipt and improve the accuracy of predicted values of the TE and
HM content in soils; universality of the method for all types of soils of different climatic zones of Ukraine.A method of
trace element status prediction system for soil remediation and the effective use should be used in agroecology on
issues of diagnosis, assessment, forecasting and TE status danger of excessive accumulation of HM in soils;
including technogenic contaminated, for elaboration ways of contaminated areas remediation, as components of
complex methods of environmental remediation of soils and, consequently, to reduce man-made and technological
loads on soils of different genesis, intensity of their degradation and recovery properties. A new methodological
approach protected with patent (patent for utility model 95649 UA 2014).
