Forecasting the levels of chemical elements content in soils of different genesis for the assessment of their eco-energy status

Abstract

Grounded the new elaborated method for predicting of trace elements (TE) and heavy metals (HM) content in the soils of different genesis, which was elaborated by analysis the indicators parameters of their organic matter and energy characteristics in different natural-climatic zones of Ukraine, also of contaminated and intensive fertilizer soils. The method aims for the assessment of soils ecological-energy state due to the installation of the new natural relations of indicators humus, energy and elemental status of soils of different types, as a result, expanding the range of diagnostic indicators with identifing their paired combinations and simultaneously increasing of informativeness, accuracy, express testing of chemical elements (TE, HM) predicting levels, energy and humus state of soils to predict and ecological regulation of their quality. The essence of the elaborated utility model – by the identify of new patterns of soil properties indicators and receive four matching pairs of humus (CGA/CFA, Ctotal), elemental and energy state (calorific value of humus, the reserves of energy in the soil layer of 0–20 cm) as soil indicators with the using of mathematical-statistical analysis of the obtained regression equations for the accurate determination is predicted the TE and HM content in soils of different types of background conditions, with the distribution algorithm of the method for different soil types in certain climate zones in the conditions of technogenic pollution and technological load, risk and the presence of man-made pollution to make timely management decisions. Elaborated method ensures the rapidity of the assessment and improves the accuracy of the TE/HM status prediction, energy and humus state of soils of different genesis with the identification of soils ecological differences to predict their quality by assessment of ecological functions for the ranking of energy intensity indicators of the soil. The method is applicable in the environmental regulation of TE and HM content, regulation of the loads (technogenic, technological) on a soil system, agroecology to address issues of biological agriculture, bio-energy and energy of soil formation; monitoring the quality of humus and the status TE and the dangers of excess accumulation of HM, in the soil humus indicators and /or energy state; efficient environmental management of soils, both in background conditions and with different anthropogenic impacts and in the research practice. Grounded the method was examined on the of soils simples in different natural-climatic zones of Ukraine, contaminated soils in Kharkiv, Donetsk and Lugansk regions, and intensive fertilizer (organo-mineral, organic and mineral system of fertilizers) of soils in Kiev, Kharkiv, Poltava and Lviv region.
