Abstract

In the field experiment (2016-2018) in the conditions of the Krasnoyarsk forest-steppe the number of trace elements mobile forms were determined and the effect of soil organic matter and increasing doses of vermicompost on their distribution in luvic chernozem was studied. It is established that the studied vermicompost does not pollute the soil, which allows its widespread use in agriculture. The correlation and regression analysis obtained linear regression equations that reflect the relationship of the chemical element and organic matter in the soil after using increasing doses of vermicompost adequately. Elements with positive correlation and high significance level include Mn, Cu, Co and Zn.

Highlights

It is necessary to know the trace elements distribution in soils and plants for the development of sciencebased systems of fertilizer application in modern agricultural technologies. Both insufficient provision of arable soils with microelements mobile forms and their increased content can lead to the reduction in the ecosystems productivity, in addition, their high amount in the soil can be toxic to plants and worsen the quality of crops significantly [1]
With a shortage of content they are considered as trace elements, in excess - as heavy metals (HM)
According to the danger degree chemical elements are divided into three classes: 1- highly dangerous (Cd, Pb, Zn, As, Hg), 2 - moderately hazardous (Ni, Cu, Cr, Co, B, Mo), 3 - low-risk (V, Sr, Mn) [4]

Summary

Introduction

It is necessary to know the trace elements distribution in soils and plants for the development of sciencebased systems of fertilizer application in modern agricultural technologies. The aim of this work was to study the action of vermicompost organic matter on the trace elements distribution in the soil. Changes in the content of trace elements mobile forms in the soil under the influence of increasing doses of vermicompost were studied in the field according to the following scheme: 1) Control without fertilizers.
