Abstract

The aim of this work is to assess the impact of Gumiton peat-based organo-mineral complex on the productivity and quality of carrots and the transition of 137Cs from soil to root crops under conditions of radioactive contamination. According to the results of field experiments on gray forest and soddy-podzolic soils of the Kaluga region of Russia, it is shown that leaf treatment with Gumiton of carrot plantings in different phases of crop development increases the yield of root crops by 20-40%, depending on the variety, soil type and agricultural background. Analysis of studies in the growing experiment on soddy-podzolic soil showed that Gumiton treatment increases the yield of carrots by 30%. The rate of decrease of 137Cs content is 1,2-1,25 times. Gumiton is a highly effective preparation for carrots, which increases the productivity and quality of the crop and helps to reduce the intake of 137Cs in root crops in radioactively contaminated areas.

Highlights

In Russian Federation, the territory of 21 regions was exposed to radioactive contamination after Chernobyl accident in 1986 y
According to the data of researchers who studied the accumulation of 137Cs in the crop yield on the soddypodzolic sandy loam soil of Polesie of Ukraine, it was found that among vegetable crops the values of transfer coefficient of 137Cs - CT137Cs (Bq/kg of root crops)/kBq/m2 in soil) in carrots, dill, parsnips, potatoes, Jerusalem artichoke, radishes are 0.1-0.2 [13]
"Potassium" therapy of radionuclide-contaminated lands was used in a timely manner by Belarusian agrochemists and soil scientists together with the “Belaruskali” enterprise to decontaminate soils and produce environmentally safe products after Chernobyl accident

Summary

Introduction

In Russian Federation, the territory of 21 regions was exposed to radioactive contamination after Chernobyl accident in 1986 y. As a result of Chernobyl accident, the southern part of the Kaluga region of the Russian Federation was contaminated, including with long-lived and biologically active radionuclides 137Cs and 90Sr. Carrots is one of the most important vegetable crops. It is rich in carotene (provitamin A) – up to 11 and more mg%, vitamins PP - up to 0.4 mg%, group B: B6 - up to 0.12 mg%, B2 - up to 0.06 mg%, vitamin C, folic acid, essential oil, carbohydrates and mineral salts containing a lot of Ca, Na, B, as well as Fe, P, Mg and other elements. The most valuable is considered to be β-carotene (it is more in red root vegetables), since it is 2 times more active than the α - and γ-isomers as a precursor of vitamin A [5, 6]
