Abstract:
The problem of growing ecologically safe vegetable crops with minimal economic costs in modern conditions of agricultural production is extremely urgent. At the same time, it is very important to study the features of heavy metals migration in the soil-plant system under the influence of fertilizers, as well as to justify the economic feasibility of their application. The article analyzes the aspects of translocation of heavy metals to vegetable produce under the effect of organic fermented fertilizer (made based on of chicken manure and peat), as well as a complex microbiological preparation. It was found that the use of organic fermented fertilizer and microbiological preparation under different fertilization systems decreased the intake of toxic metals – cadmium and plumbum – to carrots and cabbage heads, and increased the content of trace metals – zinc and copper. Separate application of 11 t/ha FF, integrated application of 5.5 t/ha with the Azoter formulation, as well as tillage with the formulation on the background of N30 provided a decrease of the plumbum intake rate in carrot root crops compared to the control by 34; 42 and 26%, cadmium – by 7; 14 and 28%, and increase the intensity of copper translocation in to roots, respectively, by 9; 5 and 6%, zinc – by 2; 3 and 1%. The intensity of plumbum intake in cabbage heads with the introduction of 10 t/ha FF separately, 5 t/ha in combination with a microbiological preparation and after application of the preparation on the background of N25 decreased by 20, 36 and 24% respectively, cadmium – by 17; 17 and 34%, and the conversion factor of copper in the product increased by 26; 10 and 7%, zinc – by 6; 2 and 1%. The economic expediency of using fertilizers for growing vegetable crops is also studied.
