Abstract
The aim of the study was to determine the effect of increasing potassium fertilization (0, 140, 190, and 240 mg K2O/kg of soil) in the interaction with nitrogen fertilization (130 and 170 mg N/kg of soil) on the trace elements content in the typical, non-contaminated agricultural soil. The trace elements content in the soil depended on nitrogen and potassium fertilization. Potassium fertilization had a more significant effect on trace elements content in the soil fertilized at the same time with a lower nitrogen dose (130 mg N/kg soil). Increasing potassium fertilization increased the content of cadmium by 83% and lead by 32% and reduced the amounts of chromium by 10% and iron by 3% in the soil, particularly in the series with a lower nitrogen dose (130 mg N/kg soil). The effect of potassium fertilization on the content of other trace elements was less unambiguous since, for most of trace elements, lower doses of this fertilizer contributed to growth of trace element, while higher doses lead to a decrease in their accumulation in the soil. Nitrogen fertilization increased the contents of zinc and iron—3%, copper—9%, manganese—12%, chromium—15%, and cobalt—59%, while reducing the contents of cadmium and nickel—24% and lead—45%. Permissible standards for trace elements content in the soil have not been exceeded.
Highlights
The growing world population is increasing the demand for food, and in highly developed countries consumer requirements necessitate the production of high-quality foods
In the lower nitrogen dose series (130 mg N/kg soil), changes were observed in the contents of all analyzed trace elements in the soil under the influence of increasing potassium fertilization, as compared to the control pot (Tables 2 and 3)
The most unambiguous effect of potassium fertilization was observed for lead, chromium, and iron, with positive relationships observed for lead, and negative relationships for chromium and iron
Summary
The growing world population is increasing the demand for food, and in highly developed countries consumer requirements necessitate the production of high-quality foods. The production of large amounts of food and feeding stuffs requires the supply of agricultural raw materials of plant origin on an adequate scale, which, in turn, is closely linked to securing the fertilizer needs of plants. This would not be possible without the application of mineral, natural, and organic fertilizers to agricultural fields in a proper ratio, in doses adapted to the nutritional and fertilizer needs of individual plant species [1,2]. The application of mineral fertilizers in doses recommended for crop cultivation is not expected to result in an excessive uptake of trace elements by plants [3,8]
