Fertility and potentially toxic elements content in Mačva

Abstract

By examining the fertility of Mačva soil (fluvisol, humogley, eugley, chernozem, eutric cambisol, pseudogley, luvisol, vertisol), it was found that the soils with a reaction which is favourable for growth of most crops dominate, but about 25% of the samples, mainly on Pseudogley and Luvisol, have an unfavourable, highly acidic reaction. Soil organic matter content is generally medium to high, as are the nitrogen reserves. A low content of phosphorous was found in about half of the samples, while in about 10% of soil samples, a very high phosphorous and potassium content was found, as a result of soil properties as well as inappropriate fertilization. The PTE content and natural background values are around or below the values for Central Serbia. These values are below the maximum allowed limits in domestic regulations, except for Ni, whose content increased in some samples in the alluvium of the Drina and Sava rivers and in the soil in close vicinity. Locations with values above the natural background and limit values in the legal regulations require an additional analysis of the impact on the environment.
