The objective of this study was to assess the effect of biochar soil
amendment (BSA) on chemical and microbial properties in different
agricultural soils in Vojvodina Province. Short-term pot experiment
consisted of five biochar application doses (0, 0.5, 1, 2, and 3%) and five
contrasting soil types (Mollic Gleysol, Eutric Cambisol, Calcaric Fluvisol,
Gleyic Chernozem, and Haplic Chernozem), planted with sunflower (Helianthus
annuus L.) and winter wheat (Triticum aestivum L.). The examined chemical and
microbial properties were significantly influenced by soil type and
interaction of experimental factors. Significant influence of biochar on the
contents of calcium carbonate (CaCO3), total nitrogen (N), total carbon (C),
soil organic carbon (SOC), humus and potassium (K) of the tested soils was
observed. Biochar also significantly affected the number of azotobacters
(AZB), fungi (FNG), actinomycetes (ACT) and copiotrophic bacteria (CB). The
effect of BSA varied depending on the applied dose, with higher values of the
examined chemical and microbial parameters at higher doses of application.
Further studies on using biochar in soils with low fertility will be
necessary to establish its efficiency as an enhancer for agricultural
production in Serbia.
