Аннотация: The effect of commercial humic product Lignohumate® on the biological activity of Latosol under long-term agricultural use with application of pesticides at the Bali Island (Indonesia) was evaluated in model experiments. It was shown that the application of lignohumate in a concentration gradient 0.025–2.5 mg/g resulted in increase in soil microbial community respiration rate by 10–30%, proportionally to the rate applied. As the application rate of Lignohumate increased, a significant threefold increase of nitrogen fixation intensity caused by the activation of bacteria of the Oxalobacteriaceae family was observed. In general,the bacterial community of Latosol consisted of more than 85% of the representatives of four phyla: Proteobacteria,Firmicutes, Chloroflexi, and Acidobacteria. Lignohumate at application rates higher than 0.025 mg/g promoted an increase of methane formation, whereas gaseous nitrogen losses due to denitrification reduced. An important practical conclusion on the reduction of a toxic effect of pesticides in the presence of lignohumate and its positive effect on soil biological activity and nitrogen balance in the Latosol under intensive agriculturaluse was made.
