Impact of vermicompost on biological indicators of the quality of soil under maize in a greenhouse experiment

Popis výsledku v původním jazyce

The objective of this study was to determine the effect of vermicompost application on above ground dry matter biomass, microbial biomass carbon (MBC), dehydrogenase activity (DHA), and functional diversity of microbial communities (BIOLOG assay using EcoPlatesTM) in the cultivation of maize. The greenhouse experiment included variants: control (no fertilizer), CAN (mineral fertilizer calcium ammonium nitrate 30 kg N/ha), V20+CAN (vermicompost 20 t/ha+mineral fertilizer 60 kg N/ha), V40 (vermicompost 40 t/ha) and V80 (vermicompost 80 t/ha). Soil samples were analysed at the start and an end of the experiment (after 74 days). We observed the positive impact of vermicompost on above ground matter biomass of maize, but differences in comparison to control were not statistically confirmed. The more pronounced influence of fertilization on biological parameters was found at the end of the experiment. MBC was statistically significantly higher in variants V40 (14.8%) and V80 (32.4%) than control. Application of CAN had significantly negative effect, but combination of V20+CAN had positively influence of dehydrogenase activity. However, soil BIOLOG data indicated that the Shannon diversity index and evenness were significantly the lowest in V20+CAN variant. The study suggests that vermicompost improves soil quality and represents a suitable alternative to mineral fertilizers.
