The Effect of Inoculated and Mitigated by Plants Biochar on Soil Microbiota

Popis výsledku v původním jazyce

Biochar application to the soil and its influence on soil physical, chemical and biological properties remains one of the most arguing topics last decades. Nowadays it is used as soil amendment in the terms of the strong negative impact mitigation of anthropogenic activities. Especially it may be found a lot of controversial statements regarding biochar's impact on soil microorganisms. Main representatives of soil microbiota such as key groups of microorganisms along with arbuscular mycorrhizal fungi considered to be sensitive indicators of soil state changes. Thus, in this study there is a try to enlighten the biochar's effect on soil microbiota and colonization of roots by arbuscular mycorrhizal fungi (AMF). Investigation involved five types of soil treatments with the lettuce as a model indicator plant (Lactuca sativa). Two types of bacterial inoculums applied to model plants in combination "with" and "without" the addition of the mineral fertilizer were exposed in controlled pot experiment. In order to avoid the estimation of the primary effect on plants immediately after the fresh biochar application, which could be partly deleterious, there were estimated only the results from the second generation, after the first plant generation has been harvested. The second generation of plants have been seeded into the same soil with the redosing the inoculum and fertilizers addition only. It has been analysed the colonization of roots by AMF and the total number of microorganisms including nitrogen-fixing bacteria, actinomycetes, spore-forming bacteria and micromycetes. Research results have shown of root colonization by AMF in the second plant generation with no significant differences between the treatments. The enumeration of different microorganism groups demonstrated sharp increase in all the applied treatments that corresponded to the root biomass increase as well.
