Wooden biochar as a carrier for endophytic isolates

Abstract Plant growth promoting microorganisms (PGPM) serve as a basis for bio-fertilizers. The aim of this study was to evaluate the wood-derived biochar as a potential carrier for PGPM, previously isolated from plants. The selected microbial consortium was compatible with aged biochar obtained from tree branches and processed at temperatures of 600–800 °C. The effect of the consortium or biochar alone and biochar carrier-based bio-formulation on plant growth was estimated in a 14-day greenhouse experiment with barley. The length of shoots and roots increased by 46% and 32% respectively in comparison with control. Synergy of consortium with biochar was observed regarding root length. Conso…
