Co-application of wood ash and Paenibacillus mucilaginosus to soil: the effect on maize nutritional status, root exudation and composition of soil solution

Popis výsledku v původním jazyce

Novel strain of potential plant growth-promoting bacterium (Paenibacillus mucilaginosus ABi13) was tested for its ability to increase the plant availability of nutrients from wood ash (WA) in P deficient soil-plant systems. Maize plants were grown in soil microcosms in semi-natural conditions, enabling rhizospheric- and bulk-soil solution analysis with special emphasis on low-molecular-mass organic acids (LMMOA). Wood ash, as a sole fertiliser, increased biomass yield and improved nutritional status of maize plants. Concomitantly, application of WA led to lower root exudation rates of malate and isocitrate likely due to improved P status of plants. P. mucilaginosus ABi13 was inefficient in mobilising P from plain, acidic soil, but increased P solubility in ash-amended soil. However, P. mucilaginosus ABi13 consequently decreased NO3 - concentrations in soil solution and induced N deficiency in maize, which led to decreased biomass yield and LMMOA exudation rates.
