Coupling biochar with microbial inoculants improves maize growth and nutrients acquisition under phosphorous-limited soil

Coupling of biochar along with microbial inoculants could increase the phosphorus (P) availability and efficiency under the P-deficient environment. However, the effects of biochar and microbes on soil P retention remain still unconcerned in the subtropical environment. In the present study, AMF Glo...

Description
Summary:Coupling of biochar along with microbial inoculants could increase the phosphorus (P) availability and efficiency under the P-deficient environment. However, the effects of biochar and microbes on soil P retention remain still unconcerned in the subtropical environment. In the present study, AMF Glomus mosseae and Bacillus J 119 were applied as microbial material into two texturally different soils (soil A and soil B) amended with two different biochar (Rice husk biochar, RHBC; poplar wood chip biochar, PWBC). Both soils and biochar properties significantly affected the mycorrhizal root colonization. Soil amended with RHBC significantly improved the root colonization and root surface area in the no-P environment. Additionally, plant root and shoot biomass significantly enhanced in the combination of B + AMF. Moreover, B + AMF enhanced macronutrients (N, P, K, and Ca) and micronutrient concentration (Mg, Mn, Cu, and Zn) in plant root and shoot with biochars and in the no-P application. Overall, biochar application in both soils might increase the availability of nutrients especially P for maize plants. However, the responses of both biochar and microbial inoculants were varied with soil and biochar types which need in-depth investigations, especially its residual effects at field conditions in different climatic conditions before final recommendations.
