Effects of Microbial Inoculants and Organic Amendments on Wheat Nutrition and Development in a Variety of Soils

Abstract Manipulation of soil microbial communities through inoculants or amendments can improve crop nutrition. However, to what extent these benefits vary depending on properties is not yet understood. Thus, here we studied the effects and application labile organic C yield uptake micronutrients P in wheat ( Triticum durum ) different soils. The Bacillus subtilis QST713, Trichoderma asperellum strain T34, cellulose was tested ten soils varying greatly a pot experiment. Microbial increased dry matter (between 5 10%) grain 15 20%), regardless soil. Some treatments triggered nutrient mobilization mechanisms such as phosphatase oxalate production. total Zn plants did increase with treatments, their effect Fe Mn varied B. T. improving by decreased increasing pH also activity Inoculants harvest index P-to-Zn ratio grains independently This probably ascribable changes distribution phytohormones plants. Microorganisms improved yield, portion absorbed accumulated grains, quality. These depend nutrition affected activity.
