Effects of Modified Chicken Manure Biochar-Based Bacillus velezensis Agent on Vegetable Growth, Saline–Alkali Soil Properties, and Microbial Communities
Soil salinization limits sustainable agriculture. This study used a citric acid–FeSO4 method to create modified chicken manure biochar (MCMB) as a carrier for the plant growth-promoting Bacillus velezensis SS-20, forming a biochar-based microbial agent (JS). A pot experiment included four treatments: CK (control), SS (...
