Research on biochar in saline-alkali soils
this study addresses the following scientific questions: Does biochar improve the microbial community structure of saline-alkali soils by reducing soil salinity and enhancing nutrient accumulation, and does the effectiveness vary depending on the biochar feedstock? How does HA enhance the effectiveness of biochar, and what is its specific role in influencing microbial communities? What are the key environmental factors driving the structure and function of microbial communities in these soils?
