Intercropping with soybean enhances walnut rhizosphere soil physicochemical conditions, microbial community composition, and ecosystem multifunctionality
Intercropping is a sustainable agricultural practice known to enhance farmland biodiversity and productivity. However, research on rhizosphere microbial communities in walnut-soybean intercropping systems remains limited. This study investigated a 5-year-old orchard on the Loess Plateau. Rhizosphere soil cha...
