Biochar Application Improves Eggplant Yield in Association with Changes in Soil Microbial Communities and Soil Multifunctionality
Biochar is widely used to improve soil quality and crop productivity; however, the relationships among biochar addition, soil multifunctionality (SMF), microbial communities, and crop yield remain unclear. A field experiment was conducted from May to September 2025 in a continuous eggplant (Solanum melongena L.) croppi...
