Soil chemical and microbial responses to combined compost tea and biochar application
This study investigated the effects of compost tea and compost tea combined with biochar on basil growth, antioxidant activity, tissue ion composition, soil chemical properties, and soil microbial communities under pot cultivation conditions. Three treatments were included: untreated control, compost tea, and compost tea plus biochar. The combined treatment altered plant ion composition and soil chemical properties, changed microbial community structure, and partially improved basil growth.
