Effects of biogas slurry application on peanut yield, soil nutrients, carbon storage, and microbial activity in an Ultisol soil in southern China

摘要

Biogas slurry (BS) was known to influence soil-plant ecosystems when applied as a fertilizer, especially in combination with a chemical fertilizer (CF). Limited information was available regarding how this combination of BS-CF actually affected the soil-plant ecosystems. The purpose of this study was to evaluate the effects of BS-CF combinations on peanut yield, soil properties, and carbon (C) storage in a red soil (Ultisol) in southern China.
