Feather-Based Compost Drastically Regulates Soil Microbial Community and Lettuce Growth in a Subtropical Soil: the Possible Role of Amino Acids

The role of soil organic nitrogen (e.g., amino acids) in regulating soil microbial community has not been well documented, which is much different from that of soil organic carbon. Feather-based compost (FBC) is rich in amino acids that can enhance soil life and microbial activity. Therefore, this study was designed to evaluate the possible role of amino acids in FBC in regulating soil microbial community. In pot experiment, FBC was applied to …
