Land use change and stand age regulate soil respiration by influencing soil substrate supply and microbial community

Land use change and forest stand age are important factors in regulating soil respiration (Rs) in terrestrial ecosystems. However, the responses of Rs to these factors and the underlying mechanisms are not well understood, especially in fields converted from rice paddies (RPs) to upland cultivation. In this study, the characteristics of Rs and soil microbial community responses to land use changes from RPs to citrus orchards (ORs) with different...
