Abstract:The literature of long−term fertilization experiment in the Yangtze River Economic Belt from 1993 to 2023 was collected, and the data of farmland soil organic carbon were extracted and integrated. Using the normalization treatment and the analysis method of relative annual variation, the overall change of soil organic carbon content in farmland in the Yangtze River Economic Belt under long-term different fertilization measures was studied, and the change differences of soil organic carbon content under three t… Show more
