2026-06-15 A dataset of soil physical and chemical properties, phosphorus fractions, and phosphorus- solubilizing microbial communities in wheat-sweet potato rotation fields under different treatments in Luhe District (2020) doi:10.57760/sciencedb.26079 en Phosphorus (P) in soils predominantly occurs in insoluble forms, resulting in its low bioavailability. The bioavailability of soil P is influenced by multiple factors, including soil properties, P fractions, microbial communities, and crop types. Analyzing changes in soil physicochemical properties, P fractions, and P-solubilizing microbial communities under different fertilization practices in crop rotation systems can reveal the mechanisms of P activation, fixation, and transformation, thereby contributing to improving P use efficiency. The Luhe Monitoring Site in Nanjing is a nationally designated key monitoring point for non-point source pollution and represents a typical long-term positioning monitoring site for a sweet potato-wheat rotation system. This dataset is derived from this site, and includes soil P data collected after the harvest of wheat and sweet potato in 2020, as part of a long-term positioning experiment (involving 4 fertilization treatments) at the Jiangsu Cultivated Land Conservation Scientific Observation and Experiment Station, Ministry of Agriculture and Rural Affairs / National Agricultural Environment Liuhe Observation and Experiment Station. The dataset comprises 10 components: (1) experimental design of the long-term positioning trial; (2) fertilization details for different treatments in the long-term trial. (3) soil physicochemical properties after the harvest of wheat and sweet potato under different fertilization practices in 2020; (4) status of soil organic P fractions. (5) status of soil inorganic P fractions; (6) diversity of microbial communities involved in soil organic P mineralization; (7) diversity of microbial communities involved in soil inorganic P solubilization; (8) taxonomic composition of microbial communities involved in soil organic P mineralization; (9) taxonomic composition of microbial communities involved in soil inorganic P solubilization; and (10) the records of methods used to measure all indicators. Data collection and processing strictly followed the monitoring specifications for observation and experiment stations issued by the Ministry of Agriculture and Rural Affairs. Data quality was ensured through review and verification by laboratory quality control personnel and the project team leader. This dataset provides a reliable foundational for investigating the effects of different fertilization practices on soil P forms in soil, P bioavailability, and the mechanisms governing P dynamics.
