2026-09-18 XDA28090205 Dataset on Integrated Technologies for Soil Nutrient Efficient Utilization and Fertility Cultivation doi:10.57760/sciencedb.iga.01264 en This dataset originates from field positioning experiments conducted as part of the sub-project "Integration and Demonstration of Technologies for Soil Nutrient Efficient Utilization and Fertility Cultivation" under the "Rejuvenation and Productivity Enhancement of Degraded Black Land in Shenyang Demonstration Area" project. It systematically records data from 2021 to 2023 on the screening and efficacy validation of phosphorus activators in typical agricultural regions including Lishu (Jilin Province), Changtu, and Chaoyang (Liaoning Province). The dataset comprises 8 Excel sheets, including background data and field experiment data categorized by year and location. It details the effects of different phosphorus activators (phytase, yeast peptide, phosphate-solubilizing bacteria, and their combinations) on soil phosphorus availability, microbial activity, and crop yield under reduced phosphorus fertilizer application, providing critical data supporting efficient phosphorus use and green agricultural development.
