XDA28090203Dataset on Effects of Specialized Fertilizer Products on Soil Physicochemical Properties and Crop Yield in Semi-Arid Western Liaoning (2021-2025)
Listed in ScienceDB
This dataset originates from the sub-project "Development and Promotion of Specialized Fertilizer Products for Fertility Improvement in Semi-Arid Western Liaoning" (No. XDA28090203), part of the CAS Strategic Priority Program on "Black Land Protection and Utilization".
Description
It documents field positioning trial results from 2021 to 2025 in the semi-arid wind-sand soil and black soil transition zone of Fuxin City, Liaoning Province.
The dataset includes continuous observational data from three replicated plots under two treatments: "Blank Control" and "Core Treatment 1" (application of specialized fertilizer products with supporting technologies). Key indicators cover corn grain yield, slope, wind erosion amount, tillage layer texture (sand/silt/clay), soil physicochemical properties (organic matter, pH, CEC, bulk density, thickness), nutrient status (total N/P, available N/P/K), and qualitative assessments of management levels (irrigation, drainage, mechanization, etc.).
