Description
A three-year field experiment (2022–2024) measured the effect of soil amendments on soybean yield and soil remediation in soda saline–alkali land. The dataset, created by Mingfen Shan, compares four treatments across three soil depths (0–10 cm, 10–20 cm, 20–30 cm) using a Soil Quality Index. The citric acid treatment resulted in a 42.67% soybean yield increase.
Use Cases
Modeling the relationship between soil amendments and soybean yield based on reported yield increase rates.
Analyzing changes in soil chemical properties (e.g., pH, available nutrients, exchangeable sodium) across different soil depths.
Comparing the effectiveness of citric acid, biochar, and organic fertilizer treatments on soil quality index (SQI) improvement.
Evaluating the synergistic effect of amendments on soil fertility and salinity regulation for ecological restoration planning.
Strengths
Data is based on a three-year field experiment (2022–2024), providing longitudinal context.
Results are quantified with specific percentages for yield increase (42.67%) and soil property changes.
Analysis covers three distinct soil depths (0–10 cm, 10–20 cm, 20–30 cm) for stratified understanding.
