China Cropland Nitrogen Budget And Soil Acidification Projections 1981-2100

310.3 KB of data evaluates nitrogen budget dynamics in China's cropland from 1981 to 2020 and projects future scenarios from 2021 to 2100. The dataset, authored by Yue Dong, applies the H⁺ budget model to quantify provincial-level soil acidification rates under different Shared Socioeconomic Pathways (SSP1-SSP5).

Use Cases

• Analyze nitrogen budget dynamics across provinces under different SSP scenarios to assess environmental impacts.
• Model provincial-level soil acidification rates using the H⁺ budget process for long-term agricultural planning.
• Project future nitrogen use efficiency (NUE) trends based on population and dietary structure change scenarios.
• Compare historical (1981-2020) and projected (2021-2100) nitrogen budget data to evaluate policy interventions.

Strengths

• Covers a 120-year time range from 1981 to 2100, combining historical analysis and future projections.
• Provides data at the provincial level for China, enabling regional comparative studies.
• Includes multiple future scenarios (SSP1-SSP5) incorporating population, diet, and N management strategies.

Limitations

• The dataset is 310.3 KB, indicating a limited scope and likely aggregated or summary-level data.
• Projections from 2021-2100 are model-based and depend on the assumptions of the SSP scenarios and NUE strategies.
• Row and column counts are unknown, making it difficult to assess the granularity of the underlying data.
