Effects of Fertilizer and Straw Management on Rice Yield and Emissions

A two-year field trial tested three nitrogen fertilization levels and three straw management practices in paddy fields. The dataset likely contains measurements of rice yield components, cumulative methane emissions, and soil nutrient content under different treatment combinations. Results show a 23.5% nitrogen reduction with 20% organic fertilizer substitution reduced cumulative methane emissions by 22.06%-28.81% while maintaining stable yields.

Use Cases

• Comparing rice yield stability under nitrogen reduction and organic fertilizer substitution.
• Analyzing the impact of deep straw incorporation on cumulative methane emissions.
• Evaluating changes in soil organic carbon and total nitrogen under different fertilization regimes.
• Modeling trade-offs between agricultural productivity and pollutant emissions (NH4+-N, NO3--N, TP).

Strengths

• Data originates from a systematic two-year field trial with controlled experimental treatments.
• Results include specific percentage changes for key metrics like methane emissions (reductions of 19.50%-28.81%) and soil nutrients.
• Dataset is openly licensed under CC-BY-4.0, facilitating reuse.

Limitations

• Column names and exact row count are not provided, limiting understanding of the data structure.
• The dataset size is given as 25011 bytes, suggesting a relatively small, likely summary-level tabular file.
• Geographic location and specific institution of the study author are not stated.
