Nitrogen Budgets from 31 U.S. Soybean Studies

31 soybean studies across the United States provide data on nitrogen budgets. The dataset includes R code for model fitting and figure generation, with biological N₂ fixation supplying an average of 53% of crop nitrogen demand. A neutral nitrogen budget would require 62% fixation.

Use Cases

• Fit Bayesian models using Rjags or JAGS to estimate N₂ fixation (BNF) rates from 15N data
• Calculate Nitrogen Balance metrics to assess sustainability across different agroecosystems
• Analyze the relationship between Biological Nitrogen Fixation (BNF) and crop nitrogen demand using the provided study data

Strengths

• Data aggregated from 31 distinct studies, providing multi-source validation
• Includes reproducible R code for analysis and visualization
• Dataset and code are publicly available under a CC BY 4.0 license

Limitations

• Limited scope at 206.1 KB, indicating a small, curated dataset
• Rows and specific column structure are unknown, requiring inspection before use
• Geographic coverage is limited to the United States
