Soil carbon, nitrogen, and yield data from a 25-year winter wheat-fallow rotation experiment comparing no-till, stubble mulch, and moldboard plow treatments. The experiment, located on former short-grass prairie, includes at least three replicates per treatment and control plots of native sod. Information was compiled for the GCTE-SOMNET Database by researchers at IACR-Rothamsted, UK.
Use Cases
- Compare soil organic matter content and carbon:nitrogen ratio across no-till, stubble mulch, and moldboard plow treatments.
- Analyze crop yield response to different tillage methods under a winter wheat-fallow rotation.
- Model soil bulk density and texture (clay, silt, sand percentages) as predictors of carbon storage.
- Correlate local climatic conditions (temperature, rainfall ranges) with long-term soil nitrogen trends.
Strengths
- 25-year experimental duration provides longitudinal data on tillage effects.
- Site-specific soil properties include organic matter content (2.3%), bulk density (1.1 g/cm3), and texture percentages.
- Experimental design includes at least three replicates and control plots of native sod.
Limitations
- Exact row count, column names, and sample size for measurements are unknown.
- Data is from a single site with specific soil (alluvium/aeolian mix) and climate conditions, limiting geographic generalizability.
- Temporal recency of the data collection within the 25-year period is unspecified.
