Since 2001, this dataset contains carbon flux measurements from a rainfed maize-soybean rotation field near Mead, Nebraska. The site is managed under no-till practices and is part of a University of Nebraska Agricultural Research and Development Center study. The data is maintained by AmeriFlux and authored by Andy Suyker.
Use Cases
- Modeling carbon sequestration in rainfed agricultural systems based on long-term flux measurements.
- Comparing ecosystem productivity between irrigated and rainfed crop sites based on the site description.
- Analyzing the impact of no-till management on carbon fluxes over a multi-year period.
- Studying crop rotation effects on seasonal and annual carbon exchange patterns.
Strengths
- Long-term data collection initiated in 2001, providing over two decades of observations.
- Site is part of a controlled study with three nearby fields, allowing for comparative analysis.
- Specific management practices like no-till and a pre-2001 soil homogenization event are documented.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Last update date is unknown; freshness unverified.
