A 20-year experiment from 1971 to 1992 in Ivory Coast provides crop yield and soil property data. The dataset contains results from 12 different treatments, each replicated 8 times, combining mineral nitrogen fertilizer and compost additions. It was created by researchers from CIRAD and others for the study 'Sustaining maize yields and soil carbon following land clearing in the forest–savannah transition zone of West Africa'.
Use Cases
- Modeling maize yield response based on fertilizer and compost application rates.
- Analyzing soil organic carbon stock dynamics over a 20-year period.
- Comparing soil carbon fraction changes across different treatment combinations.
- Studying the sustainability of agricultural practices in the forest-savannah transition zone.
Strengths
- Data spans a 20-year experimental period (1971-1992).
- Includes 12 distinct treatments replicated 8 times.
- Combines crop yield, weather, and detailed soil property measurements.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic and temporal bias inherent to a single long-term experiment.
