Soil Properties and Crop Yield Response to Insect Frass Fertilizer in Madagascar

A field experiment dataset quantifying maize and soybean yield responses to Black Soldier Fly frass fertilizer application in northern Madagascar. The dataset likely contains soil properties and crop yield measurements from rates ranging from 0 to 30 t ha⁻¹. The data was authored by Tanjona Ramiadantsoa and last updated on May 4, 2026.

Use Cases

• Modeling crop yield response curves based on fertilizer application rates described in the experiment.
• Conducting economic analysis of fertilizer profitability based on the marginal value–cost ratio (MVCR) framework mentioned.
• Comparing organic and inorganic fertilizer performance based on the price comparison to NPK fertilizer discussed.
• Assessing sustainable intensification pathways for maize and soybean systems in low-yield regions as described.

Strengths

• Data is derived from a large-scale field experiment with specific application rates from 0 to 30 t ha⁻¹.
• Results indicate yield increases up to 12-fold for maize and 1.7-fold for soybean relative to controls.
• Includes an economic analysis component with specific price points (e.g., USD 13.8 t⁻¹) and MVCR calculations.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small (5.5 KB), suggesting limited scope or a summary of results.
