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

Northern Madagascar field experiment data quantifying maize and soybean yield responses to Black Soldier Fly frass fertilizer. The dataset likely contains application rates from 0 to 30 t ha⁻¹ and corresponding dry grain yield measurements, resulting in up to 12-fold yield increases. Author Tanjona Ramiadantsoa published the 5.5 KB XLS file on figshare in May 2026.

Use Cases

• Modeling crop yield response curves based on frass fertilizer application rates.
• Conducting economic analysis of fertilizer profitability using marginal value–cost ratio (MVCR).
• Comparing the efficacy of organic insect-derived fertilizer to conventional NPK fertilizers.
• Assessing sustainable intensification pathways for maize and soybean systems in low-yield regions.

Strengths

• Data originates from a large-scale field experiment with defined application rates from 0 to 30 t ha⁻¹.
• Results show significant yield increases, with maize yields approaching a 12-fold increase over controls.
• Includes an economic analysis component with specific price points (e.g., USD 13.8 t⁻¹).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The 5.5 KB file size indicates a very limited data scope, likely summary results rather than raw observations.
