Guanology™: Data-Driven Organic Fertility
Guanology is our integrated engine that turns bat guano into predictable performance: a biotech lab that standardizes and enhances nutrient profiles, and a AI App that translates soil data and weather into precise, field-ready recommendations. Every lot is tested, traced cave→batch→farm, then matched to crop stage and local soils for optimal dose and timing. Farmers see what matters—clean inputs, consistent N-P-K (±0.5%), slower release when needed, and measurable yield gains—while distributors get digital traceability, QA reports, and multi-season plans. Guanology closes the loop: product science, agronomic intelligence, and on-farm proof, all in one system.
Guanova revolutionized our farming with its top-notch organic fertilizers! Our yields have increased significantly, and we’ve noticed healthier crops. Plus, it feels good to support a company dedicated to sustainable agriculture in Madagascar.

ESG at Guanova: Impact you can verify
We turn ESG into execution. Community MOUs set quotas and non-intervention windows, with 30% cave sanctuaries and QR traceability from cave to client. We fund €10k/year to an NGO for bat and cave monitoring and allocate 3% of net profits to the SAKAFO-FAHENDRENA fund (food & education). Collection teams are salaried, HSE-trained, and paid cashless under KYC/anti-corruption rules. Processing in Antananarivo runs HACCP/QA with lot release, while GUANOLOGY (lab + SaaS) optimizes doses to lift yields and cut runoff. We prioritize women and youth hiring, enable access via Baobab microcredit, and plant trees per ton sold. Annual ESG KPIs, third-party audits, and certifications in progress (EU Organic, JAS, KOC, USDA) keep every claim accountable.
