Hermetia illucens L., known as Black Soldier Fly (BSF) appear an opportunity to reuse vegetable by-products, it is easy reproduce and can be reared in agricultural side streams, allowing the production of both, animal feed (the larvae, after recycling vegetal debris) soil organic fertilizer (insect frass). Although several fertilizers, from long ago, have been used agriculture, there yet a paucity experimental data on evaluation fertilization potential BSF larvae frass (BSFF). The present study contribution access agronomic environmental BSFF fertilizer. Within this aim, was conducted greenhouse experiment with ryegrass, using seven treatments BSFF. Under conditions, results showed significant effect overall ryegrass production, steady increase (significant at p ≤ 0.05, accessed through Tukey test) up treatment greater rate application. In what concerns sustainability productivity, end experiment, also positive indications, namely, OM, P K, for higher N endowments, together constant dehydrogenase activity, control treatment, which receiving dose
