| Abstract | Given the current rate of human population growth, the mass breeding of insects for feed and food is in full industrial development, as a more efficient and effective alternative to conventional livestock for the production of animal protein. In these industries, the production of insect excreta (frass) represents one of the main outputs of the process, being up to 40 times greater than the production of animal biomass, which is why its use as organic fertilizer to replace the use of agrochemicals is considered a viable alternative in the development of sustainable agriculture and a circular economy. Through a review of all the existing literature, this article highlights the following benefits of the use of insect frass as organic fertilizer in sustainable agriculture: (1) contribution of nutrients to the soil, mainly nitrogen, easily assimilated by plant tissues; (2) addition of biomolecules and microorganisms that promote plant growth; and (3) increased tolerance to abiotic stresses and resistance to pathogens and pests due to the presence of different compounds and microorganisms. Therefore, insect frass from the mass breeding of insects for feed and food represents an important source of effective organic fertilizer for use in sustainable agriculture. |
