The global shift toward eco-farming has made insect-based fertilizers a key solution for reducing synthetic input reliance. Sourced from insect excreta and dried insect biomass, they deliver nutrients naturally and sustainably. These fertilizers improve microbial activity and nutrient absorption while helping restore degraded soils. Urban farms, indoor grow systems, and outdoor agricultural setups all benefit from their use. Their production supports circular food systems by converting organic waste into useful inputs. Market growth is bolstered by rising food demand and awareness of environmental protection. As agriculture evolves, insect-based fertilizers stand out as both efficient and planet-friendly.
