Composed of frass and insect matter, these fertilizers supply balanced nutrients without the risks linked to chemicals. They encourage biodiversity in the soil and improve water efficiency. Adoption is rising in organic, smallholder, and specialty crop farming. The industry benefits from improved breeding and harvesting techniques in insect farming. Their odorless, lightweight form enhances ease of use. Governments promoting carbon-neutral agriculture support the sector’s expansion. With scalability and versatility, these fertilizers are becoming key to modern, resource-smart farming practices across a wide range of regions.
