Insect-derived byproducts as amendments in specialty crop production

Urban farmers face several challenges, including low-quality soil in urban spaces. A common approach currently implemented involves the application of amendments, which can be derived from various processes such as aerobic or anaerobic composting, manure, insect-derived waste from protein production facilities, and composting with insects. Some of the most promising amendments include composting with black soldier flies (Hermetia illucens; BSF) and recycling waste from cricket production facilities. The advantages of utilizing amendments include improving soil fertility, increasing water hold capacity, and stimulating soil microbial community. This study aimed to assess the application of three insect-derived soil amendments on specialty crop production. Through field experiments, we evaluated the effects of the three insect-derived soil amendments on yield in two cropping systems: carrots and bok choy. Additionally, we assessed the impact of the three insect-derived soil amendments on soil health metrics, particularly soil aggregate stability, bulk density, and microbial activity. The findings of this study will provide valuable insights into the application of insect-derived amendments and enhance soil health in urban agriculture.
