Insect frass fertilizer as soil amendment for improved forage and soil health in circular systems [PDF]

Scientific Reports
Insect farming is expected to increase in coming years, thus generating high quantities of frass (insect excreta). Frass valorization hinges on basic agronomic research prior to industry upscaling.

Evolving dynamics of insect frass fertilizer for sustainable nematode management and potato production. [PDF]

Front Plant Sci
Potato production faces major challenges from inadequate soil fertility, and nematode infestation, yet synthetic fertilizers and nematicides are costly and harmful to the environment. This study explored the potential of chitin-fortified black soldier fly-composted organic fertilizer (BSFCOF) as a multipurpose organic fertilizer amendment for enhancing

Insect frass composition and potential use as an organic fertilizer in circular economies. [PDF]

J Econ Entomol
Abstract Insect manure or “frass” has emerged as an alternative nutrient source for alleviating the dependence on fossil fuel-based fertilizers, reducing food waste, and promoting food security. Yet, research on insect frass chemical composition is in its infancy.

Insect frass in Baltic amber [PDF]

Bulletin of the Geological Society of Finland, 2008
Inclusions of wood debris loosened from pine-like trees are abundant in Baltic amber of Eocene and Oligocene age. The possibilities to find insect frass and excrement among wood debris are outlined and some examples are given.

Linking frass and insect phenology to optimize annual forest defoliation estimation

MethodsX, 2023
It is often logistically impractical to measure forest defoliation events in the field due to seasonal variability in larval feeding phenology (e.g., start, peak, and end) in any given year.

Mathematical and computational modeling for organic and insect frass fertilizer production: A systematic review. [PDF]

PLoS One
Organic fertilizers have been identified as a sustainable agricultural practice that can enhance productivity and reduce environmental impact. Recently, the European Union defined and accepted insect frass as an innovative and emerging organic fertilizer.

Effects of applying locust frass on the soil properties and microbial community in a peach orchard [PDF]

Microbiology Spectrum
Insect frass, a by-product of insect cultivation, represents an emergent category of agricultural waste. How to develop and make full use of this waste is a major issue to be addressed.

Mealworm frass fed on expanded polystyrene helps retention of chrysanthemum flower [PDF]

Scientific Reports
Insect frass is being considered as a source of crop fertilizer. However, previous studies have focused on the growth and yield of vegetables but have not conducted on flower performance much.
