Other insect frass uses include fertilizing with nutrients in low, easy-to-uptake doses. Chitin helps plants to know and boost their defense by building their cell walls and releasing toxins.

For this reason, you don't have to worry about frass killing beneficial insects or nematodes.

Due to its rapid mineralization and the presence of nutrient in a readily-available form, we found that frass is as efficient as mineral NPK fertilizer to improve biomass and N, P and K uptake by barley.

The available K and P concentrations when 50% of the NPK were substituted by 50% frass (50NPK/50Frass treatment) were similar and lower, respectively, than when NPK is used alone but higher compared to the complete NPK substitution by frass. Plus, it encourages root growth and expansion and helps with soil moisture levels.

It contains digested plant material that an insect has excreted. The frass also acts as an organic pesticide by deterring gnats, grubs, and root-feeding nematodes, and is a fungal inoculant stimulating the growth of mycorrhizal fungi in the soil. 32 showed that, although organic amendments increased AWCD at both 10 and 20 Mg ha−1 application rate, S index was only improved in the 20 Mg ha−1 treatment due to higher C availability for microorganisms. In European Union, novel food regulation 2015/2283 (in application since 1st January 2018) clarified the legal status of insects and their derived products. IUSS Working Group WRB. Kahiluoto, H., Kuisma, M., Ketoja, E., Salo, T. Insect Frass vs Worm Castings - Which is Better. & Heikkinen, J. Phosphorus in manure and sewage sludge more recyclable than in soluble inorganic fertilizer. They are mainly incorporated into the soil but can serve as a top dressing. So considering the time versus money benefit is important when making this decision.
Insect Frass Vs Worm Castings Definition
In addition to be an alternative source of proteins for humans and animals, insect farming has also been considered to produce biofuel, some rare lipids and chitin, which has a great economical value due to its application in food, cosmetics, pharmaceuticals, textile etc. This study indicates that frass has a great potential to be used as a partial or a complete substitute of mineral NPK fertilizer. One of the best things about compost is that you can make it yourself by simply dumping vegetables, plant trimmings, grass, and other organic material into a pile. If you have extra you can store it in the fridge for up to a week. Doublet, J., Francou, C., Poitrenaud, M. & Houot, S. Influence of bulking agents on organic matter evolution during sewage sludge composting; consequences on compost organic matter stability and N availability. Continue reading down below to see what each of these are, how they are used, and a comparison of their characteristics. This means it is 5% nitrogen, 3% phosphorus, and 2% calcium.

"Chitosan is a one of the most abundant natural amino polysaccharides extracted from the exoskeleton of crustaceans and insect, from fungal cell walls". A laboratory experiment. Indeed, Gomez et al.
Thus, causing them to rev up and defend themselves against predators like root-feeding nematodes and disease pathogens in the soil. Since the functioning of ecosystems strongly relies on soil biodiversity 35, 36, the added benefits resulting from the combined use of frass and NPK on soil microbial functional diversity suggests that a partial substitution of mineral fertilizer by frass could be an enticing option for the sustainable management of agroecosystems.
