Black Soldier fly (Hermetia illucens) larval (BSFL) frass separated from BSFL processed catering waste, and that recovered directly from larvae, was examined for its nitrogen, phosphate and potassium (N:P205:K2O), phytohormone and biogenic amine content, its plant growth promoting activity, and screened to test the hypothesis that bacteria characte...

... recovered from BSFL processed catering waste applied to potting soil nevertheless accelerated the growth of winter wheat berry seedlings planted in the potting soil. Table 2 contrasts the growth of potted winter wheat berry seedlings grown in potting soil amended with frass to that of control seedlings grown in potting soil unexposed to frass. The results show that frass, though very low in nutrient (N:P205:K2O), biogenic amine and phytochrome content, enhances the growth of seedlings grown in soil treated with frass as evidenced by an average 11% increase in total upper plant mass relative to that observed for seedlings grown in control (untreated) soil concomitant with a statistically significant 11% increase in the average shoot length of the plants. ...Context 2

These latter results make it very unlikely that the plant growth promoting activity reported here on amending frass into soil ( Table 2) is attributable to its N:P205:K2O, biogenic amine and/or phytohormone content. ...Context 3

Hermetia illucens has received a lot of attention as its larval stage can grow on organic substrates, even those that are decomposing. Black soldier fly breeding provides a variety of valuable products, including frass, a mixture of larval excrements, larval exuviae, and leftover feedstock, that can be used as a fertilizer in agriculture. Organic fertilizers, such as frass, bringing beneficial bacteria and organic materials into the soil, improves its health and fertility. This comprehensive review delves into a comparative analysis of frass derived from larvae fed on different substrates. The composition of micro- and macro-nutrients, pH levels, organic matter content, electrical conductivity, moisture levels, and the proportion of dry matter are under consideration. The effect of different feeding substrates on the presence of potentially beneficial bacteria for plant growth within the frass is also reported. A critical feature examined in this review is the post-application beneficial impacts of frass on crops, highlighting the agricultural benefits and drawbacks of introducing Hermetia illucens frass into cultivation operations. One notable feature of this review is the categorization of the crops studied into distinct groups, which is useful to simplify comparisons in future research.
