An organic fertilizer
The experiment at Länsiharju school is finished. Children and the teacher feed most of the larvae to teacher colleague’s chickens and to the Vesijärvi fishes. Less than 100 larvae were bred from larvae up to black soldier flies.
The fourth fraction which is a result of the experiment is a glass bin full of organic fertilizer which is a composition of composted food, peat which was used as a bed of larvae and larvae poo. I will use this fertilizer in the garden in spring 2021.
