Ref No. 46 Composting of manure with larvae of the housefly
Brief description Description of the effect on leaching (positive or negative) of N and P
A method for composting manure using the housefly larvae has been subject to resent
research at the University of Alicante. The aim for the project is to address 3 major
problems. 1. Overload of manure and nutrients in areas with dense livestock production.
2. Need for high quality protein feeding. 3. Odour emissions in relation to manure
management. Those three problems can all be met if the manure is composed by fly
larvae. More than half of the organic matter in the manure as well as the nutrients is
been transformed in to larvae, which later can be used as feeding ex. in fish farming.
The residue is at odour less dry compost, easy to distribute and apply.
Principally this technology can convert the main part of the N and P into flies,
which is used as a feed ingredient, and thus re-circulated in the agricultural
production, and eliminating the risk of being leached.
