Nitrogen reduction in fertilizer by insects

Nitrogen reduction in fertilizer by insects

The current nitrogen policy is causing panic. Livestock farming is under attack and construction projects have come to a standstill. Livestock farming contributes to the emission of ammonia and nitrogen oxide via the manure. Insects can probably be used to reduce nitrogen in the manure and thus reduce the emission of ammonia and nitrogen oxide.

Larvae of the black soldier fly (Blacksoldierfly) can develop on dung. They need nitrogen for growth and development. By growing them on manure, the amount of nitrogen in manure will decrease and the volume of the manure will decrease.

This research investigates how larvae can develop on different types of manure (chicken, cow, pig) and which larval density is optimal to reduce nitrogen as much as possible. The results will be shared with the Ministry of Agriculture, Nature and Food Safety.
