Thematic network on reuse of nitrogen and phosphorus (NUTRIMAN)
Getting technologies, products and practices for reuse of nitrogen and phosphorus to farmers is the goal of the European project NUTRIMAN.

Main research questionNUTRIMAN is a Nitrogen and Phosphorus Thematic network on nitrogen (N) and phosphorus (P) that compiles knowledge of “ready-for-practice” bio-based fertiliser products based on recovered N and P. Applied science and industrial practices are linked for the interest and benefit of the farmer.
Efforts will always be made to limit nitrogen and phosphorus excetions and emissions to the environment in an economical way.Research approachThrough 3 ILVO animal trials and 7 specific cases on practicing farms, protein saving strategies will be evaluated for animal performance, production, protein savings, feed efficiency, cost efficiency and environmental
Main research questionHow do we achieve reduced nitrate nitrogen and phosphorus leaching, better control of nitrogen losses from ammonia volatilization, and lower greenhouse gas emissions from the agricultural sector, both plant and animal production?
A better feed and nutrient efficiency will also minimize losses of phosphorus and nitrogen to the environment. The results will be primarily applicable to pig farmers, but they are also useful for consultants, genetics companies, technology companies, feed manufacturers, slaughterhouses and the processing industry.FinancingVLAIO
The researchers also conducted a consumer study in 6 European countries on how immunocastration is perceived.Relevance/ValorizationThe results of this project confirm that immunocastrates are a clearly more sustainable ecological alternative compared to keeping surgically castrated male piglets, both in terms of nitrogen and phosphorus emissions and
Cuttings from nature reserves and roadsides generally contain little phosphorus in relation to organic carbon and are therefore interesting for increasing the carbon content of a soil with a limited risk of phosphorus loss. They also bring valuable nutrients and stimulate soil biology.
to limit nitrate losses: Right dose: a dose that does not cause unnecessary nitrogen losses, but is sufficient for optimal crop yield;Right fertilizer type: choice of fertilizer type or fertilizer that best meets the needs of the crop and is compatible with soil properties;Right timing: fertilize at the time when the plant needs the nitrogen (and phosphorus
