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
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.
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.
It should be noted that compost and farmyard manure are rich in nutrients and that the application of compost and farmyard manure should be done judiciously to limit additional nitrogen and phosphorus leaching.
The goal: to reduce weed and disease pressure in the crops and to achieve good, high-quality yields based on customized provision of oxygen and water, a good utilization of nutrients such as nitrogen and phosphorus, and good soil management and root penetration.
