Nitrogen
The element nitrogen (N) is ubiquitous: 78% of the atmosphere is composed of nitrogen gas (N2) and it is a building block of all life on earth. No wonder it is an essential element in plant fertilizer...

Broilers that grow just as well but emit less nitrogen
The best nitrogen-reducing measure is source-oriented. That was the basic premise of the doctoral study performed by Madri Brink (ILVO-UGent- Proefbedrijf Pluimveehouderij). Her trials with broiler ch...
Feeding strategies are an important key to nitrogen-efficient dairy farming
Dairy farmers can reduce their nitrogen emissions by switching to grass-clover in combination with reduced nitrogen fertilization and mowing practices that improve grass silage quality. Reducing prote...
True measurement of volatile nitrogen from animal housing, is that (almost) possible?
The nitrogen emissions that dissipate under the form of ammonia from a barn with chickens, dairy cattle, beef cattle or pigs are now determined with a prediction model, based on a fixed emission facto...
