A Whole-Farm Strategy to Reduce Environmental Impacts of Nitrogen (2008)

Sonneveld, M.P.W., Schröder, J.J., Monteny, G.J., Mosquera, J., Hol, J.M.G., ...

Dutch regulations for ammonia emission require farmers to inject slurry into the soil (shallow) or to apply it in narrow bands at the surface. For one commercial dairy farm in the Netherlands it was...

Gaseous emissions from a deep litter farming system for dairy cattle (2006)

Mosquera, J., Hol, J.M.G., Monteny, G.J.

Gaseous emissions (NH3, CH4, N2O, odor) were measured from a deep litter farming system for dairy cattle in the Netherlands (barn and outdoor manure storage). On average, 13.9 kg NH3 per cow were...

Ammonia emission and nutrient load in outdoor runs of laying hens (2006)

Aarnink, A.J.A., Hol, J.M.G., Beurskens, A.G.C.

Ammonia emission and nutrient load in outdoor runs of laying hens were measured at a commercial farm with an outdoor run for 3000 hens, and at an experimental farm with two outdoor runs, each for...

Ammoniakemissie en mineralenbelasting op de uitloop van leghennen (2005)

Aarnink, A.J.A., Hol, J.M.G., Beurskens, A.G.C., Wagemans, M.J.M.

Bescherming van het milieu is een belangrijke reden voor de overheid om biologische landbouw te promoten. Uitlopen van leghennen zouden echter een bron van ongewenste emissies kunnen zijn. De...

Improved passive flux samplers for measuring ammonia emissions from animal houses, part 1: Basic principles (2003)

Scholtens, R., Hol, J.M.G., Wagemans, M.J.M., Phillips, V.R.

At present, precise, expensive and laborious methods with a high resolution in time are needed, to determine ammonia emission rates from animal houses. The high costs for equipment, maintenance and...

Effect of application method, manure characteristics, weather and field conditions on ammonia volatilization from manure applied to arable land (2003)

Huijsmans, J.F.M., Hol, J.M.G., Vermeulen, G.D.

To predict ammonia (NH3) volatilization from field-applied manure, factors affecting volatilization following manure application need to be known. A database of field measurements in the Netherlands...

Onderzoek naar de ammoniak- en geuremissie van stallen LIX : welzijnsvriendelijk huisvestingssysteem voor dragende zeugen in kleine groepen (2003)

Wagemans, M.J.M., Hol, J.M.G., Groenestein, C.M.

Ammonia emission from animal husbandry has to be reduced in the Netherlands by 70% in the year 2005, compared with the emission level in 1980. Moreover, new odour legislation requires measurements of...

Ammoniakemissie op de Marke : Onderzoek en resultaten van 1994 tot 2001 (2003)

Koskamp, G.J., Kool, A., Middelkoop, N., Huijsmans, J.F.M., Hol, J.M.G., Smits, M.C.J., ...

Strenge doelstelling gehaald Voor ammoniak is de landelijke norm een reductie van 70% ten opzichte van 1980. Dit is in het Nationaal Milieubeleidsplan (NMP3) vastgelegd en door De Marke overgenomen....

Ammonia emission from individual- and group-housing systems for sows (2001)

Groenestein, C.M., Hol, J.M.G., Vermeer, H.M., Metz, J.H.M.

Given that freedom of movement improves sows’ welfare, the implications for the emission of ammonia of keeping sows in groups instead of individually were investigated. Three housing systems were...
