“…In future EFs should be related to the most important parameters which should include the transformation of organic N to TAN. Emission from applied slurry is calculated using standard European conditions and is related to slurry DM and application rate, rain intensity and temperature (Hafner et al, 2018;Huijsmans et al, 2018). Soil characteristics will in practice have an effect on emissions (Chantigny et al, 2004;Seçer et al, 2018), but the statistical model does not include soil characteristics, because there was no clear effect of soil type in the analyses of emission data from the 12 countries that provided data for the model, which were from south to north of Europe (Hafner et al, 2018).…”

“…So, one might argue that, for the 160 experiments discussed in this paper, the choice of a particular wind speed model is a matter of taste. This does, however, not imply that grass height is unimportant; a higher canopy has a reducing effect on the emission in case of narrowband and shallow injection (Huijsmans et al., ; Huijsmans, Vermeulen, Hol, & Goedhart, ; Thorman, Hansen, Misselbrook, & Sommer, ).…”

The integrated horizontal flux method is commonly used to estimate ammonia emission from field‐applied manure. The method involves measuring the wind speed and ammonia concentration at various heights on a post in the middle of a manured plot. Wind speed and concentration profiles are subsequently fitted to these measurements. The product of the profiles represents the amount of ammonia displaced by the wind, and the calculated ammonia emission is based on integrating the product of the profiles along the height. A crucial step is the functional form of the profiles, and linear relationships employing the logarithm of the height are generally used. In this study, 160 Dutch emission experiments on grassland were re‐analysed to evaluate alternative profiles for the concentration and wind speed. It is shown that an exponential concentration model usually provides a better fit than the commonly used profile and that the measurement error for the concentration should be modelled by means of a gamma distribution. Based on the re‐analysis, this new model reduces the calculated ammonia emission by around 10%. It is further shown that adding a displacement parameter to the wind speed model only has a minor effect on the calculated emission. Finally, a simulation study reveals that misspecification of the concentration profile may lead to a relative bias of up to 27%, that the precision of the estimated emission can be improved by increasing the number of concentration measurements near the ground and that wind speed measurements at three heights could suffice.

“…Hierbij zijn wel logistieke problemen te verwachten. Er komen minder beschikbare dagen per jaar om mest aan te wenden en op de meest gunstige dagen zullen loonwerkers niet voldoende capaciteit hebben om alle klanten te kunnen bedienen (Huijsmans et al, 2018). Niettemin is bewustwording op dit vlak een relevante stap.…”

“…temperatuur is de ammoniakemissie lager dan bij hoge temperatuur(zie ook Figuur 7;Huijsmans et al, 2018). Figuur 7 is het resultaat van berekeningen met een model dat rekening houdt met weersomstandigheden; de doorgetrokken lijn geeft de ammoniakemissie weer voor 'gemiddeld' weer op de 15 e voor elke maand (gemiddeld over 24 jaar KNMI weersgegevens).Bewolkt, regenachtig en relatief koel weer is dus optimaal voor mestaanwending.…”
