    'Staff publications' is the digital repository of Wageningen University & Research

    'Staff publications' contains references to publications authored by Wageningen University staff from 1976 onward.

    Publications authored by the staff of the Research Institutes are available from 1995 onwards.

    Full text documents are added when available. The database is updated daily and currently holds about 240,000 items, of which 72,000 in open access.

    We have a manual that explains all the features

Abstract Agricultural activities are in the Netherlands a major source of ammonia (NH3), nitrogen oxide (NO), nitrous oxide (N2O), methane (CH4) and particulate matter (PM10 and PM2.5). The emissions in 2016 were calculated using the National Emission Model for Agriculture (NEMA). Some figures in the time series 1990-2015 were revised. The method calculates the NH3 emission from livestock manure based on the total ammonia nitrogen (TAN) content in manure. In 2016 NH3 emissions from livestock manure, fertilizer and other sources in agriculture, from hobby farms, private parties and manure disposal in nature areas amounted to 116.8 million kg NH3, 1.3 million kg more than in 2015. Nitrogen excretion increased due to expansion of the dairy herd, but because of a larger share of low emission housing and more manure exports outside agriculture, the increase in NH3 emission remained limited. N2O emissions in 2016 were 21.1 million kg at virtually the same level as in 2015(21.2). NO emissions in 2016 totaled 22.8 million kg compared to 22.6 million kg in 2015. CH4 emissions increased from 496 to512 million kg due to the expansion of the dairy herd. Emissions of particulate matter PM10 and PM2.5, 6.5 and 0.6 million kg respectively, did not change compared to 2015. NH3 emissions from livestock manure in the Netherlands dropped by almost two thirds since 1990, mainly as a result of lower nitrogen excretion rates by livestock and low emission manure application. Emissions of N2O and NO also decreased over the same period, but less strongly (38% and 31% respectively), due to higher emissions from manure injection into the soil and the shift from poultry housing systems with liquid manure towards solid manure systems. CH4 emissions reduced by 13% between 1990 and 2016 caused by a decrease in livestock numbers and increased feed efficiency of dairy cattle.
