A significant proportion of agricultural land in Europe is grass for livestock grazing. For example, in the UK as a whole, the combined area of grassland is around 6,997,000 hectares, nearly 38% of the total agricultural area [2]. In Northern
Ireland, where clay soils and a temperate climate are particularly suitable for grass production, this percentage is much higher. Here about 95% of farmland is devoted to the production of grass for cattle and sheep. This has helped Northern Ireland develop as a center of excellence for grassland management research. This article focuses on agricultural pollution caused by the over-application of phosphate to grassland, using the example of Northern Ireland
as a case study. The use of X-ray fluorescence (XRF) spectrometry to measure the phosphorus content of grass is also highlighted.
