镁（Mg）对动物健康至关重要。低镁状态（低镁血症）对牛羊等反刍动物可能是致命的，并且在欧洲广泛存在，对农业产生经济影响。应用富含镁的农业石灰产品可以帮助确保动物消耗的牧草含有足够的镁，并且在低pH值地区，具有将土壤酸度降低到最适合草生产的水平的双重好处。本研究的目的是确定富镁石灰产品是否可以更有效地用于农业生产系统。利用英国地质调查局（BGS）的数据集，确定了英国碳酸盐岩（石灰岩、白云岩和白垩岩）的潜在资源及其Mg:Ca状态。这些数据与农业石灰采石场的位置以及土壤可能缺乏镁和/或需要石灰的地区相结合。对富含镁的农业石灰有潜在需求的地区包括威尔士东南部、中部地区和英格兰东北部。虽然，这可能是一个有效的解决低土壤镁值的地区是受限制的适当产品的可用性。相反，在英格兰和威尔士，土壤pH值低的地区往往靠近采石场，有能力提供高钙石灰，这表明石灰的低使用率和石灰化不是由于供应因素。本研究提供的信息可以帮助指导农场决策利用富镁和其他石灰资源。这可以与其他选择结合使用，以减少牲畜缺镁的风险，并改善土壤pH值。
Magnesium (Mg) is essential for animal health. Low Mg status (hypomagnesaemia) can be potentially fatal in ruminants, like cattle and sheep, and is widespread in Europe with economic impacts on farming. The application of Mg-rich agricultural lime products can help to ensure pasture forage consumed by animals contains sufficient Mg and, in areas of low pH, has the dual benefit of reducing soil acidity to levels best suited for grass production. This aim of this study was to determine if Mg-rich lime products could be used in a more effective manner in agricultural production systems. Potential resources of carbonate rocks (limestone, dolostone and chalk) in the UK, and their Mg:Ca status were identified, using datasets from the British Geological Survey (BGS). These data were combined with the locations of agricultural lime quarries, and areas where soils are likely to be deficient in Mg and/or require liming. Areas of potential demand for Mg-rich agricultural lime include areas in south east Wales, the Midlands and North East England. Although, areas where this may be an effective solution to low soil Mg values are restricted by the availability of suitable products. Conversely, areas of low soil pH in England and Wales are often found close to quarries with the ability to supply high Ca limes, suggesting that the low rates of lime use and liming is not due to supply factors. This study provides information that can help to guide on-farm decision making for use of Mg-rich and other lime resources. This could be used in conjunction with other options to reduce risks of Mg deficiency in livestock, and improve soil pH.
