Estimates of manure volumes by livestock type and land use for England and Wales

Estimates of annual volumes of manure produced by six broad farm livestock types for England and Wales at 10 km resolution, modelled with MANURES-GIS [1]. The farm livestock classes are: dairy cattle; beef cattle; pigs; sheep and other livestock; laying hens; broilers and other poultry. The quantities produced by each type are subsequently apportioned into managed and field-deposited manure. The managed manure sources are categorised as beef farmyard manure, beef slurry, dairy farmyard manure, dairy slurry, broiler litter, layer manure, pig farmyard manure, pig slurry and sheep farmyard manure. The destinations are recorded as grass, winter arable, spring arable and direct excreta when grazing. For each 10 km square, the quantity of manure going from each source to each destination is estimated. The values specify amount of excreta, in kilograms for solid manure and in litres for liquid manure.

本数据集以10公里分辨率为基准，对英格兰和威尔士六种主要农业畜牧业类型产生的年度粪便体积进行了估算，数据模型采用MANURES-GIS [1]。具体畜牧业类别包括：乳牛；肉牛；猪；羊及其他牲畜；产蛋鸡；肉鸡及其他家禽。各类牲畜产生的粪便量随后被分配至管理型粪便和田间堆放粪便。管理型粪便来源被划分为牛肉农场粪便、牛肉污水、乳牛农场粪便、乳牛污水、肉鸡粪便、产蛋鸡粪便、猪农场粪便、猪污水和羊农场粪便。粪便的去向记录为草地、冬季谷物田、春季谷物田以及放牧时的直接排泄物。对于每个10公里网格单元，估算每个来源到每个去向的粪便量。数值指定了排泄物的量，对于固态粪便以千克为单位，对于液态粪便以升为单位。[1] ADAS（2008）《国家畜牧业粪便负荷清单及地图》：MANURES-GIS。Defra项目WQ0103最终报告。关于此数据集的详细信息，请参阅https://doi.org/10.5285/517717f7-d044-42cf-a332-a257e0e80b5c。
