Input to Yield Ratio (IYR) maps for wheat farming in England, 2010-2017

These maps show the Input to Yield Ratio (IYR) of wheat farming in England, calculated as the ratio of agrochemical inputs to agricultural reward as yield. We assess the IYR at a 1km resolution for wheat grown in England over the period the period 2010-2017, considering the different agrochemicals used and their differing forms of environmental impact. We provide four mapped products: IYR for Nitrogen fertilisers, IYR for Phosphorus fertilisers, IYR for pesticide risk to earthworms, and IYR for pesticide risk to honeybees. The IYR is calculated using scaled rather than absolute values, with the maximum value in each yield and inputs dataset set as 1, so that all inputs and rewards are expressed proportionally to each other. The research was funded under research programme NE/N018125/1 ASSIST and NE/W005050/1 AgZero+.

本组地图展示了英格兰小麦种植的投入产出比（IYR），该比值为农业化学品投入与农业收益（产量）之比。本研究以1公里分辨率为基准，对2010-2017年间英格兰种植的小麦的IYR进行了评估，考虑了不同农业化学品的使用及其对环境的不同影响形式。我们提供了四种映射产品：氮肥的IYR、磷肥的IYR、对蚯蚓的农药风险IYR以及对蜜蜂的农药风险IYR。IYR的计算采用比例值而非绝对值，每个产量和投入数据集中的最大值设为1，以确保所有投入和收益均以相互比例的形式表达。本研究由研究项目NE/N018125/1 ASSIST和NE/W005050/1 AgZero+资助。关于本数据集的详细信息，请参阅https://doi.org/10.5285/dfe2a4a5-2b3a-4731-ba7f-aea7e926f1dd。
