Phosphate circularity: from dairy cow slurry to grassland agronomy

动物粪便富含营养物质，是一种有吸引力的可持续肥料，可以取代工业生产的肥料，帮助农业，特别是乳制品行业实现净零排放目标。不幸的是，在耕地上施用泥浆既耗时又对环境敏感。我们计划与奶农合作，重新设计他们如何使用与现有系统兼容的安全、经济、节能的技术来管理他们的浆液。我们的目标是帮助奶农以环境和经济可持续的方式使用他们的浆液，帮助回收植物生长所需的必需营养素，并利用他们的草原进行碳捕获。

Animal slurry is rich in fertiliser nutrients and an attractive sustainable fertiliser replacing industrially produced ones to help agriculture, particularly the dairy sector, achieve its net-zero targets for emissions. Unfortunately, application of slurry to farmed land is time-consuming and environmentally sensitive. We plan to work with dairy farmers to re-design how they manage their slurry using safe, affordable and energy efficient technologies that are compatible with their existing systems. We aim to help dairy farmers use their slurry in an environmentally and economically sustainable way, helping to recycle essential nutrients for plant growth and use their grasslands for carbon capture.
