农场的氮素养分滋养了全球，但这一过程对我们的水源造成了严重影响。缓冲区是自然防止营养物质污染的重要“保护线”。有效管理这些缓冲区可以提升对自然生态系统及人类健康的保护。农民可以利用 Patch 经济高效的测试系统来监测和降低农场的硝酸盐含量，从而提高径流水质，促进生物多样性；同时，Patch 还鼓励农民根据自己土地的风险情况采用有益的地方管理计划。

Nitrogen on farms supports global food production but significantly harms our waterways. Buffers act as “nature’s last stand” against nutrient pollution, and effective management enhances their positive impact on ecosystems and human health. Farmers can enhance water quality in their runoff and promote biodiversity by utilizing Patch’s cost-effective testing system to monitor and mitigate nitrate levels on their farms, while also encouraging the adoption of beneficial local stewardship schemes tailored to their land’s risk situation.
