Drier土壤捕捉更多磷,农场径流造成的水污染加剧,新的研究显示。 Drier soils trap more phosphorus, worsening water pollution from farm runoff, new research shows.

数十年肥料使用产生的过量磷正在污染美国水道,为有害的藻类繁殖和像墨西哥湾那样的死亡区火上浇油。 Excess phosphorus from decades of fertilizer use is polluting U.S. waterways, fueling harmful algal blooms and dead zones like the one in the Gulf of Mexico. 磷虽然不易浸出,但会通过土壤侵蚀和径流,损害生态系统和饮用水。 While phosphorus doesn’t leach easily, it moves via soil erosion and runoff, harming ecosystems and drinking water. 新的研究表明,土壤湿度,而不仅仅是肥料,决定磷是积聚还是耗竭,而干燥的土壤积累得更多。 New research shows soil moisture, not just fertilizer, determines whether phosphorus builds up or depletes, with drier soils accumulating more. 作物类型和气候变化等因素进一步影响结果,突出表明需要量身定制的、以科学为基础的管理,以减少污染和维持农业生产力。 Factors like crop type and climate change further influence outcomes, highlighting the need for tailored, science-based management to reduce pollution and maintain farm productivity.
