Nitrogen and phosphorus are essential ingredients in fertilizers used to produce food. Novel methods are emerging for more efficiently sourcing these nutrients, one of which is to recover them from recycled human urine; once recovered, N and P can be redirected to fertilizer production. While the technology for creating human urine-derived fertilizer (HUDF) exists, implementing it at scale will depend on public acceptance. Thus, this study examined U.S. consumers' acceptance of HUDF across a range of applications and, in comparison, to other fertilizer types. Data were collected from a representative national sample, and analyses of variance with post-hoc comparisons were conducted to compare across fertilizer applications and types. A hierarchical regression was conducted to assess if demographics, psychological variables, and value orientations predict HUDF acceptance. Results suggest that HUDF and biosolid-based fertilizers are equally preferred and more strongly preferred than synthetic fertilizers. HUDF is not preferred as strongly as organic fertilizers. HUDF was deemed most acceptable when used on nonedible plants and least acceptable when used on crops for human consumption. Regression analysis revealed that judgments about risks and benefits were the strongest predictors of acceptance of UDF use. These results are promising for sanitation practitioners and regulators among others.

消费者对源自转移和回收的人类尿液的农业肥料的接受程度。

氮和磷是用于生产食物的肥料中的重要成分。正在出现新的方法来更有效地获取这些营养素，其中之一是从回收的人类尿液中回收它们。氮和磷一经回收，便可以重新用于化肥生产。虽然存在用于创建人类尿液衍生肥料（HUDF）的技术，但大规模实施该技术将取决于公众的接受程度。因此，本研究调查了美国消费者对HUDF在各种应用中的接受程度，并与其他肥料类型进行了比较。从代表性的国家样本中收集数据，并通过事后比较进行方差分析，以比较肥料的使用和类型。进行了层次回归分析，以评估人口统计学，心理变量，价值取向可预测HUDF的接受程度。结果表明，与合成肥料相比，HUDF和基于生物固体的肥料同样受到青睐，并且更受青睐。HUDF不如有机肥料那么可取。HUDF在非食用植物上使用时被认为是最可接受的，而在人类食用的作物上使用时则被认为是最不可接受的。回归分析显示，对风险和收益的判断是接受UDF的最强有力的预测指标。这些结果对于卫生从业者和监管者而言是有希望的。HUDF在非食用植物上使用时被认为是最可接受的，而在人类食用的作物上使用时则被认为是最不可接受的。回归分析显示，对风险和收益的判断是接受UDF的最强有力的预测指标。这些结果对于卫生从业者和监管者而言是有希望的。HUDF在非食用植物上使用时被认为是最可接受的，而在人类食用的作物上使用时则被认为是最不可接受的。回归分析显示，对风险和收益的判断是接受UDF的最强有力的预测指标。这些结果对于卫生从业人员和监管者来说是有希望的。
