英文文献摘要：
As a consequence of the changing structure of livestock industries, many farmers lack the amount of land required to apply manure based on either nitrogen or phosphorus needs. Therefore, there is a need for non-livestock farms to use manure as an alternative to commercial fertilizers in order to efficiently utilize nutrients in manure without degrading water quality. However, few if any studies have examined whether or not crop farmers will in fact accept manure, nor do they examine the factors affecting acceptance. For these reasons, farmers in Missouri and Iowa were surveyed to identify the factors affecting crop farmers? acceptance of manure. Logit model results show that perceived profitability, uncertainty, awareness of other farmers using manure, age, and location to be significant factors affecting use of manure.

由于畜牧业结构的变化，许多农民缺乏根据氮或磷需求施用肥料所需的土地。因此，非牲畜农场需要使用粪肥作为商业肥料的替代品，以便在不影响水质的情况下有效利用粪肥中的养分。然而，几乎没有研究调查过农民是否真的接受粪肥，也没有研究过影响接受的因素。基于这些原因，我们对密苏里州和爱荷华州的农民进行了调查，以确定影响农?接受粪便。Logit模型结果显示，感知盈利能力、不确定性、其他农户使用粪肥的意识、年龄和地点是影响粪肥使用的重要因素。
