英文文献：Consequences Of Federal Manure Management Proposals: Cost To Swine Operations From Land Applying Manure-联邦粪肥管理建议的后果:土地施用粪肥给养猪业带来的成本
英文文献作者：Ribaudo, Marc,Agapoff, Jean,Gollehon, Noel R.,Aillery, Marcel P.
英文文献摘要：
A manure application cost model was used with survey data to examine the costs to confined swine operations of meeting proposed mandatory nutrient management plans across regions and size classes. Sector costs are examined under alternative scenarios involving nutrient standards, and owner willingness to accept, and the use of phytase.
在调查数据的基础上，采用粪肥施用成本模型来检验在不同地区和不同规模的猪群中，满足拟议的强制性营养管理计划所产生的成本。部门成本在涉及营养标准、所有者愿意接受和植酸酶的使用的替代方案下进行审查。
