This article discusses the situation in the Netherlands with a primary focus on swine. Some nutritional means may have relevance to North America.

This manure tends to be high in minerals, which has had negative effects on soil, water and air quality. In current legislation, phosphate has been used to quantify manure production. This has given producers an incentive to reduce total manure volume by increasing its dry matter content. The use of heavy mineral growth promoters has already been abolished for years.
