In Iowa, the release of confinement swine odors and manure nutrients into the environment has become an important issue. The objective of this paper is to measure the net benefit of using swine manure in alternative production systems. Net benefit is calculated for two storage technologies, two target nutrients, two crop rotations, and two levels of field incorporation after application. This investigation shows that applications based on phosphorus can better match crop nutrient need, and thereby lead to higher profits.
