Thirteen swine producers from Corn Belt states participated in a project with faculty from University of Nebraska and Purdue University to understand the movement of nutrients (nitrogen and phohsphorus) on commercial swine facilities. These farms ranged in size from 2,000 to 16,000 head finishing capacity with most farms being wean to finish or feeder pig to finish operations. The project team developed a whole farm nutrient balance for each farm for both 2006 and 2007 based upon farm specific data.
Primary project outcomes include an understanding of the primary sources of nutrients arriving on these farms, the magnitude of imbalances experience by these farms, and the value of specific nutrient management practices to minimizing the nutrient imbalances experienced by swine production.
To learn more about the concept of Whole Farm Nutrient Balance (WFNB), the lessons learned from this on-farm research, and the tools developed for use by producers, the following introduction is suggested:
