Summary
This study was initiated to better understand the changing composition of manure samples within a storage and between different liquid swine manure storages used in Manitoba. In a recent study done by Fitzgerald and Racz, 2001, various storages across Manitoba were sampled and analyzed. This study found large variations between hog type (finisher, nursery, sow) and at different levels in the storage. (top, middle, or bottom) It is well known that stratification, settling of solids, occurs in all types of storages and when agitated the solids are mixed back into the liquids. This project will look at a single-cell, two-cell, and a circular storage system during a typical application and characterize the nutrient composition.
