Note to Reader concerning Phosphorous Redistribution Projects

In order to comply with current provincial manure management regulations, livestock producers in phosphorus surplus areas of Manitoba have to implement ways to redistribute nutrients to phosphorus deficient areas. The Manitoba Livestock Manure Management Initiative (MLMMI) is undertaking a series of projects to find effective affordable solutions for producers. This report is one of these projects.

All options available to producers in phosphorus surplus areas are under consideration. These include but are not limited to manure separation, manure handling and storage, and liquid manure transportation. This report is only one of many options that are under consideration.

Its been proven that gravitational settling will cause the P rich solids in liquid manure to settle to the bottom of the slurry in an earthen manure storage or vessel. This project consisted of a review of literature; an analysis of data in the literature; and the development of conceptual method to use gravity separation systems. It includes conceptual designs.


Final Report

Manitoba Pork represents 614 Manitoba hog farms
