History of the La Broquerie Pasture and Manure Management Study
Expansion in the hog sector has created opportunities for both the beef and dairy cattle industries to economically improve forage productivity through the application of hog manure.
Although the application of hog manure may be mutually beneficial to hog and cattle producers, there are still many aspects of this practice that require further study. These include productivity of the forage land and the animals, soil and water quality, as well as greenhouse gas production.
To address some of these questions, a research and extension site was established in the Rural Municipality of La Broquerie in Southeast Manitoba (SE20 -5-8E) in September 2003. This is an area which is characterized by high livestock density, possessing more that 129 animal units/km2 – the 6th most livestock dense region in the country. Further, the soil at the site is Class 3m, making it marginal for annual crop production with Subclass m designation associated with low soil moisture, a consequence of rapid drainage of coarse-textured soil. In spring and fall, inundation associated with a high water table can occur. Thus the site is ideal for assessing the effect of manure application on leaching of nutrients.
Phase 1: September 2003 - March 2007
The first years of the La Broquerie Study included research on forage and cattle productivity, nutrient dynamics in soil and groundwater, greenhouse gas emissions, pathogen movement in the system, energy use and efficiency, and economics.
Phase 2: April 2007 - April 2010
Current research at the La Broquerie Study is focused on a more in-depth look at past work examining nutrient and pathogen movement, as well as the introduction of new work including examination of odour. Manure application techniques have been expanded to include both splashplate and Aerway application. (See also Experiment Description)
Phase 3: May 2010 - April 2013
Continued work at the La Broquerie Study will emphasize removal of manure nutrients through intensive forage harvesting.
