Livestock Species and Diet Influence Manure

Canada - The Canada Research Chair in Applied Soil Ecology with the University of Manitoba says diet is one of the factors that will influence the nutrient levels contained in composted livestock manure, writes Bruce Cochrane, University of Manitoba
"Composting recipes and stages" were among the topics covered last week as part of a Field Clinic in Soil and Manure Management at the University of Manitoba's National Centre for Livestock and the Environment.
Dr Mario Tenuta, Canada Research Chair in Applied Soil Ecology with the University of Manitoba, says nutrient levels will vary from species to species and diet wil also play a role so recipes will change.
In terms of diet in a particular livestock species it can be a factor.
Particularly in terms of swine manure, depending on the stage of the animals, the manure can have different liquid contents but then also have different salt contents because the different feeding stages may have different salt contents.
Dr Tenuta says by composting animal manure, producers have the opportunity to produce a new product that has its own niche in cropping systems.
He acknowledges the raw material has its uses and advantages but composting has its advantages, for example reducing the volume of the material so it takes less time and is less costly to apply.
