Audience(s): Cow-Calf   Project Type(s): Demonstration

Increasing land values means producers need to produce more off the same or smaller land base. Knowledge on perennial and annual forage mixtures including their yield, animal performance and cost to establish, paired with soil health, nutrient cycling and methane emission levels is novel and needed. Soil-water-plant-animal interactions are complex and often not examined together resulting in a fragmented understanding of grazing ecosystems. Given the differences that exist between perennial and annual forages and between grass and legume species, the project objectives will be to evaluate forage yield (biomass), grazing animal performance, stand persistence, soil and water parameters, enteric methane emissions, C sequestration, nutrient (N, C) dynamics and cycling and system costs of four different mixtures (2 perennial and 2 annual). This project will use a collaborative, multi- disciplinary approach to measure, monitor and compare these interactions in perennial and annual forage binary mixtures.


Goal #3: Enhance ecosystem services and biodiversity on lands managed by beef producers

Goal #9:Increase the financial viability of beef production in Canada

Goal #2: Reduce the greenhouse gas footprint of Canadian beef per unit of product produced

Indicators Addressed:
  • Grasslands, tame pastures and native ecosystems are maintained or enhanced.
  • Practices that support carbon sequestration and minimize emissions are understood and/or employed.
  • Continuous learning regarding beef production is pursued.
Communication Tools:

Project summary and results will be available on, as well as profiled through the Livestock and Forage Centre of Excellence. Opportunities exist to present the results of this project at workshops, field days, conferences, popular press articles, scientific journal articles, videos and social media.
