With multi-mode-of-action control, your healthy, high-yielding soybean crop is finally free to flourish. representation of GHG emissions and carbon sequestration in agriculture, Dr. Roland Kröbel, ecosystem modeller at Agriculture and Agri-Food Canada (AAFC), emphasizes that two key activities need to be advanced. The first is scaling research efforts that support our understanding of practices and their impacts on GHG sources and sinks. For example, identify the nitrous oxide emissions from adopting a split nitrogen application approach. The second is ensuring the scope and approaches to data collection (e.g., surveys) evolve to effectively capture the adoption rate of innovative on-farm practices and technologies contributing to climate change mitigation. Dr. Nathan Pelletier, associate professor at the University of British Columbia, shares that “producing estimates is a pretty dataintensive exercise, but the information required is stuff that most farmers already have a really good handle on.” The key factors Pelletier’s research team relies on to estimate the carbon intensity of crop production, which primarily uses an activitybased calculation approach, include “the kinds and amounts of fertilizers and crop protection products that are used, seeding rates and yields, and machinery use (types and numbers of passes for things like tillage, fertilizing, spraying, harvesting, etc.). We combine this information with soil and climate data based on the farm’s location, models for estimating emissions from soil continued on page 20
