Cross-Canada agronomic and environmental benefit of advanced 4R nitrogen management of grain corn

Background

Project is headed by Dr. Mario Tenuta, Dept. of Soil Science at the University of Manitoba with Researchers from Manitoba and the rest of eastern Canada.

Objectives:
  • Objective 1: Determine if advanced 4R N management for QC, ON, and MB conditions change the most economical rate of nitrogen (MERN) and improves grower return on investment (ROI). This will build on and complement the research we have already funded in Manitoba aimed at updating nitrogen recommendations for modern hybrids.
  • Objective 2: Determine if advanced 4R N management for QC, ON, and MB conditions reduces N losses to the environment.
  • Objective 3: Determine if a novel practice of single vs double injection bands in combination with depth placement and N source reduce N losses and increase corn grain yield in ON.
  • Objective 4: Advance grower tools for in-season nitrogen rate determination.
