Management Practices: Nitrogen management

Nitrogen inhibitors in cropping systems

Farmers and researchers are teaming up through the Living Lab–Ontario Nitrogen Management project to find smarter ways to grow crops while reducing environmental impacts. On a sixth-generation family farm, innovative trials are testing nitrogen inhibitors, measuring greenhouse gas emissions, and exploring practices like composting and biochar to improve soil health and nutrient efficiency. By combining farmer experience with scientific research, the project is uncovering practical, data-driven solutions that boost productivity, build more resilient soils, and help reduce agriculture’s climate footprint.

Reducing GHG in Dairy Farming

Through the Living Lab–Ontario Greenhouse Gas Emissions on Dairy Farms project, farmers and scientists are working together to measure and reduce the climate impact of dairy production. Using advanced monitoring at a commercial “supersite” farm, researchers track greenhouse gas emissions from the crops that feed dairy herds and test practices like enhanced-efficiency fertilizers. The goal: practical, data-driven solutions that help dairy farmers improve nutrient management, reduce emissions, and build a more sustainable future for milk production.

Soil Health Day

Peterborough area farmers focus on soil health amid dry conditions. With extremely dry conditions putting pressure on Peterborough area farmers this season, producers are digging into soil health, and what it could mean for their crops. Story by Marc Woodhouse has more.

Exploring Nitrogen BMPs to Cut Greenhouse Gas Emissions in Corn Production

Can the way you manage nitrogen make a difference for the environment?
This study under Ontario’s Living Lab – Ontario (LL-ON) program is using Holos, Agriculture and Agri-Food Canada’s whole-farm modelling tool, to find out. Researchers are measuring the impact of nitrogen beneficial management practices (N-BMPs) on greenhouse gas (GHG) emissions across 11 study sites in Ontario.

This work is providing valuable insights into how different nitrogen management strategies can help farmers lower emissions, improve efficiency, and contribute to climate-friendly agriculture.
