Digital resources to support soil carbon storage and improved nitrogen management. Weston Family Foundation Soil Health Initiative

The project is developing digital soil mapping tools to allow farmers to estimate the soil’s ability to supply nitrogen to inform “Right Rate” nitrogen fertilizer application. The project is national in scope and use regionally accepted measures of soil nitrogen mineralization to train prediction models and provide site-specific prescription maps to inform more precise nitrogen management at the field scale.

In Canada, routine soil testing to estimate growing season nitrogen mineralization is not available in all regions, despite sound science supporting these measures on a regional basis. Research has demonstrated that while there is not a single test that works across regions, within regions, there are reliable tests to measure soil nitrogen mineralization.
