Quantifying the Compactability of Agricultural Soils In Ontario

Lead Applicant: Richard Heck

Research Priority: Soil Health

Program Type: Tier 1

Funding Cycle: 2026/2027

Research Centre: Ontario Crops Research Centre - Elora

Research Summary: Although the fundamentals of soil strength and resilience have been widely studied, there is limited information on how the compactability of agricultural soils varies across Ontario. This project will use advanced soil imaging and soil organic matter analysis to better understand how land management history affects soil strength and compactability. The project will include controlled stress testing of topsoil cores and soil aggregates, as well as the development of technology for in-field measurement of topsoil stress and strain. Long-term research plots will be used to evaluate the effects of different land management practices over time. Selected agricultural soil transects will also be studied to capture a range of soil types and landscape positions. Findings will help improve management practices for mechanized field crop production, specialty crops, and intensive livestock grazing systems.
