The project evaluated and compared the effectiveness of two types of subsoil plows (mounted on a bulldozer or a tractor) operated parallel and perpendicular to the tile drains to improve soil drainage conditions and productivity compared to control plots. Three sites for the trials were selected in the Montérégie, Centre du Québec, and Chaudière-Appalaches regions on highly compacted clay soils with poor natural drainage. The productivity gains in commercial corn, soybean, and grain crops were compiled, analyzed, and compared in the light of the changes observed in the physical properties and hydraulic behavior of the soils.
