Deep soil compaction adversely impacts crop productivity and its effects endure over a long period of time. It is important to educate farmers on the causes of deep compaction. The Terranimo® tool, a European Web-based platform, simulates the effects of farm equipment traffic on soil compaction by calculating the depth propagation of soil surface loads.
This tool was developed in Europe and validated with a series of test benches that assessed most tires available on the market inflated to various pressures and with applied loads that simulated most types of farming equipment (tractors, trailers, self-propelled machinery). The software, which will be adapted to Québec conditions, will include specific equipment and will optimize tractor balancing. It will also incorporate typical soil and water content profiles that can be selected from an on-line soil map. An apparatus consisting of Bolling-type pressure sensors connected to a computer or programmable logic controller will also be created to measure deep compaction (during demonstration days) in order to provide farmers with tangible results and enhance their knowledge of soil compaction. Lastly, educational material, which will be presented during training days, will be developed to facilitate use of the software, including a document on the causes and effects of deep soil compaction.

This tool will be a valuable asset in the effort to maintain and improve soil health.

Ten test sites will operate over a two-year period on farms spread over ten Québec regions to compare the performance of winter and spring cereals.
The aim of this project was to consolidate current scientific knowledge with a view to developing a spatially referenced tool to predict diffuse sediment, nitrogen, and phosphorus exports at the farm and watershed scale.

The goal of the project is to improve biological methods for controlling the cabbage seedpod weevil in canola crops. In this project, initiated by Agriculture and Agri-Food Canada and conducted in Québec by UQAM, IRDA is performing an economic analysis of the practices under study.
