Inter-row weeding is indispensable for organic farming; however, it is not widely used in Québec for narrow-row crops. With the development of a narrow-row crop weed control strategy, along with early passes of the rotary hoe and tined weeder, farmers would be able to intervene later in the crop cycle and achieve greater control of larger weeds.
The use of a guidance system (e.g., camera or GPS) for very narrow rows could yield greater accuracy at higher speeds. Narrow-row crop weeding will be studied in four experiments conducted on three crops, i.e., green beans, peas, and soybeans. The experiments will take place over three years at the Saint-Bruno-de-Montarville Organic Agriculture Innovation Platform.

This project will develop a versatile tool that will allow to simulate the impacts of agricultural practices on soil organic matter.
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.
