This two-year project was conducted on an organic polyculture farm in southern Québec (Ferme des Quatre-Temps).
The first stage of the project focused on describing the polyculture system and how the hedges are planted and maintained. Interactions between the polyculture and the hedges were studied, based on the insects associated with crops in the cabbage family. Insects were sampled on plots to check for parasitism of immature pest stages (caterpillers and pupa) on the crops and in adjacent hedges to determine what natural enemies and pollinators use them as a refuge. This data was used to identify the plant species most used by natural enemies and pollinators. The project also looked at the economic aspects of planting recommended species and the economic benefits of various control strategies for Lepidopteran pests of the cabbage family.
From 2017 to 2018
Pest, weed, and disease control, Ecosystem protection
Farmers who implement the actions recommended in this project will be contributing to the preservation and enhancement of agricultural biodiversity.

In this study, we will test alfalfa meal pellets in a broccoli crop planted on plastic-covered irrigated mounds and we will compare them with two organic fertilizer, in addition to a control treatment in which no nitrogen is added.
The project consisted of manufacturing and testing a portable rain simulator to estimate, under various conditions, what proportion of irrigation water a crop is able to use.

Meeting nitrogen requirements mainly through the use of a highly stable form of fertilizer can minimize nitrogen losses, provide nitrogen amounts closer to the plant’s actual needs.
