IRDA monitored water extraction by blueberry farms in the Saguenay–Lac-Saint-Jean region between 2015 and 2018. Our measurements indicate that, under current production conditions, lowbush blueberry crops have relatively low water requirements. Furthermore, measured yields were quite variable, even within a single field, and could be forecast with the monitoring tools developed here. The water extraction measurements also suggest that higher yields could be attained in the monitored blueberry fields. Currently, water extraction is generally 50% below the potential evapotranspiration demand. As part of this project, the soil water status at a chosen blueberry farm will be monitored at 40 spots over the course of the production year. We will seek to identify the relationship between water extraction, physicochemical and environmental factors, and yield levels that could help explain yield variability.
From 2019 to 2020

The model’s predictions will be used to calibrate the dose of a thinning agent (ANA) to be applied in two plots, one treated with carbaryl and the other without, over a two-year period.
