Organic horticultural soils lose anywhere from 0.3 to 4 cm of viable topsoil each year that does not regenerate. The main degradation processes involve microbial decomposition, compaction (50%), and erosion (50%). Not much is known, however, about the actual magnitude of the loss due to erosion. The measurement of the spatial redistribution of cesium-137 (Cs-137) provides a rapid and efficient means to quantify this loss. We will measure this radioisotope in 28 fields exposed to different atmospheric agents and subject to a variety of anti-erosion practices in order to quantify the long-term (60+ years) severity of erosion for these soil types.
From 2019 to 2023
This project will help bring about improvements in black peat conservation.

The aim of this project was to leverage the efficiency of drip irrigation and splitting nitrogen inputs into multiple applications to reduce total nitrogen inputs per unit produced and provide better economic and environmental alternatives to conventional irrigation.

Managing potato residues is therefore a big challenge, which will only increase with the enforcement of the Québec Residual Materials Waste Management Policy.

The goal of this project is to boost the number of fresh and processing sweet corn producers in Québec using trichogramma to control European corn borer.
