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 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.

This project involved an exhaustive survey of viruses, phytoplasma, fungi, and nematodes in nurseries and strawberry fields to determine the exact causes of strawberry decline disease in Québec.
