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.

This project will provide a better understanding of interactions between a vegetable polyculture system and hedges composed of shrubs and perennials in order to enhance the impact of beneficial insects on vegetable crops.
This project aims to explore and experiment new approaches and ways to preserve, develop, and enhance the MRC’s bio-food sector, and reduce or eliminate the water deficit on the island.
