Soil organic carbon transformation under different forms of PPMS
Soil organic carbon (SOC) serves as a vital indicator of soil fertility, crucial for sustainable agricultural practices. The project aims to examine the effects of applying pulp and paper mill sludge (PPMS) on soil organic carbon (SOC) dynamics within agricultural land.
Novel use of pulp and paper mill residuals
The pulp and paper sector is a significant industry in Canada, especially in rural communities, with noticeable improvements in efficiency and environmental impact over the past decades. However, challenges persist in managing waste residual streams, often ending up in landfills. The project aims to tackle these challenges by exploring management approaches and alternative uses for pulp and paper mill sludge (PPMS). Learn more.
Impact of organic amendment on soil health under a changing climate.
Disposal of organic wastes to landfills poses environmental challenges, including greenhouse gas emissions and soil contamination. The project addressed these issues by assessing the impact of three different organic amendments on soil health, carbon sequestration, and greenhouse gas mitigation in Quebec and Ontario. The research provided insights into sustainable soil management practices, aiding agricultural producers in adapting to climate change while contributing to a circular bioeconomy.

Mapping spatiotemporal variability of apparent electrical conductivity in managed and natural landscapes in Western Newfoundland
Amid increasing demands on natural resources and climate change
impacts, traditional soil mapping methods prove inefficient.
This project addressed this challenge by using digital
technology to map soil properties in western Newfoundland. The
findings helped identified effective soil moisture management
practices and predictive models that can enhance agricultural
productivity and water quality.
