Water Stable Soil Aggregates and Associated Carbon 70 years Post-Agriculture
Rachel Bloom, 4th year HBSc Water Science (supervisor Dr. Amanda Diochon)
Soil aggregates contribute to soil structure and can protect soil organic carbon from decomposition by the microorganisms. Agricultural activities generally disrupt soil aggregates, contributing to the loss of soil organic carbon. This study explores if and how soil structure has changed 70 years after agricultural abandonment using a local, long-term experiment in which former agricultural land was planted with red pine or white spruce, or left empty. This research will contribute to understanding how reforestation and tree species influence soil structure and the distribution of carbon in surface soils following agricultural abandonment.
