The corn-soybean rotation is the dominant cropping system on farmland throughout central Canada and the midwestern United States. However, long-term research shows that this rotation has lower crop yields, soil quality, resilience to climate change, and profitability.
Phosphorus is an essential nutrient for plant growth – including the algae that grow in rivers and lakes. When phosphorus is lost from agricultural soils into waterways, it can allow algae to grow rapidly, which causes problems for fish and humans.
Understanding the microbial world in the soil is key to finding sustainable agricultural practices that work to protect the environment. Using a unique approach that combines the disciplines of soil…
Assessing legacy P that exists in riparian buffer strips and the impact of freeze-thaw and flooding/drought on the cycling and release of this P to surface waters.
Using field and controlled-environment studies to investigate the relationships between cover crop species, soil test P levels, and P runoff losses from soils under freeze-thaw conditions.
