Quantifying Structural Stability of Agricultural Soils in Ontario

Soil compaction and surface crusting degrade soil structure, reducing aeration and root penetration, and ultimately impacting crop performance. With the trend towards larger farms, more massive equipment and increasing unpredictability of climate, the …

Long Term Field Trials To Examine Yield, Soil Productivity, And Environmental Impacts Of Ontario Corn, Soybean And Wheat Production Systems

Using the long-term rotation experiment near Elora, ON (established 1980) to study the impacts of tillage and diversity of crop rotations on a number of agri-environmental factors.

ACTIVE

Ecosystem Services From Streamside Buffers

Studying the impact of trees on carbon sequestration and greenhouse gas emissions in terrestrial and aquatic ecosystems.

ACTIVE

Biomass Crops And Soil Carbon Storage

Monitoring soil and water quality after land-use change to biomass crops.

ACTIVE

Long-Term Impacts Of Cover Crops

State-of-the-art experiment at Ridgetown comparing several different cover crop monocultures and mixtures to no cover crop in mixed vegetable-grain crop rotations.

ACTIVE

Transfer Of Agricultural Phosphate From Edge-Of-Field To Surface Waters Via The Riparian Zone

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.

ACTIVE

Tillage And Cropping Effects On The Nature Of Soil Organic Matter

Not all soil organic matter is the same, and soil management practices may impact types of organic matter differently. This research looks to explore how tillage and crop rotations impact stable and unstable forms of organic matter.

ACTIVE

Using UAV Sensors To Assess Soil Organic Carbon Levels

Tradition methods for estimation soil organic carbon are expensive, time-consuming, and labour-intensive. This research looks to use drones and different optical sensors to remotely estimate soil organic carbon quickly and reliably.

ACTIVE

Reducing Phosphorus Losses With Cover Crops

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.

ACTIVE

Integrated Soil Sensing And Digital Mapping For Precision Agriculture Services In Ontario

Developing sensors, theories, and algorithms to be used to characterize and map soils for precision agriculture.

ACTIVE

Updating Carbon Models For Modern Agricultural Practices

Re-tuning carbon models with modern cropping cultivars, practices, and soil amendments.

ACTIVE

Nitrification Inhibitor Use On Manure

Nitrogen losses from manure come at an economic cost to farmers in the form of lost nutrients, and an environmental cost in the form of nitrate leaching into surface waters. This research is determining if nitrification inhibitors may improve manure ni …

ACTIVE

Developing A Soil Sulfur Test For Ontario

Due to changes in deposition rates of sulfur from the atmosphere, there is an increasing need for sulfur with certain crops in Ontario. But in order to recommend sulfur fertilization rates, accurate and reliable measured soil measurements need to be de …

ACTIVE

Sulfur Response In Corn, Soybean, And Winter Wheat

Not all crops have the same demand for sulfur fertilization. This research is exploring response to sulfur fertilization in corn, soybean, and winter wheat crops in Ontario.

ACTIVE

Greenhouse Gases From Manure Storage

It is important that we understand environmental impacts of different manure storage practices. This research explores greenhouse gas emissions from different storage systems and manure handling.

ACTIVE

Environmental and economic value of soil services

Healthy soils provide essential ecosystem services (e.g. nutrient recycling, carbon sequestration, climate regulation, and water filtration) that sustain plants, animals, and humans. The growing trend towards simplifying systems in Ontario and the nort …

ACTIVE

Developing rapid methods for soil health assessment in Ontario

Exploring novel ways to track the carbon chemistry of healthy soils.

ACTIVE

Crop Rotations, Microbial Communities, And Greenhouse Gas Emissions.

Measuring the impact of simple versus complex rotations on microbial communities and N2O emissions from these production systems.
