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.

It’s been eighteen months. Eighteen months since students stepped foot here on the Guelph campus, eighteen months since I had a London Fog in the
Nitrogen fertilizer use in agriculture has been increasing; unfortunately, the same is true for nitrogen losses to the environment. Weather, as well as the frequency and timing of nitrogen applications, can affect how efficiently nitrogen is used by the crop to produce yield and how much is lost. One way to improve nitrogen fertilizer use in corn is to split the application so that some is applied at planting and the rest is applied in the growing crop. Farmers can then adjust the rate and timing of the second application depending on the weather.
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.
You can’t stay on the mountaintop forever. After an incredible start to 2021 with the Midwest Cover Crops Council Conference in February, we’ve been taking
Plants can’t access all of the water that’s stored in the soil. Some water is held tightly in very small pores, some water freely drains through large pores, and some is held loosely by the soil so that it isn’t lost but plants can still use it.
Using fertilizer efficiently is vital for managing agroecosystems sustainably. It makes the most of crop productivity while protecting the environment. As agriculture has intensified, the use of synthetic nitrogen (N) fertilizers has increased.
The warming of the earth’s climate and an increasing global population is presenting enormous challenges for the agricultural industry to increase food production. More frequent extreme weather events caused by climate change, such as drought, are problematic for the Northern Corn Belt, where simple two-crop rotations of corn and soybean are common.
Wow! What a busy start to 2021! With the Midwest Cover Crop Council Conference wrapping up in late February and gearing up for planting season,
"It’s not a simple thing to look at a 2,000-acre grain operation and say, 'let’s incorporate cover crops.'"
New article feat #ontag farmer @farmerstrang and #UofG @RidgetownCampus prof Richard Vyn on the complexity of adopting #covercrops

I wish there was more of this!Majority of erosion occurs in the fall and spring. Worked soybean ground has 0% cover. Some risk with early frost but I expect good success in SW ON. Minimal expense. Even if we get 4” top like wheat. Blend with fert = no extra time when busy. https://twitter.com/JoshBoersen/status/1463859994441433092
Less is very often more with #cover crops. 30 lbs Oats broadcast with light incorporation after manure.
We planted these mid september and they are already as thick as we'd like to have going into winter.
