Agriculture Roundup for Friday February 17, 2023

The Western Grains Research Foundation has created a series of twelve regional factsheets that show the benefits of diversifying crop rotations.

The Resilient Rotations project is part of the Integrated Crop Agronomy Cluster (ICAC) that is evaluating various crop rotations to help create more productive, sustainable, and resilient cropping systems on the prairies.

The project is led by Dr. Kui Liu, a research scientist with Agriculture and Agri-Food Canada (AAFC).

“We are approaching crop rotation by looking at a systems approach – all the elements that impact crop rotation from soil health, economics and yield to local growing conditions,” Liu said. “It’s a more holistic way to look at crop rotation and one we hope will provide new insights and options for farmers in Western Canada in a more customized, prescriptive type of approach.”

Supplemental Nitrogen on Soybeans: Can Early Nitrogen Increase Yield?

Video: Supplemental Nitrogen on Soybeans: Can Early Nitrogen Increase Yield?

Can supplemental nitrogen help soybeans reach higher yield potential? Technical Agronomist Tim Sickman walks through an ongoing trial at the Nutrien Innovation Farm in Owensboro, Kentucky, exploring whether a modest amount of nitrogen applied at planting can support higher-yielding soybean environments.

The trial compares 30 pounds of supplemental nitrogen across both 15- and 30-inch rows, along with treatments that include sulfur and micronutrients. Similar trials conducted in 2024 and 2025 delivered a six- to seven-bushel yield response, prompting the team to expand the research this season.

Early observations show that treated soybeans are slightly taller and averaging about two additional nodes on the main stem. These added nodes could create more opportunities for blooms and pods, but the true results will come at harvest when the team evaluates pod development, seed fill and final yield.
