Misconceptions of Chemical Use on Crops

Technology and research advancements have changed how farmers use chemicals on their crops. Even with these improvements, there’s a lot of misinformation out there amongst consumers about how chemicals are used on crops.

On the Dec. 14 episode of Seed Speaks, we’re taking a closer look at what the ag industry do to stop these rumours dead in their tracks. We’re joined by Ian Affleck, vice-president of plant biotechnology at CropLife Canada, and Stuart Smyth, an associate professor in the Department of Agricultural and Resource Economics at the University of Saskatchewan (U of S).

Affleck works with domestic and international agricultural stakeholders and governments on the development of policies, regulations, and science related to plant biotechnology. Prior to CropLife Canada, he worked at the Canadian Food Inspection Agency for 10 years, focusing on the regulation of novel plants and new varieties. Affleck has a bachelor of science in agriculture from the Nova Scotia Agricultural College, and a master’s degree in agriculture from the University of Guelph.

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.
