Iron-Deficient Soybeans Cost Minnesota Farmers When Margins Are Already Tight

By Tadeo Ruiz Sandoval

Corey Hanson, who grows soybeans in Gary in the Red River Valley, has waged many battles against Iron Deficiency Chlorosis, also known as IDC, in his crops.

“It's always there someplace,” said Hanson. “Just depends on how severe it is, depending on what the spring did, how the [snow] melt happened, and how much rain we've received throughout the spring.”

The condition appears when the soybean plants aren’t able to access the iron they need to grow. Affected soybeans’ leaves turn yellow early in their life cycle. When that happens, the plants aren’t actively photosynthesizing, which stunts their development.

Hanson has been trying multiple different treatments over the last 20 years. Lately, he’s been applying liquid iron to his fields, which he says has helped mitigate the severity of IDC. But that increases his costs.

Those cost increases come at a time when many farmers’ operating expenses are already high. Soybean prices are also lower than they were a few years ago. Hanson said that paying for liquid iron to improve yield, in hopes of higher profit, feels like a gamble.

"We don't know right now what the full price of our soybeans will be next year. We can have an idea, a hope, but we don't know," said Hanson. "All my cards to play to get a better yield in hopes of a profit could be all for naught, but I don't know that now."

Understanding Nitrogen Loss Through Denitrification

Video: Understanding Nitrogen Loss Through Denitrification

Denitrification is one of the three main pathways for nitrogen loss, but what is it really, and how much nitrogen do we stand to lose?

In this episode, Lyle Cowell is joined by Dr. Erin Daly from the University of Guelph to break down denitrification and the conditions that drive nitrogen loss in the soil. They explore how nitrogen can be lost as nitrous oxide and nitrogen gas, what conditions drive losses and when they are most likely to occur.

Erin also shares how CanN2ONet, a national research network, is helping us better understand nitrous oxide emissions across Canada. From field towers that measure emissions to research into regionally tailored best management practices, discover how the network is working to help growers improve nitrogen use efficiency and help reduce nitrogen losses across the country.
