Year-Round E-15 Could Help Farmers, But Not As Much As Less Restricted Trade

Jan 30, 2026

By Clayton Baumgarth

During a stop in Des Moines, Iowa, on Tuesday, President Trump reiterated his support for E-15 fuel, and said House and Senate leadership are “very close” to securing year-round access to the biofuel.

E-15 is a fuel made up of 15 percent ethanol, a product of corn. It typically isn’t sold all year due to the Clean Air Act, which restricts “higher volatility fuels” during summer to reduce smog formation.

Farzad Taheripour, a professor of agricultural economics at Purdue, said allowing the sale of E-15 throughout the year would benefit farmers.

“It is important to generate a secure market for this product, to help farmers to be able to continue to invest in the industry,” he said.

Taheripour estimated about 30 percent of all corn grown in the United States is used to create ethanol and its byproducts.

Video: Winter Canola Trial in Mississippi | Can It Work for Double Cropping? | Pioneer Agronomy

Can winter canola open new opportunities for growers in the Mid-South? In this agronomy update from Noxubee County, Mississippi, Pioneer agronomist Gus Eifling shares an early look at a first-year winter canola trial and what farmers are learning from the field.

Planted in late October on 30-inch rows, the crop is now entering the bloom stage and progressing quickly. In this video, we walk through current field conditions, fertility management, and how timing could make this crop a valuable option for double-cropping soybeans or cotton.

If harvest timing lines up with early May, growers may be able to transition directly into another crop during ideal planting windows. Ongoing field trials will help determine whether canola could become a viable rotational option for the region.

Watch for:

How winter canola is performing in its first season in this Mississippi field

Why growers chose 30-inch rows for this trial

What the crop looks like as it moves from bolting into bloom

Fertility strategy, including nitrogen and sulfur applications

How canola harvest timing could enable double-cropping with soybeans or cotton

Upcoming trials comparing soybeans after canola vs. traditional planting

As more growers look for ways to maximize acres and diversify rotations, experiments like this help determine what new crops might fit into existing systems.
