Opinion: GHG debate needs debit-credit balance

May 17, 2023

The home plate in baseball is 17 inches wide.

I listened to a presentation by the University of Saskatchewan agricultural economist Richard Gray at the end of March. In his submission, he suggested there was an error in greenhouse gas emission accounting. Kevin Hursh mentioned this in his column on page 11 of the April 6 issue.

Gray hypothesized that the accounting does not account for the carbon dioxide withdrawn from the atmosphere, converted to energy, stored in a kernel of grain, and exported to a user. The farm does not get credit for that exported carbon.

Industry champions support his hypothesis. I hear words like “rewarded,” and that past practices should be in the reward mix and the United Nations’ Intergovernmental Panel on Climate Change coefficients are wrong.

But the IPCC protocols for reporting emissions do address this energy transport. The accounting for respiratory emissions is on a worldwide scale. Their protocol is slightly less than a one-to-one debit and credit.

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.
