A mix of people, including farmers, students, and researchers, participated in a 4R Nitrogen Management Tour on Wednesday in the Carman area.

The plot tour, which wrapped up at the University of Manitoba's Ian N. Morrison Research Farm, focused on present and future approaches to nitrogen management.

Dr. Mario Tenuta is a professor of soil science at the University of Manitoba.

He talked about some of the work they're doing with spring wheat.

"The big objective of the study is environmental," said Tenuta. "Looking at the loss of nitrogen, particularly greenhouse gases, nitrous oxide, which is more and more of a concern because agricultural soils emit majority of that greenhouse gas. We're finding that managing or controlling what product we used, particularly these enhanced efficiency fertilizer products, reduce the emissions of the N2O."

Wednesday's tour also included a demonstration of some of the new technology that is being used in the field.
