Is there a yield and quality advantage to using biological nitrogen fixation products?
This is a question the Saskatchewan Wheat Development Commission (Sask Wheat) is aiming to answer in a trial at Scott, Saskatchewan.
Carmen Prang, agronomy research specialist with Sask Wheat, says there are different fertility treatments the trial is targeting: a low, medium, and high fertility treatment, the foliar applied products, and untreated checks for a total of 36 plots.
“We know that wheat requires large amounts of nitrogen. We’re getting most of that from our soil through residual levels and mineralization. But then we’re also adding it through our fertilizer,” Prang explains.
“There’s also been targets set with [reducing] emissions that we’re trying to reduce those as well. All of these factors have put a lot of pressure on farmers to be able to make the most of their nitrogen fertilizer.”
