Fall is approaching, harvest is in full swing in many areas and has already finished in others. Aside from a few rainy days, and some thunderstorms over the past month, we haven't seen much for precipitation or soil recharge.
The 2021 growing season was filled with many agronomic challenges, the most notable being that it was one of the hottest and driest on record in Saskatchewan and yield was significantly impacted in many areas. Grain prices have risen, but with that, so have input prices. When looking ahead to the 2022 crop year, the 2021 drought will continue to have impacts on management decisions.
In this episode of Wheat Profit, we are going to focus on soil fertility and considerations after a drought. We know that yields fell sharply below targeted yield, which means there should be higher residual nutrients. Higher nutrient residuals can reduce next year’s fertilizer bill, but there are some considerations to be made around nutrient availability and variability. Severe moisture deficits can also create significant yield variability throughout a field. Drought effects nutrient cycling, nutrient availability, and can even skew soil test results. But how will all this impact management decisions for next year?
The guest for this episode is Lyle Cowell. Lyle is the Manager of Agronomy services with Nutrien in North East Saskatchewan. Lyle covers fertility considerations after a drought, residual nutrients and what you can expect, nutrient variability throughout the field and what the main causes are, soil testing, and considerations for fall fertilizer applications.
