By: Extension nutrient management specialists Dan Kaiser & Fabian Fernandez Recent wet growing seasons have put a greater emphasis on nitrogen management. Summary data form MVTL labs sent by Brian Williams shows that nearly two-thirds of the basal stalk N tests were in the low category in 2018 and 2019. The closest years before that were 2014 and 2016, with nearly 50% of the samples in the low category, but the remaining years dating back to 2011 had only 25-33% of samples in the low category. If we factor in the marginal categories for 2018 and 2019, roughly three-fourths of fields tested likely had some N deficiencies while only 10% of fields came back with excessive N levels, which clearly illustrates that N loss was a significant issue the past two growing seasons. Residual nitrate levels in the soil post-harvest Jeff Vetsch, a soil scientist at the Southern Research and Outreach Center (SROC) in Waseca, documented 2019 residual soil test levels lower than he has seen i
