Nitrates & placement: Factors for reducing nitrogen loss to water

Photo credit: Anna Cates, Minnesota Office for Soil Health

We’re talking all about nitrate management and placement as important factors for reducing nitrogen loss to water on today's episode of the Advancing Nitrogen Smart Podcast series. Different forms of nitrogen have their own potential for loss. How does nitrogen already in the nitrate form differ from ammonium for example? How does basic soil science slow down or speed up nitrogen transformation? Why can't nitrates be easily stabilized in the fall in Minnesota? How do other factors like pH affect nitrogen transformation? This and much more in today's discussion.
