In-season nitrogen: Tools for deciding on source, timing, placement, and inhibitors

In this episode of the Nutrient Management Podcast, we’re discussing nitrogen decision tools. How much are we actually at risk of losing fall or spring applied nitrogen because soils are saturated in May? What options do we have to assess nitrogen loss following heavy rain? If a grower is planning on applying nitrogen in season, what suggestions would you have for sources, timing, placement, and inhibitors? How late in the growing season can you apply nitrogen and what should you consider?
