Accounting for soil and weather conditions: Methods and tools to help fine-tune your N

Abstract

On this episode of Advancing Nitrogen Smart (https://blog-crop-news.extension.umn.edu/search/label/Nitrogen%20Smart) we discuss methods and tools to account for soil and weather conditions as you execute your nitrogen management strategy. Which tissue and nitrate testing options are the most beneficial, and when should you test? How does understanding the nitrogen cycle help you interpret these results? How do drought and /or saturated conditions affect available nitrogen? What can be reasonably achieved with rescue treatments? Why is it important to end your season with the right amount of residual nitrogen in the field? Brad and Dan discuss this - and much more - on today's show.
