Predicting nitrogen rates: Factors and resources for Minnesota farmers

UMN Extension Nutrient Management Podcast

After spending last episode talking about the background and history of nitrogen rate recommendations in Minnesota, today on episode 14 we’re talking about what to keep in mind as you begin predicting your nitrogen rate needs. How do yield, and nitrogen use efficiency (NUE) factor into decision making? Are there any N rate databases available to Minnesota growers? What are the pros and cons of a variable rate strategy, or cover crops for example? Brad and Dan talk about that and much more on today's episode.
