We're examining the effect of recent heavy rainfall on input decision-making in today's Nutrient Management Podcast. What adverse or severe weather conditions did parts of Minnesota recently experience? How does it compare to past events? It's currently mid-July; what did the Minnesota Drought Monitor say about our drought levels before the rainfall? Was the soil profile able to accept more water as a result? What effect did the heavy rain have on nutrients in the field? At this point in the season, are corn crops past the risk of damage? What effect do soil types have on both the amount of N recommended, and the speed at which the N can potentially leave the field? All this and more on today's episode.

Guests:

• Brad Carlson, Extension educator (Mankato)
• Daniel Kaiser, Extension nutrient management specialist (St. Paul)
• Jeff Vetsch, U of M researcher (Waseca)

Additional Resources:

• Field Notes talks about what to expect after heavy June rains (recorded 2025)
