<p>Cation exchange capacity and cation balancing are the topics of the day in this episode of the Nutrient Management Podcast. What are the definitions of cation exchange capacity and cation balancing? How is CEC measured, and are those estimates reliable? What does the research say about CEC and CB and their role in a nutrient management strategy? What should farmers remember about cation exchange capacity and cation balancing for their own operations?</p><p><strong>Guests:</strong></p><ul><li>Fabian Fernandez, Extension nutrient management specialist (St. Paul)</li><li>Daniel Kaiser, Extension nutrient management specialist (St. Paul)</li><li>Carl Rosen, Extension nutrient management specialist (St. Paul)</li></ul><p><strong>Additional Resources:</strong></p><ul><li><a href="https://mnsoilfertility.com/research/timing-of-k-application-for-corn-and-soybean-production/">Timing of K application for corn and soybean production</a></li><li><a href="https://blog-crop-news.extension.umn.edu/2023/05/chloride-and-soybean-what-to-know-about.html">Chloride and soybean: What to know about potash fertilizer management</a></li><li><a href="https://extension.umn.edu/crop-specific-needs/fertilizing-corn-minnesota#impact-of-cation-exchange-on-corn-k-guidelines-2239913">Impact of cation exchange on corn K guidelines</a></li><li><a href="https://blog-crop-news.extension.umn.edu/2022/11/four-soil-test-myths-that-farmers.html">Four soil test myths that farmers should know</a></li><li><a href="https://blog-crop-news.extension.umn.edu/2023/05/corn-planting-and-nitrogen-management-5.html">Corn planting and nitrogen management: 5 things to consider</a></li><li><a href="https://blog-crop-news.extension.umn.edu/2022/10/fall-k-fertilizer-decisions-how-should.html">Fall K fertilizer decisions: How should corn growers prioritize applying potassium?</a></li><li><a href="https://blog-crop-news.extension.umn.edu/2022/04/potassium-management-maps-showing-soil.html">Potassium management: Maps showing soil clay type could help Minnesota farmers</a></li></ul><p>---</p><p><a href="https://blog-crop-news.extension.umn.edu/search/label/NM%20podcast">Click here</a> to listen to all Nutrient Management Podcast episodes.</p><p>For the latest nutrient management information, <a href="https://nutrientmanagement.transistor.fm/subscribe">subscribe to the Nutrient Management Podcast</a>.

<p>Today on the Advancing Nitrogen Smart Podcast we discuss nitrogen fertilizer management and surface water issues. When did we first become aware of nitrates appearing in surface water? What are some of the effects, and who is being affected? What are Minnesota's current nitrate-reduction strategy benchmarks - and are we on target to meet them? What are some of the challenges and success stories Minnesotans should know about? Which organizations can I contact if I'd like to become more involved? </p><p><strong>Guests:</strong></p><ul><li>Brad Carlson, Extension educator and water quality specialist (Mankato)</li><li>Dan Kaiser, Extension nutrient management specialist (St. Paul)</li></ul><p><strong>Additional resources:</strong></p><ul><li><a href="https://www.pca.state.mn.us/air-water-land-climate/reducing-nutrients-in-waters">MPCA Nutrient Reduction Strategy</a></li><li><a href="https://www.mda.state.mn.us/pesticide-fertilizer/nitrogen-fertilizer-bmps-agricultural-lands">Nitrogen Best Management Practices (BMPs)</a></li><li><a href="https://www.dnr.state.mn.us/whaf/key-concepts/ws_def.html">HUC-8 Watersheds</a></li><li><a href="https://bwsr.state.mn.us/soil-water-conservation-districts">Soil and Water Conservation Districts (SWCDs) in Minnesota</a></li></ul><p>---</p><p><br></p><p>For the latest nutrient management information, <a href="https://nutrientmanagement.transistor.fm/subscribe">subscribe to the Nutrient Management Podcast</a>.

<p>It's the end of March, which means it's time for the annual Spring Fertilizer Outlook. What are field conditions like throughout Minnesota? What early fertilizer application options might MN growers want to consider? Which early fertilizer application practices might MN growers want to avoid, and why? What are growers excited - or hesitant - about? What about N carryover credits in this more typical season?
