How does nitrogen release (mineralize) or become tied up (immobilize) in residue depending on soil moisture, temperature, and microbial activity? Are biological soil tests (like the Haney test and Solvita CO₂ burst) precise tools for calculating exact fertilizer rates, or should they be considered general risk indexes? What role do strong soil structure and expansive root systems play in maximizing nitrogen uptake? Brad Carlson, Anna Cates and Dan Kaiser discuss this and much more on the 41st episode of the Advancing Nitrogen Smart podcast.\nGuests:\nBrad Carlson, Extension educator (Mankato)\nDan Kaiser, Extension nutrient management specialist (St. Paul)\nAnna Cates, state soil health specialist (St. Paul)\nAdditional resources:\nSoil health and water quality: How are they connected?\nThe connection between soil organic matter and soil water\nThe state of Minnesota's soil health: How many farmers are doing no-till, cover crops, and more\nNitrogen Smart\nMinnesota Office for Soil Health - MOSH\n---\nFor the latest nutrient management information, subscribe to the Nutrient Management Podcast.
