Summary
Brad Carlson and Dan Kaiser discuss sidedressing in today's Advancing Nitrogen Smart Podcast episode. What's the big-picture rationale behind sidedressing? How can sidedressing or split-applying be beneficial in terms of avoiding nitrogen loss? Since nitrogen uptake isn't linear, what growth stages coincide with peak daily demand on the crop? Are there any significant risks in starting a sidedress application early in the season? What have past experiments shown regarding positive and / or negative responses to sidedressing? How should inhibitors be used with sidedress / topdress? What should farmers know about soil types and tile drainage when making sidedress decisions? This and much more on the 37th episode of the Advancing Nitrogen Smart podcast series.
