Farming Podcast | Cotton Fertility Timing Trial | XtremeAg

In this episode of Cutting the Curve, host Damian Mason is joined by Matt Miles and agronomist Stephanie Zelinko to break down the results of a cotton fertility challenge conducted in partnership with AgroLiquid. The trial, hosted on Matt's farm, tested three fertility programs designed by Matt, Kevin Matthews, and Kelly Garrett, each limited to a $50 foliar application budget with the goal of achieving 1,750 lbs (3.5 bales) per acre. Despite different application timings and nutrient mixes, all three programs yielded strong results, with Matt’s at 1,806 lbs, Kelly’s at 1,800 lbs, and Kevin’s at 1,724 lbs. The key differentiator was nutrient timing, especially consistent potassium and calcium delivery throughout the crop’s reproductive phase. The discussion emphasizes cotton’s high nutrient demands, the role of spoon-fed foliar treatments, and opportunities to trim costs without sacrificing yield by strategically managing application timing and product selection.
