WebinarMaking the Most of Secondary Macronutrients
Across all crops, N, P, and K receive a great deal of fanfare for their broad role in promoting crop growth and yield. But in more specialized crops, like potatoes, quality is a factor of equal or greater importance to total yield and secondary macronutrients (S, Ca, and Mg) play a central role in optimizing production. Due to their contributions to specific growth and physiological processes, secondary macronutrients can be more limiting, impacting both yield and quality. Due to the importance of ensuring proper timing of nutrient availability for secondary macronutrients, nutrient source is essential for optimizing yield, quality, and return-on-investment to the grower. Specifically, solubility and nutrient release rate over time. Polyhalite—a naturally occurring mineral—has emerged as an innovative nutrient solution. Providing a gradual release of S, Ca, and Mg, it also contributes a low chloride source of K. This webinar will dig into the importance of secondary macronutrients in potato production and review North American trials of polyhalite as a component of a complete potato fertility program. This webinar will be moderated by Spudman managing editor Crystal Nay and is sponsored by ICL.
All attendees will be eligible for 1 CEU.
