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.

Tuesday, June 28: Potato Sustainability
John Mesko, Potato Sustainability Alliance
Formed in 2020, the Potato Sustainability Alliance (PSA) joins all facets of the potato industry — from growers to processors to crop protection specialists — to further the industry’s quest to be sustainable. PSA head John Mesko will share updates on how that’s being done and field some questions from the audience.
Wednesday, June 29: Weight Loss in Storage
Ragen Darrington, IVI
A large portion of potatoes spend more time in storage than they do in the ground. Weight loss during that period can be caused by a variety of reasons, but the end result is still the same: product and economic loss. Ragen Darrington of Industrial Ventilation will present on how to manage and minimize potato weight loss while in storage.
Thursday, June 30: Roundtable Discussion
Some of the top potato-focused university researchers in the U.S. join us to discuss some topics of their choice, as well as field some questions from the audience. Our guests will include Amanda Gevens of the University of Wisconsin, Andy Robinson of North Dakota State University and Mike Thornton of the University of Idaho.

The demand for increasing potato yield keeps going up in all classifications of potatoes from seed to fresh, processing and chippers. Often in our zeal to increase yield, quality parameters such as specific gravity, internal disorders, skin set and others often unnecessarily take a back seat and often do decline. Proper crop nutrition, taking into consideration the critical demand timings of the essential nutrients and proper application mechanics, can help to ensure the high yielding high quality potatoes that growers are looking for and the high quality that processors and consumers are demanding. This webinar will offer physiologically based suggestions on the best crop nutrition applications for the best potato crop. This webinar will be moderated by Spudman managing editor Zeke Jennings and is sponsored by YARA North America. Jimmy Ridgway and Dr. Rob Mikkelsen to speak.
Webinar participants will be eligible for 1 CCA CEU in Nutrient Management.

An introduction to soil health in potato cropping systems from the USDA-SCRI Potato Soil Health Project
Live on February 16, 2021 @ 2 p.m. ET
The USDA-Specialty Crop Research Initiative Potato Soil Health Project was formed in 2018 to help the potato industry explore what soil health means in potato cropping systems. Four objectives were defined with the first two consisting of research projects exploring management practices and the resulting effects on soil measurements, indicators, microbiome communities and soil-borne pathogens. The third objective aims to explore the economics of potato production and how improved soil health effects the grower’s bottom line. The final objective is to communicate to the potato industry what soil health means and extend research-based results from the objectives to the larger agricultural community.
The Potato Soil Health Project is presenting a webinar to introduce three distinct aspects of the program including:
1) potato production and soil health
2) disease suppression in potato production systems
3) complexities of potato production economics.
