Great Salt Lakes Minerals, a division of Compass Minerals, launched a mobile tool designed to help potato growers and crop consultants make more accurate soil nutrient decisions and maximize yield potential.

The Potato Potassium Uptake Calculator is now available here or is available for download to an iPad device via the Apple App Store for iPad. Those who wish to download the application to an iPad can visit the Apple App Store. Please note that the app is not optimized for the iPhone, because the required data input is not for the small screen.  

According to Dr. Robert Mikkelsen with the International Plant Nutrition Institute (IPNI), “potatoes managed for maximum productivity have a high demand on soil nutrients.”

Numerous university studies have documented the benefits of proper potassium fertilization in potato production. Potassium availability influences the tuber size and yield, in addition to a number of tuber quality factors such as specific gravity, blackspot bruise susceptibility, chip and fry color and storage quality. Potassium deficiencies decrease photosynthesis, reducing dry matter and starch formation.1

"We wanted to provide potato growers and field consultants with an effective tool to help them understand how much potassium was being removed from their soil, based upon their yield,” explains Dave Furbeck, marketing communications manager with Great Salt Lakes Minerals. “We plan to develop additional on-line tools to help potato producers make smart soil nutrient choices and get the most yield potential possible out of their fertilizer budget.”

The next question is how much K is taken up each day, during the crop cycle. Dr. Dale Rush's work on K uptake, several years ago, showed that once the soluble K is depleted, it takes 7 to 10 days to replenish it! It is critical, therefore, that adequate soluble K is available during the "grand growth" stage!
