Great Salt Lakes Minerals, a division of Compass Minerals, launches a powerful 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 at: 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."

In his 2006 publication, "Best Management Practices for Fertilizer", Mikkelsen points to a study done by Oregon State University in which potatoes removed approximately 515 lb./A of potassium from the soil, and approximately 34 lb./A of sulfur, in addition to other nutrients such as nitrogen, phosphorus, calcium and magnesium.

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.
