Potato Europe – The Potato Event of 2015

This year, the Potato Europe trade fair visited Belgium. From September 2 to 3, 2015, 191 exhibitors from 12 countries invited visitors to the trade fair site in Tournai, Wallonia. During the two days on which the trade fair was held, over 9,000 visitors learned about the latest trends and developments in potato cultivation. Alongside numerous exhibitors of related agricultural technology, fertilizers and plant protection products, K+S KALI GmbH was also represented with its own stand at these year’s Potato Europe.


K+S KALI GmbH offered extensive information on the use of fertilizers for potatoes. There were presentations of fertilizers containing potassium and magnesium and the special impact they have on potato cultivation. This is because the potato is a complex crop, for which fertilizer use is largely dependent on the type of production (ware, starch, seed or industry potatoes). In general, the balanced supply of nutrients ensure potato quality as well as yields. Potassium not only determines starch content, but, along with further nutrients, such as magnesium and boron, also positively influences the content of further elements that impact tuber quality. It should be noted at the same time that not every potassium fertilizer is suitable for potato production. The disadvantage of the use of chloridic potassium fertilizers is that they adversely affect tuber starch conversion and storage. With Patentkali, potassium is made available in sulfur-based form, which is optimal for the use of potassium fertilizers in a way that ensures quality. In addition, Patentkali contains the nutrients magnesium and sulfur, which have a decisive influence with respect to high yields and top quality.

A magnet drawing visitors to the K+S KALI GmbH stand was a model of the Liebig barrel, which illustrates the “Law of the Minimum,” as well as the potato plants with leaf and tuber symptoms of nutrient deficiencies positioned around it. Many visitors took advantage of the opportunity to take photographs of the Liebig barrel and the plants or had photographs taken of themselves next to them.


Alongside personal recollections of visiting the fair, the specialist dimension also featured prominently in intensive discussion of nutrient deficiency symptoms. The careful examination of the plants and the identifying an insufficient supply of potassium, magnesium, boron or other trace nutrients was assisted by K+S KALI employees who provided advice and information about products.


The KALI chips – made from potatoes for which Patentkali was used as a fertilizer – as well as the brochure “Deficiency Symptoms ABC” proved very popular this year too. The content of the brochure is also available at no charge in various languages as an app from the Apple App Store and the Google Play Store.
