Potassium fertilisation influences both the yield and quality of potatoes. The crop is characterised by a very high potassium requirement and undersupply can lead to significant yield losses. However, quality features such as starch content, deep-frying colour and storage stability are also influenced by potassium. Physiological problems associated with potassium deficiency such as internal black spots and after-cooking blackening may also be remedied by ensuring an adequate supply of potassium.
Listen our experts’ recommendations on optimising potassium supply, and learn about the negative consequences of a shortage of this essential nutrient.
