The importance of potassium management in potato production

Potatoes use more potassium than any other nutrient, including nitrogen. Potassium is required for nutrient movement in the potato plant. It is essential for the makeup of over 40 different enzymes and is involved in more than 60 different enzyme systems in plants. Potassium is crucial in quality potato formation. Plants lacking in potassium often display various signs of deficiencies, the most common being discoloration of older leaves on the plant as compared to younger leaves on the plant. Depending on soil type, 90 to 98 percent of total soil potassium is unavailable. Typically only 1 to 2 percent of conventional potassium fertilizer applied to the soil is available at one time. As an essential major nutrient for crop production, potassium needs to be available to the plant at all stages of growth. Growers can provide the potassium their potato crop needs, when it needs it, by using efficient potassium nutrient products.
