Like nitrogen and phosphorus, potassium is major nutrition`s element contributing to large, steady and high quality crops. Crops need potassium and nitrogen in fairly comparable amounts however everyday agriculture stands proof to a lack of balance in the intake of these nutrients to the detriment of the potassium. The potassium used in fertilizers, especially in developing countries, is much below the amount of the potassium in the crops. By way of consequence the amount of the potassium in the soil diminishes and so does soil fertility.
