Potassium has positive effects on the root development and growth of plants. It is also indisputable that phosphorus is efficient on the root formation and development likewise; through the Fas-K which is applied from the dripping and as a result of the chelation of potassium thanks to the special structure of phosphorus, it will be possible that the plants receive these two elements in a short time in all negative conditions of the soil; in this way, root efficiency will be ensured.After the application of Fas-K, stagnation in offshoot ends and peaks will end. When Fas-K is applied from the soil; fruit growth and fruit elongation will be guaranteed, amount of dry substances will considerably increase. When it is applied from the soil and the leaf in shape deformities of fruits; such shape deformities in newly growing fruits will disappear. Thanks to the togetherness of potassium; when it is applied from the soil and the leaf in all kinds of climate and soil conditions, it reaches to all points of the plant. Through such a fast and smooth intake of potassium, natural defense systems of plants will be activated and plants will become much more robust and durable against virus-based diseases. While the potassium has a suppressing and resolving effect on the fungous and bacterial diseases with its composition; it will also be effective on clearing the blocked transmission bundles. On products having internal discharges in their stems and fruits due to such diseases, potassium takes its place in the tissues very quickly and ensures these parts to be filled. Intensive and healthy blooming is ensured in upper applications through Fas-K
