Potassium 50% - Sulfur 20% The presence of potassium in this fertilizer gives it the advantage of using it in varieties that need potassium before the fruits are formed and colored, such as grapes and strawberries. It is also an important component in the production and transmission of sugars in the plant. Desert Energy fertilizer is a cheap source of potassium Its presence is essential for photosynthesis. It also helps absorb nitrogen from the soil and increases plant resistance to some diseases. And due to the presence of sulfur, which lowers the PH of the soil and thus works to absorb the nutrients of the plant from the soil, especially the smaller ones. Potassium sulfate is added at the stage of growth and development of the fruits until the harvest stage. It reduces the transpiration processes of the plant, which increases the resistance of these plants to unsuitable weather conditions (heat / drought ....).
