NPK 20-20-20

“NPK 12-12-36” contains nitrogen, phosphorus and high percentage of potassium, which has been produced to provide the required elements of the plant during the period of reproductive growth and crop maturity. Consumption of this fertilizer improves the color, aroma, taste, as well as increases the quantity of the crops. Potassium is necessary for the production of enzymes, vitamins and protein in plants. It is effective in transporting nutrients inside a plant. Also, potassium increases yield, better taste, color and marketability, increasing crop resistance to environmental stresses and diseases

Ironate" contains iron and potassium and also humic acid, fulvic acid, and organic matter. Iron is an essential element in plant growth and plays an important role in photosynthesis and chlorophyll production. In the case of iron deficiency, the photosynthesis process in the plant is disrupted and chlorosis appears in the leaves. Supplying iron through the soil is one of the main methods of supplying this element, which, in combination with organic matter, increases absorption, efficiency and finally increases the yield of crops. The movement of iron in plants is influenced by potassium. According to the time of potassium consumption, which is at the same time as the transfer of materials made in the leaves to the reproductive points of the plant. Therefore, potassium plays an important role in the final stage, which is the stage of increasing yield. Due to the alkalinity of the soil in most regions of the country, the absorption and duration of iron in the soil are very short, and even the plant cannot absorb it sufficiently. Therefore, the use of humic acid along with iron fertilizer is the best recommendation for treating iron deficiency in plants and providing. This is because by acidifying and balancing the pH of the soil, iron fertilizer can be absorbed with the greatest amount.
