Adjusting the sprayer to spray a certain amount of toxic solution per hectare with a predetermined diameter of the drain and a certain number of drains per square centimeter is called calibration. Calibration is the determination of the amount of toxic solution that is spread by the sprayer in a specific surface unit (e.g., ha). Due to the variety of sprayers, the calibration of sprayers is certainly different.



Iron is one of the most important and essential micronutrients for all plants. Iron deficiency is one of the most common nutrient deficiencies in orchards and agriculture of most agricultural areas of the country. An important point to note is that all micronutrients except molybdenum are inaccessible to plants by increasing the pH of the culture medium, but become absorbable to plants by decreasing the pH of the culture medium. The ideal pH range for plants varies depending on their ability to absorb nutrients.
