Benefits of the compound:
Potassium nitrate: Soad is suitable for all irrigation systems and can be used as a spray on the leaves. It contains nitrogen in an easily absorbed form. This element is important for the formation of protoplasm, which makes up all living cells. It is also involved in the synthesis of amino acids, proteins, and chlorophyll.
It contains potassium in a high concentration in an easily absorbed form, which is the form of potassium nitrate. The element potassium has a large and important role in plants, as it
 It helps in the activity of more than 10 enzymes, helps in photosynthesis, and regulates the process of opening and closing stomata. It is responsible for transporting nutrients to and from the cell, so it increases the sugar content in the fruits (Cantilever grapes).
It works to increase the germ content of the cell, so it works to increase the size of fruits (tomatoes, cucumbers, zucchini).
 Potassium nitrate: It is preferable to use it on tuber crops such as (potatoes, yams, and onions), as it helps increase the plants’ ability to store, thus significantly increasing the size of the tubers and the yield.
 Potassium nitrate: important for the formation of flowers and knots, so it is preferable to fertilize it during the flowering and licking stage
Usage rates: - Ground use: from 3-7 liters/acre depending on the crop and age of the plant. – Foliar use: from 22 cm/liter of water during the vegetative growth stage and before flowering
