In addition to nitrogen, phosphorus, magnesium and micronutrient elements required by plants, this fertilizer composition contains a high amount of potassium element (36%) which is another main element required for the growth and fruiting of plants. Also, in order to increase the absorption of elements and the plant's tolerance against environmental stresses, a balanced amount of amino acids has been added to this fertilizer composition, which has turned it into a favorable combination to meet all the nutritional needs of plants.

In general, potassium is responsible for the transfer of carbohydrates from leaves to storage organs such as seeds, fruits, and tubers, which provides the conditions for obtaining a product with good quality, uniformity, and good color, and as a result, it increases the yield and quality of the product. The use of potassium-containing fertilizer compounds during flowering increases the durability of flowers and greatly increases the quantity of flowering.

It is recommended to use German PNP fertilizer formula 121236+1 at the end of the vegetative period and the beginning of the reproductive period after flowering until the time of harvest, in the form of foliar spraying or irrigation.
