The water-soluble chlorine-free complex fertilizer NPKS is used both for pre-sowing application into the soil and for pre-sowing treatment of seeds and foliar feeding of plants by spraying them in greenhouses and on open ground.

The water-soluble chlorine-free complex fertilizer NPKS contains basic nutrients such as nitrogen, phosphorus, potassium and sulfur.

In terms of physical and chemical properties, the water-soluble complex chlorine-free NPKS fertilizer must meet the requirements and standards specified in the table:






Powder or fine crystals from white to grayish

Mass fraction of ammonium nitrogen (),%, not less


Mass fraction of phosphates in terms of P2O5,%, not less


Mass fraction of К2О,%, not less


Mass fraction of sulfate ions (),%, not less
or in terms of sulfur,% not less



Mass fraction of moisture,%, no more


If fertilizer comes into contact with the skin, rinse the area with running water.
Influence of elements on plants and meaning
        Nitrogen is a substance that plays an important role in plant metabolism, and is also a part of organic nitrogen compounds, proteins, enzymes, nucleic acids, chlorophylls, alkaloids, many types of vitamins and other substances.
        Lack of nitrogen. Main symptoms: impaired growth of vegetative organs as a result of impaired formation of chlorophyll and the formation of light green or yellowish-green leaves.
        Abundance of nitrogen. Excessive nitrogen supply leads to an increase in vegetative mass, a decrease in yield and a deterioration in quality. Reducing the sugar content in sugar beets leads to an increase in "harmful" nitrogen in the sugar production process, a decrease in the starch content in potatoes, and the accumulation of nitrates in vegetables and melons that are harmful to humans and animals.
          Phosphorus plays an important role in energy metabolism and various other metabolic processes in plants. It is involved in carbohydrate and nitrogen metabolism, photosynthesis, respiration, and the breakdown of organic substances into enzymes.
          Lack of phosphorus. Plants suffer from a lack of phosphorus at a young age, when their root system is not sufficiently developed and has a feature of small development. Even with the subsequent feeding process with a large amount of phosphorus, the negative consequences of a deficit during this period lead to an irreversible situation.
           Phosphoric nutrition is also important in the formation of reproductive organs. A lack of phosphorus during this period stops growth and slows down the crop, which leads to a decrease in yield and a deterioration in the quality of the crop.     
          With a phosphorus deficiency, plant growth quickly slows down, and their leaves (first at the edges, then over the entire surface) become gray-green or reddish-purple. In cereals, the accumulation and formation of grain stalks is reduced.
           Potassium is involved in the management of the main processes of plant development and plays an important role in their life. These include: increases the activity of enzymes, participates in photosynthesis, regulates metabolism in plant tissues, participates in carbohydrate and protein metabolism, regulates the water balance in plants, increases plant resistance to stress, including cold, drought, pesticides and diseases.
           Effects on plants. Potassium in plants performs various physiological functions. It has a positive effect on the state of cytoplasmic colloids, increases their hydration, increases puffiness and stickiness, which improves the metabolism in cells, and also increases the resistance of plants to drought.
         Sufficient potassium intake increases plant resistance to diseases such as powdery rose in cereals and rust diseases, as well as to fungal pathogens in vegetables and potatoes.
        Potassium increases plant resistance, stem strength, and the quantity and quality of flax and hemp fiber.
        Sulfur plays an important role in plant life. The main part of it is contained in plant proteins: amino acids and organic compounds-enzymes, vitamins, and fats. Sulfur is involved in the metabolism of nitrogen and carbohydrates in plants, respiration, and fat synthesis.
        From the point of view of physiological importance to plants, sulfur may take the third place after nitrogen and phosphorus. According to a number of Russian and foreign scientists, the most frequent sulfur deficiency in grain products is perceived by producers as a nitrogen deficiency.
        Sulfur has a positive effect on product quality-it increases the percentage of gluten in wheat, increases the amount of fat in sunflower and soybeans.
       In excess of sulfur, the leaves turn yellow at the edges and get tangled inside, and then turn a darker color and do not develop.

Safety requirements: The premises intended for the production and packaging of NPKS fertilizers must be provided with supply and exhaust ventilation. Work with NPKS fertilizer must be carried out in compliance with personal protective measures. When preparing solutions, it is recommended that the consumer wear rubber gloves. Mixing with other substances is strictly prohibited!

Do not smoke, eat or drink while working with complex fertilizer.

 If it enters the stomach, drink a few glasses of a slightly pink solution of potassium permanganate, induce vomiting. After work, wash your face and hands with soap and rinse your mouth.

Packaging: NPKS fertilizer weighing - 100 g, 150 g, 250 g, 300 g, 500 g, (1, 3, 5, 10) kg is packed in plastic bags and in paper, plastic bags. Also in shipping containers, in corrugated boxes for chemical products. Temperature of NPKS complex fertilizer - before packing should be no more than plus 30 ° С.

Transportation: NPKS fertilizer is transported by all means of transport, ensuring its safety and in accordance with the rules for the carriage of goods in force for this type of transport.

Storage: It is recommended to store NPKS fertilizer in covered, dry and clean rooms - protected from moisture ingress, away from heating devices, inaccessible to children and animals, separately from food and medicine. Storage temperature from 0 ° C to +30 ° C and relative air humidity not more than 75%. Storage and transportation of NPKS fertilizer is carried out separately from other materials and substances.

Guarantee term of storage: 24 months from the date of production.


       Plants in the period of rapid growth and the formation of concentrated vegetative organs (horns and leaves) absorbs and assimilates large amounts of nitrogen.        

        Effect on plants. The nitrogen supply determines the growth process, the volume and intensity of protein synthesis and other nitrogenous organic compounds in the plant. Nitrogen deficiency especially affects the growth of vegetative organs. The photosynthetic apparatus is a weak development of the leaf and horn as a result of nitrogen deficiency, which in turn restricts the formation of productive organs and leads to a decrease in yield and a decrease in the amount of protein in the product.



         Effects on plants. Among the organic compounds of phosphorus, there are complex, multi-molecular, nitrogenous bases consisting of carbohydrates (ribose and deoxyribose) and phosphoric acid - nucleic acids play an important role in plant life. Phosphorus is a part of phosphatides (phosphoglycerides), which form protein-lipid cells and control the absorption of various substances. Most of the phosphorus in the plant is in the form of phytin, as well as vitamins and various enzymes.

          Potassium deficiency leads to disruption of some metabolic processes, which leads to reduced productivity and poor quality. Potassium increases the cold resistance of plants by increasing the osmotic pressure in the cells and increasing the sugar content in them.


        Lack of sulfur. The growth and development of plants is disrupted, and small pale yellow leaves are formed on long branches. Experiments on wheat show that the lack of sulfur during the growing season leads to a decrease in photosynthesis, yield and grain quality.
