Modern complex granular nitrogen-phosphorus-potassium-sulfur fertilizer 15-15-15+8s effectively contributes to increasing productivity and product quality as well as soil fertility restoration. It can be used as a basic fertilizer in areas with a percolative regime of soil in order to sufficiently provide plants with all macronutrients throughout the growing season. It is especially effective for crops with a high need for mineral nutrition conditions (sugar beet, sunflower, corn, rapeseed, etc.) during intensive cultivation technologies. Due to the use of fertilizer in rows during sowing, plants have a better starting growth, and a well-developed root system also formes. The yield increases and the quality indicators of cultivated crops improve namely - oil content, sugar content, gluten, protein and starch content.

Due to the optimal ratio of basic trace elements in the fertilizer intensive initial plant growth and the formation of an optimal leaf apparatus are ensured. At the same time, plants better absorb water and nutrients from the soil as well as form an aboveground mass faster. The main part of phosphorus is absorbed by plants at the beginning of the growing season, creating its reserve. It then moves easily from old tissues to young ones. Due to potassium, photosynthetic activity increases, the activity of enzymatic systems activates, the water retention capacity of plants increases, the absorption of soil moisture, the resistance of plants to extreme conditions – high and low temperatures, changes in soil moisture and immunity to diseases and pests improves. The fertilizer is especially effective for crops that are sensitive to a lack of sulfur (legumes, cabbage, sugar beets, etc.).

• Nitrogen-phosphorus-potassium fertilizer NPK+S 15-15-15+8S belongs to complex mixed fertilizers that are produced in a "wet" way by mixing nitrogen-, phosphorus-, potassium- and sulfur-containing products;
• it does not lose its physical properties during storage;
• statistical solidity of pellets is not less than 5 MPa;
• mass fraction of pellets 2-5 mm is more than 90 %;
• 100% friability;
• it is highly dissolvable in the soil solution;
• it quickly compensates for the shortage of nitrogen, phosphorus, potassium and sulfur;
• the aftereffect of phosphorus and potassium is well manifested on the subsequent crops.

• 300-700 kg/ha of fertilizer is applied during the main fertilization while autumn ploughing, depending on the crop type and soil fertility.
• 200-400 kg/ha is applied before autumn ploughing levelling, depending on the crop type and soil fertility.
• 200-400 kg/ha of fertilizer is applied for pre-sowing cultivation, depending on the crop type and soil fertility.
• 100-150 kg/ha of fertilizers are applied with a top dressing of row crops (beets, sunflowers, corn).
• 50-100 kg/ha of fertilizer is applied in row application during sowing.
• 100-150 kg/ha of fertilizer is applied during row top dressing of row crops (beets, sunflowers, corn).
