NPK 15:15:15 + 10 S is an easily soluble and quickly digestible compound mineral fertilizer that contains the main macroelements: nitrogen, phosphorus and potassium.
The balanced ratio of macroelements in the product contributes to the significant nutrient uptake while ensuring a stable yield and improved production quality.
Nitrogen is the building block of proteins, amino acids and chlorophyll. They are necessary for photosynthesis, energy production, dry matter accumulation and plant fruiting. In the presence of phosphorus, nitrogen is more readily taken up by plants. In the initial phases of their development, plants absorb phosphorus more intensively and later distribute and use it to synthesize organic substances.
In the process of crop development, it is important to provide crops with the amount of phosphorus needed for the growth and development of the root system and for better nutrient uptake.
Potassium contained in the plants stimulates the formation of healthy stems and increases stress resistance by ensuring an optimal water regime for the plants. Better potassium stocking in plants also helps to improve their nitrogen supply and nitrogen transformation into amino acids and proteins. Potassium positively influences the anatomical growth of plant organs and tissues, which gives them greater strength and resistance to lodging, diseases and pests.
Sulfur content is an advantage of NPK 15:15:15 + 10 S compound fertilizer. Sulfur plays an important role in oxidation-reduction processes, energy balance of the plant organism, functioning of phytohormones, activation of enzymes, chlorophyll synthesis, etc. It is necessary for nitrogen uptake and amino acid and protein production. What makes NPK 15:15:15 + 10 S fertilizer so highly productive is the fact it collects in a single granule all the necessary nutrients the plant needs in the initial stages of its development.
Each granule ensures a balanced uptake of essential nutrients and helps to fully satisfy the plant needs. The application of this fertilizer guarantees maximal effectiveness of the funds input and provides supply of nutrients of full value.
- Significant increase of nutrient take-up ratio;
- Possibility for accurate and controlled input of comparatively low norms of certain elements, which is difficult to achieve in separate fertilization;
- Reduction of the losses from wash-out and lift-off of nutrients;
- Lower expenditures in single input into the soil – transportation, time and labor.
