Composition and properties

Nitrophoska is a complex mineral fertilizer that contains primary macronutrients—nitrogen (n), phosphorus (p), and potassium (k), as well as additional elements such as calcium, magnesium, sulfur, and micronutrients (iron, manganese, zinc, copper, boron, and molybdenum). This balanced composition provides comprehensive nutrition for plants, improving their growth, development, and resistance to stress factors.

Main nutrients (NPK)

• Nitrogen (N): a key element for synthesizing proteins, nucleic acids, and chlorophyll. Nitrogen promotes active leaf growth, increases photosynthetic activity, and overall plant metabolism. Nitrogen deficiency manifests as yellowing of leaves (chlorosis) and slow growth.
• Phosphorus (P): important for energy metabolism, root system formation, flowering, and fruiting. Phosphorus participates in photosynthesis, respiration, and energy transformation processes. Phosphorus deficiency leads to slow growth, delayed ripening, and reduced yield.
• Potassium (K): regulates water balance, promotes protein and carbohydrate synthesis, strengthens cell walls, and increases plant resistance to diseases and unfavorable climatic conditions. Potassium improves fruit quality by enhancing their taste and storability. Potassium deficiency manifests as weak plants, browning of leaf edges, and reduced yield.

Additional elements

• Calcium (Ca): necessary for forming strong cell walls, improving plant structure, and increasing resistance to mechanical damage and diseases. Calcium also plays a role in enzyme activation and signal transmission within cells.
• Magnesium (Mg): the central atom of chlorophyll, involved in photosynthesis. Magnesium is necessary for enzyme activation and carbohydrate synthesis. Magnesium deficiency causes chlorosis in the intercellular spaces of old leaves.
• Sulfur (S): involved in the synthesis of amino acids and proteins, essential for plant growth and development. Sulfur also affects the aromatic and taste qualities of fruits and vegetables.
• Micronutrients: iron, manganese, zinc, copper, boron, and molybdenum play important roles in various enzymatic processes and overall plant health. They are involved in chlorophyll synthesis, enzyme activation, stabilization of structural proteins, and nutrient transport.

Physical and chemical properties

Application methods (soil application, spraying, etc.)

1. Soil application: the most common method, involving the even distribution of nitrophoska over the soil surface followed by tilling. This ensures uniform nutrient supply to the plant roots and improves nutrient availability. It is recommended to apply fertilizer before sowing or planting, as well as to repeat feeding during the active growth period.
2. Fertigation (foliage): soluble nitrophoska is added to irrigation water, allowing plants to quickly absorb nutrients. This method is particularly effective in drip and micro-irrigation systems, ensuring targeted plant nutrition and minimizing fertilizer losses.
3. Foliar feeding: used for rapid correction of nutrient deficiencies by spraying dissolved nitrophoska onto plant leaves. This method ensures quick absorption of nutrients through the leaves, especially under stressful conditions or rapid growth.
4. Precise application: granulated nitrophoska can be applied directly near the plant's root system, reducing fertilizer losses and improving efficiency. This method is suitable for automated fertilizer application systems and minimizing environmental impact.

Timing of application (seasonal recommendations) the optimal timing of nitrophoska application depends on the type of crops and climatic conditions. Seasonal recommendations include:

• Spring: apply nitrophoska before the active growth period begins to ensure necessary nutrition at the start of the growing season.
• Summer: for some crops, additional fertilization may be applied to maintain growth and yield.
• Autumn: apply nitrophoska to prepare plants for winter, strengthen the root system, and provide nutrition for the next season.
• Winter: in regions with mild climates, fertilizer application may be possible during the winter period; however, in harsh regions, it is recommended to limit fertilization to spring and autumn. It is important to consider weather conditions and avoid applying fertilizer during heavy rains or droughts to prevent nutrient leaching and ensure maximum effectiveness.
