Biocomp 7-18-20+17 SO3 Organomineral Fertilizer
Biocomp 7-18-20+17 SO3 Organomineral Fertilizer has been formulated with Unaldi Fertilizer’s half-century of deep field experience, specifically for agricultural production areas where root development and fruit quality are targeted. Our company, whose foundations were laid in 1975 and which introduced domestic chelated fertilizer technologies to the sector in 1982, has combined mineral nutrition with rich organic matter derived from leonardite in this product. Its potassium sulfate-based structure and chlorine-free formula make Biocomp 7-18-20 one of the most reliable base fertilizers for chlorine-sensitive fruit and vegetable groups.
Roles of Macro Elements in Plant Physiology
The macro elements within Biocomp 7-18-20 undertake these critical roles in the plant’s seasonal cycle:
- Phosphorus (P₂O₅ – 18%): It is fundamental for energy transfer and root development. It triggers lateral root formation during the planting stage and increases yield potential by enhancing flower setting.
- Potassium (K₂O – 20%): It is the quality expert. It improves the sugar content, color, and aroma of the fruit. By making the cell wall durable, it maximizes the plant’s resistance to frost, drought, and diseases.
- Nitrogen (N – 7%): It supports vegetative development, ensuring the continuity of photosynthesis by keeping the green parts of the plant healthy.
- Sulfur (SO₃ – 17%): It plays a key role in soil reclamation. By regulating the pH balance in high-pH soils, it facilitates the uptake of locked phosphorus and trace elements by the plant.
Complementary Power of Micro Elements and Humus
The 80% mineral content is supported by essential micro elements (Fe, Mn, Zn) for plant metabolism. Iron (Fe) prevents leaf yellowing by protecting chlorophyll synthesis, while Zinc (Zn) affects shoot length and stem durability. The 12% organic matter and 8% humic-fulvic acid derived from leonardite increase the water-holding capacity of the soil and optimize fertilization costs by ensuring that minerals are retained in the soil.
