Calcium Nitrate

Technological Excellence in Norwegian Nutrition

The Norwegian plant «Yara Porsgrun» manufactures potassium nitrate that sets a benchmark for purity in crystalline fertilizers. The formulation contains 46.3% potassium (K2O) and 10–15% nitrogen in nitrate form. This synergy ensures immediate availability of nutrients to the root systems of tomatoes and cucumbers, effectively eliminating the risk of ballast salt accumulation in the rhizosphere.

Chemical Architecture and Performance

• N and K Synergy: The nitrate form of nitrogen facilitates rapid potassium uptake. In drip irrigation systems, this is crucial: the plant avoids wasting energy on compound transformation, directing nutrients straight to the fruit.
• Chlorine-Free Technology: Yara's proprietary manufacturing process ensures total chlorine exclusion, making it the ideal choice for sensitive crops prone to chlorotic stress.
• Solubility Dynamics: The fine crystalline structure guarantees 100% water solubility. When delivered via drip lines, it ensures zero sediment buildup and prevents emitter clogging, thereby extending the service life of irrigation infrastructure.

Field-Proven Harvest Results

Applying this potassium nitrate during the fruit-bearing stages of tomatoes and cucumbers has a direct impact on marketability and shelf life. Potassium serves as a regulator for water balance and carbohydrate synthesis. Consequently, fruits achieve optimal weight, uniform shape, and increased sugar content. Using products from «Yara Porsgrun» minimizes physiological risks associated with potassium deficiency and stabilizes yields even under fluctuating thermal stress conditions.
