Calcium nitrate — mineral fertilizer containing nitrogen and potassium. It is used to feed tomatoes and cucumbers both in open and greenhouse soil. The preparation has the form of crystals and is characterized by high potassium (K2O – 46.3%) and nitrogen (N – 13.8%) content. This allows effectively supplying plants with necessary nutrients at various stages of their development. Calcium nitrate contributes to improved yield and product quality by maintaining the balance of mineral substances in the soil. The use of calcium nitrate is especially relevant under intensive cultivation of tomatoes and cucumbers, where rapid restoration of nutrients after harvest or low soil fertility is required. The preparation easily dissolves in water, ensuring uniform distribution of components throughout the root system of plants.
