Calcium Nitrate: A Powerful Tool for Modern Farmers
Calcium nitrate, a synthetic compound rich in calcium and nitrogen, is gaining attention among farmers for its dual role in plant health and disease prevention. This versatile fertilizer supports plant growth and bolsters their natural defenses, making it a valuable tool in modern agriculture.
Calcium nitrate can be applied in two ways: as a side dress or a foliar spray. For side dressing, apply 3.5 pounds per 100 feet (1.59 kg per 30.48 m) to provide essential nutrients directly to the roots. Alternatively, as a foliar spray, it can treat specific diseases like blossom end rot, cork spot, and bitter pit in apples. When applied early in fruit development, calcium nitrate stabilizes cells and prevents these issues by promoting healthy growth.
Produced by reacting nitric acid with limestone and then adding ammonia, calcium nitrate is a water-soluble fertilizer that offers both calcium and nitrogen. However, it's not an option for organic gardeners due to its synthetic derivation. Before application, it's crucial to conduct a soil test to ensure the right balance of nutrients. For a foliar spray, mix 1 cup of calcium nitrate in 25 gallons of water (128 grams in 94.64 liters). Crops like tomatoes, apples, and peppers can particularly benefit from calcium nitrate applications. It aids in cell formation and neutralizes acids to detoxify plants, making it a powerful tool for enhancing crop yield and quality.
Calcium nitrate, with its ability to provide essential nutrients and bolster plant defenses, is a valuable addition to modern farming practices. While not suitable for organic gardening, it offers significant benefits when used appropriately, as guided by soil tests and crop-specific needs.
