Calcium Salt[Calcium Nitrate Tetrahydrate]

A. The spraying concentration of calcium salt[Calcium Nitrate Tetrahydrate] is generally 0.25% ~ 0.5%, especially when growth regulators such as naphthalene acetic acid are added, which will help crops absorb and utilize calcium.

B. When calcium salt[Calcium Nitrate Tetrahydrate] is used as a top dressing because the nutrients of calcium salt fertilizer are easily lost, it should be used in small amounts and multiple times to avoid unnecessary waste of fertilizer.

C. When calcium salt[Calcium Nitrate Tetrahydrate] fertilizer is used as a base fertilizer, it can be used in conjunction with decomposed organic fertilizer, potassium fertilizer, and phosphate fertilizer (such as superphosphate). However, it cannot be mixed with fresh or untreated manure and compost because these fertilizers will generate organic acids during the fermentation process, causing the calcium nitrate fertilizer to decompose into nitric acid, which will not only hurt crop growth but also cause calcium nitrate and other fertilizer nutrients to be lost. The loss outweighs the gain.

Nitric acid will not only hurt crop growth but also cause calcium nitrate and other fertilizer nutrients to be lost. The loss outweighs the gain.
