Calcium nitrate tetrahydrate is primarily used in agriculture as a rapid-release nitrogen and calcium compound fertilizer, for improving acidic soils, rapidly supplementing nitrogen and calcium for crops, preparing nutrient solutions for soil-free cultivation, and enhancing fruit quality. ‌‌

Usage

Quick-acting fertilizer:

Provides nitrate nitrogen (about 11.8%) and water-soluble calcium (about 23.7% CaO) that can be directly absorbed by plants, with fast fertilizer efficiency and no need for soil transformation.

Acid soil improvement: 

Calcium ions neutralize soil acidity. Long-term application can improve soil structure, prevent compaction, and is suitable for acidic plots lacking calcium.

Physiological disease control: 

Rapidly replenish calcium sources to prevent physiological disorders such as navel rot, fruit cracking, and leaf margin scorch caused by calcium deficiency, and enhance crop stress resistance.

Soilless cultivation substrate: 

Due to its complete water solubility and stable ionic form, it is often used as the core calcium and nitrogen source for hydroponic/aeroponic nutrient solutions.

Quality and early maturity regulation: 

Promoting the increase of fruit hardness, improvement of color, and acceleration of the ripening process, especially beneficial for melons, fruits, vegetables, and tuber crops.
