Calcium and magnesium fertilizers mainly include calcium magnesium nitrate, calcium ammonium nitrate and other nitro composite products, of which calcium magnesium nitrate contains 16% calcium oxide and 6% water-soluble magnesium, and calcium ammonium nitrate is made by modifying agricultural ammonium nitrate process. The products generally use chelation technology to improve the activity of calcium and magnesium, and the pH value is mostly maintained at about 6.5 to ensure compatibility with pesticides and other fertilizers. The breakthrough in the core process is reflected in the stable compatibility of nitrate nitrogen and medium elements, which increases the nitrogen utilization efficiency by more than 30% compared with traditional fertilizers.
