Special Fertilizers

Knlan special compound fertilizers are N-K-Ca-Mg fertilizer formulas designed to supply nitrogen, potassium, calcium, and magnesium for crop nutrition. They are suitable for fruit trees, vegetables, melons, greenhouse crops, and other crops that require balanced nutrient supply.

The formula 14-0-12+4MgO+13CaO means the fertilizer contains 14% nitrogen, 0% phosphorus, 12% potassium oxide, 4% magnesium oxide, and 13% calcium oxide. This helps buyers understand the nutrient ratio before selecting a suitable formula.

The right formula depends on crop type, growth stage, soil condition, and target nutrient needs. Balanced N-K-Ca formulas are suitable for general crop nutrition and calcium supplementation, while high-potassium formulas are more suitable for fruit enlargement and quality-focused stages.

15-0-15+18CaO provides a balanced nitrogen and potassium ratio with higher calcium content. 14-0-30+8CaO contains higher potassium and is more suitable for crops that need stronger potassium supply during fruit development, enlargement, or quality improvement stages.

A formula with magnesium, such as 14-0-12+4MgO+13CaO or 13-0-15+18CaO+2MgO, is suitable when crops require both calcium and magnesium nutrition. Magnesium supports chlorophyll formation and photosynthesis, while calcium supports plant structure and fruit firmness.

Knlan special compound fertilizers can be used for fruit trees, vegetables, melons, greenhouse crops, and other horticultural crops. Common application crops may include tomatoes, peppers, cucumbers, citrus, apples, grapes, melons, and watermelons. The exact formula should be selected according to crop needs and local fertilization practice.
