NPK compound fertilizer features
Granulated in one batch for a compact, uniform structure that delivers stable, long-lasting nutrition with minimal soil impact.
High nutrient content
Delivers a high concentration of essential main nutrients to effectively support robust crop growth.
Fewer by-components & uniform structure
Ammonium phosphate, for example, contains no unnecessary by-components: its anions and cations are the main nutrients absorbed by crops, giving a relatively uniform nutrient distribution. As granules, compared with powdered or crystalline unit fertilizers, it has a compact structure, uniform nutrient release, and a stable, long-lasting fertilizer effect, with little adverse impact on the soil.
Excellent physical properties
The compound fertilizer is made into granules in one batch, giving it low hygroscopicity. This makes it resistant to clumping, and easy to store and apply.
Formulation specifications
Nitrogen, phosphorus, and potassium ratios are precisely adjusted according to the grain growth cycle, such as the high-nitrogen formula commonly used in corn.

Crop suitability & application notes
Well suited to hemp and broadacre field crops, with important precautions for chloride-sensitive cultivars.
Ideal for hemp and field crops Suitable for aquatic vegetables, hemp crops and field crops. MOP-based compound fertilizers, whose potassium comes from muriate of potash (MOP), are particularly suitable for hemp crops. They can also be used for rice, wheat, corn, millet, sorghum and soybeans.
Application precautions MOP-based compound fertilizers may have adverse effects on some chloride-sensitive crops because they contain a large amount of chloride. During production, MOP-based compound fertilizers do not remove the chloride that is harmful to chloride-sensitive crops, resulting in a high chloride content in the product. Chloride ions remaining in the soil may cause soil compaction, salinization and alkalization, deteriorating the soil environment and reducing the nutrient absorption capacity of crops.
