Hi-Cote is a specialized fertilizer covered with a material that facilitates the gradual release of nutrients, ensuring a continuous and optimal nutrient supply throughout the plant's growth period.

Key Features

• Solid and uniform polymer coating allows for precisely controlled nutrient release over time.
• Suppresses early nutrient release to prevent seed damage caused by N (Sigmoid type).
• Customizable formula available for varying temperature and moisture level up to 360 days.
• Decreases nitrogen leaching and volatilization.
• Available with DAP, MAP, SOP, MOP, and urea.


(Polymer Coated Urea)

• Nitrogen content
– Linear 42 ~ 43%
– Sigmoid 38 ~ 39%
• Coating Color : Various
• Granule Size : 3 ~ 4.5mm
• pH : 7.0
• Hardness : 3kg/f

Why Should use CRF?

Quality control

• Precise and uniform coating technology
• Guaranteed longevity (according to plant needs)

High Fertilizer Utilization and
Economical Efficiency

• Increases utilization by reducing fertilizer loss (leaching, volatilization, etc.)
• Reduces total fertilizer use

Labor Saving

• One time application provides all NPK requirements until harvesting
• Eliminates the need for additional top dressing


• Reduces groundwater pollution
• Reduces greenhouse gas emission

How do CRFs work?

Nutrient release of the CRF occurs in three steps: Moisture penetration into the capsule; Fertilizer Dissolution; Nutrients release by osmotic pressure. When granules are applied to the soil, water penetrates into the granules and dissolves nutrients, which are later gradually release into the soil. The coating material controls water penetration and availability of nutrients in forms preferred by plants, that result in maximizing crop yields. Compared to slow release fertilizer, CRF is not affected by soil pH, salt damage, activity of microorganisms, oxidation, etc.

Coating Process

The CRF Coating Process involves spraying of coating material onto a fertilizer granule, resulting in the formation of a coating capsule. The uniformity and accuracy of Nousbo CRF are achieved through the application of a special coating technology.
