Cera-coatR

Features and Types of Cera-coatR

We have seven Cera-coatR products, ranging from R25 to R130. R25 is a linear type product which begins releasing ingredient immediately after the fertilization, while, the other six products, R30 to R130, are designed to hold the release for a certain period of time before those fertilizer start releasing ("sigmoid type").

We use vegetable oil based polyurethane resin, main ingredient of which is a natural raw material, to coat Cera-coatR. After release is completed, the coating will be gradually dissolved and decayed by sunlight and microbes.

The coating of Cera-coatR has execellent impact resistance feature so that its release performance is not effected by mechanical fertilization.

Table 1 Cera-coatR Series

Product Guaranteed nitrogen content (%) Release type Release control (number of days) Release (number of days)
R25 42 Linear type - 25 days
R30 41 Sigmoid type 15 days 30 days
R50 41 Sigmoid type 25 days 50 days
R70 41 Sigmoid type 35 days 70 days
R90 41 Sigmoid type 45 days 90 days
R110 41 Sigmoid type 55 days 110 days
R130 41 Sigmoid type 65 days 130 days

Notes

*Release control(number of days) and Release(number of days) are the number of days, which are required to release 10% and 80% of nitrogen,respectively, in 25°C water.

Cera-coatR Compound Fertilizer

One of the features of Cera-coatR compound fertilizer is to be able to supply the soil with appropriate amount of nitrogen when the crops need it. As Cera-coatR compound fertilizer is so efficient that users are able to reduce the amount of fertilizer applied, consequently, fertilizer runoffs to rivers and ponds will be minimized.
Furthermore, after the initial fertilization as base, Cera-coatR compound fertilizer works long enough to reduce time and labor related to additional fertilization. Insomuch that the production cost is reduced.
We have a wide variety of Cera-coatR compound fertilizer products, depending on geographical features, such as cold, warm weather and in-between regions.
In the result, in cold regions, we mainly use Cera-coatR (B) and (C), which are designed to release ingredient quickly, and in warm regions, Cera-coatR (D), (E) and (F), the release of which is relatively slow.
