(1) Soil moisture penetrates the polymer coating within a week and activates the encapsulated 

      nutrients.

(2) No nutrient is released.Nutrients slowly diffuse through the polymer coating over the next

      several months when triggered by soil temperature.

(3) The polymer coating microbially decomposes into naturally occurring soil elements after

      complete release of nutrients.;

 

The advantages of controlled release fertilizers are as follows:

1. Fertilizer burn is not a problem with CRFs even at high rates of application

2. Fertilizers are released at a slower rate throughout the season; plants are able to take up most of the fertilizers without waste by leaching

3. Less frequent application is required

4. Uniform particle size allows easier and precise mechanical distribution

5. Flexibility of release periods from 40 to 360 days at 25C

6. Reduced capital and labour outlay in horticultural crop production

7. Reduced nutrient loss via leaching and run-off thus reducing environmental damage

8. Reduced seed or seedling damage from high local concentrations of salts

9. Reduced leaf burn from heavy rates of surface-applied fertilizers

10. Improved storage and handling properties of fertilizer materials

11. Product differentiation resulting in improved market potential

12. Reduced Greenhouse Gas Emission from transportation of fertilizersThe advantages of controlled release fertilizers are as follows:

 

Products

The coating material employs the latest specially developed solventless polymerization technology to coat high quality fertilizers with a thin layer of water impermeable coating. The Cote series can be further differentiated to the following:

• Cote Precise: Fully coated controlled release NPK fertilizers with balanced nutrition.

• Cote Plus: Controlled release NPK fertilizers blended with instant release fertilizers.

• Cote Single: Premium single element controlled release fertilizers.

 

Cote Precise

Cote Precise consists of premium polymer coated fertilizers which provides longevities from 40 days to 365 days.
