Fruit Growing Stage Nutrition : Provides adequate and balanced nutrition during the growing stage, supporting uniform growth and stronger rooting.
One Time Application : Single application delivers all required nutrients throughout the growing season — no additional top dressing needed.
Labor & Cost Saving : Eliminates repeated fertilization, reducing labor time and overall input costs.
Precise Nutrient Release : Polymer coating controls water penetration and nutrient availability in forms preferred by plants, maximizing crop yields.
Nutrient | Amount |
|---|---|
Nitrogen (N) | 23% |
Total Phosphate (P₂O₅) | 5% |
Total Potash (K₂O) | 12% |
HI-COTE Fruit offers two release curve types to match nutrient delivery to specific cultivation environments and growing schedules.
Linear Type | Sigmoid Type | |
|---|---|---|
Release pattern | Consistent, steady release throughout the entire growth cycle | Slow start → rapid mid-stage release → gradual end, following crop growth pattern |
Available options | L40 / L70 / L100 / L180 / L270 | S60 / S100 / S140 / S160 / S200 |
Best for | Stable growing conditions requiring uniform nutrition | Environments where nutrient delivery timed to crop growth stages is preferred |
Linear Type
Longevity Option | Release Characteristic |
|---|---|
L40 | Fast release — ~80% nutrients released within 40 days |
L70 | Moderate-fast release — ~80% within 70 days |
L100 | Standard release — ~80% within 100 days |
L180 | Extended release — ~80% within 180 days |
L270 | Long-term release — ~80% within 270 days |
Sigmoid Type
Longevity Option | Release Characteristic |
|---|---|
S60 | Fast sigmoid — rapid surge from day 20, ~80% by day 60 |
S100 | Standard sigmoid — surge from day 30, ~80% by day 100 |
S140 | Moderate sigmoid — surge from day 40, ~80% by day 140 |
S160 | Extended sigmoid — surge from day 50, ~80% by day 160 |
S200 | Long-term sigmoid — surge from day 60, ~80% by day 200 |
Linear type : Provides a consistent release of nutrients throughout the entire growth cycle. Sigmoid type : Controls nutrient release amount following a crop's growing stage — slower at establishment, higher during active growth, tapering at maturity.
Step | Description |
|---|---|
① Moisture Penetration | Water penetrates into the polymer-coated capsule |
② Fertilizer Dissolving | Nutrients dissolve inside the granule |
③ Nutrients Release | Dissolved NPK is gradually released into the soil by osmotic pressure |
Unlike slow release fertilizers, CRF is not affected by soil pH, salt damage, microorganism activity, or oxidation — ensuring stable and predictable nutrient availability.
Benefit | Description |
|---|---|
Quality Control | Precise and uniform coating technology with guaranteed longevity according to plant needs |
Labor Saving | One-time application provides all NPK requirements until harvesting, eliminating additional top dressing |
High Fertilizer Utilization | Reduces fertilizer loss from leaching and volatilization, lowering total fertilizer use |
Eco-friendly | Reduces groundwater pollution and greenhouse gas emissions |
