Product Overview

Key Features

The core of our product is the Dual-Action calcium delivery system.
This proprietary formulation technology simultaneously maximizes the long-term stability of available calcium and the immediate absorption rate for crops.

01. Core mechanism Slow-Release Calcium

Advanced Organic Chelation Technology

Our bio-based organic compounds form chelated bonds with calcium ions.
This bonding prevents calcium immobilization in the soil and ensures a continuous, stable supply of calcium precisely when the crop demands it.

02. Sub mechanism Fast-Acting Calcium

Contains Immediate Water-Soluble Calcium

The water-soluble calcium integrated within our formulation is engineered for rapid absorption immediately after application.
It provides an immediate response during early growth stages or in situations of acute calcium deficiency.

03. Basic mechanism Soil Activation

Soil Microbial Activation

Manufactured with a natural organic base, our product serves as a soil amendment for degraded land and activates underground microbes, transforming the soil into a fertile environment optimized for crop growth.

Core Technology

Rhizosphere Ligand Exchange

Intelligent Calcium Delivery System

Our proprietary RLE technology is engineered to release calcium only at the time and location required by responding to the physiological signals of the crop.

The organic matrix structure prevents the immobilization of calcium within the soil, minimizing the loss of effective calcium.

Crop roots secrete root exudate as a biological signal; this signal induces
a ligand exchange reaction, enabling the direct release and absorption of
calcium ions within the root zone (rhizosphere).

Organic Matrix

Functions as a protective barrier
to prevent calcium immobilization
in the soil.

Root Signal Detection

Root Signal Detection
Recognizes root exudate
as a biological signal.

Ion Exchange

Releases calcium ions into the root
zone through ion exchange

Application Guide by Crop Type

Crop Application Rate
Kg/10a(1,000㎡)
Application Method
Rice
(Reclaimed Land)
200~250
(250~300)
Apply by broadcasting immediately after harvest or after the thawing season, followed by deep plowing.
For reclaimed land, apply an additional 50kg compared to the dosage for standard paddy fields.
Fruit-bearing Vegetables 200~300 For watermelon, strawberry, oriental melon, cucumber, pumpkin, pepper, tomato, and bell pepper, broadcast 14 days before transplanting, followed by deep plowing.
Fruit Trees 200~300 For peach, apple, pear, grape, citrus, and persimmon, apply during the winter management period, followed by deep plowing.
Root Vegetables 150~300 For carrot, radish, ginger, potato, sweet potato, and bulbous medicinal herbs, broadcast 14 days before sowing, followed by deep plowing.
Leafy Vegetables 200 For napa cabbage, cabbage, spinach, lettuce, and leek, broadcast 14 days before sowing or transplanting, followed by deep plowing.
Turf/Lawn 200 Broadcast 14 days before sowing, followed by deep plowing. Small amounts of top-dressing can also be applied during spring, summer, and fall.
Floriculture/Flowers 150~200 For roses, chrysanthemums, carnations, and lilies, broadcast 14 days before transplanting, followed by deep plowing.
Greenhouse Cultivation 150~200 Apply 10~20% less than the dosage for open-field crops. Apply by broadcasting, followed by deep plowing.

*Due to the characteristics of slow‑release fertilizers, a distinctive lipid‑like appearance (color) may be visible after application. Maintaining adequate moisture after incorporation can further enhance its effectiveness.

Precautions for Use

  1. Mixing with organic fertilizers, compost, lime-based fertilizers is permissible. Consult the supplier to determine the appropriate application rate.
  2. For consecutive annual applications, consult with your distributor to determine the appropriate dosage before use.
  3. Providing sufficient water after application can help improve nutrient uptake.

Storage Precautions

  1. Store in a cool, dry place away from moisture and direct sunlight.
  2. Handle with care to prevent tearing or damage to the packaging.
