1. Natural chelating agent therefore high acceptance by plants.

    2. Quick absorption & delivery of Calcium to tissues where it is required.


  1. Water Soluble Calcium (CaO):- 9%; Water Soluble Boron:- 1%.
  2. Chelating Agent- Heptagluconic Acid: 100%
  3. Colour: Light Brown
  4. pH: 2.3
  5. Density: 1.3 g/cc
  6. Free from chloride, sulfate, and nitrate.
  1. It is immobile & remains in older tissue.
  2. Calcium is a primary constituent of cell walls & membranes and is involved in production of new growing parts & root tips.
  3. Deficiency of Calcium will adversely affect cell division; impair structural stability & permeability of cell walls.
  4. Increase of Calcium in Fruit, promotes longer storage life & resists a range of Physiological breakdown conditions (such as water core, Bitter pit, internal browning in Apples, Tip burn in Lettuce, Internal Rust spots in Potatoes & Blossom End Rot in Tomatoes, Bud Necrosis in Grapes) etc.
  5. Due to stronger cell walls provided to the plant by Calcium, Fungal spores are less likely to penetrate and germinate in host cells.
  6. Crops that suffer from diseases like Botrytis, Rhizoctonia, Phythium, & Fusarium can have greater resistance to such fungal attacks
  1. Excessive dry or wet soils
  2. Excessive Potash in soils
  3. Upper leaves are distorted & curled at edges
  4. Leaves may have yellow bands
  5. Leaves may turn brown & die.
  6. Roots develop poorly , are short & chubby and turn brown at an early age and have few root hairs
  7. The leaves of some plants hook downward and exhibit marginal necrosis
  8. In blossom end rot, pale brown sunken areas will develop around blossom end. (e.g. Tomatoes).
  9. Flower buds will fail to develop
  10. In case of Grapes. Calcium deficiency creates bud Necrosis in Grape bunch
  1. Slow root development. Roots may develop a dark color and in severe cases the growing point may die.
  2. New leaf growth may slow and leaf tips may stick together. Remember that calcium does not readily translocate within the plant. So deficiency symptoms will appear on the new growth.
  3. Poor nodulation by nitrogen fixing bacteria on leguminous plant roots. Ineffective nodules are white to grayish green inside while healthy nodules have dark pink interiors.
  4. Blossom end rot in tomatoes. Calcium and proper water management improve plant resistance to this problem.
  5. Aborted and shriveled fruit on peanuts. A shortage of calcium at "pegging" results in a high percentage of "pops".
  6. Darkened plumule or "black heart" in peanut seed. This reduces yield, quality and crop value.
  7. Pod rots diseases on peanuts. Pods are predisposed to fungus infections when calcium is deficient or out of balance with Mg and K.
Crop Recommendation No of applications & timing
Apples To Prevent Bitter pit 5 applications beginning at petal fall
Grape Improved fruit finish & storage 5 applications from beginning of berry setting to maturity
Oranges To increase fruit firmness 2-3 applications
Strawberry To increase fruit firmnesst 3 applications
Cabbage Lettuce Cauliflower To Prevent Tip burn 2 –3 applications starting at head formation
Cucumber, Melons, Capsicum, Tomatoes To Prevent Blossom end rot 3-6 applications from flowering & in times of heat stress
Potatoes To Prevent Internal brown spot 3-6 applications from flowering & in times of heat stress
Apples To Prevent Bitter pit 5 applications beginning at petal fall
Onion To Prevent Tip burn. To obtain Larger Onions with better storability 6 leaf stage onward 2-4 sprays
Vegetables To get crisp and firm vegetables with shiny appearance 2 sprays at flowering to fruiting
Groundnut To improve quality & yield 2-3 sprays beginning pegging
Leafy vegetables For freshness and shiny appearance 1 spray 8-10 days before harvest
Ornamentals To increase Vase life Weekly application with Pesticides
  1. It is free from Chloride, Sulfate and Nitrogen, and therefore ideal for crops during fruiting, Flowering & in periods during maturity
  2. Ideally applied as a foliar fertilizer, CALBON is directly absorbed by leaves, Shoots and fruits.
  3. CALBON will also have a favorable effect in reducing sun damage.
2 ml/Liter for foliar application.
  1. Not for Human / Medicinal use
  2. Keep away from Eyes & Skin
