Got Calcium?

There is an old wives' tale that says to "let pumpkin tendrils sip milk from a saucer". Common belief holds this originated with the idea that milk can be used to combat calcium deficiencies.

But don't raid the refrigerator just yet. The calcium and phosphorus in milk are bound into molecules too large to penetrate even the most receptive leaf. Still, there IS a kernel of truth to this tale.

Calcium is critical for plant development. In fact, by weight and volume, plants need it more than any other element:

  • Calcium is the chief determinant of cell wall and membrane strength, and it improves a plant's vigor and stiffness.
  • Calcium is critical for healthy plant growth and cell division.
  • Calcium improves a plant's ability to resist disease.

But to be effective, efficient and available to plants, calcium needs to be chelated. Chelating micronutrients such as calcium makes them more mobile in soil and in plants, makes them less prone to leaching, and prevents them from becoming locked-up by inhospitable pH levels in the soil. When applied as a foliar spray, chelated calcium - unlike unchelated calcium - is able to rapidly penetrate a leaf's waxy coating and enter into the plant, working to quickly correct deficiencies.

Growth Products' Cal-Tech 9% liquid solution is 100% chelated, so that it's immediately available for plant uptake. It also provides dual efficiency, since the calcium can be absorbed via the leaves and the roots of the plant.

• 100% Chelated Calcium

• Quickly Corrects Calcium Deficiencies

• Soluble & Ready For Immediate Uptake

• Use To Raise pH Levels



Calcium Chelate 9% is fully chelated micronutrient for the correction of calcium deficiency in field crops, fruit trees and greenhouse crops. This convenient clear liquid is recommended for foliar spray or soil applications and provides calcium in a soluble, readily available form for plant uptake. Calcium can correct minor deficiencies or can be used in a regular growing program where crops and soils are known to be deficient. It is important to treat calcium deficiency before the symptoms become visual to insure proper crop yield. Rates of Calcium will vary depending upon the severity of the deficiency, climate, soil conditions and method of application. Soil analysis can determine pH and available calcium. It is compatible and can be used with most fertilizers and technical materials. Calcium promotes early root formation and growth, improves plant vigor and fruit integrity and helps control cork spot and bitter pit on apples and pears. Calcium influences the uptake of other nutrients, encourages grain and seed production. Use in hot weather to reduce heat stress.


 When determining the application rates of Cal-Tec 9%, it is important to check both tissue and soil sample analysis for calcium levels. Since calcium is the second highest percentage in plant tissue, it is important to correct any deficiencies early in the spring and continue to apply throughout the growing season. Hot weather will also aggravate calcium deficiencies. Calcium deficiencies become evident at terminal bud growth, with hooked malformation and finally dying back.

  Like all Growth Products, it is ideal for any type of hydroponics, fertigation system, drip irrigation or foliar spray equipment. Use Ca-Tec on all types of bedding plants, perennials, cut flowers, plugs, ornamentals, nursery crops, trees, foliage, ornamental grasses, and container plants.

Direct Siphon: Cal-Tec can be siphoned directly from the original container. This can be done with a variable proportioner that can be set to high ratios. This eliminates the need to mix stock concentrates or stir the mixing barrels. For 100 PPM calcium, set injector to 1:1000; for 200 PPM, set injector to 1:500.

Soil & Tissue Testing:

 Have horticulturists identify micronutrient deficiencies. Whenever possible, run these tests prior to micronutrient applications in order to prescribe the deficient micro. Foliar Feeding: When using overhead irrigation, Cal-Tec gives you dual efficiency as the nutrients will be absorbed by both the leaf and roots of the plant. For tender plants and greenhouse foliar spray applications use one-half the rate (PPM) you would normally use for drip irrigation feeding. Hand Watering: Mix ½ to ¾ teaspoon Cal-Tec per gallon of water. Saturate soil with mix.


Foliar Application:

  Dilute with water according to label recommendations to apply as a foliar spray. Always spray on leaf until run-off. See chart for crop rates. For conventional sprayers use a minimum of 20 gallons of water per acre (200 L of water per Ha). For best results spray in early morning or late afternoon. Do not spray in the heat of day. For best results spray when the crop is in an active growth state, after irrigation or natural rainfall.

Deficiency Symptoms:

Terminal bud growth will be hooked or distorted. Leaves have a wrinkled appearance.
