Water-Soluble Calcium (WS-Ca)

Calcium is as important to plants as it is to humans. It is one of the most common substances in the world next to oxygen and silicon and the majority of calcium exists in the form of calcium carbonate (CaCO3). In Natural Farming, calcium carbonate is extracted from egg shells in which calcium carbonate is the main component by using brown rice vinegar. Through this process, calcium carbonate is changed to water-soluble calcium, which can be quickly absorbed by the crop. It prevents overgrowth of crops, hardens the fruit, prolongs storage period, promotes absorption of phosphoric acid and helps crops to accumulate nutrients. Calcium in water soluble form is efficient and effective in natural farming. Eggshells are very cost-effective materials for WS-Ca.

Calcium contributes to better utilization of carbohydrates and protein. It is the major component in forming cell membranes and enables smooth cell division.

Calcium removes harmful substances in the body by binding with organic acids.

Calcium prevents crops from overgrowing.

Calcium makes fruits firm and prolongs the storage period.

Calcium promotes absorption of phosphoric acid and is responsible for nutrient accumulation in the crop.

Calcium plays a very important role in maintaining the health of the plant.

Calcium carries and accumulates nutrients for e.g., carbohydrate, which are temporarily stored in branches and in leaves till the final storage organ for e.g., ovary through physiological activity.

Eggshells / Seashells

Crushing / Pounding Tool

Brown Rice Vinegar (BRV)

Jar / Polyethylene container

Porous paper ( PaperTowel)

Rubber band / Thread Calcium carbonate is the main component of eggshells. When calcium carbonate acts with any kind of acid, it produces carbon dioxide (CO2). But acetic acid, the major component of vinegar, is a weak acid, so it reacts very slowly and emits an imperceptible amount of CO2. A fluffy egg shell means that CO2 is melting into vinegar.

Collect eggshells and take out the inside peel. Taking out the inside peelings clears the eggshells of matters other than calcium.

Crush / Pound the shells in to small pieces (not into powder form). This makes the process faster and the product more effective.

Lightly roast the shells to remove any organic substances that may rot and deteriorate during the process.

Put the roasted shells in a container filled with brown rice vinegar (BRV). The eggshells will move up and down, emitting bubbles and melt to become a neutralized liquid. When there is no more movement or bubbles, it is done. When there are no more bubbles with the added eggshells, it means the solution is saturated.

PRECAUTION: Put the roasted eggshells little by little and slowly into the container with veniger or BRV. If not, the bubbles can overflow by the reaction between the materials and the BRV.

NOTE: The eggshells that still have calcium carbonate may sink and remain at the bottom. This is because there are too many materials for the veniger or BRV to melt and the solubilization process reaches the saturation point. In this case, take out the solution and add more veniger or BRV.

WS-Ca is used with WCaP, FPJ, OHN and sea water for better taste and more aromatic fruits. It is sprayed on the leaves after the fruits have become large. Use after dilution with water. The basic dilution ratio is 1:1000

Several WS-Ca completed separately may be mixed in order to enhance the effect of calcium.

WS-Ca is very effective in the cross-over period when the growth of crop changes from vegetative to reproductive growth.

Spray WS-Ca on the leaves several times after the fruits have become large to some degree. Spraying WS-Ca prevents plants from overgrowing and yields solid fruits.

WS-Ca leads nutrients to be accumulated in flower buds and fruits. As a result, the flower buds become strong, can prepare for high yields the following year and harvest solid and substantial fruits that year as well.

WS-Ca has an effect of improving the taste and fragrance of the fruit when it is used with water-soluble calcium phosphate, oriental herbal nutrient (OHN), fermented plant juice(FPJ) and sea-water.

Use WS-Ca when the plants overgrow.

Use WS-Ca when the initial growth of the crop is poor.

Use WS-Ca when the leaves discolor and lack luster

Use WS-Ca when the flower buds have poor differentiation.

Use WS-Ca when the physiological drop is severe.

Use WS-Ca when fruit enlargement is slow

Use WS-Ca when the sugar content decreases.

WS-Ca helps in the transition from vegetative to reproductive growth. It is also effective when crops are overgrown, leaves have bad color or no luster, floral differentiation is weak, flower blossoms just fall, fruits do not ripen, fruits are not sweet and crops are nitrogen-excessive. However, WS-Ca should not be given when vigorous vegetative growth is needed.

The optimum temperature should range from 23-25 °C.

It is good to have cool and shaded place where no direct sunlight can penetrate.

Underdeveloped roots and feeble root hairs: It is because, the normal protoplasm of the cell is not formed due to calcium deficiency.

The leaves discolor become brownish and then dry out.

Appearance of empty bean pods.

Poor ripening of the fruit and vegetable, excessive moisture and organic acid, lack of sugar content, softening of the fruit flesh, insufficient fragrance.

Leafy vegetable contact with Rhizoctonia disease and the poor heading phenomenon.

Root vegetables become pithy(spongy) and hollow, lack of sugar content and fragrance and it stay a short time in storage.

Both rice plants and barley plants suffer from problems such as excessive moisture, low accumulation of starch, lack of luster and fragrance and low resistance to insects and diseases.
