Description

A CARBON DIOXIDE SOURCE
Technical Field
The present invention relates to a carbon dioxide (CO2) source supplying carbon dioxide required for a plant to grow by being embedded in the soil environment of said plant.
Prior Art
Soilless agriculture or aqueous (hydroponic) agriculture are methods of cultivation applied in a suitable water culture without using soil. In such agricultural methods, the plants use a nutrient solution containing the required minerals instead of nutrients in soil. Therefore, rather than seeking minerals from the entirety of soil, the plants can acquire the nutrients easily and directly from a nutrient solution. In order to support the plants and their root systems, cultivation environments are used such as sand, turf, vermiculite, perlite, coconut, rock wool, cotton, felt or expanded clay aggregate, which have a high tendency to restrain humidity around the roots. The cultivation environment itself is not a nutrient source. There is a gradual increase in the number of greenhouse areas utilizing such agricultural methods. Arcelik is a company devising plant growing cabinet applications in which cabinets and cultivation environments are designed combining temperature, humidity, illumination and nutrient conditions in accordance with soilless agriculture principals.
Carbon dioxide (CO 2 ); Appropriate ventilation of plant roots and favorable ventilation conditions thereabout enhances a healthy plant growth. During photosynthesis, plants take in carbon dioxide and deliver oxygen. Although it is assumed that the plants respire only with their leaves, the plants in fact respire also with their roots and stems. In addition, the minerals or gasses received through the roots are rather significant in plant growth. Normal growth begins by an oxygen rate more than 10% in root environment and new root growth begins by an oxygen rate more than 12%. The carbon dioxide rate in root environment should be below 1% for optimal growth. Presence of hydrogen sulfide and methane gasses forming due to anaerobic respiration is harmful for plant roots. In soil agriculture, various chemicals are introduced into soil for CO2 formation and CO2 is given to soil by various equipment. Whereas, for aqueous agriculture, CO2 bottles are used in enclosed/controlled cabinets or greenhouse-like environments. CO2 gas introduced into water by risky and costly methods in a controlled manner. CO2 gas is of utmost importance for a plant 50% of which is carbon. Even though they receive CO2 through their leaves, acquiring CO2 also through the roots enables plants to have greener and stronger roots.

Brief Description of the Invention
The aim of the invention is to emit carbon dioxide for growth of a plant by utilizing various methods which are low cost, controllable, without risks and using natural resources.
Another aim of the invention is producing CO2 gas in natural conditions without using a CO2 bottle unlike traditional applications.
Detailed Description of the Invention
The carbon dioxide source of the invention comprises an absorbent material acting as a bearer, and a carbonate material used for supplying carbon dioxide (CO2) within said absorbent material, and emits gaseous CO2 into the soil of a plant into which it is embedded as a result of said carbonate material reacting with an acidic solution.
In an embodiment of the invention, said carbon dioxide source comprises an absorbent material with a gel mesh structure and a carbonate material entrapped within said gel mesh structure, and is formed by mixing a water-soluble carbonate material into a synthesis solution during synthesizing of an absorbent material.
In another embodiment of the invention, the carbon dioxide source of the invention is formed by dissolving a carbonate material in a nutrient solution, and impregnating thereof together with water into ready-made absorbent material granules, powder or particles.
In an embodiment of the invention, carbonate salts, bicarbonate salts or at least one carbonate salt consisting of a mixture thereof is used as the carbonate material.
In an embodiment of the invention, at least one material selected from the group comprising of superabsorbent polymers, hydrogels and zeolites, is used as the absorbent material.
The carbon dioxide source of the invention is formed by mixing a water-soluble carbonate or bicarbonate like material into a synthesis solution during synthesizing of an absorbent material. As a result of gelling and polymerization process occurring during synthesizing phase, the carbonates are trapped within a gel mesh structure. Granule form absorbent material with carbonate content is thus obtained
In another production method, the carbon dioxide source of the invention is produced by dissolving carbonate or bicarbonate in a nutrient solution, and impregnating thereof together with water into ready-made absorbent material granules, powder or particles. The absorbent materials may be superabsorbent polymers, hydrogels or zeolites. Such hydrophilic materials are advantageous in that they are able to contain carbonates enabling CO2 gas emission as well as supporting plant roots.
A water solution comprising acetic acid such as vinegar is introduced to the bearer with carbonate obtained by either method. As a result of the reaction between carbonate and acid, carbon dioxide gas is emitted as can be seen in the following reaction equation (Formula 1).
Formula 1 displays the equation of the reaction which occurs when sodium bicarbonate is used as the carbonate material and acetic acid solution is used as the acid solution within the scope of the invention.
NaHCO3(s) + CH3COOH(l) → CO 2(g) + H2O(l) + Na+ (aq) + CH3COO- (aq)
The released carbon dioxide emits to the environment in gas particles, thereby enabling giving CO2 to the plant through its roots.
The most significant characteristic of the carbon dioxide source of the invention is its risk free structure with respect to the other applications known in the art, and producing CO2 gas in natural conditions without using a CO2 tube. The fact that the invention does not require any additional equipment or system compared to the other methods, it provides a cost advantage and enables a plant to receive CO2 gas by producing and emitting said gas in natural conditions. In addition, the gas is produced by means of materials such as carbonate and vinegar which are natural, readily-available in every household and health-wise completely harmless. Preferred as a natural and harmless material as noted above, vinegar (acetic acid) is known to have antibacterial properties, and helps growing healthier and stronger plants by disinfecting the roots from likely formation of mold and bacteria therein. The pH level of basic tap water which is one of the greatest problems in aqueous agriculture, is reduced thanks to the invention, to acidic 5.5-6.5 levels and is maintained constant at these pH values by using vinegar (acetic acid).
