Carbon Dioxide Fertilizer to Promote Growth
Carbon dioxide is essential to plants as oxygen is essential to humans and animals. Humans and animals inhale oxygen produced by plants and exhale carbon dioxide that is used by plants to support photosynthesis. Photosynthesis is a process carried out by plants in order to prepare ‘food’ with the presence of sunlight, chlorophyll and carbon dioxide.
An efficient photosynthesis rate is needed for the plants to be able to grow to their full potential. Naturally, plants need 0.1 to 1.0 % volume of carbon dioxide to reach their optimal photosynthesis rate. However, the surrounding air contains only 0.03 % of carbon dioxide that is available for photosynthesis. Therefore, plants are unable to reach their maximum growth due to the lack of carbon dioxide. This results in smaller plants, leaves and fruits.
In order to ensure optimum growth, carbon dioxide has to be supplied to the plants. In the 1920s, carbon dioxide gas was supplied directly to the plants. Pipes were built along with the plants. Carbon dioxide gas would be slowly released from the pipes to be absorbed by the plants. However, the situation was difficult to control as there is the runoff of the carbon dioxide into the environment.
In current days, fertilizer in the form of calcium carbonate is available to the consumers. This type of fertilizer is usually a slow release. Once applied, the granules slowly release carbon dioxide over a long period of time, just enough for the plants’ stomata to absorb some carbon dioxide to assist photosynthesis, and avoid wastage and environmental poisoning. The extra source of carbon dioxide enables plants to produce a higher yield of fruits and also larger and healthier fruits.
