Carbon dioxide enrichment

Carbon dioxide enrichment refers to the process of increasing the concentration of carbon dioxide (CO2) in the atmosphere or a specific environment to promote plant growth. This method is commonly used in controlled environment agriculture, including greenhouses and indoor farming, to enhance crop yield and quality.

Overview

Photosynthesis is the process by which plants convert light energy, usually from the sun, into chemical energy in the form of glucose. Carbon dioxide, along with water, is a key input in this process. By increasing the concentration of carbon dioxide in the environment, the rate of photosynthesis can be enhanced, leading to faster plant growth and higher crop yields.

Methods of Carbon Dioxide Enrichment

There are several methods of carbon dioxide enrichment, including the use of bottled CO2, CO2 generators, and CO2 pads. The choice of method depends on various factors such as the size of the growing area, the type of crop, and the grower's budget.

Bottled CO2

Bottled CO2 is a common method of carbon dioxide enrichment, especially for smaller growing areas. The CO2 is released from the bottle into the growing area through a regulator and a distribution system.

CO2 Generators

CO2 generators produce carbon dioxide by burning propane or natural gas. They are suitable for larger growing areas and can produce a high concentration of CO2.

CO2 Pads

CO2 pads are a newer method of carbon dioxide enrichment. They release CO2 when water is added to them. This method is easy to use and does not require any special equipment.

Benefits of Carbon Dioxide Enrichment

Carbon dioxide enrichment can significantly increase the yield and quality of crops. It can also make plants more resistant to diseases and pests. However, it is important to monitor the concentration of CO2 in the growing area to ensure that it does not exceed safe levels.
