Greenhouse CO₂ Enrichment

Greenhouse CO₂ enrichment is the practice of increasing the concentration of carbon dioxide (CO₂) in a greenhouse to enhance plant growth and improve crop yields.

CO₂ enrichment is important because carbon dioxide is a key component of photosynthesis. Increasing CO₂ levels can significantly enhance plant growth, leading to higher yields and improved quality of crops.

The primary gas used for greenhouse CO₂ enrichment is carbon dioxide (CO₂). In some cases, other gases like nitrogen (N₂) may be used for specific purposes such as creating an inert atmosphere for certain crops.

Benefits include increased plant growth rates, higher crop yields, improved plant health, enhanced resistance to pests and diseases, and more efficient use of water and nutrients.

Safety considerations include ensuring proper ventilation, monitoring CO₂ levels to avoid excessive concentrations, and following safety protocols to prevent asphyxiation and other hazards.

Effectiveness is monitored by regularly measuring CO₂ levels using sensors and controllers, observing plant growth and health, and adjusting CO₂ delivery systems as needed to maintain optimal concentrations.

Crops that benefit most include tomatoes, cucumbers, peppers, lettuce, strawberries, and various ornamental plants. Most greenhouse-grown plants respond positively to increased CO₂ levels.

Yes, other gases such as nitrogen may be used to create specific growing conditions or to inert certain environments. However, CO₂ is the primary gas used for enrichment purposes.
