CO2 Enrichment

• A plant's rate of photosynthesis and growth rate and quality can be increased by increasing CO2 levels
• During the day, CO2 levels can decrease greatly due to photosynthesis
• CO2 cannot penetrate the greenhouse, it is a fairly closed system
• CO2 enrichment can occur on a large scale by pumping CO2 gas from tanks into the greenhouse
• Adding sodium bicarbonate, and organic materials to soil, will increase CO2 levels
• Decomposition bacteria in the soil will become more active and CO2 will be released during decomposition
