What is the primary benefit of carbon dioxide enrichment in a greenhouse setting?

The primary benefit of carbon dioxide enrichment in a greenhouse setting is that it enhances photosynthesis. Plants use carbon dioxide as a critical ingredient in the photosynthesis process, where they convert light energy into chemical energy, producing oxygen and glucose. By increasing the concentration of carbon dioxide in the greenhouse, it allows plants to photosynthesize more efficiently and at a faster rate. This often leads to improved growth rates, higher yields, and better overall health for the plants, as they have more of the necessary raw material to drive this essential process.

While enriching carbon dioxide can influence plant temperature indirectly by enabling faster growth, it does not directly increase temperature in the way heating systems do. Similarly, carbon dioxide enrichment does not specifically target pest reduction or soil quality improvement, which are influenced by other factors such as pest control measures and soil management practices. Thus, the enhancement of photosynthesis is the most significant and direct benefit of carbon dioxide enrichment.
