Have read lots of blogs over the years in regards to the effect of CO2 on plant growth. Most people know that hothouse plants (tomatoes,cucumbers) are grown at levels of CO2 up to 1200ppm. This compares to atmospheric concentration of around 400ppm. CO2 generators use natural gas that also heat the greenhouses. So, can it be used for turf? Found this company that uses finely ground minerals that are sprayed on turf as a very fine pattern. The minerals, not sure what they are find their way into the stomata and release CO2. CO2 is needed for photosynthesis and helps to make the plant grow better. Stomata can stay smaller since there is enough CO2 and so do not respire as much saving water.
Found the company through Google with the following links:

A long and an older presentation on plants and CO2---a little dry-like some seminars I've been to!
