This study also “compare(d) carbon sequestration to nitrous oxide and carbon dioxide emissions from lawn grooming practices.”
I have news for anyone willing to listen. Lawn maintenance doesn’t produce carbon “di”oxide emissions. Lawn maintenance produces carbon “mon”oxide. Carbon monoxide produces carbon dioxide which in turn is used by plants during photosynthesis to make sugars. I’m gonna take a stab in the dark and say this is what the tested lawns were doing while being tested. CO2 makes up only 0.038% of the atmosphere.
Proper maintenance is the key to a healthy, viable and beneficial lawn. Bloviation of hot air is not.
