Greenhouse gas (GHG) emission has become an
important issue on the world's agenda due to their impact on global warming and
climate change. Agricultural activities are the main source of the entry of the
three main greenhouse gases, carbon dioxide (CO2), methane (CH4)
and nitrous oxide (N2O), into the atmosphere through direct and
indirect emissions. Important greenhouse gases to consider in mitigating
climate change are methane and nitrous oxide, which have a higher global
warming potential per molecule than CO2 (GHG: CO2 = 1; CH4
= 25; N2O = 298), despite being present in relatively small amounts
in the atmosphere. Turfgrasses can serve as both sources and sinks for
greenhouse gases, including carbon dioxide (CO2), nitrous oxide (N2O),
and methane (CH4). Greenhouse gas emissions from turfgrasses are
largely caused by nitrogen fertilizer applications and mowing activities, and
this varies depending on turfgrass species, irrigation amount, rainfall, and
soil moisture levels. Necessary strategies should be implemented to reduce
greenhouse gas emissions in grass areas and their effects on climate change.
These; single-dose fertilizer application should be avoided, the optimum
fertilizer dose that provides acceptable grass quality values should be
applied, slow-release nitrogenous fertilizer sources should be used, limited
irrigation practices should be applied, nitrogen fertilization should be
avoided before heavy rains or during scorching summer months, grass species or
its varieties that need less fertilizer and maintenance should be used, and
maintenance equipment used in shaping, ventilation, sandblasting, and spraying
should be electrified. Well-managed turfgrasses have the potential to mitigate
climate change by sequestering carbon in the soil and reducing greenhouse gas
emission.
