Keep Off The Grass - Reduce Air Pollution
... "Emissions from grass are at their greatest in warm
weather and at around midday, when sunlight is most intense," says Mr Galbally. 'No gases are released at night.' "After we cut the grass in the chamber, gas release from clover rose by a factor of 80, and emissions from grass increased by 180 ...
