John Mascaro's Photo Quiz
Answers from page 17
As you cAn see by the pile of flooring in the photo, there has
been a concert on this field or in this case an ongoing construction
project as the blue and grey area is in the shape of a ladder. The
obvious guess would be that a summer concert caused heat burn
stress on the Ryegrass turf; however this actually happened in early
April in Denver. There was an ongoing construction project installing
new, larger video boards with two cranes. The construction company left the small aluminum ladder on the grass just outside of
where the field covers reach on what would be a record cold night
with a single digit low of 6 degrees F. The ladder imprint is the result
of direct low temperature injury to the young ryegrass turf. The extra
cold transferred by the ladder from the air to the turf put this grass
over the cold temperature injury threshold. Luckily, the marks were
turf canopy damage only and the area was allowed to grow and the
damage was simply mowed off. n
