John Mascaro’s Photo Quiz Answers from page 17
THESE BROWN SPOTS started showing up on this athletic field about a week after these fields were fertilized and they received quite a bit of rain. The region was also experiencing nice, warm 90 degree temperatures that caused a very good flush of turfgrass growth. This Bluegrass sports complex is usually mowed at a height of about 2 inches but the combination of rainfall, fertilizer and warm weather be- tween Friday and the following Monday produced a turf height that was close to 3 inches. When the fields were mowed, they produced an excessive amount of grass clippings. The crew decided that using a turf sweeper would quickly and cleanly remove the exces- sive turfgrass clippings. As the sports turf technician drove the sweeper, they would shut off the sweeping brush before turning around and then turn it on while sitting still for a moment. Since the air temperature was close to 90 degrees, this action of engag- ing the sweeper caused these brown areas. The burn was just su- perficial leaf injury and was mowed off with the next mowing causing no real harm to the fields.
