Product Manual

Take the air temperature about three feet above the turf and take a note of this.
Next take three temperature readings in the turf.
FIRST: Take a reading at the one inch level. (Usually in the thatch.)
SECOND: Take your next reading at the two inch level.
THIRD: The final reading should be taken at the three inch level.
Take temperatures at midday when solar radiation is most intense. Learn to
correlate all three readings. If air and soil temperature is high syringing should
be done immediately.
Generally speaking, bentgrass grows best at temperatures between 75 and 80
degrees Fahrenheit. Bermudagrass grows best at 95 to 100 degrees Fahrenheit.
Sudden higher temperatures should be a warning that thatch may be
decomposing rapidly or that dry spots are developing. Corrective actions should
be taken immediately.
If problems persist, the problems may be basic. These include compaction,
layers, thatch, drainage or nutrition problems. Unless the basic problems are
isolated and corrected, constant vigilance is required to keep the grass from
dying.
