The Bluegrass region is characterized by underlying fossiliferous limestone, dolomite, and shale of the Ordovician geological age. Hills are generally rolling, and the soil is highly fertile for growing pasture. The Kentucky Bluegrass is bounded on the east by the Cumberland Plateau, with the Pottsville Escarpment forming the
If the soil pH is above 6, then use ammonium sulfate, which will acidify the soil. Turfgrass has been shown to be most resistant to summer patch when soil pH is between 5.5 and 6. Most balanced fertility programs for Kentucky Bluegrass lawns will consist of applying two to five lbs of nitrogen/1000 sq.ft. a year. [2]

The base temperature is that temperature below which plant growth is zero. GDs are calculated each day as maximum temperature plus the minimum temperature divided by 2, minus the base temperature.
