Since the 1950s and early 1960s, 90% of Kentucky bluegrass seed in the United States has been produced on specialist farms in Idaho, Oregon and Washington. During the 1990s [citation needed] botanists began experimenting with hybrids of Poa pratensis and Texas bluegrass (P. arachnifera), with the goal of creating a drought and heat-resistant ...
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 Knobs Region or The Knobs is located in the US state of Kentucky. It is a narrow, arc-shaped region consisting of hundreds of isolated hills . The region wraps around the southern and eastern parts of the Bluegrass region in the north central to northeastern part of the state.
Barrens are open treeless areas on slopes, often with shallow soil. These are found sporadically in the Outer Bluegrass, Inner Nashville Basin, Shawnee Hills, and in parts of the Highland Rim. It is unclear whether these communities rely on fire for their openness, or are maintained by soil conditions alone. [ 4 ]

[1] Crops grown in the state include corn, soybeans, hay, wheat and tobacco. [2] Historically, hemp has been a cash crop in the state (see hemp in Kentucky).
However, the Kentucky Geological Survey estimated a cumulative total of 200,000 wells in 1992, with 23,000 oil wells and 11,000 gas wells producing in 1989. The Eastern Coal Field and Western Coal Field have been the mine sites of production, with little exploration in the Jackson Purchase and Bluegrass regions. [3]
