Abstract/Contents:Discusses a method for measuring and evaluating the soil compaction and surface hardness of sports fields, stating that "the American Society for Testing and Materials (ASTM) has developed a set of procedures utilizing a device called the Clegg Impact Soil tester (CIST) to assess the surface hardness of North American football fields." Details physical characteristics and operational procedures of the CIST, noting that "the CIST consists of a cylindrical impact missile enclosed in a tube that creates minimal friction. The missile is dropped at a prescribed height of 2.0-ft [feet] on the surface to be tested." Recommends six specific points on football fields where drop tests potentially should be conducted. Identifies parameters to be reported at the time of testing, advising that "in a natural turfgrass system, the surface temperature of the field should be measured at a depth of 0.5-inch. Additionally, a visual assessment of turfgrass cover (e.g. [for example] 25% [percent], 90%, etc. [et cetera]) and soil moisture (dry, damp, wet, saturated, etc.) should be made [and] recorded at each test point."
