Abstract/Contents:Presents a study conducted to "determine the spatial variation of soil amino sugar nitrogen in managed turfgrass systems in order to determine sampling recommendations" using the Illinois Soil Nitrogen Test (ISNT). Details methods and materials used in the study, stating that "soil samples were collected from two fairways on each of two golf courses in Minnesota and analyzed for amino sugar nitrogen concentration...In order to determine the uniformity of amino sugar nitrogen distribution on the fairways, general geostatistical methods were used, and maps were generated using an interpolation technique called ordinary kriging. To test for a spatial correlation in amino sugar nitrogen levels between depths for a given fairway, the data were analyzed." Reports that "although the amino sugar nitrogen concentrations measured on the four sampled fairways varied, the spatial correlation present would allow traditional soil sampling techniques to be used to assess the soil amino sugar nitrogen concentration within an area such as a fairway...[The] data show that if new samples were taken from these fairways, and the samples were taken from locations separated by more than 328 feet (100 meters), then the samples would be considered independent."
