Abstract: New York City Parks began collecting soil data for Central Park in 1983 and continued for twenty years. The dataset produced from this study was analyzed to investigate the change of soil chemical properties to determine if management decreased spatial variability and if soil quality increases with management over the 20-year period. During the collection effort, 82 polygons (representing lawn areas) were sampled and analyzed for one or more of the following variables: pH, soil organic matter, nitrogen, phosphorous, and potassium, and electrical conductivity. Three time periods were analyzed for trends over time for these soil parameters. Preliminary results indicate that pH increases over time. We will examine the effects of management on soil properties both spatially and temporally.
