Abstract
Off-leash dog parks are very popular locations that allow pets to freely exercise and eliminate wastes in a controlled environment. Although dog park rules require that solid waste be removed by the pet’s owner, urine-borne constituents in dog-park soils have received little attention. This study focused on the soils within two small-dog, off-leash dog parks in Fargo, North Dakota (USA) with the objective to better understand the concentration and distribution of extractable NH4-N, NO3-N, PO4, soluble salts, and pH values in surface soils (0–10 cm) within these two dog parks. Concentrations of soil variables varied widely within each park and were distributed as both gradient and ‘hot-spots.’ The geospatial model types for each soil parameter were more dependent on park than on the constituents themselves. Flow accumulation was correlated with both nitrate-N and P but due to the lack of topography at these parks the flow accumulation was not helpful in describing most of the soil constituents. The results from this project indicate that location of parks, daily/annual use of parks, flow accumulation, and location of park entries may all influence the concentration and distribution of urine-borne constituents.
