Abstract:

In this paper, 20 soil samples were collected from plow layers and plow pans of fairways, tee grounds, and putting greens on a golf course, respectively. In addition, the vertical and horizontal distribution of the contents of Cr, Ni, As, Cd, Hg, Pb, and Cu were analyzed at different soil depths in three types of turf areas. Heavy metal contents in other places basically satisfied the trend of plow pan>plough layer. Heavy metal contents in other places basically followed the trend of plow pan>plough layer, except for As and Hg in fairway soil and Cd in putting green soil. A comparison was conducted on the soil heavy metal contents in the plow layers and plow pans of fairway, tee ground, and putting green, and no significant difference was observed. However, in terms of the average contents of heavy metals in two depths, the average contents of Cd, Pb, and Cu showed an order of fairway > tee ground > putting green; the average contents of Hg and Ni showed an order of tee ground > fairway > putting green. For the average contents of Cr and As, the order was putting green > fairway > tee ground and fairway > putting green > tee ground, respectively. The contents of As and Pb in the turf soil on the golf course did not exceed the national standard limit, but were higher than the background values. The Cd and Hg contents and the Cr contents in the fairway plow pan and plow layer of the putting green exceeded both the national standard limit and the background values, and therefore presented a serious enrichment problem. The vertical distribution of soil heavy metals in the turf soil on the golf course was mainly influenced by the quantity of chemical fertilizers applied and rainfall, whereas the soil heavy metal contents of different turfs on the golf course were determined mainly by the quality of fertilizers applied.
