Studies on eluviation patterns of nitrogen and phosphorus in soil of golf course and the potential impact on water quality under simulative conditions

The dynamic variation of nitrogen and phosphorous movement in soil of golf course which is close to Tiegang Reservoir in Shenzhen and its impacts on water quality were studied under simulative conditions. The results indicated that the eluviated matters shown little impact on pH of water. The eluviating speed of organic matters in soil was very slow but it was fast for phosphorus and along the time the phosphorus was absorbed by soil. Nitrogen in soil could be rapidly eluviated than phosphorus. The total contents of nitrogen and nitrate increased gradually along with the time, which were three times more than that of water in the reservoir. Considering the low content of nitrogen and phosphorus in submerged soil, as well as the practical conditions and the natural factors in the time when the reservoir was submerged, the reservoir will come to a new dynamic balance after water was stored through water cycling. So it could be concluded that the eluviated nitrogen and phosphorous from soil of Shenzhen Tycoon Golf Course would not negatively affect the water quality of Shenzhen Tiegang Reservoir.
