Abstract/Contents:"Nitrogen and phosphorus are two important nutrients for turf growth. The amounts of nitrogen (N) and phosphorus (P) applied in excess of what the plants can use may move into streams by run-off and into ground water by leaching, thereby becoming an environmental hazard. Rooting media have varied retentive properties depending on their texture, organic matter content, and surface charge. This study examined nitrate and orthophosphate concentration in the leachate collected after natural storm events from 16 outdoor experimental golf green lysimeters amended with various organic amendments. The amendments included sphagnum peat moss (PM), treated steer manure (SM), biosolid/yard waste (BS) mix and steer + peat (SP) mix. Leachate collected from the first storm had the highest nitrate content of 313 mg l-1 among all the samples collected during the entire study period. Even after grow-in of bentgrass, leachate level occasionally exceeded 16 mg l-1, particularly for the leachate collected from the SM and SP treatments right after fertilizer application. The nitrate concentration of 16 mg lt-1 exceeded the allowable limit (10 mg l-1) set by the United States Environmental Protection Agency. In contrast to nitrate, the highest P content was obtained in the third storm after the lysimeters were established. P content in the leachate collected from both BS and PM treatments was low. For the BS treatment, the P was never higher than 2 mg l-1, and the highest P content of the PM treatment was only 0.4 mg l-1. Based on the results indicated when managing with organic amendments, such as steer manure or biosolid, special care needs to be taken in fertilizer application. The excess nitrate and orthophosphate may enter the environment."
