Impacts of Nitrogen Deposition on Soil Available Phosphorus in Schima superba and Pinus massoniana Mixed Forest
An experiment was conducted to study the impacts of nitrogen deposition on soil available phosphorus in a Schima superba and Pinus massoniana mixed forest in Fuzhou National Forest Park of Fuzhou City by field test and laboratory measurement. Results showed that, for the same nitrogen deposition treatment, the content of available phosphorus decreased with the increase of soil depth; while for different nitrogen deposition treatments, the content of available phosphorus in the same soil layer was first restrained by the nitrogen deposition and then turned to increase. The treatment of high contents of nitrogen (150 kg · hm -2 · a-1) simulated nine months was proved to be helpful to the absorption of soil available phosphorus.
