Abstract: Afield experimentwas setup to study the effects of increasedNdeposition on the chemical properties of the soils under Chinese fir(Cunninghamia lanceolata) plantations growing in mid-western Fujian, China.Treatmentswere designed as 0 kghm- 2a- 1N, 60 kghm- 2a- 1N, 120 kghm- 2a- 1 N, and 240 kghm- 2 a- 1N, with three replicates in each treatment. Ureawas used as the source ofN and its solutionswere sprayed on the forestground eachmonth fortwoyears. Results showed thatpH, available P andK, and exchange-eable Ca2+ and Mg2+ in the soils decreased, but NH4+-N and NO3--N increased with increasing N deposition. For all the treatments, soil available nutrient levels decreased(P 0.01)with the soil depth, but soil pHincreased(P0.05)with increasing depth.[Ch, 6 fig. 3 tab. 30 ref.]
