摘要：

The content of fixed ammonium was analyzed for 12 samples of upland soils, including Saline soils, Sols lessives, Meadow soils, Black-colored soils, and Dark-brown forest soils, collected from Jilin and Liaoning provinces, Northeast China, The content of fixed NH4+-N ranged from 0.11 to 0.27 g kg(-1) and no appreciable differences among the soil types were observed. Fixed NH4+-N accounted for 9 to 23% of total N in the Ap horizons.
