Tibetan croplands possess their unique soil characteristics due to the special geographical location, climate type, and geological records of Tibet and the cultivation practices of the local farmers. Soil samples from farmlands in Linzhi, Lhasa, Ricaze and Shannan, the major agricultural areas of Tibet, were collected and analyzed in the period from 2002 to 2004. The results showed that the soils varied from weakly acidity (pH 6.5) to weakly alkalinity (pH 9.0), and from 5 to 50 g/kg in organic matter contents, were inadequate in soil N (total N 0.2~2 g/kg, and readily available N 20~80 mg/kg), deficient in P (total P 0.22~1.42 g/kg, and readily available P 1~133 mg/kg), but rich in K (total K 1.9~12.2 g/kg, and readily available K 80~1290 mg/kg) and microelements (Cu 10~443 mg/kg, Zn 47~266 mg/kg, Fe 1880~7550 mg/kg, Mo 0.2~6.6 mg/kg, Mg 196~736 mg/kg, B 0.5~138 mg/kg).
