| Abstract: | Available phosphorus in calcareous soil was determined by ICP-MS,and the determination limit was 0.090μg/g.The analytical results of the available reference standard matter in national soil and industry reference standard matter were in agreement with standard values.The relative standard deviation（n=11） of four reference samples（GBW 7413,GBW 7414,ASA-8,ASA-9） were less than 5%. |
