%X With simulation experiment in laboratory,the study was made on the relationship between the adsorption of boron onto lime soils and the physical and chemical properties of soils.Five types of soils were collected from the suburban areas of Beijing at differentheights above sea level,and were used to examine the factors that affect the adsorption of boron(B) onto soils.The results show that the adsorption of boron onto all the soils studied follows the Freundlich isothem adsorption equation and the amount of boron adsorbed increases with pH value of soil increasing,while the maximum reaches at pH10.0.At the same time,the boron adsorption was found to be positively correlative to the primary soil properties,such as contents of organic matter,CaCO3,and clay particles with a size of <0.002mm in soils.Among the soils,brown earth and paddy soil have a lower boron adsorption.
