Abstract: Soil column leaching experiment showed that after zeolite application,the content of nitrogen and potassium in leachate was reduced significantly,but no significant effect was detected for phosphate.This application had a positive effect on soil available nitrogen,phosphorus and potassium.It increased the content of soil AL-P and Fe-P,but did not increase the NO3--N content in leachate.
