Abstract: Experiments conducted on 10 sample soils show no marked differences between the E and L values of surface soil. The L value is an individual point of the kinetic equation and isotopically exchangeable phosphate is the source of phosphate for bentgrass. The extensive use of P carriers in the experiment may have caused certain discrepancies in the L and E values of some samples.
