By using semi—micro—iodometrie method.the comparative studies on thb absorbent power of differant ions by different soil samples have been developed.It is noteworthy that the proposed technique is rapid and more reproucible.The theoretical equations are derived and the exoerimantal proceuresdare described.The maenitude of absorbent power of ion by soils is the intensity factorrespect to that of capacity factor.The reciprocal of coefficent of soil absoreent power of ion has been assumed to reprcsent the magnitude of soil absorbent power when the soil having been taken as reference has been fixedAccording fo this method.results of the absorbent power of different nutritious ions for cerfain paddy soils are presented.we get a linear relationshibatween ion—exchange adsorption of soil and nutritious ions.Tha absorbent power is not only a basic feature of soil except it’s chepical and physical property but also a fandamental character for ions.Fathermore,in the practice.the absorbent power of nutritious ionsasNH_4~+,K~+,Ca~(++)and Mg~(++)has been invstigated,The absbent cower of ions bycoarse sandy earth and clayloam,the relationship befween absorbent powemand cultural practice as well as a significant illnstration ete are also discusd in details.All these results have clearly displayed the significance of soil absorbent power in the respect of directing the plant nutrition and the adequatefertilization.
