| Abstract: | This paper describes a method for determination of available zinc in soil using DTPA for dipping and using AAS for the result. Controllable factors which affect accuracy are analyzed. The results show that the procedure is convenient, rapid, accurate, and the contents of available zinc in soil arc not enough for providing on the whole in Heilongjiang Province. |
