The total amount of soluble salt in soil extract is linearly correlated with the conductivity in a certain concentration range.The conversion relationship between the total amount of soluble salt in soil and the conductivity is established to verify the total amount of soluble salt in soil measured by the conductivity method and the total salt content of soil measured by the gravimetric method.The results show that the conductivity method is accurate and effective in determining the total amount of soluble salt in soil.Compared with other analytical methods,the conductivity method has the advantages of simple process,high efficiency and accurate analysis results.
