  KCl-EDTA-, CaCl₂-DTPA-, CaCl₂-DTPA-TEA extraction
  methods were compared to determine the plant available Cu
  amounts in the soil samples. In the soil extracts, the amounts of
  copper were measurable. In the buffered CaCl₂-DTPA-TEA
  extracts, data showed the lowest values.
  On the applied soils, a correlation was observed between
  plant removal and soil Cu using extractants mentioned above. The
  closest correlation appeared in the case of sandy soils.
  From the results of statistical analysis, it appears that soil
  properties may play role in the efficiency of the extraction using
  either CaCl₂-DTPA or KCl-EDTA solutions.
  To establish more reliable relations, further studies with
  different types of soils are needed.
