N2  - A study was conducted for comparative evaluation of atomic absorption
spectrophotometry (AAS) and inductively coupled plasma?optical emission spectroscopy
(ICP-OES) for determining extractable zinc (Zn), copper (Cu), manganese
(Mn), and iron (Fe) in sixty diverse soil samples having a wide range in pH and organic
carbon (C). The results were significantly affected by the method of analysis and soil
type but generally did not follow a definite trend. Results for extractable Fe in Alfisol
samples were significantly greater when using ICP-OES than AAS; and the results for
Zn, Cu, and Mn were not significantly different for the two methods. For Vertisol samples,
the results for extractable Cu were significantly greater by ICP-OES than by AAS,
whereas extractable Fe and Zn were significantly greater by AAS than by ICP-OES,
and the results for Mn were not significantly different for the two methods. The results
are discussed relative to soil type and differences in soil organic carbon and pH of the
samples used in the study.
