SOBECK & EBELING: MASS SPECTROMETRIC ANALYSIS FOR P
HOSPHATE IN SOIL EXTRACTS
4
Inductively coupled plasma (ICP) optical emission s
pectroscopy.
“Total elemental analysis” by ICP optical
emission spectroscopy on the AmOx-extracted BIO Inc
soil samples was performed by the University of Wi
sconsin
Soil and Plant Analysis Lab (Madison, WI). The res
ults from the P emission at 213.62 nm were used.
