Comparison of Colorimetric and ICP Techniques for Phosphorus Determination in Mehlich-1 and -3 Soil Extracts
FAES Project Number: SWS-03865
Project Duration: Short
Goals and Objectives
Comparison of colorimetric and ICP Mehlich-1 and -3 extractable
phosphorus concentrations indicate that the P concentraions tend
to be overestimated by the ICP techniques. A regional study (southeast)
has been initiated through the SERA-IEG-6 committee to investigate
the reasons for accurate P determination and identify the appropriate
techniques.
