Abstract
A review of methods for soil extraction used in the United States is given starting from the early 1940s to today. With the use of multielement analyzers, primarily the inductively coupled plasma emission spectrometer (ICP‐AES), extraction procedures being adopted today are those with multielement capabilities, such as Mehlich No. 3 and ammonium bicarbonate‐DTPA (AB‐DTPA).Keywords
