There are three basic assumptions behind the proposed method: (1) all the Al measured during the first leach is derived from silicate minerals, (2) all the biogenic silica has been digested during the first leach, so the second leach addresses the Si:Al ratio of silicate minerals only, and (3) silicate minerals dissolve during the second digestion exactly .
Taking into account that the average error of the wet chemical extraction method followed by a colorimetric analysis is % of Si by dry weight, using NIRS for graminoids increases the average error with % of Si by dry weight, which is acceptable when working with plants accumulating Si (Si > %Si by dry weight; Raven, 2003).
