This document establishes a method for the determination of monosilicic acid concentrations in nonliquid fertilizer materials. Monosilicic acid is reported as % Si.
This extraction method is applicable to the detection of monosilicic acid in nonliquid fertilizer products, blended products, and beneficial substances at silicon (Si) concentrations of 0,2 to 8,4 %, with a Limit of Detection (LOD) of 0.06 % Si, and a Limit of Quantification (LOQ) of 0,20 % correlating well with plant uptake.
This method is not applicable to liquid silicon fertilizer sources due to an expected low bias of Si recovery and low correlation with plant uptake.
