This document establishes a method for the determination of monosilicic acid concentrations in nonliquid fertilizer materials. Monosilicic acid is reported as silicon (Si).<\/p>\n

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 2 to 84 g\/kg, with a limit of detection (LOD) of 0,6 g\/kg Si, and a limit of quantification (LOQ) of 2 g\/kg correlating well with plant uptake.<\/p>\n

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.<\/p>\n
