Key functions of Si(OH4)

Enhances crop resistance towards drought stress (Hattori et al. 2005).
Mediate crop tolerance to salt stress (Yeo et al., 1999).
Plays a role in crop tolerance to metal toxicity such as aluminium in low pH soils (Lindsay, 1979).
Promotes the growth, yield and quality of most crops (Liang et al., 2015).
