“…In rice plants, Agarie et al (1998) found that the Si application reduced electrolyte leakage from cells, preventing the structural and functional impairment of the cell membrane of plants. According to Barbosa-Filho et al (2001), the presence of Si in the cell walls of plants can increase the lignin and hemicellulose content, increasing the rigidity of the cell.…”

“…A Si content of less than 9.8 and 13 mg dm -3 soluble in 0.5 mol L -1 acetic acid is considered responsive to the application of this element for rice yield (KORNDÖRFER et al, 1999;BARBOSA FILHO et al, 2001). Those levels are specially found in sandy and loamy sandy soils.…”

“…However, they focused on the evaluation of the acidity correction and Ca, Mg, and Si supply under field conditions (BARBOSA FILHO et al, 2001;KORNDÖRFER et al,2001;CARVALHO-PUPPATTO et al,2003) and pots (PEREIRA et al,2004;KORNDORFER et al, 1999;CAMARGO et al, 2007b) and only a few studies (RAMOS et al, 2008) have evaluated the benefits of Si supply for the rice crops on its uptake, yield and quality without the additional effects (increasing on pH and Ca and Mg content in soils) of silicate applied in tropical soils. The Ca and Mg levels in soil had to be used in the same quantities when different silicate rates were applied in soil, as already done in incubation studies of Si sources and rates (CAMARGO et al, 2007a;PEREIRA et al, , 2010.…”

“…According to Raij & Camargo (1973), the soluble Si content of most soils in the Brazilian Cerrado is low. In tropical soils, due to the favourable leaching conditions, Si is found basically in form of quartz (SiO 2 ), opal (SiO 2 .nH 2 O) and other minerals with no plant-available Si (Barbosa Filho et al, 2001). Additionally, Si containing easily leaching minerals is practically inexistent in strongly leached tropical soils (Pereira et al, 2003).…”
