“…Solubility of all the above Si forms is low and biogeochemically immobile. The major soluble forms of Si in the soil are poly- and monosilicic acids [ 26 ]; however, monosilicic acid occurs mostly in a feebly adsorbed condition [ 27 ] and has low capability to migrate inside the soil [ 28 ]. By increasing the monosilicic acid concentration in the soil solution, plants are able to absorb phosphates (P) directly.…”

Silicon (Si) is one of the most prevalent macroelements, performing an essential function in healing plants in response to environmental stresses. The purpose of using Si is to induce resistance to distinct stresses, diseases, and pathogens. Additionally, Si can improve the condition of soils, which contain toxic levels of heavy metals along with other chemical elements. Silicon minimizes toxicity of Fe, Al, and Mn, increases the availability of P, and enhances drought along with salt tolerance in plants through the formation of silicified tissues in plants. However, the concentration of Si depends on the plants genotype and organisms. Hence, the physiological mechanisms and metabolic activities of plants may be affected by Si application. Peptides as well as amino acids can effectively create polysilicic species through interactions with different species of silicate inside solution. The carboxylic acid and the alcohol groups of serine and asparagine tend not to engage in any significant role in polysilicates formation, but the hydroxyl group side chain can be involved in the formation of hydrogen bond with Si(OH)4. The mechanisms and trend of Si absorption are different between plant species. Furthermore, the transportation of Si requires an energy mechanism; thus, low temperatures and metabolic repressors inhibit Si transportation.

“…, 1995). Monosilicic acids migrate very slowly in the soil profile (Khalid and Silva, 1980) and their increased concentration in the soil solution results in transformation of plant‐unavailable phosphate into plant‐available phosphate (Matichenkov and Ammosova, 1996). Calculations from a sugarcane field showed that nearly 100 kg ha −1 of Si is removed from the soil at each harvest cycle (Savant et al.…”

The effects of five rates [0 (control), 1, 2, 4 and 6 Mg ha )1 ] of calcium silicate on the growth and water consumption by rhodes grass (Chloris gayana Kunth) and sudan grass (Sorghum sudanense Piper) under wet and dry soil water regimes (60 g and 30 g H 2 O kg )1 soil respectively) were evaluated in a pot experiment. The effect of the application of silicate on plant biomass was similar to that of the control. However, the shoot and root dry mass varied significantly (P < 0.001) according to the soil water regime and plant species. During the first cut, the shoot dry mass was 5.7 g per pot under the wet soil moisture regime, significantly exceeding that under the dry soil water regime proportionately by 0.68. For sudan grass, the shoot dry mass varied from 3.6 g per pot in the control to 4.3 g per pot in the treatment that received 6 Mg ha )1 of calcium silicate. Plant water demand decreased as the rate of calcium silicate application increased, suggesting that an application of calcium silicate could reduce drought stress and enhance water economy. For the soil under study, the reduction in plant water demand represents a water saving ranging from 0.076 to nearly 0.20.

“…Monosilicic and polysilicic acids are the two forms of Si that have high solubility in soil and belong to Si's liquid and adsorbed phase fragments (Matychenkov and Snyder, 1996b). Monosilicic acid is majorly present in a poorly adsorbed form and is less mobile in the soil environment (Matichenkov et al, 1997;Khalid and Silva, 1980). By raising the level of H 4 SiO 4 in soil, plant roots can absorb Si in them.…”

The abundance of silicon (Si) in the earth's crust is found as silicon dioxide (SiO2). But this abundance of Si is not a sign that the plants take up an adequate amount of Si. This review article incorporates research based on Si to understand the importance of Si in plants under various stress conditions and its role in sustainable agricultural production. Si's application is considered a better approach to providing stress tolerance to plants under stress conditions. The review describes the different phases of Si, its absorption, transport in plants, and its various mechanisms of action to tolerate specific stresses. The uptake and transport of Si through various Si transporters have also been reported. This review also discusses the various mechanisms of Si under biotic or abiotic stress in different plants. The application of Si improves soil quality and soil health and enhances the soil microbial population. In addition, the role of Si in the upregulation and down-regulation of proteins under stressful conditions has also been reported. The information can help to better understand the importance and mechanism of Si in plants and its application in agriculture.
