<p>Carbon sequestration in terrestrial ecosystems has emerged as a critical strategy to mitigate temperature related challenges, including climate change and global warming, primarily driven by carbon emissions. The quantifiable emission of toxic gases into the atmosphere causes climate change and global warming, important among them is carbon emissions. The viability of augmenting carbon sequestration in ornamental crops by means of silicon fertilization through altering rhizosphere—plant interactions associated with it can be considered as a practical mitigation measure for global climate change. Silicon fertilizer increases phytolith content by enhancing silica deposition in plant tissues, which promotes greater biomass production and organic carbon (phytOC). As plants with more phytoliths decompose, these silica bodies store carbon in the soil, paves the way for higher carbon stocks. Here experimental evidences demonstrating the potential of silicon fertilization to enhance stocking of carbon in ornamental crops is discussed. In addition to carbon sequestration, we have also explored the different impacts of silicon fertilization on ornamental plants. This work clarifies the processes by which silicon affects carbon sequestration through a series of carefully observed experiments, concentrating its impacts on plant physiology, root secretions, and microorganism in the rhizosphere. Insights into the relationships between the rhizosphere and silicon and its mobilization especially their mutual function in forming the microorganism that are associated with carbon cycle have been dealt with. Overall, this work highlights potential of silicon fertilization as an effective approach for improving ornamental crops ability to sequester carbondioxide and offers useful knowledge about the underlying mechanisms.</p> Graphical Abstract <p></p>
