Silicon (Si) is the second richest element in the soil and surface of earth crust with a variety
of positive roles in soils and plants. Different soil factors influence the Si bioavailability in soil …

Silicon (Si) speciation and availability in soils is highly important for ecosystem functioning,
because Si is a beneficial element for plant growth. Si chemistry is highly complex compared …

There is increased interest in the terrestrial silicon cycle in the last decades as its different
compounds and species have large implications for ecosystem performance in terms of soil …

The element silicon (Si) is required for the growth of silicified organisms in marine
environments, such as diatoms. These organisms consume vast amounts of Si together with …

Humankind will need to remove hundreds of gigatons of carbon dioxide (CO2) from the
atmosphere by the end of the 21st century to keep global warming below 2° C within the …

Over the past few decades, we have realized that the silica cycle is strongly intertwined with
other major biogeochemical cycles, like those of carbon and nitrogen, and as such is …

Chemical weathering is an integral part of both the rock and carbon cycles and is being
affected by changes in land use, particularly as a result of agricultural practices such as …

The silicon isotope composition of biogenic silica (δ 30 Si BSi) in the ocean is a function of
the δ 30 Si of the available dissolved Si (DSi; H 2 SiO 4), the degree of utilisation of the …

Enhanced weathering (EW) is one of the most promising negative emissions technologies
urgently needed to limit global warming to at least below 2° C, a goal recently reaffirmed at …

Plants' ability to take up silicon from the soil, accumulate it within their tissues and then
reincorporate it into the soil through litter creates an intricate network of feedback …
