Siliceous soils are formed from rocks that have silica (SiO2) as a principal constituent. The parent material of siliceous soils may include quartz sands, chert, quartzite, quartz reefs, granite, rhyolite, ademellite, dellenite, quartz sandstone, quartz siltstone, siliceous tuff, among others.[1] These parent materials sometimes originate from silica-secreting organisms such as radiolarians, diatoms, or some types of sponges.[2]

Characteristics

Soils high in siliceous parent material typically have:[1]

  • lower cation-exchange capacity,
  • higher susceptibility to external sources of sodium,
  • lower buffering potential,
  • higher acidity, and
  • higher erodibility

Agriculture

Siliceous soils in vineyard soils have been linked to larger grapes with increased tannin content.[3][4]
