  "definition": "The petrocalcic horizon is an illuvial horizon in which secondary calcium carbonate or other carbonates have accumulated to the extent that the horizon is cemented or indurated. In some soils forming in parent materials that are rich in carbonates or that receive regular additions of carbonates in dust, the calcic horizon tends in time to become plugged with carbonates and cemented into a massive, continuous horizon.",
