Furthermore, biogeochemical processes in acid soils might have favored the formation of CEC in the case of limestone. For example, the application of limestone to acid soils can increase soil pH, which can lead to the dissolution of Al and Fe oxides, releasing positively charged ions that can contribute to CEC [Citation 59].

Limestone has two origins: (1) biogenic precipitation from seawater, the primary agents being lime-secreting organisms and foraminifera; and (2) mechanical transport and deposition of preexisting limestones, forming clastic deposits. Travertine, tufa, caliche, chalk, sparite, and micrite are all varieties of limestone. Limestone has long …
