“…Traditionally, there has been discussion about the most relevant morphological features and carbonate accumulation criteria in soils. Globally speaking, extensive terminology has developed over several decades to describe pedogenic carbonate accumulation (i.e., Barta, 2011; Birkeland, 1999; Bullock et al, 1985; Durand et al, 2010; Gile et al, 1966; Soil Survey Staff, 1975; Stoops, 2003) or, more recently, Durand et al (2018) and Golubtsov et al (2021). Nevertheless, the literature on secondary carbonates is often ambiguous.…”

Many vineyard soils in semiarid Mediterranean environments develop from carbonated materials and often show very diverse forms of pedogenic Ca‐carbonate accumulations. Based on 275 vineyard soil profiles in the Castilla La Mancha (CLM) territory (Spain), this paper presents an in‐depth comprehensive study of a large number of morphological expressions of these carbonate distributions, while exploring various pedogenesis formation hypotheses. The interactions among the calcareous nature of parent material, surface topography and climate are the factors that most affected their morphology and pedogenesis. The occurrence and distribution of carbonate features in CLM vineyard soils can be more complex than other areas. Many accumulations are relatively ancient, which is the case of petrocalcic horizons, and in‐keeping with conservative means, which reveals the occurrence of successive carbonate accumulation cycles. More recently dissolved and precipitated seasonally pedogenic carbonates (sometimes as coatings) have appeared, which are nothing more than a simple recent redistribution of carbonates. A structural imprint is observed: pedogenic carbonates appeared much more abundantly on the lowermost horizons, which can be related to the repeated redistribution phases that occurred in different pedogenesis stages. The data provided herein help to understand the nature of viticultural calcareous soils in semiarid Mediterranean regions.

“…Investigating inter-seasonal variability of PC formation and seasonality of rainfall, Gallagher et al [40] determined hydrological parameters (rainfall, evaporation, and soil water content) as the primary factors, rather than the mean annual temperature that was believed to previously be the main control. However, the vital role of temperature in PC dynamics in forest-steppe soils (alongside the mentioned hydrological parameters and biological activities in the growing season) has also been documented [41].…”

As a principal part of the atmosphere–lithosphere interface, soil plays a key role in regulating the atmospheric CO2 concentration and global climate. Comprising two major pools (carbonate in soils and bicarbonate in groundwater), soil inorganic carbon (SIC) is deemed as the primary carbon (C) sink and source in areas with low mean annual rainfall. SIC may originate from soil parent material or from the formation of secondary carbonate when divalent cations from an extraneous source are supplied. The latter may result in pedogenic carbonate (PC) formation, increasing soil C content and sequestering atmospheric carbon. Since the sequestration of atmospheric CO2 through formation of pedogenic carbonate is gaining popularity as a method to support climate change mitigation efforts and to claim carbon credits, the mechanisms influencing the formation and migration of pedogenic carbonate need to be well understood. The present review provides an overview of the available literature on potential natural and anthropogenic factors influencing the pedogenic carbonate pool in soils. Firstly, the overall mechanisms of pedogenic carbonate formation, as well as the control factors, are described. Secondly, the impact of various land-use changes on pedogenic carbon pool modification is discussed. Then, the potential of stabilizing atmospheric CO2 through PC formation and the challenges and techniques of tracking the formation of PC through engineered pathways in soils are explored. Finally, isotopic signature as a technique for distinguishing neo-formed carbonate in soil is scrutinized.

“…Therefore, SIC losses have irreversible and unpredictable implications for soil health, food security and climate amelioration ( Wang et al, 2021 , Raza et al, 2021 ). SIC stocks may increase solely in the presence of Ca 2+ by CO 2 fixation leading to pedogenic carbonate formation, which can be more stable than newly sequestered SOC ( Golubtsov et al, 2021 , An et al, 2019 , Dang et al, 2022 , Liu et al, 2023 ). Oxalotrophic bacteria can also increase SIC stocks by producing carbonates during oxidation of ubiquitous oxalate through a process called oxalate-carbonate pathway ( Syed et al, 2020 , Rowley et al, 2017 ).…”
