Dynamics of carbon loss from an Arenosol by a forest to vineyard land use change on a centennial scale
<p>Few studies have focused on Arenosols with regard to soil carbon dynamics despite the fact that they represent 7 % of the world's soils and are present in key areas where food security is a major issue (e.g., in Sahelian regions). As for other soil types, land use changes (from forest...

| description | <p>Few studies have focused on Arenosols with regard to soil carbon dynamics despite the fact that they represent 7 % of the world's soils and are present in key areas where food security is a major issue (e.g., in Sahelian regions). As for other soil types, land use changes (from forest or grassland to cropland) lead to a loss of substantial soil organic carbon (SOC) stocks and have a lasting impact on the SOC turnover. Here we quantified long-term variations in carbon stocks and their dynamics in a 80 <span class="inline-formula">cm</span> deep Mediterranean Arenosol that had undergone a forest-to-vineyard land use change over a 100 years ago. Paired sites of adjacent plots combined with carbon and nitrogen quantification and natural radiocarbon (<span class="inline-formula"><sup>14</sup>C</span>) abundance analyses revealed a <span class="inline-formula">C</span> stock of 53 <span class="inline-formula">t ha<sup>−1</sup></span> in the 0–30 <span class="inline-formula">cm</span> forest soil horizon, which was reduced to 3 <span class="inline-formula">t ha<sup>−1</sup></span> after long-term grape cultivation. Total organic carbon in the vineyard was dramatically low, with around 1 <span class="inline-formula">g C kg<sup>−1</sup></span>, and there was no vertical gradient as a function of depth. <span class="inline-formula"><sup>14</sup>C</span> showed that deep plowing (50 <span class="inline-formula">cm</span>) in the vineyard plot redistributed the remaining carbon both vertically and horizontally. This remaining carbon was old (compared to that of the forest), which had a <span class="inline-formula">C:N</span> ratio characteristic of microbial organic matter and was probably stabilized within organomineral associations. Despite the drastic degradation of the organic matter (OM) pool in this Arenosol, this soil would have a high carbon storage potential if agricultural practices, such as grassing or organic amendment applications, were to be implemented within the framework of the 4 per 1000 initiative.</p> |
