Abstract

With the aim of contributing to the knowledge of soil organic carbon stocks in dry areas, this work is based on a quantification of SOC stocks in gypsum-bearing soils whose vertical and spatial heterogeneity greatly limits inferring the total SOC stocks solely from soil surface information. Public databases of soil profiles were key to this quantification, through which it was estimated which amounts of organic carbon can potentially be excluded from calculations associated with soil C cycle models in the absence of information regarding deep soil horizons. These databases include two key factors in the quantification of SOC stocks, which are often excluded: the volume of coarse fragments and the thickness of all sampled soil horizons where SOC concentration was determined. The observed average value of SOC stocks in the studied subsurface horizons reaches 73% of the whole soil. Climate, relief, and land use influence the quantity and heterogeneity of SOC stocks in these soils. Information based on the mere surface of the soil is not relevant to quantify the total SOC; however, the calculation of stocks through soil pits of medium depth (30 cm) has proven to be potentially useful as a complementary approach to these stocks.

含石膏土壤碳储量评价:地下土层的作用
为了对干旱地区的土壤有机碳储量有所贡献,本研究基于含石膏土壤有机碳储量的量化,其垂直和空间异质性极大地限制了仅从土壤表面信息推断总有机碳储量。土壤剖面的公共数据库是这一量化的关键,通过这些数据库,可以估计在缺乏深层土壤层位信息的情况下,哪些有机碳量可能被排除在与土壤C循环模型相关的计算之外。这些数据库包括两个通常被排除在外的量化有机碳储量的关键因素:粗碎片的体积和测定有机碳浓度的所有采样土壤层的厚度。研究区地下层土壤有机碳储量观测平均值达到全土层的73%。气候、地形和土地利用影响这些土壤有机碳储量的数量和异质性。单纯基于土壤表面的信息与土壤有机碳总量的量化不相关;但是,通过中等深度(30厘米)的土坑计算储量已被证明是对这些储量的一种补充方法。
