Wind eroded sediment is sorted by height by both size and density. Less information is available about the elemental composition and enrichment ratios of these sediments. Because of that, the concentration of elements in wind-blown sediments of a sandy- and a sandy loam soil of the semiarid Argentinean Pampas were analyzed. With this purpose, a wind tunnel study was performed for obtaining the saltating sediments transported at different heights, and a sorption-based laboratory procedure was used to separate the particulate matter. Results showed that Ca and Mg were transported at low- and C and N at high heights. These tendencies were attributed to the accumulation of Ca and Mg in coarse minerals, probably apatite and Ca-feldspars, which are heavily transported by the wind, and to the accumulation of C and N in low-dense organic substances, fresh debris and polysaccharides, easily transported by the wind. Total S did not show a preference to be transported at any height, possibly due to its accumulation in organic and mineral substances. The transport of C and N was more segregated in the sandy- than in the sandy loam soil, in agreement with the better aggregation of the latter, in which some of its organic substances (carboxylic acids, amides and aromatics), form coarse and heavily transportable aggregates. From the obtained results it can be deduced that C and N would be widespread larger than Ca and Mg. Assembling of data obtained to mass fluxes, becomes relevant for modeling the biogeochemical cycles.

风蚀沉积物按高度，大小和密度分类。关于这些沉积物的元素组成和富集率的信息很少。因此，分析了半干旱阿根廷南美大草原的沙质和沙质壤土的风吹沉积物中的元素浓度。为此，进行了风洞研究以获取在不同高度下运输的盐分沉积物，并使用了基于吸附的实验室程序来分离颗粒物。结果表明，Ca和Mg在低高度运输，C和N在高高度运输。这些趋势归因于Ca和Mg在风中大量运输的粗矿物（可能是磷灰石和Ca长石）中的积累，以及C和N在低密度有机物质中的积累，新鲜的碎片和多糖，容易被风吹走。总硫并未表现出优先选择在任何高度运输的可能，这可能是由于其在有机和矿物物质中的积累。碳和氮在沙质土壤中的迁移比在沙质壤土中更分离，这与后者更好的聚集相一致，后者的某些有机物质（羧酸，酰胺和芳烃）形成粗大且重质。可运输的骨料。从获得的结果可以推断出，C和N比Ca和Mg大得多。将获得的质量通量数据组合起来，对于建模生物地球化学循环变得至关重要。可能是由于其在有机和矿物质中的积累。碳和氮在沙质土壤中的迁移比在沙质壤土中更分离，这与后者更好的聚集相一致，后者的某些有机物质（羧酸，酰胺和芳烃）形成粗大且重质。可运输的骨料。从获得的结果可以推断出，C和N比Ca和Mg大得多。将获得的质量通量数据组合起来，对于建模生物地球化学循环变得至关重要。可能是由于其在有机和矿物质中的积累。碳和氮在沙质土壤中的迁移比在沙质壤土中更分离，这与后者更好的聚集相一致，后者的某些有机物质（羧酸，酰胺和芳烃）形成粗大且重质。可运输的骨料。从获得的结果可以推断出，C和N比Ca和Mg大得多。将获得的质量通量数据组合起来，对于建模生物地球化学循环变得至关重要。从获得的结果可以推断出，C和N比Ca和Mg大得多。将获得的质量通量数据组合起来，对于建模生物地球化学循环变得至关重要。从获得的结果可以推断出，C和N比Ca和Mg大得多。将获得的质量通量数据组合起来，对于建模生物地球化学循环变得至关重要。
