How long decomposed buried human bodies affect soil elemental composition is so far not well-known. Using portable X-ray fluorescence spectrometry, we determined the elemental composition of sandy necrosols from a Corded Ware Culture (ca 2800–2500 BCE) graveyard, Chudeřín, Czech Republic. The elemental compositions of soils in the grave infills were studied and compared with arable and subsoil layers. After removal of the arable layer, infills of graves were identified by the black color in contrast with their reddish surroundings. The burials affected the content of elements even after more than 4500 years. Increased C contents compared with arable and subsoil layers were recorded only close to bones. The lowest P content was in grave infill, where soft tissues decomposed, because of P leaching. Therefore, increased P content in the infill of the prehistoric graves mentioned by previous authors is not a reliable indicator of soft tissue decomposition. In the acidic environment, P and Ca released from bones partly fixed in the grave infill ≤ 5 cm to bones. The high contents of P and Ca in bones and soils close to bones were a source of these elements for plants, indicated by a high density of fine roots. The highest contents of trace elements (Mn, Cu, As, and Pb) were in the arable layer because of recent disposition. The most reliable soft tissue decomposition indicator was an increased Zn content in the grave infill. The multi-elemental analyses of prehistoric necrosols were neglected so far and require further detailed research as the chemical signatures are well-preserved for millennia.

到目前为止，尚不清楚腐烂的埋葬人体会影响土壤元素组成多长时间。使用便携式X射线荧光光谱法，我们从捷克共和国Chudeřín的Corded Ware Culture（ca 2800–2500 BCE）墓地确定了沙质坏死溶胶的元素组成。研究了砾石填充物中土壤的元素组成，并将其与耕层和地下土壤层进行了比较。去除可耕层后，坟墓填充物通过黑色识别，与周围的环境略带红色。埋葬影响了元素的含量，甚至超过了4500年。与可耕层和下层土壤相比，增加的碳含量仅记录在骨头附近。磷含量最低的是在砾石中，由于磷的浸出，软组织分解了。因此，先前作者提到的史前墓葬中填充物中P含量的增加并不是软组织分解的可靠指标。在酸性环境中，从骨头释放的P和Ca部分固定在≤5 cm的坟墓中。骨骼和靠近骨骼的土壤中的高P和Ca含量是植物中这些元素的来源，其特征是高密度的细根。由于最近的处理，可耕层中的痕量元素（Mn，Cu，As和Pb）的含量最高。最可靠的软组织分解指标是坟墓中锌含量的增加。迄今为止，史前坏死病的多元素分析一直被忽略，因为其化学特征可以保存数千年，因此需要进一步的详细研究。
