In recent decades, anthropogenic soils have become so ubiquitous that for some authors they should be taken as the “golden spike” signaling the start of the Anthropocene. Despite their prominence, leading soil taxonomies have resisted calls to recognize them as a proper kind of soil. Such omission has importantly limited the ways in which soil practitioners can account and deal with the sociopolitical aspects embedded in soil formation. Approaching the issue from a sociomaterial perspective, this paper studies the effects of such omission on the work of soil scientists working in northern Chile. By contrasting their usage of the USDA/NRCS soil typology with the realities found in the field, the work of strategic unknowing that such typologies achieve becomes evident. To challenge such situation, the paper concludes exploring the notion of emergent taxonomies, classifications that are sensitive to local configurations of materials, living beings and power out which soils emerge.

近几十年来，人为土壤已变得无处不在，以至于对于某些作者而言，应将其视为标志着人类世开始的“金色尖峰”。尽管它们突出，但主要的土壤分类法却拒绝承认它们是适当土壤的呼吁。这种遗漏已严重限制了土壤从业人员能够解释和处理土壤形成中所包含的社会政治方面的方式。从社会材料的角度探讨这一问题，本文研究了这种遗漏对智利北部土壤科学家工作的影响。通过将他们对USDA / NRCS土壤类型学的使用与本领域中发现的现实情况进行对比，战略上知道这种类型学可以实现的工作变得显而易见。为了挑战这种情况，
