Outsiders often oversimplify Amazon soil use by assuming that abundantly available natural soils are poorly suited to agriculture and that sporadic anthropogenic soils are agriculturally productive. Local perceptions about the potentials and limitations of soils probably differ, but information on these perceptions is scarce. We therefore examined how four indigenous communities in the Middle Caquetá River region in the Colombian Amazon classify and use natural and anthropogenic soils. The study was framed in ethnopedology: local classifications, preferences, rankings, and soil uses were recorded through interviews and field observations. These communities recognized nine soils varying in suitability for agriculture. They identified anthropogenic soils as most suitable for agriculture, but only one group used them predominantly for their swiddens. As these communities did not perceive soil nutrient status as limiting, they did not base crop-site selection on soil fertility or on the interplay between soil quality and performance of manioc genetic resources.
外界往往将亚马逊地区的土壤利用情况过度简化，认为大量存在的天然土壤不太适合农业，而零星分布的人为土壤则具有农业生产力。当地人对土壤潜力和局限性的认知可能存在差异，但关于这些认知的信息却很匮乏。因此，我们研究了哥伦比亚亚马逊地区卡克塔河中游地区的四个土著社区如何对天然土壤和人为土壤进行分类以及利用。该研究以民族土壤学为框架：通过访谈和实地观察记录当地的分类、偏好、排名以及土壤利用情况。这些社区识别出九种对农业适宜性各异的土壤。他们认为人为土壤最适合农业，但只有一个群体主要将其用于刀耕火种的农田。由于这些社区并不认为土壤养分状况具有限制作用，所以他们在选择作物种植地点时，并非基于土壤肥力，也不是基于土壤质量与木薯遗传资源表现之间的相互作用。
