亚马逊暗土(ADEs)是在非肥沃土壤占主导地位的地区的高度肥沃的土壤。然而,不同地区间营养物质有效性的差异以及ADEs对现代农业利用的适应能力仍然知之甚少,特别是在微量营养素含量方面。因此,本研究综合了ADE对不同土壤深度可提取微量元素(Cu、Ni、Fe、Mn、Zn、B)含量影响的现有信息,详细评价了土壤深度和土地利用类型对亚马逊不同地区9个ADEs及邻近地区(ADJ)土壤可提取Cu、Ni、Fe、Mn和Zn的影响。在Iranduba、Belterra和Porto Velho选择的土地利用系统为次生老森林(OF)或幼林(YF)和农业系统(AS)。只有8项研究比较了21个地点与ADEs和ADJ土壤的可提取微量元素(Mehlich-1)含量,但只有4项研究的深度大于30 cm, B和Ni仅在1项研究中进行了评估。从文献资料和本研究中均发现ADEs中Mn和Zn含量较高,而Fe含量较低,特别是在前30cm深度。ADEs中可提取的Ni和Cu的增加根据所考虑的地点和土地利用而变化。微量元素含量随深度的增加而降低,但因元素、立地、土壤类型和土地利用的不同而不同。除了贝尔特拉的铁和韦柳港的锰含量下降外,现代农业遗址的可提取微量营养素含量几乎没有差异。考虑到ADEs中某些微量和宏量营养素的含量较高,需要进一步研究在这些土壤上生长的植物的土壤管理和养分平衡。
Amazonian Dark Earths (ADEs) are highly fertile soils in areas with predominance of unfertile soils. However, the variation in nutrient availability between regions and the resilience of ADEs to modern agricultural use is still little known, particularly regarding micronutrient contents. Hence, the present study synthesized current information of ADE impacts on extractable micronutrient (Cu, Ni, Fe, Mn, Zn, B) contents at different soil depths and assessed in detail the role of both soil depth and land-use type on extractable Cu, Ni, Fe, Mn and Zn in nine ADEs and adjacent (ADJ) soils from different Amazonian regions. The land-use systems chosen were secondary old (OF) or young (YF) forests, and agricultural systems (AS) in Iranduba, Belterra and Porto Velho. Only eight studies compared extractable (Mehlich-1) micronutrient contents at 21 sites with ADEs and ADJ soils, but only four studies included depths greater than 30 cm, and B and Ni were evaluated in only one study. Higher Mn and Zn, but lower Fe contents were found in ADEs both from literature data and in the present study, especially in the first 30 cm depth. Increases in extractable Ni and Cu in ADEs varied according to the site and the land use considered. Micronutrient contents tended to decrease with depth, but varied depending on the element, site, soil type and land use. Sites with modern agriculture showed few differences in extractable micronutrient contents, except for a decrease in Fe in Belterra and Mn in Porto Velho. Considering the high amounts of some micro- and macronutrients in ADEs further work is warranted concerning soil management and nutrient balance in plants grown on these soils.
