贝达德-豪恩，A. 2011.加拿大潜育土：起源、分布和分类。可以的.《土壤科学杂志》91：763-779。本文综述了潜育土的成土作用，包括它们如何影响土地利用和气候变化。在加拿大土壤分类系统中，潜育土目包括所有具有氧化还原过程或潜育作用的主要物理证据的形态特征的土壤。潜育特征包括由于周期性或永久性饱和条件而产生的暗淡颜色的土壤基质和/或明亮颜色的斑点。在饱和条件下，氧气迅速耗尽，微生物在有机物的分解中使用替代的末端电子受体（如铁，Fe 3+）。潜育土在加拿大各地都有发现，无论是在低洼的景观位置，与排水良好的土壤秩序（例如，草原坑洼地区），或作为主要土壤类型，地形和/或缓慢的土壤类型。
Bedard-Haughn, A. 2011. Gleysolic soils of Canada: Genesis, distribution, and classification. Can. J. Soil Sci. 91: 763–779. This review examines the pedogenesis of Gleysolic soils, including how they affect and are affected by land use and climate change. In the Canadian System of Soil Classification, the Gleysolic Order includes all those soils with morphologic features that provide dominant physical evidence of oxidation-reduction processes or gleying. Gley features include dull coloured soil matrices and/or brightly coloured mottles, which arise due to periodic or permanently saturated conditions. Under saturated conditions, oxygen is rapidly depleted and alternative terminal electron acceptors (such as iron, Fe3+) are used by microorganisms in the decomposition of organic matter. Gleysolic soils are found throughout Canada, either in low-lying landscape positions in association with better-drained soil orders (e.g., Prairie Pothole region), or as the dominant soil type where topography and/or a slowl...
