Abstract

Abstract Mottling and gleying remain important characteristics for the classification of soils in Canada. The development of criteria for the morphological description of these redoximorphic soil features, for soil horizon nomenclature, for the taxonomy of gleysolic and gleyed soils, as well as for soil drainage classification, began in the mid-1940s and continued for the next four decades. Despite advancements elsewhere, notably with Soil Taxonomy and the World Reference Base, there have been minimal refinements made in Canada, during the past quarter century. Various issues are identified, including the need for more succinct and clearer definitions, a revision of standards for the field characterization of redoximorphic features, as well as more consistency in the application of concepts across existing taxa and systems. A taxonomic framework to more effectively reflect redoximorphic features, such as a new “Redoximorphic Phase” is also discussed. Ultimately, it is recommended that a special committee to be established to conduct a thorough study and present recommendations.

加拿大土壤表征和分类中斑点和潜育的合理化
斑点和潜育仍然是加拿大土壤分类的重要特征。从20世纪40年代中期开始,制定了对这些重样土壤特征的形态描述、土壤层命名、潜育土和潜育土的分类以及土壤排水分类的标准,并持续了40年。尽管在其他地方取得了进步,特别是在土壤分类学和世界参考基地方面,但在过去的四分之一个世纪里,加拿大的改进程度很低。确定了各种问题,包括需要更简洁、更清晰的定义,修订重做形态特征的现场表征标准,以及在现有分类群和系统中应用概念的一致性。还讨论了一个更有效地反映再氧化态特征的分类框架,如一个新的“再氧化态阶段”。最后,建议成立一个特别委员会,进行彻底研究并提出建议。

期刊介绍: The Canadian Journal of Soil Science is an international peer-reviewed journal published in cooperation with the Canadian Society of Soil Science. The journal publishes original research on the use, management, structure and development of soils and draws from the disciplines of soil science, agrometeorology, ecology, agricultural engineering, environmental science, hydrology, forestry, geology, geography and climatology. Research is published in a number of topic sections including: agrometeorology; ecology, biological processes and plant interactions; composition and chemical processes; physical processes and interfaces; genesis, landscape processes and relationships; contamination and environmental stewardship; and management for agricultural, forestry and urban uses.
