Mollisols are naturally fertile soils with a thick, friable, very dark coloured, organic rich, surface layer (mollic epipedon). Soils literature for 20 South Pacific island countries was examined for information on Mollisols; of these countries, 16 had confirmed Mollisols. Given the basic concept of Mollisols (continental grassland soils), this was an unexpected prevalence. Classifications using the USDA Soil Taxonomy identified 4 suborders, 10 great groups, and 33 subgroups of Mollisols occurring in the South Pacific region. Some taxonomic issues were identified, and these are addressed and changes to better accommodate Mollisols important for the South Pacific region are suggested. The importance of Mollisols in the region is summarised by reviewing their occurrence and uses, especially in food production.

软体动物是天然肥沃的土壤，具有厚的，易碎的，非常深色的，有机丰富的表层（分子表皮）。检查了20个南太平洋岛国的土壤文献，以获取有关Mollisols的信息。在这些国家中，有16个已确认了Mollisols。考虑到Mollisols（大陆草原土壤）的基本概念，这是一种出乎意料的流行。使用美国农业部土壤分类法进行的分类确定了南太平洋地区出现的4个亚类，10个大类和33个亚类的Mollisol。确定了一些分类学问题，并加以解决，并建议进行修改以更好地容纳对南太平洋地区重要的Mollisol。通过回顾它们的发生和用途，特别是在粮食生产中，总结了该地区的重要性。
