晚更新世黄土母质发育土壤的磷含量普遍低于其它母质类型。

Late Pleistocene loess parent material in soils of the phosphorus content is generally lower than in other types of parent material . 5 .

在红棕色粘黄土母质上发育的黄褐土和水稻土，粘粒矿物仍以水云母为主，但含有较多量的高岭石和蒙脱石；

While the yellow cinnamon soil and paddy soil developed on red & brown clay loess are chiefly of hydromicas with more kaolinite and montmorillonite .

石灰性母质发育土壤C-O-S含量显著大于黄土母质发育的土壤。

The contents of C O S in soils derived from calcareous parent material was significantly higher than that in soils from loess parent material .
