14种土壤的粗粒机械分离物（2-50 μm和>50 μm）中含有大量的粘粒（<2 μm），它们代表7个分类目，具有广泛的质地和性质差异，发育于不同的成土环境。多元回归分析的数据清楚地表明，无定形铁和Alorganic C-粘土相互作用，在稳定的大小分离。此外，从回归分析中获得的“β”系数已经给出了一个洞察的相对重要性的无定形铁和铝的氧化物，有机质和粘土在稳定的机械分离。
Significant amounts of clay (<2 μm) fraction were found to be present in the coarse-size mechanical separates (2–50 μm and >50 μm) of fourteen soils, which represent seven taxonomic orders and have widely varying texture and properties and developed under different pedogenic environments. Multiple regression analyses of the data clearly show the amorphous Fe and Alorganic C-clay interaction in stabilizing the size separates. Furthermore, the “beta” coefficients obtained from the regression analyses have given an insight into the relative importance of the amorphous Fe and Al oxides, organic matter and clays in the stabilization of the mechanical separates.
