粘粒是土壤具有许多物理、化学性质的根源,这些性质使土壤能成为作物生长的良好场所及废物处置介质。土壤中的粘粒矿物与天然矿物相比有其特殊性。粘粒的阳离子交换性能为土壤能吸持植物养分离子最重要的性质之一,其离子吸附选择性在土壤作为生长作物和处置废物介质中有一定作用。土壤层状硅酸盐中的原生态K是伊利和云母提供作物生长的主要元素。粘粒的分散和絮凝是影响土壤结构、脆性等性质的重要因素。蛭石和蒙皂石的阳离子交换位通常存在Al~(3+)或聚合Al。氧化铁与土壤的颜色、团聚作用、吸附性能有关。氧化锰与微量元素的吸持及Fe的氧化有关。锂硬锰矿是土壤中的另一类矿物。
Clumps are a source of many physical and chemical properties of soils that make the soil a good place for crop growth and waste disposal media. Soil clay minerals and natural minerals compared to its particularity. Cation exchange performance of clay is one of the most important properties that soil can absorb plant nutrient ions. Ion adsorption selectivity plays a role in the soil as a growing crop and disposal waste medium. The protista K in soil phyllosilicates is a major element of the crop growth that Erie and mica provide. The dispersion and flocculation of clay particles is an important factor affecting the soil structure, brittleness and other properties. Vermiculite and smectite cation exchange sites usually exist Al ~ (3 +) or polymeric Al. Iron oxide and soil color, agglomeration, adsorption performance. Manganese oxide is associated with the adsorption of trace elements and the oxidation of Fe. Lithium-manganese ore is another type of mineral in the soil.
