- The soil organo - mineral complexes , formed by intimate association of organic matters or humic substances and mineral , is one of the fundamental features that distinguishes soils from their geological parent materials , and effects on the nature of soil aggregate , and the amounts and characters of soil particle aggregation is closely related to soil fertility . by way of collecting soil samples outdoors and analysis indoors and using the dry land soils developed from purple soils as research materials , this paper investigated status of organo - mineral complexion , characters of aggregation and soil fertility for discussing the relationship among them under different land treatments , and the factors that influencing the amounts and characters of organo - mineral complexion and soil aggregation and restricting status of soil fertility , the main results were as follows : there were remarkable differences of status and activity of fe oxide and aluminum oxide in dry land soils developed from different parent soils and under different utilizations
土壤中有机物质和矿物质的结合?土壤有机无机复合体是土壤区别其母质的基本特征之一，它对土壤团聚体的性质有很大的影响，而团聚体的数量和性状有跟土壤肥力密切相关，本文以不同母岩发育的旱地紫色土作为研究材料，通过野外采样和室内分析，研究了旱地紫色土的有机无机复合状况、团聚体特征和肥力水平，探讨了在不同土地利用方式下它们之间的关系，以及影响有机无机复合、土壤中团聚体的数量、性质以及制约土壤养分状况的因素，主要结果如下：不同类型的紫色土铁铝氧化物形态和活性具有很大差别。
