VARIOUS investigators have emphasized the role of microorganisms in the aggregation of soil particles (4, 5, 8, 13). Among the factors influencing this phenomenon are organic residues, temperature, and moisture content of the soil (7). In general, the effectiveness of molds in aggregation has been shown to be related to their chronological appearance during the decomposition of organic materials in soil (9, 10). The structural condition of soils is also known to be influenced by the relative proportions of fine and coarse particles (3). It may be expected that soil texture in conjunction with the decomposition of organic matter would affect the degree of aggregation brought about by molds. In consequence, the purpose of this study was to investigate the influence of particle size and distribution and type of organic matter on the formation of aggregates by certain mold species.
