The spatial distribution of soil microarthropods in soybean fields was investigated by use of a modified Tullgren extractor. Blocks of soil were extracted over a grid of collection cells from which microarthropod aggregations could be identified and measured. Aggregations in conventionally tilled soybeans were smaller than those in no tillage soybeans, and had less influence on population distributions. Population size was highly correlated with the area of soil microarthropod aggregations. 10 references, 5 figures, 3 tables.
