Abstract

As the soil invertebrate fauna is expected to modify several properties ofupland soils in agriculture, the effect of the soil fauna on the soil properties and soybean growth under several kinds of soil management depending on the soil type, nitrogen source, tillage, insecticide and herbicide was investigated. Number of hand-sorted earthworms was positively correlated with the amount of soil aggregates (> diam. 2 mm) (r = 0.85, p < 0.01), and that of oribatid mites (Acari: Cryptostigmata) extracted by using modified Tullgren funnels was positively correlated with the nitrate nitrogen concentration in the soil (r = 0.89, p < 0.01). Number of oribatid mites was positively correlated with the content of total soil nitrogen and the content of total soil carbon in a Gray Lowland soil (both: r = 0.99, p < 0.01) and a Brown Forest soil (not significant), but negatively in an Andosol. The stem length of soybean cultivated on those soils showed a positive correlation with the number of earthworms (r = 0.54, p < 0.05) and oribatid mites (r = 0.62, p < 0.05), while the stem weight of soybean with the number of macrofauna organisms (r = 0.61, p < 0.05) and earthworms (r = 0.8, p < 0.01), respectively. The correlations between the number of soil invertebrates and yield or quality of soybean grain were not significant in this survey.
