ABSTRACT

In India, there have been very few studies to quantify the effects of soil macrofauna activity in farmland, and on the effects of farm
practices on the structure and function of soil arthropod populations. Thus, the present investigation was undertaken and efforts were
made to assess the response of soil-surface arthropod population densities across 15 different soil management treatments. The
relative population density of soil-surface inhabiting arthropods were monitored using pitfall traps. Pitfall traps have been used often
in studies examining the occurrence and activity of epigeic-invertebrates. These arthropods were sampled in each plot every month
during three seasons, i.e., rainy (June to September,) post rainy (October to January) and summer (February to May) seasons. Each
pitfall trap consisted of a glass jar (12 cm high with a diameter of 5 cm at the mouth), which was sunk into the ground so that its
upper rim (mouth of the bottle) was flushed with the soil surface. The mean density of total arthropods were significantly low in
annual treatments compared with those of the perennial ley treatments. Under the annual crop, in zero-tillage treatments, the density
was low in bare amendment while it was high in rice-straw amendment. In shallow-tillage treatments, it was lower in rice-straw
amendment and increased to 22 in bare amendment, In deep-tillage treatments, it was low in bare amendment, which increased to
28 in farmyard manure amendment. In perennial ley treatments, the density was low in C. ciliaris + S. hamata treatment, which
reached 35 in pigeon pea + S. hamata treatment.
