“…Soil microarthropods are often used as bioindicators of agricultural soil quality. Studies have shown the impacts of soil compaction [7,[12][13][14], and others have compared different agricultural production systems, such as integrated, organic or conventional systems [1,5,6,8]. But, whereas differences in abundance or biomass are often explored, few studies have presented results on diversity.…”

Two crop production systems, which differ on tillage and pesticides, were compared for biodiversity of soil microarthropod communities. A biodiversity index, which integrates different structure and density parameters (abundance, taxonomic richness, taxonomic diversity, coenotic diversity) was used. Results showed a greater biodiversity in minimum tillage systems compared to deep tillage systems. Pesticides seemed to be only a second order factor of variance on microarthropod biodiversity.

“…In terms of biomass, metabolic activity and number, bacteria are the most abundant microorganisms in soil (Brussaard et al ., 1990; Glick, 1995). Most soil bacterial populations are concentrated in the root zone, which is characterized by intense competition amongst microorganisms for nutrients and space (Lynch, 1990).…”

A 2‐year study investigated the relationship between the nematicides aldicarb and fosthiazate and populations of plant growth‐promoting (PGP) and plant‐growth‐inhibiting (PGI) bacteria, and root‐lesion nematodes and bacteria‐feeding nematodes in the root‐zone soils of potatoes. Fewer (P < 0.05) bacterial genera and species were recovered from aldicarb‐treated soils than from the fosthiazate and untreated soils but bacterial population densities were greatest in the aldicarb‐treated soils. In potato plantlet bioassays using root‐zone bacteria from the three soil sources, bacteria from the aldicarb‐treated soils reduced (P < 0.01) the mean wet and dry weight of shoots and roots compared with those from the fosthiazate and untreated soils. In the field, fosthiazate (but not aldicarb) significantly increased tuber yields and reduced nematode population densities of Pratylenchus penetrans in roots and soil. Population densities of bacteria‐feeding nematodes (primarily Diplogaster lheritieri) were not affected by either nematicide. Aldicarb appeared to suppress the populations of plant‐growth‐promoting bacteria that contribute to enhanced growth in potatoes. This is attributed to the long‐term use of aldicarb at the trial site, which may have encouraged the selection, or adaptation, of soil microorganisms that degrade carbamate pesticides but do not enhance potato growth.

“…Conservation tillage practices, such as no‐tillage, are widely used to reduce erosion, improve soil aggregates and save labour and energy (Hernánz et al ., ; Balesdent et al ., ; Six et al ., ; Serraj & Siddique, ). Many previous studies have reported that arthropod density increased under conservation tillage compared with conventional tillage (Wardle, ; Coleman et al ., ; Nakamoto et al ., ; Sapkota et al ., ), but there are also some contradictory results (Brussaard et al ., ; Miura et al ., ). The reason for varied responses may be that the effects of tillage practices on soil moisture, pore continuity and litter accumulation are probably significant, with different orders or species of soil arthropods responding differently to these factors (Kladivko, ; Reeleder et al ., ; Beylich et al ., ; van Capelle et al ., ).…”

Different tillage regimes can change soil micro‐environmental characteristics, which may influence the distribution and abundance of soil arthropods. In this study, soil arthropods and soil properties under a winter wheat–summer maize cropping system were investigated in different tillage regimes over four seasons at two depths. The tillage treatments included conventional tillage (CT), tillage once a year (T1), tillage every two years (T2) and no‐tillage (NT). The results showed that the primary taxa of soil arthropod were Acarina (65.8%), Collembola (28.5%), Diplura (1.4%) and Coleoptera (1%) over the whole sampling period. The total arthropod density was influenced by tillage treatments and season of sampling. Values for CT plots were significantly greater than those for the NT plots in autumn and spring. In contrast, the Shannon–Wiener diversity index (H’) and the evenness index (J) were relatively higher in CT treatment. The Acarina/Collembola (A/C) ratio was significantly smaller in NT treatment for some sampling seasons as mites were more sensitive to tillage practices. The QBS‐ar index did not show a clear pattern among treatments in this study. Soil arthropods notably showed seasonal variation in depth stratification. Relative to CT, the total soil arthropods in the NT plots tended to concentrate in the upper layer due to soil compaction in the lower layer. The climate conditions and soil physical properties were the main factors affecting the soil arthropod distribution and composition, as the soil chemical and microbial properties did not differ significantly among all tillage treatments.
