“…Averaged across soil depths, MCS and MWMb accumulated relatively higher WBC compared with MMuMb and MMS which indicate that inclusion of chickpea or wheat as rabi crop appeared to be a superior option compared to mustard or winter maize as far as SOC accumulation is concerned. The finding of present study is in line with the published literature on depthwise distribution of SOC in crop lands (Mandal et al, 2013;Singh et al, 2015). This study corroborated the findings of Bhattacharyya et al, (2012) suggesting thereby the advantage of minimum soil disturbance (PB and ZT) and crop wise residue retention on soil surface.…”

“…However, we excluded papers based solely on indirect population assessment methods such as earthworm surface casts, middens and macropores (e.g. Miura et al, 2008;Singh et al, 2015). Studies were collected from peer-reviewed journals, as well as other sources such as book chapters, PhD dissertations, project reports and conference papers, as a recommended approach to reduce publication bias (McAuley, Pham, Tugwell, & Moher, 2000).…”

AbstractThe adoption of less intensive soil cultivation practices is expected to increase earthworm populations and their contributions to ecosystem functioning. However, conflicting results have been reported on the effects of tillage intensity on earthworm populations, attributed in narrative reviews to site-dependent differences in soil properties, climatic conditions, and agronomic operations (e.g., fertilization, residue management and chemical crop protection).We present a quantitative review based on a global meta-analysis, using paired observations from 215 studies performed over 65 years across 40 countries on five continents, to elucidate this long-standing unresolved issue. Results showed that disturbing the soil less (e.g., no-tillage and Conservation Agriculture) significantly increased earthworm abundance (mean increase of 137% and 127%, respectively) and biomass (196% and 101%, respectively) compared to when the soil is inverted by conventional ploughing. Earthworm population responses were more pronounced when the soil had been under reduced tillage for a long time (>10 years), in warm temperate zones with fine-textured soils, and in soils with higher clay contents (>35%) and low pH (<5.5). Furthermore, retaining organic harvest residues amplified this positive response to reduced tillage, whereas the use of the herbicide glyphosate did not significantly affect earthworm population responses to reduced tillage.Additional meta-analyses confirmed that epigeic and, more importantly, the bigger-sized anecic earthworms, were the most sensitive ecological groups to conventional tillage. In particular, the deep burrower Lumbricus terrestris exhibited the strongest positive response to reduced tillage, increasing in abundance by 124% more than the overall mean of all 13 species analysed individually. The restoration of these two important ecological groups of earthworms and their burrowing, feeding and casting activities under various forms of reduced tillage will ensure the provision of ecosystem functions such as soil structure maintenance and nutrient cycling by "nature's plough".

“…While numerous studies conducted in arable fields showed a trend towards detrimental tillage effects on earthworms (Emmerling 2001, Singh et al 2015, there are also studies reporting little or even stimulating impacts of tillage on earthworms. Earthworm abundance was similar between reduced tillage and mouldboard ploughing (Crittenden et al 2014).…”

Inter-rows in vineyards are commonly tilled in order to control weeds and/or to conserve water. While impacts of tillage on earthworms are well studied in arable systems, very little is known from vineyards. In an experimental vineyard, the impact of four reduced tillage methods on earthworms was examined: rotary hoeing, rotary harrowing, grubbing and no tillage. According to an erosion prevention programme, tillage was applied every other inter-row only while alternating rows retained vegetated. Earthworms were extracted from the treated inter-rows 10, 36, 162 and 188 days after tillage. Across dates, tillage methods had no effect on overall earthworm densities or biomass. Considering each sampling date separately, earthworm densities were affected only at day 36 after tillage leading to lower densities under rotary hoeing (150.7 ± 42.5 worms/m2) and no tillage (117.3 ± 24.8 worms/m2) than under rotary harrowing (340.0 ± 87.4 worms/m2) and grubbing (242.7 ± 43.9 worms/m2). Time since tillage significantly increased earthworm densities or biomass, and affected soil moisture and temperature. Across sampling dates, earthworm densities correlated positively with soil moisture and negatively with soil temperature; individual earthworm mass increased with increasing time since tillage. It was concluded that reduced tillage in vineyards has little impact on earthworms when applied in spring under dry soil conditions.
