“…Crotty et al (2016) found that in comparison to other, mainly non-leguminous preceding forage species, only white clover alleviated the detrimental effect of conventional ploughing on all earthworm ecological groups. The latter two studies did not find residue retention (Melman et al, 2019) or cropping system (conventional, feed, biogas; Denier et al, 2022) to alleviate the detrimental effect of intensive tillage on earthworms. However, in the first case, the only crop species was corn (Zea mays), and in the latter, crop rotations in all systems included several legume species.…”

“…There is also evidence that increased inputs of high quality food resources such as manure (Simonsen et al, 2010) and legume residues (Ashworth et al, 2017), are especially beneficial for endogeic earthworms. In addition to our study, Crotty et al (2016), Melman et al (2019) and Denier et al (2022) compared tillage to another type of agricultural management in a multifactorial experiment. Crotty et al (2016) found that in comparison to other, mainly non-leguminous preceding forage species, only white clover alleviated the detrimental effect of conventional ploughing on all earthworm ecological groups.…”

“…Although such studies are few, some examples exist. For example, Melman et al (2019) and Denier et al (2022) did not find residue retention or cropping system (conventional, feed or biogas), respectively, to enhance earthworm densities under conventional tillage. On the other hand, Crotty et al (2016) found that, in comparison to other forage crops, a legume (Trifolium repens) buffered the reduction in earthworm densities during the first year after conversion from forage to annual cereals both with conventional and no tillage, although the differences in anecic densities after conversion were not statistically significant between the preceding forage species.…”

Intensive agriculture is detrimental to soil biodiversity and functioning. Promoting communities of key soil organisms, such as earthworms and arbuscular mycorrhizal (AM) fungi, may help improve agricultural sustainability by replacing inputs with ecosystem services. In this thesis, I explore ways to manage earthworm communities for improved soil functioning via adjusted agricultural practices, promotion of source habitats in the landscape, and inoculation. I also explore the effects of soil compaction on AM fungal symbiosis in wheat varieties, and test application of grassland soil as a method to increase AM fungal diversity in agricultural soils. I show that diverse earthworm communities and bioturbation can be promoted by reducing tillage intensity and total earthworm densities can be increased via diversifying crop rotations. Moist and fertile semi-natural grasslands with high small-scale habitat heterogeneity may serve to sustain earthworm diversity in agricultural landscapes. Inoculation with commercially obtained Lumbricus terrestris earthworms may help restore populations of this tillage sensitive species and improve wheat growth but the long-term establishment of these worms is uncertain. Application of grassland soil may increase AM fungal diversity in agricultural soils but this may not be reflected in AM fungal taxa colonizing wheat roots. I also show that soil compaction differently affects AM colonization in wheat varieties. Further research needs to identify which earthworm and AM fungal community properties best result in functional benefits under different conditions. Nevertheless, I show that earthworm and AM fungal communities can be promoted in various ways, individually or in combination, suggesting potential to enhance functional effects of these key organisms in agricultural soils.

“…However, divergent results have also been found among studies (Brennan et al 2006;Scheunemann et al 2015;Coulibaly et al 2017) and were mainly attributed to differences in crop residue quantity and quality (Sauvadet et al 2016). In addition, bene cial effects of crop residue management may be overridden by tillage practices and be therefore mainly observed under no-till systems (Denier et al 2022).…”

AimConservation agriculture is increasingly adopted to improve soil fertility and reduce the depressive effects of intensive farming on soil functions and associated services. However, conservation agriculture systems may greatly differ from each other by their age and the quantity and the quality of cover crops and the effects of these variables on soil fauna are still poorly known. Here, we aim at gaining insight into the impact of conservation agriculture on soil mesofauna and macrofauna communities at the cropping and farming system levels. MethodCollembola and earthworm communities were compared in seven neighbouring pairs of elds (same topography, spring crop and soil type) being either under conventional systems, or under conservation agriculture systems with intermediate autumn cover crops. ResultsConservation agriculture systems positively in uenced soil mesofauna and macrofauna communities compared to conventional systems. The bene cial effects of conservation agriculture on earthworm communities were predominantly related to the lower soil physical disturbance (no-tillage) while Collembola were also positively affected by cover crop characteristics and the age of the practice. ConclusionsThe adoption of conservation agriculture systems may improve earthworm and Collembola abundance and represents thus an innovative opportunity for sustainable crop production through the preservation of soil biodiversity. In addition, our ndings suggest that both earthworms and Collembola may be used as indicators for agri-environmental management at the cropping system level.

Combined intensive management of fertilization, tillage, and organic material mulching regulate soil bacterial communities and functional capacities by altering soil potassium and pH in a Moso bamboo forest

Intensive management is a common practice in agricultural and forestry ecosystems to improve soil quality and crop yield by influencing nutrient supply and soil microbiota; however, the linkage between soil nutrients and bacterial community and functional capacities in intensively managed economic forests has not been well studied. In this study, we investigated the soil properties such as available potassium (AK), available nitrogen (AN), available phosphorus (AP), ammonium (NH4+), nitrate (NO3-), organic matter (OM), total nitrogen (TN), total phosphorus (TP), bacterial diversity and community composition, potential functions of rhizome roots, and soil microbiota across a chronosequence of intensively managed Moso bamboo (Phyllostachys edulis) forests. Our results demonstrated that the combined intensive management (deep tillage, fertilization, and organic material mulching) in this study caused a significant increase in the concentrations of AK, AN, AP, NH4+, NO3-, OM, TN, and TP (P < 0.05). However, they led to a remarkable decrease in pH (P < 0.05). Such changes lowered the Shannon diversity of the soil and rhizome root microbiota but did not significantly affect the community composition and functional capacity. Soil bacterial community variation was predominantly mediated by soil total potassium (TK) (15.02%), followed by pH (11.29%) and AK (11.13%). We further observed that Nitrospirae accounted for approximately 50% of the variation in soil pH, NO3-, NH4+, and AK, indicating its importance in soil nutrient cycling, especially nitrogen cycling. Accordingly, we propose that the management-induced changes in soil parameters reshaped the bacterial community structure and keystone bacterial assemblage, leading to the differentiation of microbial functions.
