“…This could explain why it acted as the biomarker for W4MF. Biomarker Glomeromycota contained many members of arbuscular mycorrhizal fungi, which form symbiosis with plant roots to supply nutrients and increase the plant's tolerance to environmental stresses (Kiers et al, 2011; Rivera‐Becerril et al, 2017). For the sole biochar‐treated group, the biomarkers were Zygomycota and Agaricomycetes (Fig.…”

Biochar‐based fertilizer treatments induced significant microbial community structure shifts compared with no‐biochar and biochar alone. Biochar‐based fertilizer especially at higher biochar addition rate increased soil microbial biomass and fertility. Soil microbial species were strongly correlated with soil nutrients under biochar and biochar‐based fertilizer into karst soil. Karst ecosystems are vulnerable to degradation and constitute a significant proportion of southwestern China. Here, we explore the amendment of these soils with wood biochar in combination with N‐P‐K fertilizer and swine manure compost with the goal of improving microbial community structure and soil nutrient status of these soils. A pot experiment with six treatments, including control (CK, no amendment), swine manure compost plus N‐P‐K fertilizer (MF), wood biochar at 2% in soil (W2), wood biochar at 4% in soil (W4), wood biochar‐based fertilizer at 2% in soil (W2MF), and biochar‐based fertilizer at 4% in soil (W4MF), was set up for 20 months. The results showed that soil organic matter and soil available nutrients N, P, and K in W4MF increased by 63.95, 66.23, 284.96, and 94.56%, respectively, compared with CK. Soil microbial biomass C, N, and P increased in sequence by 60.05, 87.64, and 307.85%, respectively. Soil bacterial and fungal diversity indices (Simpson and Shannon) and richness index (Chao1) were generally higher in biochar‐based fertilizer treatments (W2MF and W4MF) than biochar alone (W2 and W4). The bacterial and fungal community structures of biochar based fertilizer treatments differed from those of biochar amendment alone or control (P < 0.05). Linear discriminant (Effect Size) analysis showed that the bacterial biomarkers of the W2MF + W4MF group were mainly the phylum Acidobacteria and class Alphaproteobacteria, and the fungal biomarkers were the phylum Rozellomycota and Glomeromycota. Redundancy analysis revealed strong relationships between microbial community structure and soil organic matter and soil available nutrients N, P, and K (P < 0.05). In conclusion, either sole biochar or biochar‐based fertilizer amendment improved karst soil nutrient conditions and induced microbial community structural shifts. The performance was better in biochar‐based fertilizer treatment than that in biochar addition alone.

“…There is considerable research focusing on the effect of herbicides and insecticides on soil microbial communities 27, 45–48 , compared to fungicides which have been reported to induce more non-harmful effects on soil microbical communities 6, 46, 49, 50 . Direct or indirect application of fungicides can have an adverse impact on soil microbiomes which serve to defend the soil borne fungal pathogens 51 .…”

Considering the fact that biopesticides are increasingly used to replace synthetic pesticides in pest control, it is necessary to assess their ecotoxicity and especially their non-target effects on soil microorganisms, which is largely unknown. In this study, the effects of the synthetic pesticide carbendazim and the biopesticides (cantharidin and norcantharidin) on soil microbial parameters in a silt loam soil were evaluated. By using commercial formulations at the recommended and higher rates, both cantharidin and norcantharidin induced adverse effects on soil invertase, phosphatase activities and fungal gene structure, but these changes were transient. After about two weeks, the harmful effects owing to the application of pesticides phased out and eventually became comparable with non-treated samples. The degradation of cantharidin and norcantharidin was rapid and can be completed within a few days in the soil. None of the three pesticides caused significant shifts in urease activity. This study provides a comprehensive assessment of the soil microbial toxicity of these biopesticides for reasonable and efficient usage.

“…As recently reviewed, this persistence and the bioavailability depend greatly on environmental factors, physico‐chemical properties of the substance, soil type, soil pH, moisture, organic matter and the ability of the local soil microflora to degrade the respective substance . The fate of pesticides in the soil is beyond the scope of this review, but we would like to point out that variations in pot and field experiments can be caused, apart from other things, by differences in soil parameters …”

“…However, the availability of AMF‐specific primer sets, together with different high‐throughput sequencing tools, allows for monitoring of the effects of pesticides on AMF communities in the field . Furthermore, the use of quantitative PCR allows quantitative monitoring of key taxa . Based on these tools, there is evidence that AMF taxa react differently to certain pesticides in relation to their mode of action and concentration .…”

Arbuscular mycorrhizal fungi (AMF) form symbioses with the majority of plant species and can provide multiple benefits to the host plant. In agro‐ecosystems, the abundance and community structure of AMF are affected by agricultural management practices. This review describes and discusses current knowledge on the effects of inorganic and organic chemical pesticides on AMF in the conflicting area between agricultural use and environmental concerns. Variable effects have been reported following chemical pesticide use, ranging from neutral to positive and negative. Moreover, a species‐specific reaction has been documented. The reported effects of pesticides on arbuscular mycorrhizal symbiosis are very diverse, and even when the same substance is investigated, the results are often contradictory. These effects depend on many parameters, such as the active substance, the mode of action, the mode of application and the dosage. In the field, determinants such as the physico‐chemical behavior of the active substances, the soil type and other soil microorganisms contribute to the fate of pesticides and thus the amount of active substances to which AMF are exposed. This review highlights that the fate of AMF following pesticide use needs to be addressed in a broader agro‐ecosystem context. © 2018 The Authors.
