Applying PB alone or with biochar increased the level of root colonization by AMF compared with the control and biochar-only application in soybean but not in corn. Overall, biochar and PB application had no significant effect on bacterial and AMF diversity and community structure compared with the control. However, applying PB alone or with biochar decreased the fungal alpha diversity (Shannon and Simpson indices), affected several fungal taxa abundances and shifted the fungal community structure as indicated by the principal coordination analysis (PCoA).

Soil nematodes are the most abundant animals and occupy multiple trophic positions, providing an excellent method to study energy transfer processes in soil micro-food webs. However, the driving mechanisms underlying the evolution of soil nematode energy flux during natural forest restoration remain poorly understood. Here, we selected an undisturbed native forest and four natural secondary forests (20, 32, 47, and 61 years) at different recovery stages as study sites to assess the effects of forest restoration on soil nematode community structure and energy flux. Results showed that forest restoration increased the abundance and diversity of nematode communities, but different trophic groups exhibited varying responses to forest restoration. The improvement of resources and abiotic environment was a key factor in increasing nematode abundance and diversity. The increase in root biomass and microbial biomass promoted the abundance of herbivores and microbivores, further leading to an increase in the number and diversity of omnivores-predators. The total energy flux of nematode community increased with forest restoration. Compared to 20 years, the total energy flux increased by 4.12 %, 132.56 %, and 176.68 % in 32, 47, and 61 years, respectively. However, they were all significantly lower than in the primary forest stage. Multiple regression analysis showed that soil properties, microbial characteristics, and root biomass contributed most to omnivores-predators and total energy flux. The random forest analysis showed that omnivores-predators, herbivores, and root biomass were the most important biotic factors in predicting soil nematode energy flux, together explained 32.8 % of the total energy flux variation. Meanwhile, soil organic carbon (SOC) and mean weight diameter (MWD) were identified as the most important abiotic factors for predicting nematode energy flux, together explained 10.1 % of the total energy flux variation. Microbial resources (microbial biomass) mainly indirectly regulate total energy flux by affecting the microbivores. These results provide direct evidence that, as forest restoration progresses, improved nutrient availability (e.g., SOC) and soil physical conditions (e.g., MWD), along with strengthened trophic interactions within the nematode community (e.g., predator-prey dynamics), collectively drive the overall energy flux within the nematode assemblage.</div></div>","PeriodicalId":8099,"journal":{"name":"Applied Soil Ecology","volume":"204 ","pages":"Article 105699"},"PeriodicalIF":4.8,"publicationDate":"2024-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142535982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fertilizations provoke high dependency on nutrient inputs and produce changes in nutrient dynamics, microbial activity, and the composition of soil microbial communities. However, few studies evaluate the high dependency on nutrient inputs with biogeochemical, and enzymatic variables and link the results with nutrient stoichiometry analyses to understand the effect on nutrients availability, microbial activity and biogeochemical cycling. The aim of this work was to analyse the effect of agricultural land use and fertilization with organic and inorganic P on soil nutrient dynamics (C, N and P) in Andosols. We divided the article into three sections, the first one that identifies the effect of land use change on biogeochemical, enzymatic activities, and ecological stoichiometry variables and identifies the dominant processes in each plot to answer: does the sites work as open or closed systems in terms of nutrient exchange and energy? The second section uses the results obtained in section one in order to identify the stability of the biogeochemical variables individually due to the change in land use, calculates resistance and resilience indices, and finally, the third section, covers an incubation experiment on soils from an agricultural site and a pine-oak site, which were fertilized with organic and inorganic compounds with the same concentration of P. At the end of this experiment, the changes in microbial activity and biogeochemical and ecological stoichiometric variables, such as threshold element ratio (TER) were identified, contributing with our data to increase the knowledge about the effects of the changes in soil elemental stoichiometry associated to fertilization, on resistance and resilience of soil organic matter transformation, soil nutrients availability and enzymes synthesis. With the variables analysed in these sections we aim to answer the following questions: will organic agriculture modify the stability of soil nutrient transformation, organic nutrient stores and activity of enzymes that degrade organic matter? and, what effects will fertilization have on the enzymatic activities linked to phosphorus?

In order to better support the ecological transition towards an organic agriculture in tropical agroecosystems, it is important to better understand the links between agricultural practices, soil macrofauna and the decomposition process. To reach this goal, we conducted a field experiment in banana agroecosystems in Martinique (Lesser Antilles). We selected six organic and six conventional banana fields located in two bioclimatic zones. In order to measure the microbial and macrofaunal contribution to decomposition, 264 litterbags, with either a small or large mesh size, were positioned and left in the field for three months. Glyphosate-contaminated and glyphosate-free banana leaf litters were tested. Biotic and abiotic field characteristics were measured. Our results confirmed the overall beneficial effect of converting to organic agriculture on the decomposition process (+24 %) for bananas leaf litter. Macrofaunal decomposition was increased more (55 %) than microbial decomposition (20 %), indicating that organic farming removes a constraint of conventional farming especially affecting macrofauna. Glyphosate contamination of the litter did not have a significant effect on overall litter decomposition. By using structural equations, we were able to link farming practices to macrofauna diversity and to decomposition process, through a cascading chain of effects. We found that organic farming enhanced macrofaunal contribution to decomposition by enhancing both macro-arthropod and earthworm richness by providing a diversity of microhabitats with dense and species-rich plant cover. Our results suggested a weak effect of the direct toxicity by glyphosate-contaminated litter ingestion, but an indirect effect of herbicides by destroying the soil weed cover providing resources and microhabitats for soil macrofauna.

We know that soils are highly vulnerable to warming in terrestrial ecosystems. However, it remains unclear whether the legacies of pre-existing global changes can exacerbate the responses of soil biodiversity and function to warming. To address this knowledge gap, we conducted a four-month growth chamber experiment to investigate the responses of soil biodiversity - focusing on three fungal functional groups (soil pathogen, saprotroph and ectomycorrhizal richness) and soil multifunctionality (measured by seven enzyme activities associated with C, N, P, and S cycling) to simulated warming. The soils were collected from four groups of global change located within the same experimental station in Australia, which were subjected to multiple global change factors, including CO₂ enrichment, altered precipitation patterns, irrigation and fertilization, and nutrient addition. In general, soil biodiversity and multifunctionality in soils previously subjected to global changes were more susceptible to warming than those in control soils (i.e., without pre-existing global changes). Different biotic and abiotic factors drove multifunctionality under ambient and warming conditions. Specifically, soil ectomycorrhizal diversity, primarily driven by soil pH, had a more significant positive influence on soil multifunctionality than soil properties under ambient conditions. These findings suggest that environmental filtering may also regulate the biodiversity of fungal functional groups and functions in soils subjected to pre-existing global changes. While under warming conditions, soil dissolved organic C was more important than soil biodiversity (i.e., saprotroph richness) in affecting soil multifunctionality. Our results demonstrate that the legacies of global changes may weaken the positive effects of soil biodiversity and its interactions with soil physicochemical properties in regulating soil functions in response to warming.

Several studies explored PAHs remediation using varied methods, each with merits and drawbacks. This review compiles diverse methods, offering an overview of multidimensional approaches for remediating PAH-contaminated soils, with a particular emphasis on hybrid technique. The exploration comprehends physical techniques like thermal desorption and electrokinetic remediation, chemical methods including oxidation and photocatalytic remediation, and biological approaches such as phytoremediation and microbial degradation. The integration of these diverse methods reflects a holistic and sustainable approach to address the challenges posed by PAHs-polluted sites. Phytoremediation is eco-sustainable, cost-effective, but time-consuming, while hybrid approaches offer enhanced PAH removal in short time. In comparison to microbial degradation and advanced computational methods, thermal and electrokinetic methods are costly and less eco-friendly.
