Abstract Background Hundreds of millions tons coal fly ash are produced annually to support economic development and industrial production. However, directly applying agricultural production can decrease the land productivity pose a threat ecosystem due poor physicochemical properties seriously heavy metal pollution. Methods In this study, field experiment investigate effects as soil amendment was conducted in Hebei province, China. The (CFA) mixed with carrier (CS, without containing ash) at different rates (0–40% mass content) 0–20 cm layer top then rotovator. amended 0.45–1.80 kg·m − 2 G1 for planting corn. Purpose purpose study is response mechanism microbial community activities, soil. Key results found that amendment, which consisted humic acid, polyacrylamide, zeolite powder, FeSO 4 ·7H O, improved chemical physical structure by increasing bulk density macroaggregates. highest corn yield observed B5 (20% CS 1.3500 G1). Meanwhile, abundance microorganisms facilitate circulation nutrients such Acidobacteria (77.05%), Sphingomonas (25.60%), Nitrospira (20.78%), Streptomyces (11.32%), Gaiella (10.20%) increased. Conclusions Overall, our indicate use enhance sustainability improving functions. These findings provide reference application amendments.

Diversified Vegetation Cover Alleviates Microbial Resource Limitations within Soil Aggregates in Tailings

Environmental Science & Technology, Год журнала: 2024, Номер 58(42), С. 18744 - 18755

Resource demand by soil microorganisms critically influences microbial metabolism and then ecosystem resilience multifunctionality. The ecological remediation of abandoned tailings is a topic broad interest, yet our understanding metabolic status in restored soils, particularly at the aggregate scale, remains limited. This study investigated resources within aggregates from revegetated applied vector model ecoenzymatic stoichiometry to examine how different vegetation patterns (grassland, forest, or bare land control) impact resource limitation. Five-year restoration significantly elevated carbon (C) nitrogen (N) concentrations their stoichiometric ratios (approximately 2-fold), although these increases were not translated biomass its stoichiometry. activities C- phosphorus (P)-acquiring extracellular enzymes increased substantially postvegetation, with most pronounced escalation macroaggregates (>0.25 mm). results indicated was colimited C P, acutely microaggregates (<0.25 colimitation exacerbated monotypic cover but mitigated under diversified cover. Soil nutrient controlled limitation, overshadowing heavy metals. Our findings underscore that optimizing allocation through strategic revegetation can enhance tailings, which advocates for implementation diverse covers as viable strategy improve development degraded landscapes.

Changes in vegetation communities are projected to have a greater impact on the turnover and storage of carbon coastal wetlands by affecting soil organic matter decomposition.Microbial metabolism regulates process decomposition soil.However, there is still need for mechanistic framework predict effects changes microbial metabolism.Hence, this study aimed evaluate changing trends metabolic limitation use efficiency under natural succession community degradation wetland using extracellular enzyme ecological stoichiometric ratios.The results showed that microorganisms at sites experienced higher limitations compared others.Microbial was significantly lower (p<0.05).A trade-off between observed, as these two factors were negatively associated.Furthermore, strong correlation with pH.These findings suggest that, balance mitigate adverse pH changes, allocate more from toward production relevant enzymes.
