Lime and biochar are widely utilized to enhance nitrogen utilization in crops grown on acidic soils, though each has its own set of limitations. Understanding their combined effects is crucial for optimizing soil remediation strategies. This study investigates the impact lime efficiency (NUE) a tobacco monoculture system, which been practiced 20 years acidified soils Fuzhou, southeastern China, over period from 2021 2022. Four treatments were applied: control (CK), alone (L), (B), lime-biochar combination (L+B). The results indicated that all significantly improved NUE, with increases ranging 20.07% 27.17% compared CK. Biochar (B) was more effective than treatment (L+B) showed comparable alone. Correlation analysis revealed pH exchangeable base cations facilitated transformation, thereby enhancing NUE. (L, L+B) promoted nitrification potential rhizosphere soil, whereas application (B, resulted elevated nitrate content. Microbial functional enhanced nitrification, while fostered dissimilatory reduction, improving retention. Pearson correlation demonstrated strong positive relationship between reduction both alkali-hydrolyzable contents. These findings suggest enhances promotes retention, together increasing availability. integrates these benefits, yielding offers valuable insights into synergistic use mitigating acidification management agricultural systems.

Abstract Nitrate ammonification is important for soil nitrogen retention. However, the ecology of ammonifiers and their prevalence compared with denitrifiers, being competitors nitrate, are overlooked. Here, we screen 1 million genomes nrfA onr , encoding ammonifier nitrite reductases. About 40% assemblies carry at least one denitrification gene show higher potential nitrous oxide production than consumption. We then use a phylogeny-based approach to recruit fragments nrfA, reductase genes ( nirK nirS ) in 1861 global terrestrial metagenomes. outnumbers nearly negligible counts all biomes, but dominate, except tundra. Random forest modelling teases apart influence C/N on -ammonifier vs denitrifier abundance, showing an effect nitrate rather carbon content. This study demonstrates multiple roles play cycling identifies factors ultimately controlling fate nitrate.

Bioreduction of nitrate to value-added ammonium is a potentially sustainable strategy recycle nutrients from wastewater. Here, we have proven the feasibility reduction autotrophic with electrons extracted Fe(0). Using Geobacter-dominated anodic biofilm as an inoculum, achieved nitrate-to-ammonium efficiency up 90 ± 3% rate 35 1.3 mg N/d/L. An electron acceptor instead inoculum greatly influenced Fe(0)-dissimilatory (DNRA), where nitrite provided effective selective pressure enrich Geobacter initial 5 56%. The DNRA repressing denitrification was demonstrated by reverse tendencies upregulated nrfA and downregulated nirS gene transcription. This finding provides new route for removal recycling water, which has broader implication on biogeochemical nitrogen iron cycling.

The dynamics of the physiological adaptability plants and rhizosphere soil environment after waterlogging remain unclear. Here we investigated mechanisms regulating plant condition shaping microbiome in a pot experiment. In experiment, added melatonin to waterlogged plants, which promoted relief. treatment significantly enhanced photosynthesis antioxidant capacity apple nitrogen (N) utilization efficiency by upregulating genes related N transport metabolism. Multiperiod analysis showed dynamic effects on diversity microbial community during recovery. Random forest linear regression analyses were used screen for potential beneficial bacteria (e.g., Azoarcus, Pseudomonas Nocardioides) specifically regulated revealed positive correlation with nutrient levels growth. Furthermore, metagenomic regulatory involved cycling soil. Melatonin positively contributed accumulation dry weight expression nifD nifK (N fixation). summary, regulates functions structure function community; it recovery stress.
