Soil amendments have been extensively employed for the purpose of remediating soils contaminated with cadmium (Cd). However, potential impacts soil on chemical properties, Cd bioavailability, total accumulation by rice, and rhizosphere bacterial community in Cd-contaminated paddy fields located a tropical region is still at its infancy. In this study, commercial MgO-CaO-SiO2 conditioner (A), biochar (B), combination ratio 1:1 (C) were applied two different doses [2250 kg ha−1 (A150, B150, C150), 4500 (A300, B300, C300)] to investigate their stabilization uptake rice straw grain remediation field experiment. Rhizosphere diversity composition also assessed using high-throughput sequencing based 16S rRNA genes. Compared non-amendment treatment (CK), pH, cation exchange capacity (CEC), organic matter (OM), nitrogen (TN), available (AN), nitrate (NO3−) concentrations significantly elevated, whereas ammonium (NH4+) reduced amendment treatments. Meanwhile, decreased both grain, lowest concentration C300 treatment. pH CEC negatively associated availability concentrations, while NH4+ was positively correlated concentration, OM, TN, NO3− linked concentration. increased Chao 1 Shannon indexes altered soil, due changes primarily influenced variations CEC, Cd, NH4+, phosphorous (AP) Potassium (AK) concentrations. Furthermore, abundant species (Pseudomonas) rare (Bacillus, Candidatus_Solibacter Streptomyces) up-regulated amendments, which might be favour immobilization.

Abstract Lime application (liming) has historically been used to ameliorate soil acidity in grasslands. Liming effectively improves pH, plant productivity, and physicochemical properties, but the long-term impact of control by liming on key microbial nitrogen (N)-cycling genes semi-natural grasslands is unknown. We investigated effect 65 years N-cycling processes limed plots Ossekampen grassland experiment Netherlands. These have not received any other fertilizers for years. Soil sampling nitrous oxide (N 2 O) emission measurements were conducted three times spring four summer, quantitative real-time PCR was performed determine absolute abundances genes, including ammonia-oxidation ( amoA -AOB, -AOA, -comammox), denitrification nirS , nirK nosZ ), nitrate ammonification nrfA N-fixation nifH ) genes. Long-term increased nitrifiers, denitrifiers, ammonifiers. N O emissions did differ significantly between treatments. Additionally, had a buffering that maintained population microbes against seasonal variations abundance. Our results indicate improving through potentially facilitates without increasing emissions.

Abstract Background Sewage sludge biochar has been widely used in agriculture for various purposes; however, knowledge about its residual effect on the soil microbial community is limited. Aims This study aimed to evaluate changes 5 years after application of sewage biochar. Methods Biochar was produced from obtained at a wastewater treatment pyrolyzed 300°C (Biochar300) and 500°C (Biochar500). Both treatments were applied corn fields two growing seasons (2014/2015; 2015/2016). not third (2016/2017) seventh (2020/2021) season assess effect. Soil samples collected harvesting 2020/2021 season, therefore fifth year subject effects The evaluated by accessing bacterial fungal groups using DNA techniques. Amplicon sequencing analysis performed with Illumina MiSeq 250 bp. Results At genus level, Lachnospira , Faecalibacterium Bacteroides Epulopiscium Parabacteroides affected Biochar500. Furthermore, upper levels taxonomy, this increased relative abundance classes Clostridiaceae Bacteroidia families Chaetomiaceae Aspergillaceae. Concerning relationship between chemical properties, phosphorus (P) calcium (Ca) significantly within community; ones P potential acidity (H + Al). Conclusions Even under years, altered plantation, especially concerning richness some groups. Biochar500 most responsive among treatments.
