Heavy metal contamination is currently a major environmental concern, as most agricultural land being polluted from municipal discharge. Among various other pollutants, cadmium (Cd), one of the harmful heavy metals, enters into food chain through irrigation crops with an industrial effluent. In present study, pot experiment was designed to assess effect different nitrogen (N)-fertilizer forms in phytoremediation Cd Solanum nigrum L. Two types N fertilizers (NH4NO3 and urea) were applied soil ratios (0:0, 100:0, 0:100, 50:50 NH4NO3 urea, individually) along levels (0, 25, 50 mg kg−1). The plants harvested 70 days after sowing seeds pots. Cadmium significantly inhibited growth leaves roots S. plants. also induced oxidative stress; however, application N-fertilizers increased plant biomass by inhibiting stress enhancing antioxidants’ enzymatic activities. greatest observed urea-treated compared NH4NO3-treated addition, urea-fed accumulated higher concentrations than NH4NO3-fed It concluded that urea helpful for better under stress. Thus, optimum concentration might be effective metals nigrum.

Stoichiometric control of input substrate (glucose) and native soil organic C (SOC) mineralization was assessed by performing a manipulation experiment based on N or P fertilization in paddy soil. Glucose increased with nutrient addition up to 11.6% combined application compared that without addition. During 100 days incubation, approximately 4.5% SOC mineralized stimulated glucose exponentially dissolved (DOC):NH4+-N, DOC:Olsen P, microbial biomass (MB)C:MBN ratios. The relative abundances Clostridia β-Proteobacteria (r-strategists) were NP at the beginning experiment, while Acidobacteria (K-strategists) enhanced exhaustion available resource end incubation. bacteria abundance diversity negatively related DOC:NH4+-N which had direct positive effects (+ 0.63) mineralization. Combined decreased network density bacterial community. Moreover, significantly negative associations among taxa, suggested competition for nutrients alleviated. keystone species showed significant correlations soils application, revealing microbes their activity mining limited from matter. Hence, shifted community composition interactions acquire necessary elements increasing maintain C:N:P stoichiometric balance response changes stoichiometry.

Biogenic nitrous oxide (N2O) from nitrification and denitrification in agricultural soils is a major source of N2O the atmosphere, its flux changes significantly with soil moisture condition. However, quantitative relationship between production different pathways (i.e., vs. denitrification) content remains elusive, limiting our ability predicting future emissions under changing environment. This study quantified rates various conditions using laboratory incubation combined literature synthesis. 15N labeling approach was used to differentiate eight contents ranging 40 120% water-filled pore space (WFPS) study, while 80 groups data 17 studies across global were collected Results showed that as increased, first increased then decreased, peak occurring 95% WFPS. By contrast, dominant pathway switched 60 70% Furthermore, synthetic elucidated driver controlling relative contributions production, NH4 + NO3 - concentrations mainly determined each pathway. The treatments broad narrow gradient required capture comprehensive response rate change, essential for accurately emission climate change scenarios.

As an exogenous carbon input, microplastics (MPs), especially biodegradable MPs, may significantly disrupt soil microbial communities and element cycling (CNPS cycling), but few studies have focused on this. Here, we assessing the effects of conventional low-density polyethylene (LDPE), polybutylene adipate terephthalate (PBAT), polylactic acid (PLA) MPs rhizosphere CNPS in a soil-soybean system. The results showed that PBAT-MPs PLA-MPs were more detrimental to soybean growth than LDPE-MPs, resulting reduction shoot nitrogen (14.05% 11.84%) biomass (33.80% 28.09%) at podding stage.

Abstract Flooded paddy soils after rewetting dry accompanied by extensive nitrogen fertilizer input are important anthropogenic N 2 O emitters due to the denitrification process. Owing multiple complex denitrifying sources, however, extent which biotic (fungal or bacterial) and abiotic (chemical) contribute total emissions remains largely unquantified. Here we sampled across eight provinces where most of flooded were in China explore microbial potentials decipher dynamics. isotopocules site preference (δ 15 SP ) analyses found that soils, fungi‐mediated was largest contributor (51%–63%); while bacterial chemical denitrifications contributed 12%–31% 12%–28% emissions, respectively. Further, using labeling, a significant spatial heterogeneity performance observed among these soils. As indicated variance partitioning regression analyses, this mainly determined soil properties (especially organic carbon nitrogen) rather than communities. Our findings provide insights into establishment predictive models future emission from global considering both contributions.
