Recycling nutrients is essential for closing nutrient loops within a circular economy. Using locally available resources such as human excreta to produce bio-based recycling fertilizers can substitute mineral fertilizers and thereby promote environmentally friendly food production. To better understand the fertilizer potential and nitrogen value of human excreta, three novel and safe recycling products were evaluated in a field experiment. Two nitrified urine fertilizers (NUFs) and one fecal compost were applied alone or in combination, and compared against the commercial organic fertilizer vinasse. In addition, the uptake of pharmaceuticals was assessed for treatments with compost application. White cabbage (Brassica oleracea var. capitata f. alba) was cultivated in plots in three different soil types (sand, loam or silt) treated with the fertilizers according to plant needs and mineral soil nitrogen content. The two NUFs resulted in marketable yields similar to those of vinasse in all soil types. Combining fecal compost with a NUF led to increased marketable yield compared to compost alone. The highest yield was recorded from the sandy soil, where vinasse and NUF treatments led to comparable yields, as expected in organic productions systems (up to 72 t ha−1). The cabbage yield and total aboveground fresh biomass followed the following trend in all soils: NUFs ∼ vinasse ≥ compost + NUF ≥ compost. Nitrogen uptake in the cabbage heads and total biomass was significantly higher in sand (69.5–144 kg ha−1) than loam (71.4–95.8 kg ha−1). All compost treatments alleviated the effect of soil type and resulted in comparable nitrogen uptake and yield in all soil types. Plant uptake of pharmaceuticals (Carbamazepin) was higher in sand than in loam, and concentration in the edible part was lower than in the outer leaves. In conclusion, NUF alone appears to be a promising successful fertilizer substitute in horticultural food production. The combined application of NUF and compost led to slightly lower crop yields, but may increase soil carbon content in the long term, promoting climate-friendly food production.

The transmission and transformation patterns of antibiotic resistance genes (ARGs) in the soil-onion continuum under the application of organic fertilizers in actual agricultural cultivation are still unknown. This study systematically analyzed the occurrence characteristics of ARGs in soil and onion (roots and bulbs) under the application of organic fertilizer from livestock manure, and revealed the response mechanism of phenolic metabolites in roots. The results showed that fertilization promoted the enrichment of ARGs in the soil and onions. The abundance of ARGs in the bulbs of the pig manure and sheep manure treatment groups was 4 times and 2 times as high as that in the unfertilized group, respectively. In comparison to the bulbs, a higher abundance of ARGs was observed in the roots of onions. The 11 ARGs, including high-risk variants such as tetX and mexE , were detected co-occurring in both onion tissues and the surrounding soil. Fertilization treatment significantly changed the community composition of ARGs-related host bacteria in onion tissues. Livestock manure-based organic fertilizers elevated the potential exposure risk of ARGs in bulbs by more than 20%. Five strains of multidrug-resistant endophytic bacteria (including Streptomyces and Pseudomonas ) were isolated from the main edible parts of onion bulbs. It is worth noting that this study found that kaempferol (35-140 μg/L) and p-coumaric acid (2.5-10 μg/L) significantly enhanced the conjugation and transfer of the RP4 plasmid in the onion endophytes ( Bacillus sp. and Paenibacillus sp.) and soil microbial communities. Root exudates were the predominant factors regulating the transmission of ARGs in the soil-onion system.

Humification processes of phenolic pollutants may play a profound role in environment purification and plant growth. However, little literature is performed to explore exoenzyme-driven humification to polymerize 17 β -estradiol (E2) and humic constituents (HCs), and the effects of their polymeric precipitates on plant growth are usually overlooked. Herein, E2 conversion and radish ( Raphanus sativus L.) growth were systematically investigated under humification mediated by extracellular laccase (EL) of Trametes versicolor . Results disclosed that EL-assisted humification achieved a wonderful E2 conversion efficiency (>99%) within 2-h, but the presence of HCs such as humic acid (HA), vanillic acid (VA), and ferulic acid (FA) impeded E2 elimination significantly. Compared with HC-free, the kinetics constants declined by 2.84-, 5.72-, and 5.22-fold with HA, VA, and FA present, respectively. Intriguingly, three close-knit self/cross-linked precipitates ( i.e. , E2-HA, E2-VA, and E2-FA hybrid precipitates) in dark gray, dark brown, and deep yellow were created after a continuous humification by phenolic radical-initiated polymerization mechanisms. The formation of these humified precipitates was extremely effective on circumventing phytotoxicity caused by monomeric E2, VA, or FA. Furthermore, they acted as humic-like organic fertilizers , accelerating seed germination, root elongation, and enhancing NaCl-tolerance of radish through the combination of oxygen-contained functional components and auxin structural analogues with unstable and stubborn carbon skeletons. This is the first study reporting the pollution purification and plant growth promotion in EL-activated humification. Our findings frame valuable perspectives regarding the natural detoxification and carbon sequestration of phenolic pollutants and the application of their polymeric precipitates in global crop production.

Phthalate acid esters (PAEs) are ubiquitous pollutants in agricultural soils . Application of bioorganic fertilizer (BOF) containing beneficial microbes represents a promising approach to improve the yield and quality of crops grown in contaminated soils. In the present study, a novel multifunctional bioorganic fertilizer N-BOF was developed by using compost of sewage sludge and agricultural waste and inoculating with PAEs-degrading B. megaterium YJB3 and phosphate solubilizing B. megaterium YLYP1. Its feasibility of improving the yield and quality of vegetable grown in PAEs (including DBP and DEHP) contaminated soil was evaluated by pot experiments. The N-BOF could effectively promote plant growth, with biomass increasing by 4–66.9% and 19–110% compared to chemical (CF) and no fertilizer (CK), respectively. The concentrations of DBP and DEHP in shoots of chemically fertilised vegetable ranged 1.23–3.12 mg/kg (dry weight, DW) and 1.63–3.89 mg/kg (DW), respectively. Their concentrations were significantly decreased ( p < 0.05) when N-BOF was applied (1%, 2%, 5% amendment), especially at higher application rate ranging 0.11–0.3 mg/kg (DW) and 0.16–0.32 mg/kg (DW), respectively. Meanwhile, vegetable quality attributes were also significantly improved when 2% N-BOF was applied, with increase in the contents of vitamin C , vitamin B1, total protein, and starch, and decrease in the contents of nitrite and nitrate. In this case, the human health risk from consumption of the vegetable grown in PAEs-contaminated soil could be significantly reduced. Thus, our study is expected to provide an efficient way of high-value utilization of organic substrates by producing low-cost but high quality N-BOF. Future studies on the effects of N-BOF in terms of fertilizer regimes on yield and quality of the vegetable are needed, and further field studies for assessing the long-term efficacy and reliability of this promising N-BOF are also warranted.

The present study evaluated the efficiency of pre-selected composite amendments (CA-1: biochar-lime-sepiolite-zeolite and CA-2: manure-lime-sepiolite) for immobilization and sorption of Cd and Pb in field and batch sorption experiments. The field experiment was performed in a co-contaminated clay purple soil (stagnic anthrosols). Along with a control experiment (T1), CA-1 and CA-2 were tested at different rates including 750, 1500, 3000 and 6000 kg ha −1 by growing wheat as the test crop. The obtained results revealed that the highest dose of both composites (T5: 6000 kg ha −1 and T9: 6000 kg ha −1 ) increased the soil pH to 6.85 and 6.81, respectively as compared to the control (5.63). DTPA-extractable Cd and Pb contents decreased with composite treatments (T7 and T4) at harvest stage samples. Metal fractionation depicted that application of amendments decreased the exchangeable fraction at harvesting stage. Application of CA-2 and CA-1 (3000 kg ha −1 ) significantly increased the plant biomass (by 28% and 24%, respectively) and grain yield (by 26% and 22%, respectively) of wheat. Furthermore, batch sorption experiment results revealed that Langmuir adsorption model better fitted the sorption results with R 2 values ranging between 0.99 and 0.91 for Cd and Pb, respectively. CA-1 and CA-2 exhibited the maximum adsorption capacity for Cd with no significant difference among treatments but Pb adsorption capacity was highest in CA-1 followed by CA-2 and control. The results of our experiments revealed that the application of organics combined with inorganic materials enhanced Cd and Pb immobilization and sorption, consequently reducing metals availability in laboratory and field conditions. Moreover, for field trials, application of the composite amendments at 3000 kg ha −1 emerged as the suitable treatment for tested wheat-grown area.

The analysis of veterinary drugs in organic fertilizers is crucial for an assessment of potential risks to soil microbial communities and human health. We develop a robust and sensitive method to quantitatively determine 19 veterinary drugs (amantadine, sulfonamides and fluoroquinolones) in organic fertilizers. The method involved a simple solid-liquid extraction step using the combination of acetonitrile and McIlvaine buffer as extraction solvent, followed by cleanup with a solid-phase extraction cartridge containing polymeric mixed-mode anion-exchange sorbents. Ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC–MS/MS) was used to separate and detect target analytes. We particularly focused on the optimization of sample clean-up step: different diluents and dilution factors were tested. The developed method was validated in terms of linearity, recovery, precision, sensitivity and specificity. The recoveries of all the drugs ranged from 70.9% to 112.7% at three concentration levels, with the intra-day and inter-day relative standard deviation lower than 15.7%. The limits of quantification were between 1.0 and 10.0 μg/kg for all the drugs. Matrix effect was minimized by matrix-matched calibration curves. The analytical method was successfully applied for the survey of veterinary drugs contamination in 20 compost samples. The results indicated that fluoroquinolones had higher incidence rate and mean concentration levels ranging from 31.9 to 308.7 μg/kg compared with other drugs. We expect the method will provide the basis for risk assessment of veterinary drugs in organic fertilizers.

Three organic fertilizers made of different animal and plant waste materials (BOFs) were evaluated for their effects on the production of antibacterial volatile organic compounds (VOCs) by two Bacillus amyloliquefaciens strains SQR-9 and T-5 against the tomato wilt pathogen Ralstonia solanacearum (RS). Both strains could produce VOCs that inhibited the growth and virulence traits of RS; however, in the presence of BOFs, the production of antibacterial VOCs was significantly increased. The maximum inhibition of growth and virulence traits of RS by VOCs of T-5 and SQR-9 was determined at 1.5% BOF2 and 2% BOF3, respectively. In case of strain T-5, 2-nonanone, nonanal, xylene, benzothiazole, and butylated hydroxy toluene and in case of strain SQR-9, 2-nonanone, nonanal, xylene and 2-undecanone were the main antibacterial VOCs whose production was increased in the presence of BOFs. The results of this study reveal another significance of using organic fertilizers to improve the antagonistic activity of biocontrol agents against phytopathogens.

Steroid estrogens (SEs) play a significant role as endocrine-disrupting substances, and one of their major sources is animal manure. However, there is limited information available regarding the loss of SEs in farmland soil after the application of commercial composted animal manure or fertilizers. To address this gap, our study aimed to simulate rainfall and flood irrigation scenarios and investigate the loss characteristics of SEs, as well as Chemical Oxygen Demand (COD), Total Nitrogen (TN), and Total Phosphorus (TP) in runoff from soil–manure mixtures. The results demonstrated that the loss concentrations of SEs (73.1 ng/L of the mean E2β active equivalent factor) presented a potential environmental risk. Additionally, substituting composted manure with commercial organic fertilizers lead to a significant reduction in TP (maximum 56%) and TN (maximum 24%) loss. Consequently, the application of commercial organic fertilizers offers considerable advantages in maintaining nitrogen and phosphorus fertilization efficiency while controlling SEs loss. Furthermore, our study explored the synergistic pollution mechanism among these pollutants and observed significant correlations between SEs and TN, TP, and COD loss concentrations, indicating the simultaneous occurrence and migration of these pollutants in agricultural non-point source pollution. These results provide valuable insights into the environmental risk associated with SEs from agricultural non-point sources.

The volatile organic compounds (VOCs) produced by antagonistic microbes have great antifungal potential against soil-borne fungal pathogens. The VOCs produced by Paenibacillus polymyxa strain WR-2 in the presence of root exudates and organic fertilizer were identified and their effects on the growth and spore germination of Fusarium oxysporum f. sp. niveum were evaluated. The VOCs produced by WR-2 inhibited the growth of F. oxysporum by 38%, 36% and 40% in agar medium, sterilized soil and natural soil, respectively. This inhibitory effect was increased to 60%, 58% and 64% with the addition of organic fertilizer in agar medium, sterilized soil and natural soil, respectively. The addition of root exudates did not affect the production of antifungal VOCs by WR-2. The VOCs produced by WR-2 completely inhibited the germination of F. oxysporum spores. Out of 42 identified VOCs, seven VOCs; benzothiazole, benzaldehyde, undecanal, dodecanal, hexadecanal, 2-tridecanone and phenol were found to inhibit the growth of F. oxysporum . The results of these experiments suggest another significance of using organic fertilizer as a carrier material with the biocontrol agents to control soil-borne fungal pathogens.

To test whether manure amendment in soil reduces plant uptake of persistent organic pollutants, carrot ( Daucus carota L. ) was used as a model plant and 2,2′,4,4′-tetrabrominated diphenyl ether (BDE-47) was selected as a model persistent organic pollutant to conduct a pot experiment with contaminated soil amended by composted pig manure. The results showed that the concentration and bioconcentration factors (BCFs) of BDE-47 in the edible part of carrot significantly decreased from 229.7 ± 28.2 to 43.4 ± 20.4 ng g −1 and from 1.86 ± 0.5 to 0.15 ± 0.03, respectively, with increasing composted pig manure dose from 0 to 4%. Organic matter (OM) derived from composted pig manure played a dominant role in reducing persistent organic pollutant bioavailability in soil. Composted pig manure amendment and carrot cultivation jointly altered the bacterial community composition in soil, especially the rhizosphere. Rhizodegradation of BDE-47 was enhanced from 8.6 to 28.5% with increasing composted pig manure dose from 0 to 4%, corresponding to increased soil microbe diversity and polybrominated diphenyl ether-degrading bacteria ( Sphingomonas , etc.) abundance in the rhizosphere. This study is the first, to the best of our knowledge, to provide an effective agronomic strategy of manure amendment to reduce plant uptake and simultaneously enhance rhizodegradation of persistent organic pollutants in soil, and thus potentially reduce human health risks through dietary intake.

Phthalates (PAEs) are emerging organic pollutants that threaten agroecosystems by diminishing agricultural productivity and posing risks to human health. However, traditional organic fertilizers have limited effectiveness in remediating PAE-contaminated soils, while bacterial remediation often lacks stability in heterogeneous soil environments. Here, a novel bio-organic fertilizer (N-BOF) containing the PAE-degrading Bacillus megaterium YJB3 was evaluated in pot experiments for its effectiveness in remediating PAEs-contaminated soils. Results revealed that N-BOF significantly reduced PAE concentrations in soil. At PAE levels of 20 and 100 mg/kg, N-BOF reduced DBP and DEHP concentrations by over 96 %, with a maximum reduction of 99.39 %. Additionally, N-BOF significantly enhanced soil physicochemical properties, increasing organic matter (OM), total organic carbon (TOC), cation exchange capacity (CEC), nutrient availability, and pH. N-BOF also improved the soil bacterial community, enhancing diversity, degradation capacities, and the abundance of aromatic compound-degrading bacteria. Ecological risk assessments demonstrated that N-BOF effectively mitigated PAE contamination risks, reducing the risk quotients (RQ) of DBP and DEHP to safe levels. This study provides practical strategies and theoretical insights for the sustainable remediation of PAE-contaminated soils, utilizing composting to simultaneously improve soil fertility and effectively eliminate PAEs.

The ecotoxic endocrine-disrupting chemical di-(2-ethylhexyl) phthalate (DEHP) is ubiquitous in agricultural soil, posing a serious threat to human health. Here, we report efficient soil-borne DEHP degradation and plant growth promotion by a microbial organic fertilizer GK-PPB prepared by combining a recycled garden waste-kitchen waste compost product with ternary compound microbial agent PPB-MA, composed of Penicillium oxalic MB08F, Pseudomonas simiae MB751, and Bacillus tequilensis MB05B. The combination of MB08F and MB751 provided synergistic phosphorus solubilization , and MB05B enhanced the DEHP degradation capacity of MB08F via bioemulsification. Under optimal conditions (25.70 °C and pH 7.62), PPB-MA achieved a 96.81 % degradation percentage for 1000 mg L −1 DEHP within 5 days. The degradation curve followed first-order kinetics with a half-life of 18.24 to 24.76 h. A complete mineralization pathway was constructed after identifying the degradation intermediates of 2 H-labeled DEHP. Evaluation in Caenorhabditis elegans N2 showed that PPB-MA eliminated the ecological toxicity of DEHP. A pakchoi ( Brassica chinensis L.) pot experiment demonstrated that GK-PPB promoted phosphorus solubilization and plant growth, reduced soil DEHP residue, and decreased DEHP accumulation in pakchoi, suggesting its potential practical utility in environmentally responsible and safe cultivation of vegetables.
