Phosphorus-rich calcium-based bentonite (BM-PCB) was synthesized via a ball milling process and synergistically integrated with smooth vein (SV) to establish a coupled remediation system for Cd-contaminated soil. The combined application of BM-PCB and SV resulted in a 61.28% reduction in bioavailable Cd content, exhibiting 2.81- and 5.13-fold enhancements compared with those of BM-PCB (21.81%) and SV (11.94%) alone, respectively, confirming the existence of a strong synergistic passivation effect. BM-PCB enhanced the Cd enrichment capacity of SV by 2.83 times by promoting root development, subsequently increasing humic acid (HA) production by 33.33% by catalyzing the condensation reactions between phenolic compounds and amino acids following SV incorporation. The interaction between HA and BM-PCB enhanced Cd adsorption by improving the interlayer spacing, pore structure, functional group content, and charge characteristics of BM-PCB. Additionally, the beneficial microorganisms recruited by the coupling of BM-PCB and SV reduced Cd bioavailability as well as facilitated the decomposition and transformation of SV residues, thereby improving soil nutrients. This approach consequently increased the maize yield by 61.31% while concurrently reducing the Cd content in grains to comply with food safety standards. Life cycle assessment confirmed that the proposed BM-PCB+SV system represented a cost-effective and low-environmental-risk “three-in-one” strategy, simultaneously achieving Cd immobilization, soil fertility enhancement, and food security assurance.

Current management ofAgeratina adenophora, a highly invasive weed, relies on synthetic herbicides with environmental and resistance risks, necessitating eco-friendly alternatives. This study evaluated seven phenyl derivatives for phytotoxic activity againstA. adenophoravia in vitro bioassays. Methyl 4-hydroxyphenylacetate exhibited potent herbicidal efficacy, achieving 100% mortality in 2-month-old seedlings at 30 mM, 3-month-old seedlings at 100 mM, and wild adult/6-month-old plants at 200 mM within 48 h. At 250 mM, the compound reduced CO2assimilation by 113.6% and stomatal conductance by 92.2%, indicating severe photosynthetic and transpirational disruption via oxidative stress-mediated chloroplast degradation and stomatal dysfunction. Hormonal profiling revealed significant declines in IAA-ASP, GA1, TZeatin, and TZR, alongside elevated ABA levels, while GA3 remained stable. These hormonal shifts likely drive stomatal closure and metabolic collapse, culminating in plant death. This study provides the first evidence of methyl 4-hydroxyphenylacetate’s dual-action phytotoxicity—targeting both stomatal regulation and hormonal balance—positioning it as a sustainable biocontrol agent forA. adenophoraand potentially other invasive weeds.

Veterinary drugs are widely present in animal manure and manure-based fertilizers, making their safety for use as soil amendments still ambiguous. This study investigated the concentrations of 17 typical veterinary drugs in animal manure and manure-based fertilizers from Shandong Province using solid-phase extraction coupled with high-performance liquid chromatography–tandem mass spectrometry and assessed their environmental risks to soil organisms based on risk quotient values. The established method demonstrated robust performance, with drug recovery rates ranging from 72.9% to 109%. Tetracyclines were identified as the most prevalent contaminants, with mean concentrations of 1522 μg/kg in animal manure and 144 μg/kg in manure-based fertilizers. Drug concentrations in manure-based fertilizers were generally lower than those in animal manure. Livestock manure contained higher drug concentrations compared to poultry manure. Influenced by farming practices, drug concentrations were higher in beef cattle manure than in dairy cattle manure, and higher in broiler manure than in layer manure. Manure-based fertilizers primarily derived their drug content from chicken, cattle, and sheep manure. Tetracyclines in swine and sheep manure posed high risks to soil organisms, while those in beef cattle manure and dairy cattle manure posed medium risks. In contrast, most drugs in manure-based fertilizers exhibited low risks. Comprehensive analysis of both concentration levels and ecological risks indicates that manure-based fertilizers represent a more feasible option for soil amendment. This study provides a theoretical foundation for better understanding the feasibility of applying animal manure and manure-based fertilizers to agricultural land.

Chitosan (CS) films functionalized with cinnamaldehyde (CIN)-derived Schiff base and Fe 3+ coordination were developed for pH-responsive antimicrobial food packaging. The Schiff base-Fe 3+ crosslinking system enhanced tensile strength by 39.59% and reduced water vapor permeability by 11.25%, while imparting pH-triggered CIN release via acid-hydrolyzable imine bonds. Scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction, and thermogravimetric analysis confirmed uniform dispersion of CIN/Fe and improved crystallinity. The films demonstrated bactericidal activity against foodborne pathogens (89.52% for Escherichia coli ATCC 25922, 82.98% for Staphylococcus aureus ATCC 25923) combined with moderate 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) scavenging (37.41% at 30 min), suggesting primary application in antimicrobial packaging. In fruit preservation trials, strawberries and passion fruit coated with CS/CIN/Fe films showed 33.17% and 29.36% lower weight loss, respectively, extending shelf life by suppressing respiration-driven spoilage. Cytotoxicity (<0.21% hemolysis) and biocompatibility (>80% cell viability) validated safety. This work presents a sustainable strategy for intelligent packaging by integrating dynamic Schiff base-metal coordination, addressing both food waste and plastic pollution.

White pollution, excessive heavy metals, and fertilizer leaching have become key issues restricting the development of agriculture. In this work, we prepared multifunctional starch mulch film (SMF/MAP/FeS) by loading ferrous sulfide (FeS) and monoammonium phosphate (MAP) onto commercial starch mulch film using poly(vinyl alcohol) for bonding. The removal efficiencies of Pb(II)/Cr(VI) for SMF/MAP/FeS could reach 97% and 93% in the aqueous solution. The adsorption isotherm, thermodynamic, and kinetics studies indicated that the adsorption process was an endothermic multimolecular-layer chemisorption. The main removal mechanisms for Pb(II)/Cr(VI) of SMF/MAP/FeS were precipitation and redox reactions. In addition, SMF/MAP/FeS not only possessed great thermal insulation and moisturizing properties but also could realize the slow release of NH4+. Furthermore, the maximum release rate of NH4+ for SMF/MAP/FeS could reach 93.4% during Pb(II)/Cr(VI) removal. At the same time, SMF/MAP/FeS has a good degradability at 50 d. A pot experiment indicated that SMF/MAP/FeS had a detoxifying effect on the Pb(II)/Cr(VI)-contaminated soil to promote the growth of pakchoi. Therefore, this study not only solves the problem of plastic and heavy metal pollution but also realizes the slow release of nutrients.

Non-exchangeable potassium (NEK) is released from minerals by chemical extraction methods through dissolution and cation-exchange reactions. Assessing the contribution of these two processes to release budgets is important to predicting plant/mineral interactions and soil sustainability . Three NEK extraction methods, 1 M boiling nitric acid (HNO 3 ), 2 M hot hydrochloric acid (HCl) and 0.2 M sodium tetraphenylboron (NaTPB), were applied to investigate the mechanisms of NEK release from trioctahedral biotite and dioctahedral muscovite . Atomic force microscopy and X-ray diffraction were used to investigate the surface morphology and transformation of mica, respectively. NEK released from biotite and muscovite through cation-exchange reaction accounted for 87.88%, 85.93% and 83.23%, 78.31% of the total extracted K when extracted by boiling HNO 3 and hot HCl, respectively, with channel and elliptical dissolution pits on mica surface. NEK extracted by NaTPB was an almost complete cation-exchange reaction, and the extracted micas showed an obvious vermiculitic character and no dissolution features. Results showed the release of NEK from micas is essentially a cation-exchange reactions in both acid and salt solutions, indicating that NEK released through cation-exchange reaction but not via dissolution may make up the main soil K pool available to plant.

In an effort to enhance the efficiency of fertilizer use and minimize adverse environmental effects, a novel biomass-based, multifunctional controlled-release fertilizer (BMCF) was prepared to improve nutrient use efficiency and enhance crop production systems for more sustainable agriculture practices. The fertilizer design included natural attapulgite as a matrix, co-granulated ammonium zinc phosphate and urea as fertilizer core, cellulose acetate butyrate (CAB) as an inner coating, and a carboxymethyl chitosan-g-poly(acrylic acid)/attapulgite (CMCS-g-PAA/APT) superabsorbent composite as an outer coating. The effect of an APT matrix, CAB inner coating and superabsorbent composite outer coating on nutrient release rate was investigated. The influence of the BMCF on water-holding and water-retention capacity of soil samples was determined. The degradation behavior of the CMCS-g-PAA/APT outer coating in soil solution was evaluated. The experimental results indicated that the product prepared by a simple and economical method can effectively reduce N leaching loss and runoff, improve soil moisture retention capacity, and ameliorate soil acidity and alkalinity.

In the face of escalating global water scarcity, intensified by population growth and agricultural demands, there is an urgent need to improve water efficiency in greenhouse cultivation. The rapid development of atmospheric water harvesting technology offers us an opportunity to address this issue. Here a novel, solar-driven, scalable hygroscopic gel, termed TCP-Li, that demonstrates exceptional water uptake capacity (3.38 g water g sorbent −1 ) and rapid solar thermal water release was reported. As a proof-of-concept application, we utilize this material in a transpiration and evaporation adsorption device (TEAD), which leverages the properties of TCP-Li to efficiently harvest water vapour from plant transpiration and soil evaporation. TEAD operates passively, absorbing moisture at high relative humidity during the night and releasing water for irrigation during the day using natural sunlight. Greenhouse experiments confirmed the efficacy of TEAD in ensuring normal plant growth while providing additional irrigation water (87.1 g per plant and 1,890.6 g m −2 ), thereby achieving an average water-saving effect of 44.9%. This study introduces a groundbreaking solution aimed at enhancing water efficiency in greenhouse cultivation, offering substantial potential for commercial and large-scale agricultural applications and significantly contributing to mitigating the global water crisis and optimizing water use in modern agriculture.

The development of efficient biobased controlled-release fertilizers has captured much research attention because of the environmental concerns and food scarcity problems. In this work, a biomimetic superhydrophobic biobased polyurethane-coated fertilizer (SBPF) was successfully fabricated by increasing surface roughness and reducing surface energy of polyurethane (PU) coating. The green PU coating was synthesized from low-cost, biodegradable, and renewable cottonseed oil. The nutrient release longevity of SBPF revealed 2-fold enhancement compared with the normal biobased PU-coated fertilizer (BPF). The significant improvement of nutrient release characteristics can be attributed to the atmosphere “outerwear” which ensured the nonwetting contact of water with superhydrophobic surfaces in gas state instead of in liquid state. The new concept introduced in this study can inform the development of the next generation of biobased controlled release fertilizers.

Although bio-materials for controlled-release fertilizers (CRFs) have been developed rapidly because of their low-cost and green and sustainable properties, the release characteristics of these CRFs still face problems because the coating is often hydrophilic with many micro-holes. In this paper, a novel coating material was developed to coat fertilizers using bio-based polyurethane (BPU) derived from liquefied wheat straw (LWS). Organosilicon (OS) and nano-silica (NS) were also used to modify the BPU to increase the nanoscale surface roughness and reduce the surface energy, and thus to make it superhydrophobic. The nutrient release characteristics of the superhydrophobic BPU coated fertilizer (SBPCF) were greatly enhanced, compared with the unmodified BPU coated fertilizer (BPCF). This was because the nanoscale surface roughness of the SBPCF prevented water from contacting the coating material. In addition, the nanoparticles on the SBPCF surface also block the micro-holes on the coating and thus reduced the entrance of water. The results suggest that the new coating technology can create a superhydrophobic surface on CRFs and thus improve their controlled-release characteristics.

Nearly 1.3 billion tons of food are discarded annually in the production process. In this study, a novel slow-release nitrogen fertilizer with water absorbency was developed using leftover rice and crosslinking methods. Urea was incorporated as the nitrogen source in a leftover rice-g-poly(acrylic acid)/montmorillonite (LR-g-PAA/MMT) network, and then the leftover rice-g-poly(acrylic acid)/montmorillonite/Urea (LR-g-PAA/MMT/Urea) retained in the soil, and used as the loss control agent for water and nutrients. Variables including concentrations of acrylic acid , montmorillonite , N,N´-methylenebis acrylamide (MBA), and potassium persulfate (KPS) were investigated. Samples were with a water absorbency of 102.6 g/g in distilled water and 25.1 g/g in 1.0 wt% NaCl solution under optimized conditions. Swelling measurements and water-retention indicated that higher-covalent cations would aggregate the hydrogels and decrease swelling. Investigating leaching behavior showed that these samples have the potential to carry the necessary nitrogen (N). The results demonstrated that the LR-g-PAA/MMT/Urea had a low leaching losses of N (19.7%) compared with pure urea (52.3%). Therefore, the developed fertilizer may be widely applicable in agriculture and horticulture , and could provide a new platform for reusing leftover rice.

Climate change is affecting agricultural production and other aspects of life but only limited number of studies took interest in characterizing and projecting climate and its impact on crop production at local level. The threat to agricultural sector is more serious in Ethiopia, where climate is influenced by diverse topography and varying landscape features. This study was conducted in Welmera area to model the impacts of climate change on production of two faba bean ( Vicia faba L.) varieties (Tums and Gora). Historical climate and crop yield data were obtained from the National Meteorological Agency of Ethiopia and Holeta Agricultural Research Center, respectively. Future climate data were downscaled by an average ensemble of four GCMs (BSS-CSM1-1, HadGEM2-ES, MIROC-ESM, NorESM1-M) in near- and mid-century (2030s and 2050s) under both RCP 4.5 and RCP 8.5. Rainfall by near-century will increase by up to 50% depending on the concentration pathway considered compared to the baseline period (1988–2017). The projected average rainfall total of belg season (FMAM) will increase by 88.17% under RCP 4.5 scenario and 95.38% under RCP 8.5 scenario in near-century. The future projection revealed that the highest mean monthly rainfall and temperature changes will occur in July (147.3 mm/month) and August (0.24 °C/month) under RCP8.5. However, in August and September mean monthly rainfall will decrease dramatically by 50.85 % and 31.05% from 2020 to 2079 under RCP 8.5 and RCP 4.5, respectively. The yield of Tumsa variety will decrease by up to 24.19% under RCP8.5 in mid-century. Gora variety will see an increase of yield by 18.24% under RCP 4.5 in mid-century and 28.03% under RCP 8.5 in near-century. Overall, the area will experience an increase and a decrease in faba bean yield for both varieties in the upcoming decades in the study area. Performance evaluation of the models showed that they were able to predict future yield faba bean varieties in the area with acceptable accuracy. Inconsistency of future climate variables and impact on fababean production underscores the need to develop location-specific adaptation strategies. Further studies that consider wider area could be necessary to better understand the impact of future climate on faba bean production in the study area and similar agroecologies in the country.
