Lodging is a major constraint limiting oil flax production efficiency in northern China.Crop lodging susceptibility is closely related to stem lignin content,and the regulatory mechanisms by which nitrogen and potassium fertilization interactively influence lignin biosynthesis in oil flax stems require further investigation.Therefore,this study aimed to enhance lodging resistance and increase grain yield in oil flax.We examined the interactive effects of different nitrogen (75,150,and 225 kg N ha–1) and potassium (60 and 90 kg K2O ha–1) fertilizer rates on lignin metabolism,lodging resistance,and grain yield during the 2022 and 2023 growing seasons.Results indicated that nitrogen and potassium fertilizer levels and their interactions promoted lignin accumulation,improved lodging resistance,and increased grain yield.Compared to the control (CK),the75–150 kg N ha–1 combined with 60 kg K2O ha–1 treatments significantly enhanced the activities of key lignin-synthesizing enzymes (tyrosine ammonia-lyase (TAL),phenylalanine ammonia-lyase (PAL),cinnamyl alcohol dehydrogenase (CAD),and peroxidase (POD)) and upregulated the expression of 4CL1 and F5H3 genes,leading to a 29.63–43.30%increase in lignin content,improved stem bending strength and lodging resistance index,and a 23.27–32.34%increase in grain yield.Correlation analysis revealed that nitrogen and potassium fertilizers positively regulated enzyme activities and gene expression related to lignin biosynthesis,thereby facilitating lignin accumulation and enhancing stem mechanical strength and lodging resistance.Positive correlations were observed among lignin-related enzyme activities,gene expression,lodging resistance traits,and grain yield.In summary,the application of 75–150 kg N ha–1 in conjunction with 60 kg K2O ha–1promoted lignin biosynthesis and accumulation,enhanced lodging resistance,and increased grain yield in oil flax grown in the dryland farming region of central Gansu,China.Furthermore,this treatment provides a technical basis for cultivating stress-tolerant and high-yield oil flax in arid regions. 展开更多

Nitrogen(N)fertilizer deep placement has been widely adopted to improve nutrient use efficiency and maize yield in the semiarid regions of northwest China.However,previous studies on optimal fertilization depth have yielded inconsistent results across climate conditions,limiting its practical application.This study aims to determine the site-specific optimal N fertilization depth for spring maize by evaluating photosynthetic growth dynamics,yield formation,and N utilization in two contrasting semiarid regions.A two-year(2021-2022)field experiment was conducted in Dingxi(semiarid drought-prone region)and Jingning(typical semiarid region),with five fertilization depths:0 cm(D0),5 cm(D5),15 cm(D15),25 cm(D25),and 35 cm(D35).A 15N-labeled urea micro-plot experiment was additionally conducted to trace N fate.The results demonstrated that,compared with the conventional N placement treatment(D15),D25increased soil total N storage,net photosynthetic rate,root bleeding rate,and the concentrations of NO3--N and NH4+-N in the bleeding sap.PLS-PM analysis revealed that fertilization depths that are excessively deep(D35)or shallow(D0,D5,D15)adversely affect the photosynthetic parameters and root activity of maize,thereby inhibiting dry matter accumulation and grain N uptake,which ultimately reduces both yield and nitrogen use efficiency(NUE).Compared with D15,D25 increased grain yield,and NUE by8.79% and 33.19% at Dingxi,and by 7.11%and 11.25% at Jingning.15N isotope tracing revealed that D25 improved maize N uptake while reducing residual soil N and N losses.Regression analysis indicates regional differences in the optimal N application depth.To achieve the lowest N residual loss and the highest yield and NUE,Dingxi(23.49 cm)requires a deeper fertilization depth compared to Jingning(21.64 cm).In conclusion,N fertilizer deep placement is a viable strategy for enhancing agricultural productivity and efficiency in semiarid regions,but the appropriate depth should be selected based on local conditions. 展开更多

To clarify the remediation effect of microbial inoculant fertilizer on cadmium(Cd)pollution following the application of pig manure organic fertilizer,a field experiment was conducted.No fertilization(CK1)and conventional fertilization(CK2)were used as controls.The treatments included conventional fertilization+pig manure organic fertilizer(PM,2800 kg/hm2)and four levels of microbial inoculant fertilizer(7.5,15,22.5,30 L/hm2)combined with the PM treatment.The study compared the effects of different treatments on rice economic traits,yield,Cd content in grains and plants,soil available Cd,total Cd,soil pH,and soil enzyme activities.The results showed that conventional fertilization+pig manure organic fertilizer significantly increased the effective panicle number per hectare and yield of rice.However,it concurrently led to a significant increase in rice grain Cd content,soil available Cd,and total Cd by 26.08%,13.35%,and 16.67%,respectively.Membership function analysis for comprehensive evaluation of economic traits and quality indicated that the treatment with 70%chemical fertilizer+pig manure organic fertilizer received the highest score.Compared with the application of pig manure organic fertilizer alone,the combined application of microbial inoculant fertilizer and pig manure organic fertilizer reduced rice grain Cd content,plant Cd content,total soil Cd,and available Cd by 20.50%~28.42%,4.48%~12.54%,4.98%~10.25%,and 43.28%~49.59%,respectively.Further analysis revealed that the combined application increased soil pH by 0.10~0.24 units,and enhanced the activities of soil sucrase,catalase,urease,and alkaline phosphatase by 7.49%~17.85%,4.19%~10.18%,0.39%~15.69%,and 16.35%~48.08%,respectively.Based on the comprehensive score from principal component analysis,the treatment with microbial inoculant fertilizer at 15 L/hm2+pig manure organic fertilizer+70%chemical fertilizer achieved the highest score.Considering the production economic value,the fertilization model of microbial inoculant fertilizer at 15 L/hm2+pig manure organic fertilizer+70%chemical fertilizer is recommended for application and promotion in local production. 展开更多

Farmers in China often use nitrogen(N)fertilizers to ensure adequate crop growth.However,inappropriate applications have increased the risk of environmental pollution,lowered maize yields,and reduced profits for farmers.Proper N fertilizer management is crucial for improving yield and nitrogen use efficiency(NUE).This study conducted a three-year experiment involving nine N treatments(0,45,90,135,180,225,270,315,and 360 kg ha-1)on a field under nitrogen fertilizer precision management(NFPM)in Northeast China.The results were compared with studies published within the past decade that analyzed yield and dry matter(DM)content under two management practices in Northeast China:conventional nitrogen fertilization management(CNFM)and water-saving fertilization management(WSFM).The findings reveal that maize yield increases with rising N application rates up to 270 kg ha-1,after which yield decreases.The kernel number(KN)and kernel weight(KW)of maize grown under NFPM were 13.7 and 14.7%higher than those grown under WSFM,respectively.Furthermore,they surpassed crops grown under CNFM by 38.4 and 21.2%,respectively.The maximum total yield of the NFPM treatment was 41.8 and 78.8%higher than under WSFM and CNFM,respectively.In addition,compared with CNFM and WSFM,NFPM significantly increased NUE across the various N-level treatments.Optimizing nitrogen management can help farmers to achieve higher yields and promote sustainable agricultural development. 展开更多

Single-time fertilization(STF)with controlled release blended fertilizer(CRBF)improves grain yield and nitrogen use efficiency(NUE)in rice production.However,the impact of soil nitrogen(N)distribution and root growth on rice yield and NUE under STF with CRBF remains unclear.Here,a two-year field experiment investigated the effects of two fertilizer types(normal urea(U)and CRBF)and two single-time fertilization methods(broadcast and side-deep fertilization)on the soil N distribution,plant N uptake,root characteristics,grain yield,and NUE.The results showed that CRBF under STF increased the averages of plant dry matter accumulation,N uptake,grain yield,nitrogen recovery efficiency(NRE),and nitrogen agronomic efficiency(NAE)by 8.29,21.85,10.57,79.28,and 74.8%compared to the other treatments,respectively.Side-deep fertilization with CRBF further increased NUE by 12.78%compared to broadcast.Moreover,CRBF under STF increased the leaf SPAD value and glutamine synthetase(GS)/glutamine oxoglutarate aminotransferase(GOGAT)activity by 5.93 and 25.58%,respectively.CRBF under STF increased the soil inorganic N concentration and showed a“rising early and stabilizing later”pattern.In addition,CRBF under STF improved rice root growth and increased the averages of root biomass,total root number,root average diameter,total root length,total root surface area,and total root volume by 28.30,28.56,18.64,13.38,35.26,and 37.06%,respectively,at the tillering and heading stages.Partial least squares path modeling indicated that CRBF under STF increased the soil inorganic N concentration which improved root morphology,thereby increasing N uptake and improving the rice yield and NUE.Taken together,our findings show that CRBF with single-time fertilization is the preferred N fertilizer strategy for achieving high yield and efficiency in rice,and that side-deep fertilization is the optimal fertilization method. 展开更多

The potential of hydroxyapatite(HA)nanoparticles as an alternative fertilizer has been extensively explored to mitigate the negative effects of conventional fertilizers on soil health.However,their low solubility in soil remains a significant challenge as this property reduces their efficiency for controlled nutrient delivery.To address this challenge,organic-inorganic nanocomposites,particularly HA-biopolymer-based nanofertilizers,have been proposed.These biocomposites combine the nutrient-rich feature of HA with the improved solubility and controlled-release ability provided by biopolymers,while also enhancing soil interaction to ensure more efficient and sustainable fertilization.The polymeric phase plays a key role in nutrient solubilization kinetics by facilitating microbial release,minimizing the need for frequent application,and reducing the toxicity to plants,which altogether reduces the overall environmental implications of fertilizer application.Despite recent advances,several key scientific gaps remain unaddressed,including the optimization of synthesis methods,the role of polymer composition in nutrient release kinetics,and the long-term effects of these nanofertilizers on soil health and plant productivity.This review provides a comprehensive analysis of the recent progress and prospects for HA-based nanofertilizers,emphasizing synthesis techniques,structural properties,and performance in soil environments.Additionally,it highlights the need for tailored approaches to optimize nutrient release profiles,ensuring sustained nutrient availability,reduced environmental impact,and enhanced agricultural productivity.By identifying these knowledge gaps,this review aims to guide future research toward the design of next-generation HA-biopolymer nanocomposites with improved efficiency and sustainability compared to existing ones. 展开更多

The objective of this study was to identify the suitable blended controlled-release nitrogen(N)fertilizer strategies(BCRNFs)for soft wheat production and to elucidate its underlying physiological mechanisms.A two-year field experiment conducted at two sites using two N application rates and three N fertilizer types.In each N rate,the N fertilizer types include:CK,common urea applied twice;BCRNF1,which featured a single basal application of a 3:2 blend of 60-d and 180-d controlled-release N fertilizers,aiming to delay N release until later growth stages;BCRNF2,which featured a single basal application of 3:4:3 blend of urea,60-d,and 180-d controlled-release N fertilizer,aiming to release N from early to middle growth stages.Compared with CK,BCRNF2 promoted starch synthesis and sucrose supply during the late grain-filling period of soft wheat,thereby increasing starch and amylose contents as well as the amyloseto-amylopectin ratio,while diluting protein and its component contents.The changes in these parameters mediated by BCRNF2 directly increased peak viscosity,trough viscosity,breakdown viscosity,final viscosity,and setback viscosity,ultimately improving soft wheat quality.BCRNF1 under reduced N application enhanced sucrose transport and starch synthesis capacity during the late growth period,which similarly supported the increase in starch content,the decrease in protein content,and the improvement of some key pasting characteristics.Therefore,BCRNF1 under reduced N conditions and BCRNF2 under conventional N conditions can enhance final grain quality and processing quality by increasing carbon metabolism during soft wheat grain filling,making them suitable for soft wheat production. 展开更多

The objective of this study was to identify an application strategy for a blend of two controlled-release nitrogen fertilizers(CRNFs) that optimized yield and N-use efficiency of late japonica rice in the Yangtze River Delta. In a two-year field experiment using high-yield split-applied urea(CK) and no-N fertilization as control(N0), nine CRNF treatments were evaluated for their effects on grain yield, N uptake(NUP), soil ammonium nitrogen(NH4+-N) dynamics, and ammonia volatilization(AV). The treatments included sulfur-coated urea(SCU), urease inhibitor urea(AHA), 90-d polymer-coated urea(P90), 120-d polymer-coated urea(P120), and five BBFs prepared by mixing CRNFs at a 3:7 ratio(AHAP90, SP90,AHAP120, SP120, and P90P120). Based on N release characteristics, CRNFs were categorized into four release modes: pre-positioned single-peak(PrSRM), post-positioned single-peak(PoSRM), decreasing double-peak(DDRM), and increasing double-peak(IDRM). Synchronization between soil NH4+-N dynamics under CRNFs and plant N uptake rate(NUPR) under CK was quantified using dynamic time warping(DTW), with smaller values indicating higher synchrony. Results showed that single-peak release modes significantly reduced grain yield and NUP by 12.6% and 10.5%, respectively. The IDRM treatment, a blend of 90-d and 120-d polymer-coated urea, showed NH4+-N supply dynamics most closely matching the N demand of high-yielding rice, with lower two-year average DTW values(SSRDTW 1.01, NUPSDTW1.72) than DDRM(1.03 and 2.00), which translated into increases in spikelet number, grain yield, and NUP by 4.49%,6.03%, and 4.85%, respectively, while decreasing AV by 86.7% compared with CK. One-time application of IDRM fertilizer can align soil NH4+-N supply with rice N demand, ensure high yield, and reduce N losses,providing an optimized fertilization strategy for sustainable rice production in the Yangtze River Delta. 展开更多

Phosphorus is one of the main contributors to the eutrophication of water bodies;therefore,phosphorus recycling from agricultural wastewater represents a synergistic approach to achieve both phosphorus management and effective resource use.However,the specific removal pathway remains to be optimized.This study investigated the adsorption effect of lanthanum-modified biochar(La-BC)made from agricultural waste on dissolved phosphorus(DP).The maximum unit adsorption capacity of La-BC reached 41.09 mg P/g,representing a 215.35%increase compared to the original biochar(BC)(C 0:500 mg/L;pH:7).Further,the removal effect of La-BC on agricultural non-point source pollutants with different particulate phosphorus(PP)percentages was investigated through dynamic interception and adsorption simulation experiments.The results showed that PP was mostly intercepted by quartz sand while DP was mainly adsorbed by La-BC.Thus,La-BC could effectively remove DP and PP from agricultural wastewater and delay the adsorption depletion point of the dynamic adsorption device,subsequently prolonging its service life.Finally,the agricultural availability of La-BC after adsorption and filtration(La-BC-P)was further explored by soil and plant cultivation.The results indicated that La-BC-P with adsorption interception of fertilizer distribution water had higher plant availability.A higher DP percentage increased the beneficial effects on soil nutrients(available phosphorus increased by 12–16-fold)and plant growth(plant fresh weight increased by 33%).This study innovatively verified the technical feasibility of the"agricultural waste-agricultural non-point source pollution treatment-carbon-based fertilizer"recycling model based on the characteristics of agricultural source wastewater. 展开更多

The excessive reliance on chemical inputs for managing soil nutrients and pathogens has raised concerns about their long-term sustainability and environmental impact.In contrast,the use of soil microbes offers an eco-friendly and efficient alternative for improving soil fertility and plant growth.Beneficial microorganisms,including plant growth-promoting rhizobacteria(PGPR),mycorrhizal fungi,and other soil organisms,play pivotal roles in nutrient cycling,organic matter decomposition,and nutrient availability improvement.This review explores the potential of leveraging microbial resources for sustainable soil nutrient management and resilient crop production.It delves into the intricate interactions between host plants and PGPR,particularly under nutrient-limited and fluctuating environmental conditions,with a focus on the molecular signaling pathways and mechanisms regulating these relationships.Furthermore,it emphasizes the role of advanced techniques and PGPR-responsive microRNAs to uncover the functional capabilities of microbial communities and their dynamic interactions with plants.These approaches pave the way for developing innovative,microbe-based strategies to optimize nutrient use efficiency,reduce dependency on synthetic fertilizers,and support sustainable agricultural practices. 展开更多

Hydrothermal cracking converts biomass waste into superior organic fertilizer by hydrolyzing it at temperatures of 180–220℃ and pressures of 1.5–2.45 MPa,enhancing treatment efficiency and nutritional value.Most of the research on hydrothermal cracking solid organic fertilizer(HCSOF)has been centered on its characterization and fertilizer properties;however,research is scarce regarding its greenhouse gas emissions and toxic metals(TMs).This study assesses the carbon and nitrogen retention rate and TMs of industrial HCSOF.Specifically,environmental impact was evaluated using indicators such as hazard quotient(HQ)and risk assessment code(RAC),with planting experiments conducted to assess TM's effect on soil and plants.The results indicate that industrial HCSOF has a high fixed carbon rate of up to 91.2%and a fixed nitrogen rate of 98.40%,manifesting the potential for reducing greenhouse gas emissions.Additionally,HCSOF contains high ecological safety of TMs such as Hg(HQ=0.008,RAC=0%),As(HQ=0.055,RAC=37.08%),Cd(HQ=0.708,RAC=1.76%),Pb(HQ=0.176,RAC=0.87%),and Cr(HQ=0.853,RAC=0.12%).After being applied to sandy soil,15,000 kg/ha of HCSOF can increase the organic matter and nutrients in both soil and maize straw,reducing TMs and their ecological risks.By obtaining a deeper understanding of the composition and practical application of industrial HCSOF,valuable insights can be offered to reduce greenhouse gas emissions and eliminate potential risks associated with TM pollution. 展开更多

The application of slow-controlled release fertilizer is a simple and labor-saving cultivation technology that can improve the yield and nitrogen use efficiency(NUE)of wheat,although research on the impact of a single application of controlledrelease nitrogen(N)fertilizers with different release periods on wheat grain quality is still limited.In this study,urease inhibitor urea(AHA),sulfur-coated urea(SCU),a combination of SCU and AHA fertilizer(BSAF)and blended slowcontrolled release fertilizer(BRNF)were used to investigate the effect of slow-controlled release fertilizers on the nutrient release,grain yield,NUE,and protein content of soft wheat.The goal was to determine the effect of a one-time application of controlled release fertilizer on wheat grain yield and protein content and its underlying mechanisms.The results showed that the different slow-controlled release fertilizer treatments had significantly different N release rates.AHA presented a fast release mode,while SCU and BSAF presented slow-release modes,and BRNF presented a controlled release mode.Compared with CK,BRNF increased grain yield and reduced the protein content of soft wheat,with an average increase of 6.73%in grain yield and a reduction of 1.85%in protein content.The higher N absorption of BRNF led to greater NUE,N agronomic efficiency(NAE)and N apparent recovery fraction(NRF).However,AHA,SCU and BSAF all showed the opposite trend.Compared with CK,BRNF improved post-anthesis dry matter accumulation(PDMA)and the contribution rate of dry matter accumulated post-anthesis to the grain(CDA),while reducing post-anthesis N accumulation(PNA)and the contribution rate of post-anthesis N accumulation to grain(CNA).The main reasons for the improvement in yield and reduction in protein content were related to the increases in PDMA and CDA,and the reductions in PNA and CNA,respectively.Therefore,BRNF is an effective agronomic strategy for promoting the coordination of grain yield and quality in soft wheat. 展开更多

Extremely high temperatures(HT)caused by global warming pose serious threats to rice production.Potassium(K)is critical for plant stress tolerance,but its role in mitigating heat damage remains unclear.This study aimed to elucidate how high panicle K application affects mid-season rice HT tolerance in central China.A two-year field experiment grew two rice cultivars(heat-resistant Shanyou 63,SY63;heatsensitive Liangyoupeijiu,LYPJ)under varying sowing dates and two K application levels(low K,LK,50 kg K ha-1;high K,HK,90 kg K ha-1)at the panicle initiation stage.Sowing date l(S1)and sowing date 2(S2)increased the risk of heat stress exposure.Compared with late sowing(S3)under LK,early sowing reduced the yield in LYPJ by 41,3%(S1)and 51.3%(S2)in 2022,and by 35.4%(S2)in 2023,but did not affect the yield in SY63.Compared with LK in the same sowing date,HK increased yield by 44.7%(S1)and 61.5%(S2)in LYPJ in 2022,and by 30.6%(S2)in 2023,whereas it showed no significant effect on SY63 yield.Structural equation modeling analysis indicated that the yield loss could be primarily attributed to heat intensity at the panicle initiation and maturity stages.HK increased stomatal conductance and improved leaf water potential,thereby reducing canopy temperature by 1,2-1.3℃at heading and 1.1-2.5℃at maturity.Concurrently,HK enhanced carbohydrate supply and elevated enzyme activity for sugars utilization in anthers,collectively enhancing pollen viability and spikelet fertility.HK optimized source-sink traits via increasing leaf area index,specific leaf weight,spikelets per unit leaf area,post-anthesis translocation of stem dry matter(47.5%-48.9% in 2022 and 24.0% in 2023),and postanthesis dry matter accumulation(33.0%-38.2% in 2022 and 19.0% in 2023).The study indicates that early sowing increases the risk of heat stress exposure for mid-season rice in central China,and the increase of panicle K application can mitigate yield loss by lessening canopy temperature and optimizing source-sink relationships. 展开更多

[Objectives]To evaluate the effects of deep vertical rotary tillage combined with organic carbon fertilizer on the improvement of acidic mountain soils.[Methods]A field experiment was conducted comparing three treatments:deep vertical rotary tillage,deep vertical rotary tillage combined with liquid organic carbon fertilizer,and traditional cultivation.The impacts of these treatments on the growth,biomass accumulation,yield,and quality of flue-cured tobacco were investigated.[Results]Deep vertical rotary tillage enhanced the growth of tobacco roots and aerial parts,as well as the accumulation of dry matter,nitrogen,phosphorus,potassium,and nicotine.The combination of vertical deep rotary tillage with organic carbon fertilizer promoted tobacco root development,increased leaf area,and facilitated the accumulation of dry matter,nitrogen,phosphorus,potassium,nicotine,and chlorine,thereby leading to an increase in the yield of flue-cured tobacco.The application of liquid organic carbon fertilizer enhanced the potassium and sugar content of flue-cured tobacco,but it also resulted in an increased nicotine content.Therefore,flue-cured tobacco cultivation is recommended under acidic soil conditions in mountainous regions,employing deep vertical rotary tillage.[Conclusions]The application of liquid organic carbon fertilizers at the time of transplanting,combined with rooting solution irrigation,and again 20 d after transplanting combined with topdressing,effectively promotes the growth and dry matter accumulation of flue-cured tobacco. 展开更多

Using phosphorus(P)fertilizers has historically increased agricultural productivity,yet the highly dissipative nature of phosphate rock and the low effciency due to soil fxation and runoff raise sustainability concerns.Algae fertilizers have emerged as a promising eco-friendly alternative.However,the potential of algae fertilizers for providing sustained P availability and their impacts on plant growth,soil microbes,and nutrient cycling remains to be explored.In this study,we developed a polyphosphate-enriched algae fertilizer(PEA)and conducted comparative experiments with chemical P fertilizers(CP)through soil and solution cultures,as well as crop growth trials.Soil cultivation experiments showed that PEA released twice as much labile P as initially available in the soil,and it functioned as a slow-release P source.In contrast,soils treated with CP initially exhibited high levels of labile P,which was gradually converted to stable forms,but it dropped to 30%of the labile P level in PEA after three months.Further tests revealed that the slow release of P from PEA was linked to increased microbial activity,and the microbial biomass P(MBP)content was about eight times higher than in soils treated with CP after three months,resulting in a 75%decline in the microbial biomass carbon(MBC)to MBP ratio.Microbial diversity analysis showed that algae fertilizers could recruit more benefcial microbes than CP,like phosphorus-solubilizing bacteria,plant growth-promoting bacteria,and stress-resistant bacteria.Crop pot experiments,along with amplicon and metagenomic analysis of tomato root-associated microbes,revealed that algae fertilizers including PEA promoted plant growth comparable to CP,and enhanced soil P cycling and overall nutrient dynamics.These data showed that algae fertilizers,especially PEA,can stabilize soil P fertility and stimulate plant growth through their slow P release and the recruitment of benefcial microbes.Our study highlights the potential of PEA to foster sustainable agriculture by mitigating the P scarcity and soil P loss associated with chemical fertilizers and improving plant growth and soil health. 展开更多

The advent of civilization has made humans dependent on plants for food and medicine,leading to the intensification of agricultural production.The intense cultivation of crops has resulted in the depletion of available nutrients from soil,thereby demanding the application of excess nutrients to soil to improve yield.Thus,mineral fertilizer discovery and application have,in many ways,contributed greatly to meeting global food demands.However,aside from the positive effects of mineral fertilizers,their excessive application to soil produces large amounts of pollutants that affect environmental sustainability.This necessitates the study of the major mineral fertilizer elements(nitrogen(N),phosphorus(P),and potassium(K)),the forms in which they are applied to soil,and their chemistryeactions in soil.Here,we reviewed the forms of different N,P,and K mineral fertilizers to provide current knowledge on their constituents,the chemistry of N,P,and K in soil to understand the reactions they undertake in soil,the efficient methods of fertilizer application for environmental sustainability,the effects of mineral fertilizer loss to the environment,and improved fertilization technologies for environmental sustainability.Nanofertilizers are a promising technology for sustainable agricultural production and are discussed in detail in this review. 展开更多

The rhizosphere microbial community is significantly influenced by the application of chemical fertilizers,with potassium(K)fertilizer playing a crucial role in enhancing both the yield and quality of sugarcane.However,limited studies have investigated how K fertilizer impacts sugarcane productivity through synergistic interactions between microorganisms and the soil environment.This study aims to explore the regulatory effects of K(K2SO4,50%K2O)fertilizer on bacterial and fungal communities and to examine the mechanisms linking microbial structure to sugarcane yield.A field experiment was conducted with five levels of K fertilizer to evaluate microbial community structure,soil properties,and enzyme activities that affect sugarcane productivity.The results indicated that K application significantly altered soil properties,with a threshold of 150 kg/hm2identified,where shifts in both bacterial and fungal diversity were observed.Linear discriminant analysis(LEfSe)revealed changes in the abundance of microbial taxa,including Proteobacteria,Acidobacteriota,Actinobacteriota,and various fungal groups,across different K levels.Redundancy analysis(RDA)demonstrated that soil properties and enzyme activities(e.g.,catalase and urease)significantly influenced microbial community structure.Furthermore,partial least squares path modeling analysis(PLS-PM)showed that changes in the microbial community directly affected sugarcane yield.The results of this study indicate that K fertilizer application indirectly enhances sugarcane yield and sucrose content by promoting microbial diversity and soil enzyme activity,ultimately increasing crop productivity.This provides valuable insights into the dual regulatory effects of K fertilizer on rhizosphere bacteria and fungi,emphasizing the key microbial taxa and soilenvironment interactions that drive sugarcane productivity and sucrose accumulation. 展开更多

To improve the storage quality of tomatoes,an optimized water and fertilizer management scheme was developed by exploring the dynamic effects of water-fertilizer coupling on tomato quality during storage.A dynamic model of tomato fruit quality stored under 4°C was established,with nitrogen,phosphorus,and potassium application rates as experimental factors.A half-four-element quadratic rotary composite design(20 treatments)was adopted.Tomatoes were stored at 4°C for 28 d,and quality indicators(hardness,soluble sugar,lycopene,and vitamin C)were analyzed using Pearson correlation and comprehensive evaluation methods.A response model linking the comprehensive quality score to fertilizer levels was constructed.Results demonstrated that appropriate water-fertilizer ratios enhanced tomato quality,while excessive or insufficient parameters reduced it.Changes in quality indicators during storage followed first-order kinetic equations.Optimized parameters through tomato quality index(TQI)analysis included irrigation at 602 mm·hm-2,nitrogen at 570 kg·hm-2,phosphorus at 70 kg·hm-2,and potassium at 738 kg·hm-2,which effectively improved storage quality with satisfactory model fit and storability. 展开更多

Both soil organic carbon (SOC) and iron (Fe) oxide content, among other factors, drive the formation and stability of soil aggregates.However, the mechanism of these drivers in greenhouse soil fertilized with organic fertilizer is not well understood.In a 3-year field experiment, we aimed to investigate the factors which drive the stability of soil aggregates in greenhouse soil.To explore the impact of organic fertilizer on soil aggregates, we established four treatments:no fertilization (CK);inorganic fertilizer (CF);organic fertilizer (OF);and combined application of inorganic and organic fertilizers(COF).The application of organic fertilizer significantly enhanced the stability of aggregates, that is it enhanced the mean weight diameter, geometric mean diameter and aggregate content (%) of>0.25 mm aggregate fractions.OF and COF treatments increased the concentration of SOC, especially the aliphatic-C, aromatic-C and polysaccharide-C components of SOC, particularly in>0.25 mm aggregates.Organic fertilizer application significantly increased the content of free Fe(Fed), reactive Fe (Feo), and non-crystalline Fe in both bulk soil and aggregates.Furthermore, non-crystalline Fe showed a positive correlation with SOC content in both bulk soil and aggregates.Both non-crystalline Fe and SOC were significantly positively correlated with>2 mm mean weight diameter.Overall, we believe that the increase of SOC, aromatic-C, and non-crystal ine Fe concentrations in soil after the application of organic fertilizer is the reason for improving soil aggregate stability. 展开更多

The application of organic fertilizers has become an increasingly popular practice in maize production to reduce thegaseous nitrogen(N) loss and soil degradation caused by inorganic fertilizers. Organic fertilizer plays a key rolein improving soil quality and stabilizing maize yields, but few studies have compared different substitution rates. Afield study was carried out in 2021 and 2022, based on a long-term trial initiated in 2016, which included five organicfertilizer N substitution rates with equal inputs of 200 kg N ha–1: 0% organic fertilizer(T1, 100% inorganic fertilizer),50.0% organic+50.0% inorganic fertilizer(T2), 37.5% organic+62.5% inorganic fertilizer(T3), 25.0% organic+75.0%inorganic fertilizer(T4), and 12.5% organic+87.5% inorganic fertilizer(T5), as well as a no fertilizer control(T6). Theresults of the two years showed that T3 and T1 had the highest grain yield and biomass, respectively, and there wasno significant difference between T1 and T3. Compared with T1, the 12.5, 25.0, 37.5, and 50.0% substitution rates in T5, T4, T3, and T2 significantly reduced total nitrogen losses(NH3, N2O) by 8.3, 16.1, 18.7, and 27.0%, respectively.Nitrogen use efficiency(NUE) was higher in T5, T3, and T1, and there were no significant differences among them.Organic fertilizer substitution directly reduced NH3volatilization and N2O emission from farmland by lowering theammonium nitrogen and alkali-dissolved N contents and by increasing soil moisture. These substitution treatmentsreduced N2O emissions indirectly by regulating the abundances of AOB and nirK-harboring genes by promotingsoil moisture. Specifically, the 37.5% organic fertilizer substitution reduces NH3volatilization and N2O emission from farmland by reducing the ammonium nitrogen and alkali-dissolved N contents and increasing moisture, which negatively regulate the abundance of AOB and nir K-harboring genes to reduce N2O emissions indirectly in rainfed maize fields on the Loess Plateau of China. 展开更多
