This study evaluated stranded holopelagic Sargassum as a co-feedstock for vermicomposting. Methods Beach wrecked Sargassum was used in the vermicomposting system using Eisenia fetida (red wrigglers) and mixed in a ratio of 1:1 with Sargassum : cow manure (fresh weight), with three independent vermicomposting containers per treatment. After a 90-day period, measurements of final abundance and reproductive performance, vermicast composition and sanitary quality, culturable putative plant growth-promoting microorganisms colony forming units, and bacterial and fungal community profiles were assessed. The vermicast was subsequently evaluated in tomato and sweet pepper greenhouse experiments using 25 plants per treatment. Results and discussion After the 90-day experimental period, the total worm population reached 310 worms in the cow manure-only system (SVC1) and 575 worms in the cow manure + Sargassum system (SVC2), corresponding to net increases of 210% and 475%, respectively, relative to the initial stocking density of 100 worms, with significantly higher adult biomass, cocoon production, and juvenile abundance in SVC2 ( p \u003C 0.05). Concentrations of Cd, Hg, Ni, Pb, Cu and Zn were below the limits established for organic soil improvers under Regulation (EU) 2019\u002F1009. Presumptive Escherichia coli and Salmonella spp. were not detected, and total coliforms were recorded at 1.0 × 10 2 CFU g −1 . SVC2 showed higher culturable counts of putative Azotobacter and phosphate-solubilizing microorganisms, while SVC1 had higher putative Pseudomonas counts. SVC1 had higher observed relative abundances of genera such as Lacunisphaera and Haliscomenobacter , while SVC2 had higher relative abundances of Luteolibacter, Simiduia, Cellvibrio, and Ilumatobacter , and had a shared core microbiome comprising Luteolibacter, Cellvibrio, Algoriphagus, Verrucosispora, and Hydrogenophaga. Although the bacterial and fungal communities showed visual separation in the ordination analyses, PERMANOVA did not detect statistically significant differences between treatments ( p = 0.10). Vermicast application significantly enhanced fruit yield, with SVC2-100 increasing mean cumulative tomato yield from 2.6 to 7.5 kg plant −1 and SVC2-200 increasing sweet pepper yield from 1.3 to 4.0 kg plant −1 over the production period, corresponding to increases of 185.5% and 203.0%, respectively, in comparison to the Control. The study demonstrated the potential of pelagic Sargassum biomass as a co-feedstock for vermicomposting and as a circular bioeconomy approach for producing agricultural amendments. However, field validation, long-term soil and crop safety assessments, and extension and farmer training are required before wider agricultural adoption.","全球性季节性的全浮游型马尾藻（holopelagic Sargassum）大量堆积已对加勒比海沿岸生态系统及社区造成影响，因此，寻求可持续的资源化利用策略，将此类生物质转化为高附加值产品至关重要。本研究评估了搁浅的全浮游型马尾藻作为蚯蚓堆肥（vermicomposting）共基质的可行性。方法：将海滩搁浅的马尾藻与牛粪按鲜重1:1的比例混合，采用赤子爱胜蚓（Eisenia fetida，俗称红蚯蚓）进行蚯蚓堆肥，每个处理设置三个独立的堆肥容器。经过90天的试验期后，测定了蚯蚓最终丰度与繁殖性能、蚓粪（vermicast）组成及卫生质量、可培养的推定植物促生微生物菌落形成单位，以及细菌和真菌群落结构。随后，在番茄和甜椒温室试验中评估了蚓粪的肥效，每个处理使用25株植物。结果与讨论：90天试验期结束后，纯牛粪系统（SVC1）的蚯蚓总种群数量达到310条，而牛粪+马尾藻系统（SVC2）达到575条，相对于初始投放的100条，净增长率分别为210%和475%，且SVC2处理中成蚓生物量、茧产量及幼蚓丰度均显著高于SVC1（p \u003C 0.05）。Cd、Hg、Ni、Pb、Cu和Zn的浓度均低于欧盟法规(EU) 2019\u002F1009中规定的有机土壤改良剂限量标准。未检出推定的大肠杆菌（Escherichia coli）和沙门氏菌（Salmonella spp.），总大肠菌群数为1.0 × 10² CFU g⁻¹。SVC2中可培养的推定固氮菌（Azotobacter）和溶磷微生物数量较高，而SVC1中推定假单胞菌（Pseudomonas）数量较高。SVC1中Lacunisphaera和Haliscomenobacter等属的相对丰度较高，而SVC2中Luteolibacter、Simiduia、Cellvibrio和Ilumatobacter的相对丰度较高，且两者共享的核心微生物组包含Luteolibacter、Cellvibrio、Algoriphagus、Verrucosispora和Hydrogenophaga。尽管排序分析中细菌和真菌群落在视觉上呈现分离趋势，但PERMANOVA分析未检测到处理间的统计学显著差异（p = 0.10）。施用蚓粪显著提高了果实产量，其中SVC2-100处理使番茄平均累计产量从2.6 kg\u002F株增至7.5 kg\u002F株，SVC2-200处理使产量进一步增加。",null,"Frontiers in Sustainable Food Systems","2026-09-03T00:00:00Z","论文",10,false,70,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":21,"relevant":22,"comment":23},12,20,18,13,7,1,"研究马尾藻与牛粪共堆肥的农艺效果，数据详实，对有机农业废弃物资源化有参考价值。",[25],{"name":10,"url":6},[27,28,29,30,31],"土壤改良","农业科技","循环农业","蚯蚓堆肥","马尾藻",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},"H2","soil","土壤健康与改良","\u002Ftopic\u002Fenvironment\u002Fsoil","H",[],{"status":40,"locked":14,"version":41,"method":42,"evidence":43},"classified","2026-10-22.2","rules",{"candidates":44,"agricultural_evidence":46},[45,51,59,66],{"code":33,"score":21,"supported":46,"title":47,"abstract":48,"tags":50},true,[],[49,34],"土壤",[27],{"code":52,"score":53,"supported":46,"title":54,"abstract":55,"tags":58},"B1",6,[],[56,57],"番茄","tomato",[],{"code":60,"score":53,"supported":46,"title":61,"abstract":62,"tags":65},"B7",[],[63,64],"温室","greenhouse",[],{"code":67,"score":22,"supported":14,"title":68,"abstract":69,"tags":70},"H8",[],[],[29],[72,73],"农业科技 土壤改良 循环农业 蚯蚓堆肥","农业科技 土壤改良","农业科技土壤改良循环农业蚯蚓堆肥-1612",2,"10.3389\u002Ffsufs.2026.1914954",{"doi":76,"openalex_id":78,"authors":79,"venue":10,"cited_by_count":97,"oa_url":6,"card":98,"direction":102,"ingested_from":104},"W7207772438",[80,82,84,86,88,90,92,95],{"name":81,"orcid":9},"Omar Ali",{"name":83,"orcid":9},"Simran Chadee",{"name":85,"orcid":9},"Arvinda Bharat",{"name":87,"orcid":9},"Uddesh Sahadeo",{"name":89,"orcid":9},"Adana Lutchman",{"name":91,"orcid":9},"Pragadish Jayaraj",{"name":93,"orcid":94},"Adesh Ramsubhag","https:\u002F\u002Forcid.org\u002F0000-0002-5863-0457",{"name":96,"orcid":9},"Jayaraj Jayaraman",0,{"tldr":99,"method":100,"finding":101,"direction":102,"opportunity":103},"研究将马尾藻与牛粪共堆肥，评估蚯蚓堆肥效果及对番茄辣椒产量的影响。","使用赤子爱胜蚓，1:1混合马尾藻与牛粪，90天堆肥后分析微生物及温室试验。","添加马尾藻提高蚯蚓繁殖和番茄产量，重金属及病原菌达标，微生物群落有差异。","农业绿色发展与碳","可探究马尾藻堆肥对土壤微生物群落长期影响及不同作物响应，优化配比以提升农业效益。","openalex","2026-09-04T23:30:08.170298Z",{"total":53,"page":22,"page_size":53,"items":107},[108,190,234,338,383,450],{"id":109,"title":110,"url":111,"summary":112,"summary_zh":113,"content":9,"source_name":10,"source_url":111,"published_at":114,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":115,"score_detail":116,"sources":118,"tags":120,"primary_topic":124,"secondary_topics":125,"classification":132,"search_phrases":159,"slug":162,"view_count":163,"doi":164,"paper":165,"created_at":189},1389,"Coconut husk biochar as a climate-smart soil amendment: optimizing pyrolysis temperature and feedstock cut size for a carbon-rich, waste-derived agricultural input","https:\u002F\u002Fdoi.org\u002F10.3389\u002Ffsufs.2026.1899786","Climate change is steadily eroding agricultural productivity through soil degradation, water and salinity stress, and declining nutrient-use efficiency, while the heavy reliance on conventional mineral fertilizers contributes to greenhouse-gas emissions, nutrient losses, and, in some contexts, reduced soil biological activity. Biochar from lignocellulosic agro-residues can convert low-value waste into a carbon-rich material that has been reported to carry and slowly release mineral and organic nutrients, aligning with the goals of organo-mineral fertilization. This study evaluated the feasibility of coconut ( Cocos nucifera L.) husk, a major underutilized by-product of the coconut industry-as a feedstock for such an amendment by optimizing two production variables: pyrolysis temperature and feedstock cut size. A laboratory experiment combined four cut sizes (1\u002F8, 1\u002F4, 1\u002F2, and chips) with five temperatures (275 °C, 325 °C, 375 °C, 425 °C, and 475 °C) in a completely randomized design (60 samples), followed by a field-scale trial using a double-chamber pyrolyzer comparing compacted versus loosely packed loading densities. Conversion efficiency and proximate composition (moisture, volatile matter, ash, and fixed carbon) were determined and analyzed by two-way factorial ANOVA to test the temperature × cut-size interaction, followed by one-way ANOVA to characterize the main effects once the interaction proved non-significant. Conversion efficiency ranged from 36.6% to 68.3% and declined with increasing temperature, whereas volatile matter decreased, and both ash (3.6%–12.3%) and fixed carbon (0.27%–5.54%) increased significantly with temperature ( p \u003C 0.05); fixed carbon is an operationally defined proximate fraction and was not corroborated by elemental (H\u002FC, O\u002FC) ratios, aromaticity or stability indices, or mineralization assays. The 1\u002F4 cut size offered the best balance of yield, carbonization, and operability and was selected for field trials, where compacted loading achieved a significantly higher conversion efficiency (46.95%) than loose packing (40.90%; p = 0.03). A resource-utilization analysis over a 60-year plantation lifespan indicated that biochar amendment could reduce husk demand by approximately 94% relative to direct mulching and 81% relative to husk burial. Moderate pyrolysis (325 °C–375 °C) with a 1\u002F4 cut size produced a carbon-rich biochar with potential use as a component or carrier of an organo-mineral soil amendment, suggesting a practical route to valorize coconut husk waste for resilient tropical cropping systems. Agronomic performance, nutrient release, and carbon persistence were not assessed in the present study.","气候变化正通过土壤退化、水分与盐分胁迫以及养分利用效率下降，持续削弱农业生产能力，而对常规矿质肥料的严重依赖则导致温室气体排放、养分损失，并在某些情况下降低土壤生物活性。利用木质纤维素类农业残余物制备的生物炭，可将低价值废弃物转化为富碳材料，据报道其能够携带并缓慢释放矿质和有机养分，与有机-矿质施肥的目标相契合。本研究以椰子（*Cocos nucifera* L.）壳——椰子产业中一种主要但未被充分利用的副产物——为原料，通过优化两个生产变量（热解温度和原料切块尺寸）评估其作为此类土壤改良剂的可行性。实验室试验采用完全随机设计（60个样品），将四种切块尺寸（1\u002F8、1\u002F4、1\u002F2英寸及碎片）与五个温度水平（275 °C、325 °C、375 °C、425 °C和475 °C）组合，随后利用双室热解炉进行田间规模试验，比较压实装料与松散装料两种填充密度。测定转化效率和工业组成（水分、挥发分、灰分和固定碳），并采用双因素方差分析检验温度与切块尺寸的交互效应；由于交互效应不显著，随后采用单因素方差分析表征主效应。转化效率范围为36.6%–68.3%，随温度升高而下降；挥发分随温度升高而减少，而灰分（3.6%–12.3%）和固定碳（0.27%–5.54%）均随温度升高显著增加（*p* \u003C 0.05）；固定碳为操作定义的工业分析组分，未得到元素比（H\u002FC、O\u002FC）、芳香性或稳定性指数以及矿化试验的验证。1\u002F4英寸切块尺寸在产率、碳化程度和可操作性之间达到最佳平衡，故被选用于田间试验；其中压实装料的转化效率（46.95%）显著高于松散装料（40.90%；*p* = 0.03）。基于60年种植周期的资源利用分析表明，与直接覆盖还田相比，生物炭改良可使椰壳需求量减少约94%，与埋壳处理相比减少约81%。中等温度热解（325 °C–375 °C）配合1\u002F4英寸切块尺寸可制备富碳生物炭，有望作为有机-矿质土壤改良剂的组分或载体，为椰壳废弃物的增值利用提供了一条切实可行的途径。","2026-09-01T00:00:00Z",69,{"impact":17,"substance":18,"depth":19,"authority":17,"freshness":21,"relevant":22,"comment":117},"研究优化椰壳生物炭制备条件，为废弃物资源化与气候智慧农业提供数据支撑，但未涉及农艺效果，影响有限。",[119],{"name":10,"url":111},[121,27,28,122,123],"生物炭","椰壳利用","固碳减排",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[126],{"code":127,"slug":128,"name":129,"path":130,"parent_code":131},"F3","fertilizers","肥料与水肥一体化","\u002Ftopic\u002Finputs-equipment\u002Ffertilizers","F",{"status":40,"locked":14,"version":41,"method":42,"evidence":133},{"candidates":134,"agricultural_evidence":46},[135,140,148,152],{"code":33,"score":136,"supported":46,"title":137,"abstract":138,"tags":139},16,[34],[49,34],[27,121],{"code":127,"score":141,"supported":46,"title":142,"abstract":143,"tags":147},9,[],[144,145,146],"施肥","肥料","fertilization",[],{"code":60,"score":53,"supported":46,"title":149,"abstract":150,"tags":151},[],[63,64],[],{"code":153,"score":53,"supported":46,"title":154,"abstract":155,"tags":158},"H7",[],[156,157],"气候变化","climate change",[],[160,161],"农业科技 固碳减排 土壤改良 椰壳利用","农业科技 固碳减排","农业科技固碳减排土壤改良椰壳利用-1389",3,"10.3389\u002Ffsufs.2026.1899786",{"doi":164,"openalex_id":166,"authors":167,"venue":10,"cited_by_count":97,"oa_url":183,"card":184,"direction":102,"ingested_from":104},"W7204915118",[168,170,172,175,177,180],{"name":169,"orcid":9},"T.

In this context, the present study evaluated the short-term performance of pelletized compost (CC) and vermicompost (VC) produced from vineyard prunings and sewage sludge on lettuce ( Lactuca sativa L.) growth, leaf biochemical traits, mineral composition, and soil chemical properties. The performance of both organic products was compared with a commercial organomineral fertilizer (CF) and an unfertilized control (CT). Methods A completely randomized greenhouse pot experiment was conducted for 55 days comprising four treatments with eight replicates each. . Data were analyzed by one-way ANOVA followed by Tukey´s HSD test at p \u003C 0.05, with non-parametric analysis used when ANOVA assumptions were not met. Results and discussion At the end of the experiment, organic amendments performed comparably to the commercial fertilizer CF for most morphological parameters, despite differences in absolute nutrient inputs among treatments, although shoot fresh weight remained higher under CF. Leaf biochemical responses varied among treatments: CC and CF exhibited high chlorophyll and carotenoid contents, whereas VC and CT showed lower pigment concentrations. Total soluble sugars were highest in CT and lowest in CF, while total protein and phenolic contents were not significantly affected by treatment. Leaf macronutrient concentrations under CC and VC were generally comparable to CF, while for micronutrients Fe and Mn concentrations were higher in CF. Final soil analyses showed higher organic matter, extractable P and K, and cation exchange capacity under organic fertilization, whereas CF showed the lowest soil pH.

Conclusions These findings support the potential use of compost and vermicompost derived from vineyard pruning residues and sewage sludge as recycled organic amendments for horticultural production.

Low-grade rock phosphate (RP) is an underutilised, economical indigenous P source, but its agronomic effectiveness is often limited by low solubility and slow P release. This study evaluated the effectiveness of indigenous low-grade Udaipur rock phosphate (URP) amended with elemental sulphur (S) and phosphate-solubilising bacteria (PSB) for improving P availability, maize growth, yield and P-use efficiency in two contrasting soil orders, Alfisol and Vertisol. Methods A pot experiment comprising nine P management treatments, including single super phosphate (SSP), URP, PSB ( Burkholderia cenocepacia ) and S combinations was conducted under maize. Soil available P, plant height, number of leaves, leaf area index, dry matter accumulation, grain yield, P uptake, harvest index (HI), physiological P-use efficiency (PPUE) and P harvest index (PHI) were assessed. Results Across treatments, agronomic performance and soil P availability were consistently higher in the Vertisol compared to the Alfisol. Amendment-assisted URP improved grain yield by up to 68% over URP alone in Alfisol and 35% in Vertisol. Compared with 100% P through SSP, grain yield increased by 38.7% and 24.8% under URP 100 + S 25 + PSB 5 and by 42.7% and 21.0% under URP 150 + S 10 + PSB 5 in Alfisol and Vertisol, respectively. Both treatments maintained plant growth, dry matter production, grain yield, and P uptake comparable with SSP 150 + PSB 5 . Soil available P increased with P fertilisation, with URP 100 + S 25 + PSB 5 and URP 150 + S 10 + PSB 5 maintaining levels close to SSP 150 + PSB 5 and higher than URP alone. Despite these differences in P acquisition, PPUE, PHI and HI remained statistically similar, indicating that treatments improved overall P supply and biomass production proportionally rather than altering P partitioning efficiency. Discussion Overall, combining URP with PSB and S improved the agronomic effectiveness of a low-solubility P source and produced maize productivity comparable with a higher rate of soluble P fertiliser under controlled conditions. Efficient utilisation of indigenous low-grade RP through suitable solubilising amendments offers a promising approach for improving crop yield and sustainable nutrient management, with future scope for field-scale validation.","引言 高效的磷（P）管理对于提高作物生产力、同时减少对高能耗、高溶解度磷肥的依赖至关重要。低品位磷矿粉（RP）是一种尚未充分利用且经济可行的本土磷源，但其农艺有效性往往受限于低溶解度和磷释放缓慢。本研究评估了经元素硫（S）和溶磷细菌（PSB）改良的本土低品位乌代布尔磷矿粉（URP）在两种对比鲜明的土壤类型——淋溶土和变性土中提高磷有效性、玉米生长、产量及磷利用效率的效果。方法 在玉米上开展了一项盆栽试验，包含9个磷管理处理，涉及过磷酸钙（SSP）、URP、PSB（洋葱伯克霍尔德菌）及硫的组合。测定了土壤有效磷、株高、叶片数、叶面积指数、干物质积累、籽粒产量、磷吸收量、收获指数（HI）、生理磷利用效率（PPUE）和磷收获指数（PHI）。结果 在所有处理中，变性土的农艺表现和土壤磷有效性均 consistently 高于淋溶土。改良剂辅助的URP使淋溶土和变性土的籽粒产量较单施URP分别最高提高68%和35%。与100%磷通过SSP施用相比，在淋溶土和变性土中，URP 100 + S 25 + PSB 5处理的籽粒产量分别增加38.7%和24.8%，URP 150 + S 10 + PSB 5处理分别增加42.7%和21.0%。这两个处理在植株生长、干物质生产、籽粒产量和磷吸收方面均与SSP 150 + PSB 5相当。土壤有效磷随磷肥施用而增加，URP 100 + S 25 + PSB 5和URP 150 + S 10 + PSB 5处理的水平接近SSP 150 + PSB 5，且高于单施URP。尽管磷获取方面存在这些差异，但PPUE、PHI和HI在各处理间统计上保持相似，表明这些处理按比例提高了整体磷供应和生物量生产，而非改变磷分配效率。讨论 总体而言，将URP与PSB和硫结合提高了低溶解度磷源的农艺有效性，并在受控条件下产生了与较高用量可溶性磷肥相当的玉米生产力。通过适宜的增溶改良剂高效利用本土低品位磷矿粉，为提高作物产量和可持续养分管理提供了一种有前景的途径，未来有待田间规模的验证。","2026-10-01T00:00:00Z",73,{"impact":392,"substance":393,"depth":394,"authority":20,"freshness":243,"relevant":22,"comment":395},14,21,17,"盆栽试验证明硫与解磷菌活化低品位磷矿粉可使玉米增产并媲美速效磷肥，对磷资源高效利用有参考价值，但尚属受控条件研究、缺乏田间验证，未达重大突破层级。",[397],{"name":10,"url":386},[206,27,399,400,401],"养分利用效率","磷肥减量","微生物菌剂",{"code":211,"slug":212,"name":206,"path":213,"parent_code":214},[404],{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},{"status":40,"locked":14,"version":41,"method":42,"evidence":406},{"candidates":407,"agricultural_evidence":46},[408,412,416],{"code":211,"score":259,"supported":46,"title":409,"abstract":410,"tags":411},[212],[206,212],[206],{"code":33,"score":259,"supported":46,"title":413,"abstract":414,"tags":415},[34],[49,34],[27],{"code":127,"score":381,"supported":46,"title":417,"abstract":418,"tags":420},[],[419],"养分管理",[399],[422,423],"低品位磷矿粉
