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。","Frontiers in Sustainable Food Systems","2026-09-03T00:00:00Z","论文",70,{"impact":81,"substance":82,"depth":83,"authority":84,"freshness":85,"relevant":21,"comment":86},12,20,18,13,7,"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。",[88],{"name":76,"url":73},[90,27,91,92,93],"土壤改良","循环农业","蚯蚓堆肥","马尾藻",{"code":32,"slug":33,"name":34,"path":35,"parent_code":36},[],{"status":39,"locked":40,"version":41,"method":42,"evidence":97},{"candidates":98,"agricultural_evidence":14},[99,103,110,117],{"code":32,"score":85,"supported":14,"title":100,"abstract":101,"tags":102},[],[49,33],[90],{"code":104,"score":68,"supported":14,"title":105,"abstract":106,"tags":109},"B1",[],[107,108],"番茄","tomato",[],{"code":111,"score":68,"supported":14,"title":112,"abstract":113,"tags":116},"B7",[],[114,115],"温室","greenhouse",[],{"code":57,"score":21,"supported":40,"title":118,"abstract":119,"tags":120},[],[],[91],[122,123],"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":126,"openalex_id":128,"authors":129,"venue":76,"cited_by_count":147,"oa_url":73,"card":148,"direction":152,"ingested_from":154},"W7207772438",[130,132,134,136,138,140,142,145],{"name":131,"orcid":8},"Omar Ali",{"name":133,"orcid":8},"Simran Chadee",{"name":135,"orcid":8},"Arvinda Bharat",{"name":137,"orcid":8},"Uddesh Sahadeo",{"name":139,"orcid":8},"Adana Lutchman",{"name":141,"orcid":8},"Pragadish Jayaraj",{"name":143,"orcid":144},"Adesh Ramsubhag","https:\u002F\u002Forcid.org\u002F0000-0002-5863-0457",{"name":146,"orcid":8},"Jayaraj Jayaraman",0,{"tldr":149,"method":150,"finding":151,"direction":152,"opportunity":153},"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",{"id":157,"title":158,"url":159,"summary":160,"summary_zh":161,"content":8,"source_name":76,"source_url":159,"published_at":162,"category":78,"cover_url":8,"hotness":13,"is_selected":40,"score":163,"score_detail":164,"sources":166,"tags":168,"primary_topic":172,"secondary_topics":173,"classification":180,"search_phrases":207,"slug":210,"view_count":46,"doi":211,"paper":212,"created_at":236},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":81,"substance":82,"depth":83,"authority":81,"freshness":85,"relevant":21,"comment":165},"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。",[167],{"name":76,"url":159},[169,90,27,170,171],"生物炭","椰壳利用","固碳减排",{"code":32,"slug":33,"name":34,"path":35,"parent_code":36},[174],{"code":175,"slug":176,"name":177,"path":178,"parent_code":179},"F3","fertilizers","肥料与水肥一体化","\u002Ftopic\u002Finputs-equipment\u002Ffertilizers","F",{"status":39,"locked":40,"version":41,"method":42,"evidence":181},{"candidates":182,"agricultural_evidence":14},[183,188,196,200],{"code":32,"score":184,"supported":14,"title":185,"abstract":186,"tags":187},16,[33],[49,33],[90,169],{"code":175,"score":189,"supported":14,"title":190,"abstract":191,"tags":195},9,[],[192,193,194],"施肥","肥料","fertilization",[],{"code":111,"score":68,"supported":14,"title":197,"abstract":198,"tags":199},[],[114,115],[],{"code":201,"score":68,"supported":14,"title":202,"abstract":203,"tags":206},"H7",[],[204,205],"气候变化","climate change",[],[208,209],"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","10.3389\u002Ffsufs.2026.1899786",{"doi":211,"openalex_id":213,"authors":214,"venue":76,"cited_by_count":147,"oa_url":230,"card":231,"direction":152,"ingested_from":154},"W7204915118",[215,217,219,222,224,227],{"name":216,"orcid":8},"T.

Legumes, termed as the \"poor man's meat\" for their high protein content and low cost, are critical for enhancing nutritional security in resource-limited communities. This review emphasises agronomic biofortification as a rapid, promising and versatile strategy for enhancing essential micronutrients, particularly iron (Fe), zinc (Zn) and selenium (Se), in legume grains. It discusses different agronomic strategies such as soil and foliar fertilisation, seed priming and biological interventions. Unlike conventional breeding and genetic methods, which require longer to develop, these agronomic techniques can increase nutrient density within a single cropping cycle. It also focuses on the scope of agronomic biofortification and addresses its challenges related to nutritional bioavailability, notably the inhibitory effect of anti-nutritional factors such as phytates and discusses strategies to enhance nutrient absorption through promoter compounds. Furthermore, emerging technologies such as nanotechnology and precision agriculture are recognised as promising innovations to enhance nutrient use efficiency (NUE) and ensure environmental sustainability. Overall, agronomic biofortification provides a sustainable pathway to combat micronutrient malnutrition and this approach requires integration with genetic advancements and supportive agricultural policies for its long-term success.","隐性饥饿是指微量营养素缺乏，影响着全球近二十亿人口，尤其是在依赖高热量但营养贫乏的主食的地区。豆类因其高蛋白质含量和低成本而被称为“穷人的肉食”，对于提升资源有限社区的营养安全至关重要。本综述强调农艺生物强化作为一种快速、有前景且多功能的策略，用于增强豆类籽粒中的必需微量营养素，特别是铁（Fe）、锌（Zn）和硒（Se）。文中讨论了不同的农艺策略，如土壤和叶面施肥、种子引发以及生物干预。与传统育种和遗传方法相比，这些农艺技术能在单一作物周期内提高营养密度，而传统方法则需要更长时间来开发。综述还聚焦于农艺生物强化的应用范围，并探讨了其与营养生物可利用性相关的挑战，特别是植酸盐等抗营养因子的抑制作用，同时讨论了通过促进化合物增强营养吸收的策略。此外，纳米技术和精准农业等新兴技术被认为是提高养分利用效率（NUE）并确保环境可持续性的有前景的创新。总体而言，农艺生物强化为对抗微量营养素营养不良提供了一条可持续的途径，且该方法需要与遗传进展和支持性农业政策相结合，以实现其长期成功。","Plant Science Today","2026-08-30T00:00:00Z",73,{"impact":83,"substance":247,"depth":83,"authority":81,"freshness":46,"relevant":21,"comment":248},22,"系统综述豆科作物农艺生物强化策略，对缓解隐性饥饿有重要参考价值，但时效性一般。",[250],{"name":243,"url":240},[252,27,253,254,255],"豆科作物","生物强化","微量元素","营养安全",{"code":32,"slug":33,"name":34,"path":35,"parent_code":36},[],{"status":39,"locked":40,"version":41,"method":42,"evidence":259},{"candidates":260,"agricultural_evidence":14},[261,265,272,276,282,287],{"code":32,"score":68,"supported":14,"title":262,"abstract":263,"tags":264},[],[49,33],[],{"code":266,"score":68,"supported":14,"title":267,"abstract":268,"tags":271},"I1",[],[269,270],"精准农业","precision agriculture",[],{"code":175,"score":46,"supported":14,"title":273,"abstract":274,"tags":275},[],[192],[],{"code":277,"score":46,"supported":14,"title":278,"abstract":279,"tags":281},"J1",[],[280],"农业政策",[],{"code":283,"score":21,"supported":40,"title":284,"abstract":285,"tags":286},"E2",[],[],[255],{"code":288,"score":21,"supported":40,"title":289,"abstract":290,"tags":291},"F2",[],[],[253],[293,294],"农业科技 微量元素 生物强化 营养安全","农业科技 微量元素","农业科技微量元素生物强化营养安全-1318","10.14719\u002Fpst.15686",{"doi":296,"openalex_id":298,"authors":299,"venue":243,"cited_by_count":147,"oa_url":318,"card":319,"direction":324,"ingested_from":154},"W7204727155",[300,303,306,309,312,315],{"name":301,"orcid":302},"R Vijayaprathipa","https:\u002F\u002Forcid.org\u002F0009-0001-4319-9641",{"name":304,"orcid":305},"T Parthipan","https:\u002F\u002Forcid.org\u002F0000-0002-6741-2857",{"name":307,"orcid":308},"T.

Gagnep., locally known as murta or patibet and also referred to by its synonym Clinogyne dichotoma, is a perennial mat-producing shrub traditionally cultivated in wetland and hilly regions of Bangladesh. Its cultivation has gained renewed interest for its potential contribution to climate-smart agriculture (CSA) through soil stabilisation, livelihood diversification, and ecological adaptability in fragile hill environments. This study aimed to evaluate the yield performance and economic returns of S. dichotoma cultivated across varying topographic elevations in the hilly Jhiri valleys of Bandarban, Bangladesh, and to assess its suitability as a climate-smart crop for sustainable hill farming systems. Approximately 500 rhizomes were planted in a 1700 sq. ft. experimental area divided into upper, middle, and lower elevation plots. Growth performance and yield-related data were collected annually from 2017 to 2021. Plant height and income generation were compared across elevation gradients to identify spatial variation and productivity trends. Variation in plant growth and income was observed across elevations. The lower plot exhibited comparatively better growth performance, characterised by taller plants and higher yield, which was attributed to enhanced soil moisture retention. Average annual incomes were BDT 558, BDT 1063, and BDT 1497 for the upper, middle, and lower plots, respectively, demonstrating an elevation-related yield pattern. Schumannianthus dichotoma showed its best observed performance under moist lower-slope conditions and exhibited adaptability to the hill tract environment. The crop’s low-input requirements, combined with its ecological benefits, support further evaluation of its inclusion in diversified hill farming systems. The findings indicate the potential of S. dichotoma as a climate-smart, resource-efficient alternative to conventional upland crops. Long-term studies integrating climatic parameters, hydrological monitoring, and soil health assessments are recommended to validate its contribution to resilience and sustainability in hilly agroecosystems.","Schumannianthus dichotoma（Roxb.）Gagnep.，当地俗称murta或patibet，亦以其异名Clinogyne dichotoma著称，是一种多年生、产席状地被的灌木，传统上栽培于孟加拉国的湿地和丘陵地区。因其在土壤稳固、生计多样化和脆弱丘陵环境中的生态适应性方面具有潜在贡献，其栽培近年来重新引起关注，被视为气候智能型农业（climate-smart agriculture, CSA）的可能组成部分。本研究旨在评估在孟加拉国班多尔班丘陵Jhiri山谷不同地形海拔条件下栽培S. dichotoma的产量表现和经济回报，并评价其作为气候智能型作物在可持续丘陵农业系统中的适宜性。在1700平方英尺的试验区内种植约500个根状茎，试验区分为高、中、低三个海拔地块。2017年至2021年间，每年收集生长表现和产量相关数据。比较不同海拔梯度下的株高和收入生成情况，以识别空间变异和生产力趋势。不同海拔间观察到植株生长和收入的差异。低海拔地块表现出相对较好的生长表现，其特征为植株较高、产量较大，这归因于较好的土壤水分保持能力。高、中、低地块的年均收入分别为558孟加拉塔卡（BDT）、1063 BDT和1497 BDT，显示出与海拔相关的产量格局。Schumannianthus dichotoma在湿润的低坡条件下表现最佳，并展现出对丘陵地带环境的适应性。该作物低投入需求及其生态效益，支持进一步评估其纳入多样化丘陵农业系统的可行性。研究结果表明，S. dichotoma具有作为传统高地作物替代品的潜力，是一种气候智能型、资源高效型作物。建议开展整合气候参数、水文监测和土壤健康评估的长期研究，以验证其对丘陵农业生态系统韧性和可持续性的贡献。","International Journal of Plant & Soil Science","2026-08-31T00:00:00Z",54,{"impact":336,"substance":83,"depth":184,"authority":13,"freshness":125,"relevant":21,"comment":337},8,"研究评估了孟加拉丘陵地区不同海拔下Schumannianthus dichotoma的生长与经济回报，为气候智慧农业提供参考，但时效性较低。",[339],{"name":332,"url":329},[341,27,342,343],"丘陵农业","气候智慧农业","孟加拉",{"code":32,"slug":33,"name":34,"path":35,"parent_code":36},[],{"status":39,"locked":40,"version":41,"method":42,"evidence":347},{"candidates":348,"agricultural_evidence":14},[349,353,359,364],{"code":32,"score":68,"supported":14,"title":350,"abstract":351,"tags":352},[],[49,33],[],{"code":354,"score":46,"supported":14,"title":355,"abstract":356,"tags":358},"H6",[],[357],"农业生态",[],{"code":266,"score":46,"supported":14,"title":360,"abstract":361,"tags":363},[],[362],"smart agriculture",[],{"code":201,"score":21,"supported":40,"title":365,"abstract":366,"tags":367},[],[],[342],[369,370],"气候智慧农业 丘陵农业 农业科技 孟加拉","气候智慧农业 丘陵农业","气候智慧农业丘陵农业农业科技孟加拉-1297","10.9734\u002Fijpss\u002F2026\u002Fv38i96295",{"doi":372,"openalex_id":374,"authors":375,"venue":332,"cited_by_count":147,"oa_url":329,"card":394,"direction":399,"ingested_from":154},"W7204800465",[376,378,380,382,384,387,389,391],{"name":377,"orcid":8},"Md.

Mulching can improve water productivity (WP) by reducing evaporation and stabilizing the soil microclimate. This study evaluated the effects of biodegradable mulch on irrigation efficiency, yield, and quality of processing tomato ( Solanum lycopersicum L.) under Mediterranean open-field conditions. Trial was conducted over two consecutive spring–summer seasons (2024–2025), at Portici, Southern Italy. Three mulching treatments: a paper mulch (PPR) and two biodegradable films (BM1, starch-polymer blend; BM2, copolyester), were compared with bare soil (BS, control). Soil volumetric water content and soil temperature were monitored to schedule irrigation and restore field capacity. Mulching, regardless of type, increased commercial yield in both years: +48% in 2024 and +24% in 2025 compared to BS, mainly due to higher fruit number. Mulched fruits showed greater firmness and higher °Brix values (+3–9%), although the latter was statistically significant only in the second year. Biodegradable films significantly increased ascorbic acid content (+46% vs. PPR), while PPR, due to its cooling effect, promoted a statistically significant lycopene (+52%) and carotenoids (+24%) content. Nitrogen content of fruits was lower under PPR (−26% in 2024; −3.6% in 2025). Moreover, mulching reduced water volumes and improved WP c , particularly in 2024 (PPR: 83.78 vs. BS: 48.80 kg m -3 ). Despite lower overall WP c in 2025, mulched plots maintained more stable efficiency. Biodegradable mulches could represent a sustainable alternative to polyethylene for Mediterranean processing tomato cultivation.","2026-08-27T00:00:00Z",64,{"impact":81,"substance":82,"depth":83,"authority":81,"freshness":125,"relevant":21,"comment":409},"研究证实可降解地膜在番茄种植中显著增产节水，为地中海地区可持续农业提供新数据。",[411],{"name":76,"url":404},[413,27,414,415,416],"智慧农业","节水灌溉","可降解地膜","番茄种植",{"code":104,"slug":418,"name":419,"path":420,"parent_code":421},"vegetables","蔬菜","\u002Ftopic\u002Fhorticulture\u002Fvegetables","B",[423],{"code":32,"slug":33,"name":34,"path":35,"parent_code":36},{"status":39,"locked":40,"version":41,"method":42,"evidence":425},{"candidates":426,"agricultural_evidence":14},[427,431,436,442],{"code":104,"score":81,"supported":14,"title":428,"abstract":429,"tags":430},[108],[108],[416],{"code":32,"score":432,"supported":14,"title":433,"abstract":434,"tags":435},11,[33],[33],[],{"code":437,"score":65,"supported":14,"title":438,"abstract":439,"tags":441},"H3",[],[440],"irrigation",[414],{"code":266,"score":21,"supported":40,"title":443,"abstract":444,"tags":445},[],[],[413],[447,448],"可降解地膜 农业科技 智慧农业 番茄种植","可降解地膜 农业科技","可降解地膜农业科技智慧农业番茄种植-1233","10.3389\u002Ffsufs.2026.1941196",{"doi":450,"openalex_id":452,"authors":453,"venue":76,"cited_by_count":147,"oa_url":475,"card":476,"direction":399,"ingested_from":154},"W7204487308",[454,457,460,463,466,469,472],{"name":455,"orcid":456},"Maria Eleonora Pelosi","https:\u002F\u002Forcid.org\u002F0009-0001-7483-7677",{"name":458,"orcid":459},"Lucia Ottaiano","https:\u002F\u002Forcid.org\u002F0000-0002-1596-203X",{"name":461,"orcid":462},"Ida Di Mola","https:\u002F\u002Forcid.org\u002F0000-0001-7259-5953",{"name":464,"orcid":465},"Eugenio Cozzolino","https:\u002F\u002Forcid.org\u002F0000-0002-5158-4072",{"name":467,"orcid":468},"Mohamed Houssemeddine Sellami","https:\u002F\u002Forcid.org\u002F0000-0002-7753-5703",{"name":470,"orcid":471},"Luca Vitale","https:\u002F\u002Forcid.org\u002F0000-0002-7637-264X",{"name":473,"orcid":474},"Mauro Mori","https:\u002F\u002Forcid.org\u002F0000-0003-3510-0901","https:\u002F\u002Fwww.frontiersin.org\u002Fjournals\u002Fsustainable-food-systems\u002Farticles\u002F10.3389\u002Ffsufs.2026.1941196\u002Fpdf",{"tldr":477,"method":478,"finding":479,"direction":399,"opportunity":480},"地中海条件下可降解地膜提高加工番茄产量、品质和水分生产率。","田间试验，比较纸膜、两种生物降解膜与裸土，监测土壤水分温度。","地膜增产24-48%，提高硬度、可溶性固形物，纸膜促番茄红素，生物膜增抗坏血酸。","可降解地膜与传感器结合，优化灌溉决策，研究不同作物和气候下的长期效应。","2026-09-01T04:03:08.933142Z",{"id":483,"title":484,"url":485,"summary":486,"summary_zh":487,"content":8,"source_name":488,"source_url":485,"published_at":489,"category":78,"cover_url":8,"hotness":13,"is_selected":40,"score":407,"score_detail":490,"sources":493,"tags":495,"primary_topic":500,"secondary_topics":501,"classification":508,"search_phrases":525,"slug":528,"view_count":147,"doi":529,"paper":530,"created_at":545},5583,"Active-Labeling Evaluation for Computer Agriculture Nematode-Cyst Detection Under Sparse Soil-Sample Ground Truth: An Artificial Intelligence Annotation-Efficiency Bound","https:\u002F\u002Fdoi.org\u002F10.5281\u002Fzenodo.23544145","Active learning promises to reduce the annotation burden of training nematode-cyst detection models for precision agriculture, but the size of that reduction is not known when ground truth comes from sparse soil samples rather than exhaustive visual inspection. the present analysis derives an annotation-efficiency bound for pool-based active learning under sparse soil-sample ground truth.
