This study evaluated LBS27, a novel Kappaphycus alvarezii -derived biostimulant, as a fertilizer-coating solution. In a replicated greenhouse pot experiment, we assessed the effects of LBS27-coated urea (LBS27-CU) on maize growth, plant nitrogen (N) content, and rhizosphere microbial communities during vegetative growth. Compared with uncoated urea, LBS27-CU significantly increased plant height, stem girth, leaf area, and biomass, as well as total flavonoid and phenolic contents. LBS27-CU also increased the relative abundance of plant-growth-promoting rhizosphere taxa, particularly Actinobacteria ( Rhodococcus ) and a nitrogen-fixing Rhizobium-clade genus. FAPROTAX-predicted functional profiles further indicated greater representation of bacteria associated with nitrogen fixation, nitrification, and ureolysis. These findings were consistent with soil microcosm assays, in which LBS27-CU degraded significantly faster than uncoated urea and showed greater early ammonium release. Despite this enhanced ureolytic potential, LBS27-CU reduced measured rhizosphere urease activity by 61% in the planted system, a paradox that our data suggest reflects accelerated plant nitrogen uptake and depletion of the ammonium substrate pool rather than direct enzymatic inhibition. LBS27-CU also increased rhizosphere β-glucosaminidase, arylsulfatase, and phosphatase activities, and upregulated root expression of the nitrogen transporter genes NPF6.6, NPF6.8, AMT1.1a, and AMT1.3. These changes were accompanied by higher glutamate dehydrogenase activity, total amino acid content and total tissue nitrogen content, indicating enhanced nitrogen assimilation. Collectively, these findings support LBS27-CU as a fertilizer-coating strategy that acts through a plant-dependent mechanism linking soil nitrogen cycling with accelerated nitrogen uptake, and plant growth.","过量使用无机肥料与土壤健康下降、微生物多样性降低和水质受损相关。本研究评估了LBS27——一种新型的源自麒麟菜（*Kappaphycus alvarezii*）的生物刺激素——作为肥料包膜溶液的效果。在重复的温室盆栽实验中，我们评估了LBS27包膜尿素（LBS27-CU）在营养生长期对玉米生长、植株氮（N）含量和根际微生物群落的影响。与未包膜尿素相比，LBS27-CU显著增加了株高、茎围、叶面积和生物量，以及总黄酮和酚类物质含量。LBS27-CU还提高了促进植物生长的根际类群的相对丰度，尤其是放线菌门（*Rhodococcus*）和一个固氮根瘤菌分支属。FAPROTAX预测的功能谱进一步表明，与固氮、硝化和尿素水解相关的细菌代表性更高。这些发现与土壤微宇宙实验一致，其中LBS27-CU的降解速度显著快于未包膜尿素，并表现出更高的早期铵释放。尽管尿素水解潜力增强，LBS27-CU在种植系统中使测得的根际脲酶活性降低了61%，我们的数据表明这一悖论反映的是植物氮吸收加速和铵底物池耗竭，而非直接的酶抑制。LBS27-CU还提高了根际β-氨基葡萄糖苷酶、芳基硫酸酯酶和磷酸酶活性，并上调了根系氮转运蛋白基因NPF6.6、NPF6.8、AMT1.1a和AMT1.3的表达。这些变化伴随着更高的谷氨酸脱氢酶活性、总氨基酸含量和总组织氮含量，表明氮同化增强。总体而言，这些发现支持LBS27-CU作为一种肥料包膜策略，其通过植物依赖机制将土壤氮循环与加速的氮吸收和植物生长联系起来。",null,"Frontiers in Sustainable Food Systems","2026-09-25T00:00:00Z","论文",10,false,73,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":21,"relevant":22,"comment":23},12,21,18,13,9,1,"海藻源生物刺激素包膜尿素提升玉米生长与氮利用的温室研究，方法扎实但属细分领域进展，产业影响有限。",[25],{"name":10,"url":6},[27,28,29,30,31],"玉米","生物刺激素","缓控释肥","土壤微生物","氮循环",{"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},[45,53,60,67,75],{"code":33,"score":19,"supported":46,"title":47,"abstract":48,"tags":52},true,[34],[49,50,34,51],"土壤","根际","rhizosphere",[30],{"code":54,"score":55,"supported":46,"title":56,"abstract":57,"tags":59},"A3",7,[],[27,58],"maize",[27],{"code":61,"score":55,"supported":46,"title":62,"abstract":63,"tags":66},"F3",[],[64,65],"肥料","fertilizer",[28],{"code":68,"score":69,"supported":46,"title":70,"abstract":71,"tags":74},"B7",6,[],[72,73],"温室","greenhouse",[],{"code":76,"score":77,"supported":46,"title":78,"abstract":79,"tags":81},"H6",3,[],[80],"生物多样性",[],[83,84],"Kappaphycus alvarezii 生物刺激素 尿素","LBS27 包膜尿素 玉米","Kappaphycusalvarezii生物刺激素尿素-3530","10.3389\u002Ffsufs.2026.1878004",{"doi":86,"openalex_id":88,"authors":89,"venue":10,"cited_by_count":101,"oa_url":6,"card":102,"direction":106,"ingested_from":108},"W7214285882",[90,92,94,97,99],{"name":91,"orcid":9},"Nivetha Nagarajan",{"name":93,"orcid":9},"Pushp Sheel Shukla",{"name":95,"orcid":96},"Sri Sailaja Nori","https:\u002F\u002Forcid.org\u002F0000-0002-5073-1368",{"name":98,"orcid":9},"Girish Tavarekere Rudrappa",{"name":100,"orcid":9},"Shrikumar Suryanarayan",0,{"tldr":103,"method":104,"finding":105,"direction":106,"opportunity":107},"用麒麟菜提取物LBS27包膜尿素，研究其对玉米生长、氮代谢和根际微生物的影响。","温室盆栽玉米，LBS27包膜尿素，测生长、氮含量、根际微生物及酶活。","LBS27-CU促生长、增氮吸收，富集促生菌，脲酶活性降61%因氮吸收加速。","农业绿色发展与碳","可探究海藻提取物包膜肥在不同土壤-作物系统的长期效应及微生物机制。","openalex","2026-09-26T23:30:07.502115Z",{"total":69,"page":22,"page_size":69,"items":111},[112,206,249,359,422,473],{"id":113,"title":114,"url":115,"summary":116,"summary_zh":117,"content":9,"source_name":10,"source_url":115,"published_at":118,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":119,"score_detail":120,"sources":124,"tags":126,"primary_topic":131,"secondary_topics":132,"classification":133,"search_phrases":177,"slug":180,"view_count":101,"doi":181,"paper":182,"created_at":205},5466,"Microbial and enzymatic response of soil to organic and natural management practices in chickpea-based cropping systems at the Satpura foothills","https:\u002F\u002Fdoi.org\u002F10.3389\u002Ffsufs.2026.1814274","Inroduction Natural and organic farming systems are increasingly recognized as sustainable agroecological approaches that promote regenerative practices, ecological balance, and reduced reliance on external inputs. This study aimed to assess the effects of different nutrient management strategies on the soil enzymatic and biological properties of chickpea-based cropping systems. Methods A field experiment was conducted during the rabi seasons of 2022–23 and 2023–24 at the Centre for Organic Agriculture Research and Training, Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra, India. The experiment followed a strip-plot design with four replications. Four cropping systems were evaluated in a 2:2 row proportion: sole chickpea, chickpea intercropped with coriander, chickpea intercropped with linseed, and chickpea intercropped with sorghum. Three nutrient management strategies were assessed: organic farming, natural farming, and an integrated approach combining organic and natural farming inputs. Results Across both years, sole chickpea consistently supported greater soil biological activity than the intercropping systems. Compared with chickpea–sorghum intercropping under natural farming, sole chickpea managed using integrated organic and natural farming practices significantly increased soil nitrogen, phosphorus, and potassium by 60%, 100%, and 192%, respectively. Fungal, bacterial, and actinomycete populations increased by 78.0%, 85.4%, and 109.8%, respectively. Soil microbial biomass carbon and nitrogen increased by 42.4% and 64.6%, respectively. Urease, dehydrogenase, acid phosphatase, and alkaline phosphatase activities increased by 75.6%, 100%, 116.8%, and 42.4%, respectively. Among the nutrient management strategies, the integrated application of organic and natural farming inputs showed superior performance in improving soil biological properties compared with either approach alone. Discussion The findings indicate that sole chickpea combined with integrated organic and natural nutrient management can improve soil microbial populations, enzymatic activities, nutrient availability, and overall soil biological health. This management strategy may contribute to long-term soil fertility and sustainable agricultural production in Inceptisols of the Satpura foothill region of India under semi-arid conditions.","引言 自然农业与有机农业体系日益被视为可持续的农业生态方法，能够促进再生性实践、生态平衡并减少对外部投入的依赖。本研究旨在评估不同养分管理策略对鹰嘴豆（chickpea）种植体系土壤酶学及生物学特性的影响。方法 于2022—23年度和2023—24年度rabi季在印度马哈拉施特拉邦阿科拉市Dr. Panjabrao Deshmukh Krishi Vidyapeeth农学系有机农业研究与培训中心开展田间试验。试验采用条区设计（strip-plot design），设4次重复。以2：2行比评估4种种植体系：鹰嘴豆单作、鹰嘴豆与芫荽间作、鹰嘴豆与亚麻间作、鹰嘴豆与高粱间作。评估3种养分管理策略：有机农业、自然农业以及有机与自然农业投入相结合的集成方式。结果 两年间，鹰嘴豆单作始终较间作体系支持更高的土壤生物学活性。与自然农业下的鹰嘴豆—高粱间作相比，采用有机与自然农业集成实践的鹰嘴豆单作使土壤氮、磷、钾分别显著提高60%、100%和192%；真菌、细菌和放线菌数量分别增加78.0%、85.4%和109.8%；土壤微生物生物量碳和氮分别增加42.4%和64.6%；脲酶、脱氢酶、酸性磷酸酶和碱性磷酸酶活性分别提高75.6%、100%、116.8%和42.4%。在养分管理策略中，有机与自然农业投入的集成施用较任一单一方式在改善土壤生物学特性方面表现更优。讨论 研究结果表明，鹰嘴豆单作结合有机与自然养分集成管理可改善土壤微生物种群、酶活性、养分有效性及整体土壤生物学健康。该管理策略可能有助于印度萨特普拉山麓地区半干旱条件下始成土（Inceptisols）的长期土壤肥力和可持续农业生产。","2026-10-20T00:00:00Z",69,{"impact":13,"substance":121,"depth":122,"authority":20,"freshness":21,"relevant":22,"comment":123},20,17,"田间试验数据扎实、结论明确，但属印度区域尺度的农学论文，对国内智慧农业主题页聚合价值有限，可作国际有机农业参考。",[125],{"name":10,"url":115},[127,128,129,30,130],"间作系统","有机农业","养分管理","鹰嘴豆",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[],{"status":40,"locked":14,"version":41,"method":42,"evidence":134},{"candidates":135,"agricultural_evidence":46},[136,141,148,155,160,166,171],{"code":33,"score":137,"supported":46,"title":138,"abstract":139,"tags":140},15,[34],[49,34],[30],{"code":142,"score":69,"supported":46,"title":143,"abstract":144,"tags":147},"A5",[],[145,146],"高粱","sorghum",[],{"code":149,"score":69,"supported":46,"title":150,"abstract":151,"tags":154},"A7",[],[152,153],"间作","intercropping",[],{"code":61,"score":156,"supported":46,"title":157,"abstract":158,"tags":159},4,[],[129],[129],{"code":161,"score":156,"supported":46,"title":162,"abstract":163,"tags":165},"H8",[],[164],"可持续农业",[128],{"code":76,"score":77,"supported":46,"title":167,"abstract":168,"tags":170},[],[169],"农业生态",[],{"code":172,"score":77,"supported":46,"title":173,"abstract":174,"tags":176},"H7",[],[175],"干旱",[],[178,179],"鹰嘴豆 有机农业 土壤微生物","Satpura 鹰嘴豆 间作","鹰嘴豆有机农业土壤微生物-5466","10.3389\u002Ffsufs.2026.1814274",{"doi":181,"openalex_id":183,"authors":184,"venue":10,"cited_by_count":101,"oa_url":199,"card":200,"direction":106,"ingested_from":108},"W7223012759",[185,187,189,191,193,195,197],{"name":186,"orcid":9},"Nalla Charitha",{"name":188,"orcid":9},"Adinath N.

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",{"impact":367,"substance":18,"depth":122,"authority":20,"freshness":259,"relevant":22,"comment":368},14,"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。",[370],{"name":10,"url":362},[27,223,372,373,374],"养分利用效率","磷肥减量","微生物菌剂",{"code":54,"slug":58,"name":27,"path":228,"parent_code":229},[377],{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},{"status":40,"locked":14,"version":41,"method":42,"evidence":379},{"candidates":380,"agricultural_evidence":46},[381,385,389],{"code":54,"score":137,"supported":46,"title":382,"abstract":383,"tags":384},[58],[27,58],[27],{"code":33,"score":137,"supported":46,"title":386,"abstract":387,"tags":388},[34],[49,34],[223],{"code":61,"score":156,"supported":46,"title":390,"abstract":391,"tags":392},[],[129],[372],[394,395],"低品位磷矿粉

are valuable tools for agricultural monitoring. However, the need for many input parameters, the uncertainties related to model parametrization and structure, and the lack of spatial information motivate the application of techniques such as data assimilation (DA). This paper proposes a DA framework to improve maize biomass estimation. A particle filter (PF) was used to assimilate remotely sensed reflectance and soil moisture (SM) data, both independently and simultaneously, into the Agricultural Production Systems sIMulator (APSIM) model. Reflectance observations from Sentinel-2 were assimilated through coupling APSIM with the radiative transfer model (RTM) PROSAIL, while SMAP L-band SM products were directly assimilated into APSIM. The synthetic experiment, designed to evaluate the reliability of the proposed procedure, highlighted the strength of assimilating reflectance to constrain crop traits and of SM to provide complementary information on crop water status and to contribute to more robust ensemble trajectories. Real-case results confirmed these findings. DA assimilation of SM proved valuable particularly under data gaps and drought conditions. Although it did not consistently surpass single-source assimilation strategies, the joint assimilation yielded consistent results, especially in 2023, where RMSE, nRMSE and bias were 1258.83 kg\u002Fha, 16.62%, and - 220.52 kg\u002Fha, respectively. The proposed framework demonstrates the potential of multi-source DA to enhance biomass estimation and support robust, spatially explicit crop monitoring.","作物生长模型（CGM）是农业监测的重要工具。然而，其对大量输入参数的需求、模型参数化与结构相关的不确定性以及空间信息的缺乏，推动了数据同化（DA）等技术的应用。本文提出了一种数据同化框架，以改进玉米生物量估算。采用粒子滤波（PF）将遥感反射率和土壤水分（SM）数据分别独立及同时同化进入农业生产系统模拟器（APSIM）模型。Sentinel-2反射率观测数据通过将APSIM与辐射传输模型（RTM）PROSAIL耦合进行同化，而SMAP L波段土壤水分产品则直接同化进入APSIM。为评估所提方法可靠性而设计的合成实验，凸显了同化反射率在约束作物性状方面的优势，以及同化土壤水分在提供作物水分状况补充信息和促进更稳健集合轨迹方面的作用。实际案例结果证实了这些发现。土壤水分数据同化在数据缺失和干旱条件下尤为有价值。尽管联合同化未能持续超越单源同化策略，但其结果具有一致性，尤其在2023年，RMSE、nRMSE和偏差分别为1258.83 kg\u002Fha、16.62%和-220.52 kg\u002Fha。所提出的框架展示了多源数据同化在增强生物量估算和支持稳健、空间显式作物监测方面的潜力。","Precision Agriculture",82,{"impact":19,"substance":217,"depth":482,"authority":367,"freshness":21,"relevant":22,"comment":483},19,"将Sentinel-2反射率与SMAP土壤水分同化进APSIM模型估算玉米生物量，方法新颖、结论可靠，对作物遥感监测有参考价值。",[485],{"name":479,"url":476},[487,27,488,264,489],"智慧农业","作物模型","数据同化",{"code":54,"slug":58,"name":27,"path":228,"parent_code":229},[492],{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},{"status":40,"locked":14,"version":41,"method":42,"evidence":494},{"candidates":495,"agricultural_evidence":46},[496,500,504,509,513,518,523],{"code":54,"score":137,"supported":46,"title":497,"abstract":498,"tags":499},[58],[27,58],[27],{"code":33,"score":367,"supported":46,"title":501,"abstract":502,"tags":503},[34],[49,34],[],{"code":172,"score":69,"supported":46,"title":505,"abstract":506,"tags":508},[],[175,507],"drought",[],{"code":292,"score":156,"supported":46,"title":510,"abstract":511,"tags":512},[],[295],[264],{"code":514,"score":22,"supported":14,"title":515,"abstract":516,"tags":517},"I1",[],[],[487],{"code":519,"score":22,"supported":14,"title":520,"abstract":521,"tags":522},"I2",[],[],[488],{"code":524,"score":22,"supported":14,"title":525,"abstract":526,"tags":527},"I5",[],[],[489],[529,530],"Sentinel-2 SMAP APSIM 玉米生物量","多源数据同化 玉米 遥感","Sentinel-2SMAPAPSIM玉米生物量-3525","10.1007\u002Fs11119-026-10442-6",{"doi":532,"openalex_id":534,"authors":535,"venue":479,"cited_by_count":101,"oa_url":476,"card":559,"direction":356,"ingested_from":108},"W7214405444",[536,538,541,544,547,549,551,554,556],{"name":537,"orcid":9},"Manuela Montella",{"name":539,"orcid":540},"Christian Bossung","https:\u002F\u002Forcid.org\u002F0000-0003-4651-2645",{"name":542,"orcid":543},"Thanh Huy Nguyen","https:\u002F\u002Forcid.org\u002F0000-0003-2471-350X",{"name":545,"orcid":546},"Marco Chini","https:\u002F\u002Forcid.org\u002F0000-0002-9094-0367",{"name":548,"orcid":9},"Jean François Iffly",{"name":550,"orcid":9},"Thomas Udelhoven",{"name":552,"orcid":553},"Julia Kubanek","https:\u002F\u002Forcid.org\u002F0000-0001-9597-2029",{"name":555,"orcid":9},"Zoltan Szantoi",{"name":557,"orcid":558},"Miriam Machwitz","https:\u002F\u002Forcid.org\u002F0000-0002-4999-673X",{"tldr":560,"method":561,"finding":562,"direction":356,"opportunity":563},"将Sentinel-2反射率与SMAP土壤水分同化进APSIM模型，提升玉米生物量估算精度。","粒子滤波同化Sentinel-2反射率（经PROSAIL耦合）与SMAP土壤水分","联合同化结果稳健，2023年RMSE为1258.83 kg\u002Fha，nRMSE 16.62%，偏差-2","可探索多源数据同化在数据缺失与干旱条件下的自适应权重策略，并推广至其他作物与区域。","2026-09-26T23:30:03.247019Z"]
