Despite the novelty of soil testing in enhancing agricultural productivity, adoption remains limited. Therefore, this study was conducted to identify the factors influencing smallholder maize farmers’ decision to conduct soil testing in western Kenya. The study used descriptive statistics to summarize the data, and a logistic regression model on a sample of 1,592 to evaluate the determinants of soil testing among farmers. Descriptive statistics show that less than 8% of farmers had conducted soil tests on their farms, and about 7% knew where to obtain soil testing services. The logistic results show that access to extension services ( p \u003C 0.01), age of the household head ( p \u003C 0.01), group membership ( p \u003C 0.01), farmers’ awareness about where to obtain soil testing services ( p \u003C 0.05), land size ( p \u003C 0.05), perceived fertility of the soil ( p \u003C 0.05), economically active household members ( p \u003C 0.10) are statistically significant in influencing the decision to conduct soil testing.

This exploratory qualitative study examined smallholder farmers’ lived experiences of FAW damage in hybrid and local maize in Siaya County, Kenya. Face-to-face semi-structured interviews lasting 30–45 min were conducted with 88 purposively selected farmers, and responses were analyzed thematically by two independent researchers. Farmers described FAW as recurrent and difficult to control; 43.2% reported infestation every season. Most participants (77.3%) perceived hybrid maize as more severely affected than local maize, whereas 9.1% perceived local maize as more affected and 9.1% reported similar effects. Participants associated infestation with reduced yields, impaired crop growth, lower-quality harvests, lost income, pesticide and labour costs, depleted maize stocks, food purchases, and stress related to financial and food uncertainty. Reported responses included pesticide use, repeated spraying, purchasing food, crop diversification, and reconsidering maize varieties. Because the study relied on farmers’ accounts rather than controlled varietal comparisons, the perceived differences cannot be attributed to seed characteristics independently of management and growing conditions. The findings indicate that farmers evaluate FAW damage through interconnected production, livelihood, food-security, and seed-choice concerns, supporting locally tested pest-management and seed advisory services.","草地贪夜蛾（Fall Armyworm, FAW）是撒哈拉以南非洲以玉米为基础的粮食系统面临的持续威胁，但人们对农民在不同种子类型和家庭生计条件下如何经历其影响知之甚少。本探索性定性研究考察了肯尼亚西亚亚县小农户在杂交玉米和本地玉米中遭受草地贪夜蛾危害的生活体验。研究对88名有意选取的农民进行了为期30至45分钟的面对面半结构化访谈，并由两名独立研究人员对回答进行主题分析。农民将草地贪夜蛾描述为反复发生且难以控制；43.2%报告每季均发生虫害。大多数参与者（77.3%）认为杂交玉米比本地玉米受害更严重，而9.1%认为本地玉米受害更严重，9.1%报告两者影响相似。参与者将虫害与产量下降、作物生长受损、收成品质量降低、收入损失、农药和劳动力成本、玉米库存耗尽、粮食购买以及与经济和粮食不确定性相关的压力联系起来。报告的应对措施包括使用农药、反复喷药、购买粮食、作物多样化以及重新考虑玉米品种。由于本研究依赖农民叙述而非受控品种比较，所感知的差异不能独立于管理和生长条件而归因于种子特征。研究结果表明，农民通过生产、生计、粮食安全和种子选择等相互关联的关注来评估草地贪夜蛾危害，这支持开展本地化测试的害虫管理和种子咨询服务。","2026-10-02T00:00:00Z",65,{"impact":119,"substance":17,"depth":120,"authority":121,"freshness":12,"relevant":20,"comment":122},8,16,13,"基于88户肯尼亚小农户访谈的质性研究，揭示草地贪夜蛾对杂交与本地玉米影响的农户感知差异，对非洲玉米病虫害防控与种子推广有参考价值，但属区域案例、公共影响有限。",[124],{"name":9,"url":113},[126,127,32,25,128],"种业振兴","粮食安全","病虫害防治",{"code":30,"slug":31,"name":32,"path":33,"parent_code":34},[131],{"code":37,"slug":38,"name":39,"path":40,"parent_code":41},{"status":49,"locked":13,"version":50,"method":51,"evidence":133},{"candidates":134,"agricultural_evidence":55},[135,140,144,151,157],{"code":30,"score":136,"supported":55,"title":137,"abstract":138,"tags":139},15,[31],[32,31],[32],{"code":37,"score":136,"supported":55,"title":141,"abstract":142,"tags":143},[57],[25,57],[25],{"code":145,"score":108,"supported":55,"title":146,"abstract":147,"tags":150},"F4",[],[148,149],"农药","pesticide",[],{"code":152,"score":153,"supported":55,"title":154,"abstract":155,"tags":156},"A8",4,[],[127],[127],{"code":158,"score":20,"supported":13,"title":159,"abstract":160,"tags":161},"F1",[],[],[126],[163,164],"肯尼亚 草地贪夜蛾 玉米","杂交玉米 本地玉米 虫害","肯尼亚草地贪夜蛾玉米-3989","10.3389\u002Ffsufs.2026.1925312",{"doi":166,"openalex_id":168,"authors":169,"venue":9,"cited_by_count":97,"oa_url":113,"card":180,"direction":103,"ingested_from":105},"W7215042180",[170,173,175,177],{"name":171,"orcid":172},"George Ariya","https:\u002F\u002Forcid.org\u002F0000-0003-2286-9455",{"name":174,"orcid":8},"Beatrice Cheserek",{"name":176,"orcid":8},"Violet Kadenyeka Mugalavai",{"name":178,"orcid":179},"Lizzy A.

朱虹**\n\n暮秋的黑龙江省安达市天高云淡，一垄垄盐碱旱田刚翻过土，泛着浅浅的白霜。10月13日，记者跟随黑龙江省农科院草业研究所研究员林红，穿过连片田块，走进安达绿生源现代养殖场。还没进牛舍，一股青贮特有的酸香就扑面而来。黑白花奶牛次第低头，把脑袋埋进食槽，咀嚼声此起彼伏。饲养员抄起一捧青贮料，深绿的茎叶裹着饱满的籽粒，“这就是咱们的‘龙育15’‘龙育17’。”\n\n![Image

low-grade rock phosphate enhances maize productivity and phosphorus availability in contrasting soil orders","https:\u002F\u002Fdoi.org\u002F10.3389\u002Ffsufs.2026.1982290","Introduction Efficient phosphorus (P) management is essential for improving crop productivity while reducing dependence on energy-intensive, highly soluble P fertilisers. 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":197,"substance":296,"depth":297,"authority":121,"freshness":119,"relevant":20,"comment":298},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。",[300],{"name":9,"url":290},[32,264,302,303,304],"养分利用效率","磷肥减量","微生物菌剂",{"code":30,"slug":31,"name":32,"path":33,"parent_code":34},[307],{"code":43,"slug":44,"name":45,"path":46,"parent_code":47},{"status":49,"locked":13,"version":50,"method":51,"evidence":309},{"candidates":310,"agricultural_evidence":55},[311,315,319],{"code":30,"score":136,"supported":55,"title":312,"abstract":313,"tags":314},[31],[32,31],[32],{"code":43,"score":136,"supported":55,"title":316,"abstract":317,"tags":318},[44],[276,44],[264],{"code":320,"score":153,"supported":55,"title":321,"abstract":322,"tags":324},"F3",[],[323],"养分管理",[302],[326,327],"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","2026-09-25T00:00:00Z",82,{"impact":17,"substance":259,"depth":413,"authority":197,"freshness":198,"relevant":20,"comment":414},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。",[416],{"name":409,"url":406},[418,32,419,420,421],"智慧农业","作物模型","遥感监测","数据同化",{"code":30,"slug":31,"name":32,"path":33,"parent_code":34},[424],{"code":43,"slug":44,"name":45,"path":46,"parent_code":47},{"status":49,"locked":13,"version":50,"method":51,"evidence":426},{"candidates":427,"agricultural_evidence":55},[428,432,436,443,449,454,459],{"code":30,"score":136,"supported":55,"title":429,"abstract":430,"tags":431},[31],[32,31],[32],{"code":43,"score":197,"supported":55,"title":433,"abstract":434,"tags":435},[44],[276,44],[],{"code":437,"score":108,"supported":55,"title":438,"abstract":439,"tags":442},"H7",[],[440,441],"干旱","drought",[],{"code":444,"score":153,"supported":55,"title":445,"abstract":446,"tags":448},"I3",[],[447],"遥感",[420],{"code":450,"score":20,"supported":13,"title":451,"abstract":452,"tags":453},"I1",[],[],[418],{"code":455,"score":20,"supported":13,"title":456,"abstract":457,"tags":458},"I2",[],[],[419],{"code":460,"score":20,"supported":13,"title":461,"abstract":462,"tags":463},"I5",[],[],[421],[465,466],"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":468,"openalex_id":470,"authors":471,"venue":409,"cited_by_count":97,"oa_url":406,"card":495,"direction":499,"ingested_from":105},"W7214405444",[472,474,477,480,483,485,487,490,492],{"name":473,"orcid":8},"Manuela Montella",{"name":475,"orcid":476},"Christian Bossung","https:\u002F\u002Forcid.org\u002F0000-0003-4651-2645",{"name":478,"orcid":479},"Thanh Huy Nguyen","https:\u002F\u002Forcid.org\u002F0000-0003-2471-350X",{"name":481,"orcid":482},"Marco Chini","https:\u002F\u002Forcid.org\u002F0000-0002-9094-0367",{"name":484,"orcid":8},"Jean François Iffly",{"name":486,"orcid":8},"Thomas Udelhoven",{"name":488,"orcid":489},"Julia Kubanek","https:\u002F\u002Forcid.org\u002F0000-0001-9597-2029",{"name":491,"orcid":8},"Zoltan Szantoi",{"name":493,"orcid":494},"Miriam Machwitz","https:\u002F\u002Forcid.org\u002F0000-0002-4999-673X",{"tldr":496,"method":497,"finding":498,"direction":499,"opportunity":500},"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","农业遥感与作物表型","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"]
