Nature-based biodiversity agriculture is currently recognized as the best path for green agriculture. Agricultural systems with biodiversity can provide ecological functions such as pest and greenhouse gas emission control, water and nutrient regulation, pollination, etc. How to construct a healthy agricultural biodiversity system and make it play a beneficial role for green agriculture is an urgent issue that needs attention. Thus, this study summarizes traditional biodiversity utilization and cultivation techniques and their comprehensive effects. Results showed that paddy rotation modes improved rice yield and enhanced soil fertility indicators such as soil organic matter (SOC), total nitrogen (TN), available phosphorus (AP), and available potassium (AK). Paddy co-culture modes effectively suppressed major pests and diseases, including rice planthopper, rice leaf roller, rice blast, and weeds, with reductions ranging from 15.5 % to 73.9 %. Organic fertilization and straw returning practices increased microbial diversity, as evidenced by the rise in bacterial (1.9 %–7.5 %) and fungal (6.5 %–24.1 %) Shannon index. Based on these findings, this study identifies three key challenges in promoting agricultural biodiversity in modern intensive farming: efficiency in human resource utilization, integration of functions, and adaptation to environmental heterogeneity. And then proposed the “four zones” strategies including production functional zone, production and ecological service combined functional zone, production service and ecological service combined functional zone, and ecological service functional zone. As a conclusion, the study highlights that the rational spatial configuration and species combination of these zones under diverse climatic and land-use conditions is essential for achieving the dual goals of ecological sustainability and economic viability, and should be a key focus for future research and practice.

以自然为基础的生物多样性农业是目前公认的绿色农业的最佳途径。具有生物多样性的农业系统可以提供有害生物和温室气体排放控制、水和养分调节、授粉等生态功能。如何构建健康的农业生物多样性系统，使其在绿色农业中发挥有益作用，是一个迫切需要关注的问题。因此，本研究总结了传统生物多样性利用与培育技术及其综合效果。结果表明，水稻轮作模式提高了水稻产量，提高了土壤有机质（SOC）、全氮（TN）、速效磷（AP）和速效钾（AK）等土壤肥力指标。水稻共栽模式对稻飞虱、稻卷叶螟、稻瘟病、杂草等主要病虫害的防治效果显著，减少幅度在15.5% ~ 73.9%之间。有机肥和秸秆还田增加了土壤微生物多样性，细菌Shannon指数（1.9% ~ 7.5%）和真菌Shannon指数（6.5% ~ 24.1%）增加。基于这些发现，本研究确定了现代集约农业促进农业生物多样性的三个关键挑战：人力资源利用效率、功能整合和对环境异质性的适应。进而提出了生产功能区、生产与生态服务结合功能区、生产与生态服务结合功能区、生态服务功能区的“四区”战略。研究结果表明，在不同的气候和土地利用条件下，合理的空间配置和物种组合对实现生态可持续性和经济可行性的双重目标至关重要，应成为未来研究和实践的重点。

The pH of the rhizosphere strongly regulates nutrient transformations, microbial activity, and plant hormone metabolism in agroecosystems, thereby shaping crop growth, stress tolerance, and yield. Yet a global synthesis quantifying the magnitude, direction, and drivers of rhizosphere effects on soil pH has been lacking. To address this gap, we conducted a meta-analysis incorporating 906 individual cases of the rhizosphere effect on soil pH extracted from 102 peer-reviewed studies, along with associated biotic and abiotic variables across global agricultural ecosystems. Overall, the rhizosphere effect significantly decreased in soil pH by 1.04 % ± 0.20 %, but the effect varied with climate, management, crop identity, and soil properties. Specifically, the rhizosphere effect reduced soil pH by 1.34 % ± 0.10 % in arid areas (aridity index <0.65), while showing no significant change (ranging from −0.26 % to 0.08 %) in humid areas (aridity index >0.65). This arid humid contrast likely reflects differences in initial alkalinity/buffering and the balance of plant–microbial processes. Beyond climatic, the pH lowering effect of the rhizosphere was more pronounced in soils with an initial pH of 6.5–7.5 and soil organic carbon content of 10–20 g kg⁻¹. Among crops, soybean showed the largest decreases (arid: 3.00 % ± 0.43 %; humid: 1.73 % ± 0.34 %). Moreover, in humid areas, soil nutrient availability and microbial communities/functions were more sensitive to rhizosphere-induced pH shifts than in arid regions. Collectively, these findings highlight the potential for agricultural practices, particularly soybean cultivation in arid regions, to contribute substantially to global scale acidification, especially in soils with near neutral pH.

根际pH值强烈调节农业生态系统中的养分转化、微生物活动和植物激素代谢，从而影响作物生长、抗逆性和产量。然而，目前还缺乏量化根际对土壤pH影响的幅度、方向和驱动因素的全球综合研究。为了解决这一差距，我们进行了一项荟萃分析，纳入了从102项同行评审研究中提取的906例根际对土壤pH值的影响，以及全球农业生态系统中相关的生物和非生物变量。总体而言，根际效应显著降低了土壤pH值（1.04%±0.20%），但影响因气候、管理、作物特性和土壤性质而异。在干旱地区（干旱指数>；0.65），根际效应使土壤pH值降低了1.34%±0.10%，而在湿润地区（干旱指数>；0.65），根际效应对土壤pH值没有显著影响（变化范围为- 0.26% ~ 0.08%）。这种干旱潮湿的对比可能反映了初始碱度/缓冲和植物-微生物过程平衡的差异。除气候因素外，当土壤初始pH为6.5 ~ 7.5，土壤有机碳含量为10 ~ 20 g kg−1时，根际土壤的pH降低作用更为明显。在作物中，大豆的降幅最大（干旱：3.00 %±0.43%；湿润：1.73%±0.34%）。此外，湿润地区土壤养分有效性和微生物群落/功能对根际pH值变化的敏感性高于干旱区。总的来说，这些发现突出了农业实践的潜力，特别是干旱地区的大豆种植，对全球范围的酸化做出了重大贡献，特别是在pH值接近中性的土壤中。

The arid regions of Northwest China are facing significant challenges in agriculture. Optimizing crop configuration contributes to improved environmental stewardship under the Water-Energy-Food Nexus framework, but economic viability of such systems remains to be quantified. Here, we proposed and implemented an extended Water-Energy-Food-Economy (WEFE) Nexus model to optimize the trade-offs between productivity, ecological sustainability and economic viability in Northwest China. We evaluated the WEFE Nexus of crop production in Wensu County, Xinjiang Uygur Autonomous Region from 2004 to 2023, and optimized crop configuration under four scenario considering wheat planting policy relaxation and technological advancements. During the study years, the agricultural energy consumption, grain production, production value, and production efficiency have increased by 87 %, 146 %, 384 %, and 69 % respectively, reflecting complex crop-policy-market-technology interplay. Under the scenario combining improved irrigation technology with relaxed wheat planting policy, the WEFE Nexus indicators showed potential improvements of 10–40 %. With an equilibrium solution, the grain production increased by 33 %, production value by 5 %, production efficiency by 13 %, and irrigation water requirement and energy consumption reduced by 2 % and 0.2 %. We suggest that the model effectively optimizes management across multiple indicators. Economic benefits and the extent of technology adoption have led farmers to favor cotton and maize, while the government has mandated wheat planting areas through policy. Our results identified equilibrium strategies for agricultural sustainability in Northwest China. These include improving wheat irrigation efficiency, maintaining cotton areas, and replacing wheat with maize and rice.

中国西北干旱地区的农业面临着重大挑战。在水-能源-粮食关系框架下，优化作物配置有助于改善环境管理，但这种系统的经济可行性仍有待量化。本文提出并实施了一个扩展的水-能源-食物-经济（WEFE） Nexus模型，以优化西北地区生产力、生态可持续性和经济可行性之间的权衡。本文对新疆温宿县2004 - 2023年作物生产的WEFE Nexus进行了评价，并在考虑小麦种植政策放宽和技术进步的4种情景下对作物配置进行了优化。研究年间，农业能源消耗、粮食产量、产值和生产效率分别增长了87%、146%、384%和69%，反映出作物-政策-市场-技术复杂的相互作用。在改良灌溉技术与放宽小麦种植政策相结合的情景下，WEFE Nexus指标有10 ~ 40%的改善潜力。在均衡溶液条件下，粮食产量提高33%，产值提高5%，生产效率提高13%，灌溉需水量和能耗分别降低2%和0.2%。我们认为，该模型有效地优化了跨多个指标的管理。经济效益和技术采用的程度使农民青睐棉花和玉米，而政府通过政策规定了小麦种植面积。研究结果确定了西北地区农业可持续发展的均衡策略。这些措施包括提高小麦灌溉效率，维持棉花种植面积，以及用玉米和水稻代替小麦。

Plantains are plants of the genus Musa that require substantial amounts of nutrients applied to the soil, highlighting nitrogen (N), phosphorus (P₂O₅) and potassium (K₂O) as being the most critical. This nutrient demand is often unmet in the acidic soil, highly weathered and presenting low natural fertility. Mineral fertilizers are used to correct deficiencies in soil nutrients and enhance crop productivity. Establishing optimal application rates is essential for the success and sustainability of agricultural systems. This research aimed to evaluate the effects of different fertilization rates of N, P₂O₅ and K₂O on the parameters of growth, development, and productivity of ‘Terra Maranhão’ plantain in Brazil. Seventeen combinations of N (0–700 kg ha⁻¹), P₂O₅ (0–450 kg ha⁻¹) and K₂O (0–1370 kg ha⁻¹) were assessed. The design used was randomized blocks with three replications, each plot consisting of 10 plants. Data were subjected to regression analysis, which tested polynomial and linear univariate models. Fertilization with N, P₂O₅ and K₂O significantly influenced the growth, development and productivity parameters, fitting quadratic or linear univariate models. The quadratic models showed maximum physical efficiency rates for the productivity parameters ranging from 430 to 513 kg ha⁻¹ of N (p < 0.001), 281–285 kg ha⁻¹ of P₂O₅ (p < 0.001), and 723–868 kg ha⁻¹ of K₂O (p = 0.001 to p < 0.001), resulting in a bunch mass of 45.9–46.2 kg, average hand mass of 4.12–4.13 kg, and productivity of 61–62 t ha⁻¹. Plants with a pseudostem circumference of 95 cm, pseudostem height of 4.5 m and 16 leaves per plant presented productivity greater than 65 t ha⁻¹. These findings contribute to the optimization of the ‘Terra Maranhão’ plantain production system, providing recommendations for fertilization rates of N, P₂O₅ and K₂O that maximize productivity in a shorter production cycle.

车前草是芭蕉属植物，需要大量的养分施用于土壤，其中氮(N)、磷（P2O5）和钾（K2O）是最关键的。这种养分需求在酸性土壤中往往得不到满足，因为酸性土壤风化严重，自然肥力较低。矿质肥料用于纠正土壤养分不足，提高作物生产力。确定最佳施用量对农业系统的成功和可持续性至关重要。本研究旨在评价不同施氮量、P2O5和K2O对巴西‘Terra maranh’大蕉生长发育和生产力参数的影响。对N （0 ~ 700 kg ha−1）、P2O5 （0 ~ 450 kg ha−1）和K2O （0 ~ 1370 kg ha−1）的17种组合进行了评估。采用随机区组设计，每组3个重复，每个小区包括10株植物。数据进行回归分析，检验多项式和线性单变量模型。N、P2O5和K2O对生长发育和生产力参数影响显著，拟合二次或线性单变量模型。二次模型显示，在N （p < 0.001）、P2O5 （p < 0.001）和K2O （p = 0.001 ~ p < 0.001）的生产参数范围内，最大物理效率为430 ~ 513 kg ha - 1， P2O5 （p < 0.001）和K2O (p = 0.001 ~ p < 0.001)，导致束质量为45.9 ~ 46.2 kg，平均手质量为4.12 ~ 4.13 kg，生产率为61 ~ 62 t ha - 1。假茎周长为95 cm、假茎高为4.5 m、单株16片叶片的植株产量大于65 tha−1。这些发现有助于“Terra maranh o”大蕉生产系统的优化，为在较短的生产周期内实现产量最大化提供N、P2O5和K2O的施肥量建议。

Maize production per hectare in Southwest Nigeria ranks among the lowest compared to other regions worldwide. Digital methodologies focusing on soil fertility determinants and geographic data were used to evaluate land suitability. We explored a methodology that combined ordinal logistic regression with continuous soil characteristic modeling in a two-step mapping approach to assess land suitability. A stepwise forward regression analysis was performed on environmental variables to identify those that significantly influenced the outcomes at a 95 % confidence level (p < 0.05). Most areas in the region, from the north to the south, had organic carbon concentrations below 1 %. In the northern part, a significant portion showed total nitrogen levels below 0.1 g kg⁻¹. The majority of the area had exchangeable phosphorus levels ranging from 23 to 28 mg kg⁻¹, while some eastern locations had extractable potassium levels above 0.40 g kg⁻¹. Only a few sites in the southern region showed pH values of 5.50 or lower; others exceeded that level. According to the FAO land suitability classification, 29.87 % was rated as unsuitable, 69.08 % as moderately suitable, and just 1.06 % as suitable for maize cultivation. We recommend developing and enforcing policies to oversee infrastructure development and protect agricultural land. It is crucial to discourage non-regenerative farming practices, and both the government and private sectors should support farmers by providing access to modern soil resources.

与世界其他地区相比，尼日利亚西南部每公顷玉米产量是最低的。以土壤肥力决定因素和地理数据为重点的数字方法被用于评估土地适宜性。我们探索了一种将有序逻辑回归与连续土壤特征建模相结合的两步制图方法来评估土地适宜性。对环境变量进行逐步前向回归分析，以确定在95%置信水平上显著影响结果的环境变量（p < 0.05）。该地区大部分地区，从北到南，有机碳浓度低于1%。在北部，显著部分的总氮水平低于0.1 g kg−1。大部分地区的可交换磷含量在23至28 mg kg - 1之间，而东部一些地区的可提取钾含量在0.40 g kg - 1以上。只有南部少数样地的pH值在5.50以下；其他国家则超过了这一水平。根据粮农组织的土地适宜性分类，29.87%的土地不宜种植，69.08%的土地适宜种植，仅1.06%的土地适宜种植玉米。我们建议制定和执行监督基础设施发展和保护农业用地的政策。至关重要的是要阻止非再生农业的做法，政府和私营部门都应该通过提供获得现代土壤资源的途径来支持农民。

Biochar is increasingly regarded as a multifunctional amendment with the potential to enhance soil fertility, improve crop productivity, and contribute to climate change mitigation. This review examines 168 peer-reviewed studies published between 2005 and 2025 to assess the effects of biochar on soil physicochemical properties, microbial processes, nutrient dynamics, and environmental remediation. The findings indicate that biochar performance is highly dependent on feedstock type, pyrolysis conditions, soil characteristics, and climatic factors. Biochar improves soil structure, pH buffering capacity, cation exchange capacity, microbial resilience, yield improvement and greenhouse gas mitigation, but also presents risks such as nutrient immobilization and contaminant accumulation. Long-term application may alter soil biogeochemistry and microbial community structure. The review also evaluates barriers to field-scale adoption, including production cost, lack of technical knowledge, and limited policy support. Furthermore, it outlines future directions involving quality control, integration into circular bioeconomy systems, and carbon credit frameworks. This study provides a comprehensive assessment of biochar’s potential and limitations within sustainable soil management strategies under varying environmental and socioeconomic conditions.

生物炭越来越被视为一种多功能改良剂，具有增强土壤肥力、提高作物生产力和促进减缓气候变化的潜力。本综述回顾了2005年至2025年间发表的168项同行评议研究，以评估生物炭对土壤理化性质、微生物过程、养分动态和环境修复的影响。研究结果表明，生物炭的性能高度依赖于原料类型、热解条件、土壤特征和气候因素。生物炭改善了土壤结构、pH缓冲能力、阳离子交换能力、微生物恢复力、产量提高和温室气体减排，但也存在养分固定和污染物积累等风险。长期施用会改变土壤生物地球化学和微生物群落结构。该报告还评估了现场大规模采用的障碍，包括生产成本、缺乏技术知识和有限的政策支持。此外，它还概述了未来的发展方向，包括质量控制、融入循环生物经济系统和碳信用框架。本研究全面评估了在不同环境和社会经济条件下，生物炭在可持续土壤管理策略中的潜力和局限性。

Soil water conservation is a crucial aspect of dryland crop cultivation for mitigating the excessive heat and water stress induced by climate change. The application of acrylamide-based hydrogels is an effective soil management practice for enhancing water retention, controlling soil erosion, and improving soil health in water-limited regions. Hydrogels promote water conservation in soils, which increases water availability to plants and reduces the total irrigation demands. However, the systemic knowledge gaps of the effectiveness and application method of hydrogel materials and their quantified effects on degradability, drought resistance, irrigation system, and soil water conservation in arid and semi-arid environments have not been investigated extensively. Therefore, this review examines the impacts of hydrogels on soil water conservation, with a focus on their mechanisms, applications, and potential benefits in arid and semi-arid regions. The effects of hydrogels are compared with those of other soil water conservation techniques, such as mulching, biochar and compost, and their respective strengths and applicability in dryland regions are highlighted. The result of study indicates that hydrogels enhance water infiltration in soil, reduce surface runoff, and increase soil physio-chemical properties by improving the soil structure and aggregate stability. Hydrogels also reduce evaporation losses by 20–30 % by maintaining high soil moisture contents, which are crucial for healthy crop growth in water-limited areas. Furthermore, hydrogels minimize soil erosion, particularly in furrow and sprinkler irrigation systems. Despite their several benefits, the use of hydrogels in dryland agriculture poses challenges, such as environmental persistence, toxicity of acrylamide residues, and cost-effectiveness for small-scale farmers. Future research should address the potential environmental concerns associated with hydrogel use, including considerations of risk of degradation and toxicity to plant in different regions. Finally, the use of hydrogels based on a promising method for improving soil water retention in dryland agriculture is recommended.

水土保持是缓解气候变化引起的旱地作物过度高温缺水的一个重要方面。丙烯酰胺基水凝胶的应用是在缺水地区加强水土保持、控制水土流失、改善土壤健康的有效土壤管理措施。水凝胶促进土壤中的水分保持，这增加了植物的水分利用率，减少了灌溉的总需求。然而，关于水凝胶材料的有效性和应用方法及其在干旱和半干旱环境下对可降解性、抗旱性、灌溉系统和水土保持的量化影响的系统知识空白尚未得到广泛的研究。因此，本文综述了水凝胶对土壤水分保持的影响，重点介绍了水凝胶在干旱和半干旱地区的作用机制、应用和潜在效益。将水凝胶与覆盖、生物炭和堆肥等其他水土保持技术的效果进行了比较，强调了它们在干旱地区的优势和适用性。研究结果表明，水凝胶通过改善土壤结构和团聚体稳定性，增加土壤水分入渗，减少地表径流，提高土壤理化性质。水凝胶还通过保持较高的土壤水分含量来减少20 - 30%的蒸发损失，这对缺水地区作物的健康生长至关重要。此外，水凝胶可以减少土壤侵蚀，特别是在犁沟和喷灌系统中。尽管水凝胶有一些好处，但在旱地农业中使用水凝胶也带来了挑战，例如环境持久性、丙烯酰胺残留物的毒性以及小农的成本效益。未来的研究应解决与水凝胶使用相关的潜在环境问题，包括考虑降解风险和对不同地区植物的毒性。最后，介绍了利用水凝胶改善旱地农业土壤保水的一种很有前途的方法。

The rapid advancement of precision agriculture technologies and Agri-tech startups is transforming the global agricultural landscape, enhancing productivity, sustainability, and climate resilience. This study systematically reviewed 131 articles published between 2000 and 2024, selected using the PRISMA flow diagram from Scopus, ScienceDirect, Web of Science, Google Scholar, and grey literature sources. This study explores the role of precision agriculture technologies, including the Internet of Things (IoT), drones, and artificial intelligence (AI), in its adoption and effective use by farmers, for optimizing resource use, improving farm efficiency, and reducing environmental impacts in large size Australian farms. Despite their potential, widespread adoption faces challenges such as high implementation costs, technical constraints, and regulatory barriers. Additionally, Agri-tech startups play a crucial role in addressing climate change challenges by developing innovative solutions such as drought-resistant crops and climate-resilient farming methods. These advancements, when integrated with principles of agronomy and supported by strategic technology adoption, enhance the efficient use of resources. While the adoption of such technologies often involves an initial investment, their effective implementation can lead to more sustainable and resilient farming systems, ultimately promoting long-term productivity and environmental stewardship. However, inclusivity remains a critical issue, particularly in ensuring equitable access for small-scale farmers, women, and underrepresented groups in Agri-tech entrepreneurship. This study highlights the importance of supportive policies, financial investments, and training programs to facilitate broader adoption of emerging agricultural technologies. Based on the literature review and keyword co-occurrence analysis, this study developed nine hypotheses and subsequently proposed a conceptual model to examine the relationships among key variables in sustainable agriculture. Future research should focus on integrated approaches that assess agronomic, economic, and social aspects of precision agriculture and Agri-tech startups, fostering sustainable and inclusive agricultural development.

精准农业技术和农业科技初创公司的快速发展正在改变全球农业格局，提高生产力、可持续性和气候适应能力。本研究系统回顾了2000年至2024年间发表的131篇论文，采用PRISMA流程图从Scopus、ScienceDirect、Web of Science、b谷歌Scholar和灰色文献来源中选择。本研究探讨了精准农业技术，包括物联网（IoT）、无人机和人工智能（AI），在农民采用和有效使用精准农业技术方面的作用，以优化资源利用、提高农场效率，并减少澳大利亚大型农场对环境的影响。尽管它们具有潜力，但广泛采用面临着诸如高实施成本、技术限制和监管障碍等挑战。此外，农业科技初创公司通过开发抗旱作物和气候适应性耕作方法等创新解决方案，在应对气候变化挑战方面发挥着至关重要的作用。这些进步如果与农学原理相结合，并得到战略性技术采用的支持，就能提高资源的有效利用。虽然采用这类技术往往需要一项初始投资，但它们的有效实施可以带来更具可持续性和抗灾能力的农业系统，最终促进长期生产力和环境管理。然而，包容性仍然是一个关键问题，特别是在确保小农、妇女和代表性不足的群体公平参与农业技术创业方面。本研究强调了支持性政策、金融投资和培训计划对促进新兴农业技术更广泛采用的重要性。本研究在文献综述和关键词共现分析的基础上，提出了9个假设，并提出了可持续农业关键变量之间关系的概念模型。未来的研究应侧重于综合方法，评估精准农业和农业科技创业公司的农艺、经济和社会方面，促进可持续和包容性农业发展。

With the escalating impacts of climate change and growing climate variability, winter crop productivity in Australia faces substantial challenges, raising important concerns for food security and the sustainability of agricultural systems. This study addresses this challenge by analyzing how climatic and non-climatic factors have influenced winter crop yields in New South Wales from 1989 to 2023 using the Autoregressive Distributed Lag (ARDL) approach. Employing the Johansen and Juselius Cointegration (JJC) approach, we established the presence of long-run (persistent and structural changes over time) cointegration among the variables under investigation. Our findings reveal that rising levels of seasonal maximum temperature, rainfall, vapor pressure, and CO₂ concentrations bolster long-run crop productivity, while increasing minimum temperatures and solar radiation pose risks. However, non-climatic factors such as farm debt negatively affect crop productivity. Importantly, the varying short-run (immediate responses to changes in variables) effects underline the complexity of interactions between the crop yield and productivity drivers. These findings highlight the importance of implementing targeted agricultural practices that promote resilient and sustainable winter crop production in NSW in light of changing climate realities. Further research is also required to determine the influence of elevated CO₂ in winter crop plants at different growth stages, as CO₂ concentrations increase the winter crop production in this study.

随着气候变化的影响不断加剧和气候变异性的增加，澳大利亚的冬季作物生产力面临着重大挑战，引起了对粮食安全和农业系统可持续性的重要关注。本研究利用自回归分布滞后（ARDL）方法分析了1989年至2023年气候和非气候因素对新南威尔士州冬季作物产量的影响，从而解决了这一挑战。采用Johansen和Juselius协整（JJC）方法，我们在调查的变量之间建立了长期（随时间的持续和结构性变化）协整的存在。我们的研究结果表明，季节性最高温度、降雨量、蒸汽压和二氧化碳浓度的上升会提高作物的长期产量，而最低温度和太阳辐射的增加则会带来风险。然而，农业债务等非气候因素对作物生产力产生负面影响。重要的是，不同的短期效应（对变量变化的即时反应）强调了作物产量和生产力驱动因素之间相互作用的复杂性。这些发现强调了实施有针对性的农业实践的重要性，这些实践可以根据不断变化的气候现实促进新南威尔士州有弹性和可持续的冬季作物生产。由于本研究中CO2浓度增加了冬季作物产量，因此还需要进一步研究以确定不同生长阶段CO2升高对冬季作物植株的影响。

While several studies have examined soil fertility management systems under key food and cash crops in the Sub-Saharan Africa (SSA) region, there is a knowledge gap on soil fertility management under African Leafy Vegetables (ALV) small-holder farming practices particularly in Kenya. The objective of this study was to evaluate the influence of agronomic management and socio-economic factors on soil chemical fertility in the major ALV production zones in Kenya. Farm surveys were used to gather socio-economic data, while soil sampling was undertaken in all fields to collect soil chemical data. The findings indicated that Kisii County was characterized by higher proportions of wealthy and more educated farmers, with higher frequencies of input applications relative to Kakamega County. The soil pH was highest in Kenyenya, followed by Gucha, Butere, Mumias, and Khwisero. Gucha and Kenyenya had significantly the highest record of soil carbon concentrations of 3.2 and 3.1 %, respectively compared to other sites, such as Butere (2.0 %) and Khwisero (1.8 %), which had similar soil carbon concentrations, with Khwisero having the least (1.5 %) soil C. The highest mean Zn concentration was recorded in Gucha (6.5 mg kg⁻¹), followed by Kenyenya (6.4), Mumias (4.3), Butere (3.1) and Khwisero (3.0). The study showed that soil fertility under ALV farms in western Kenya was influenced by socio-economic factors and agronomic management factors. In general, the soil fertility status in Kisii County was better, compared to Kakamega County. Soil carbon was significantly influenced by site, soil texture, plot distance, fertilizer sources, and organic and inorganic fertilizer application frequencies. Gucha and Kenyenya Sub-Counties had higher SOC levels, averaging at 1.2 and 1.1 % higher, vis-a-vis Butere Sub-County, while Mumias and Khwisero Sub-Counties had lower average SOC levels in contrast to Butere Sub-County. Site differences can differentiate soil nutrient distribution due to inherent differences in soil characteristics and indirect effects arising from localized soil management practices.

虽然有几项研究审查了撒哈拉以南非洲（SSA）地区主要粮食和经济作物的土壤肥力管理系统，但在非洲叶菜（ALV）小农耕作方式下的土壤肥力管理方面存在知识缺口，特别是在肯尼亚。本研究的目的是评估肯尼亚主要ALV生产区的农艺管理和社会经济因素对土壤化学肥力的影响。利用农场调查收集社会经济数据，同时在所有领域进行土壤取样以收集土壤化学数据。研究结果表明，Kisii县的特点是富裕和受教育程度更高的农民比例更高，与Kakamega县相比，投入应用的频率更高。土壤pH值最高的是肯尼亚，其次是古查、Butere、Mumias和Khwisero。古查和肯尼亚的土壤碳浓度最高，分别为3.2和3.1%，而其他地点的土壤碳浓度相似，如Butere（2.0%）和Khwisero (1.8%)， Khwisero的土壤c最低（1.5%）。古查的平均锌浓度最高（6.5 mg kg - 1），其次是肯尼亚（6.4）、Mumias（4.3）、Butere（3.1）和Khwisero（3.0）。研究表明，肯尼亚西部ALV农场土壤肥力受社会经济因素和农艺管理因素的影响。总体而言，基思县的土壤肥力状况优于卡卡梅加县。土壤碳受立地、土壤质地、畦距、肥料来源、有机肥和无机肥施用频率的显著影响。古查县和肯尼亚县的有机碳含量较高，平均比Butere县高1.2%和1.1%，而Mumias县和Khwisero县的平均有机碳含量低于Butere县。由于土壤特性的内在差异和当地土壤管理实践的间接影响，场地差异可以区分土壤养分分布。
