Understanding the dynamics and transformation of soil phosphorus (P) is imperative for formulating sustainable agricultural P management strategies. This study examined the long-term impacts (over 52 cropping cycles) of various fertilization regimes on P dynamics in Inceptisol (Typic Ustochrept) and the associated productivity of the maize-wheat cropping system. The fertilizer treatments involved: T1) control, T2) 50 % NPK, T3) 100 % NPK (120:26.5:25.0 kg ha−1, N:P:K), T4) 100 % NPK, T5) 150 % NPK, and T6) 100 % NPK + farmyard manure (FYM @10,000 kg ha−1), implemented in a randomized block design with three replicates. The source of P was single super phosphate, except T4 (diammonium phosphate). The results highlight a significant accumulation of P under continuous fertilization compared to the control treatment. Olsen P in surface soil under the 100 % NPK + FYM treatment exhibited an increase of 522 % relative to the control and 108 % compared to the 100 % NPK treatment. The accumulation was characterized by varied distributions across inorganic and organic P fractions, which were influenced by the fertilizer applications. A general enhancement in P fractions was observed with fertilization, with levels ranging from a minimum under 50 % NPK to a maximum under 100 % NPK + FYM treatment. The distribution of P fractions followed the order: Ca-P > Al-P > Org-P > Fe-P > Red-P (reductant-soluble phosphate) > Sol-P (soluble P). Regarding the distribution of P fractionation, an incubation study was conducted to assess the effects of organic amendments, specifically paddy straw and FYM, on P fractions at different levels of added P. The findings revealed a pronounced enhancement in P distribution into its labile fractions. The P balance sheet indicated a net positive soil P balance following 52 cropping cycles under varied fertilization except control. Additionally, correlations between soil P fractions and crop yield were calculated. These findings necessitate further investigation to refine P management strategies to optimize the utilization of residual P for sustainable crop production.
了解土壤磷的动态和转化规律对制定可持续的农业磷管理策略至关重要。本研究考察了不同施肥制度(超过52个种植周期)对ineptisol磷动态的长期影响(典型ustochrep)以及玉米-小麦种植系统的相关生产力。施肥处理包括:T1)对照,T2) 50%氮磷钾,T3) 100%氮磷钾(120:26.5:25.0 kg ha - 1, N:P:K), T4) 100%氮磷钾,T5) 150%氮磷钾,T6) 100%氮磷钾+农家肥(FYM @10,000 kg ha - 1),采用随机区组设计,共3个重复。P的来源除T4(磷酸二铵)外均为单一超磷酸盐。结果表明,与对照处理相比,连续施肥显著增加了磷的积累。与对照相比,100% NPK + FYM处理的表层土壤奥尔森磷含量增加了522%,与100% NPK处理相比增加了108%。无机磷和有机磷的积累分布不同,受施肥影响较大。施磷量总体上提高,最低氮磷钾低于50%,最高氮磷钾+ FYM处理为100%。P组分的分布顺序为:Ca-P >; Al-P > Org-P > Fe-P > Red-P(还原性可溶性磷酸盐)> Sol-P(可溶性磷)。通过培养试验,研究了不同磷添加水平下有机改进剂(特别是稻秆和FYM)对磷组分的影响。结果表明,有机改进剂显著增强了磷在不稳定组分中的分布。除对照外,不同施肥条件下52个种植周期土壤磷平衡均为净正值。此外,还计算了土壤磷组分与作物产量的相关关系。这些发现需要进一步的研究来完善磷管理策略,以优化剩余磷的利用,实现作物的可持续生产。

Soil bulk density (BD) is a critical variable in the estimation of carbon (C) stocks, which are central to agriculture-based C projects. However, field sampling of BD is often labor-intensive and costly. Pedotransfer functions (PTFs), which estimate BD from easily measured soil attributes, provide a promising alternative. This study evaluated 6941 observations from plots under grain production (GR) and 1246 from native vegetation (NV), sampled down to 1 m depth across 47 farms in the South-Central region of Brazil. Each observation included BD and the contents of sand, silt, clay, and C. Thirty-three PTFs from the international literature were tested, and four new ones (F34, F35, F36, F37) were developed. Function performance was assessed using the correlation coefficient (r), function efficiency (FE), mean error (ME), and root mean square error (RMSE). Two literature-based PTFs and the four developed in this study achieved the best performance, with RMSE ranging from 0.11 to 0.20 and ME from −0.01 to 0.09. Among them, F36 and F37 showed the strongest predictive ability, with FE values of 0.41 and 0.66 and r of 0.74 and 0.81, respectively. Carbon stocks estimated from BD predicted by the selected PTFs were strongly correlated with measured stocks (r > 0.90), demonstrating that these functions are reliable alternatives to direct BD measurements for estimating C stocks. For conservative application in C projects, function F37 is recommended for layers below 30 cm, while BD should continue to be directly measured in shallower layers, where management practices exert stronger influence.
土壤容重(BD)是估算碳储量的关键变量,是农业碳项目的核心。然而,BD的现场采样往往是劳动密集型和昂贵的。土壤传递函数(ptf)是一种很有前途的替代方法,它可以从容易测量的土壤属性中估计出BD。本研究评估了来自粮食生产(GR)地块的6941个观测值和来自原生植被(NV)的1246个观测值,采样深度为1 m,分布在巴西中南部地区的47个农场。对国际文献中的33个PTFs进行了测试,并开发了4个新的PTFs (F34、F35、F36、F37)。使用相关系数(r)、功能效率(FE)、平均误差(ME)和均方根误差(RMSE)评估功能性能。2种基于文献的ptf和本研究开发的4种ptf表现最佳,RMSE范围为0.11 ~ 0.20,ME范围为- 0.01 ~ 0.09。其中F36和F37的预测能力最强,FE分别为0.41和0.66,r分别为0.74和0.81。所选ptf预测的从BD估计的碳储量与实测储量密切相关(r > 0.90),表明这些函数是直接测量BD估算碳储量的可靠替代方法。对于C项目保守应用,建议在30cm以下的层数使用F37函数,而在管理实践影响较大的较浅层数继续直接测量BD。

Agricultural activity in drained lowlands accelerates peat decomposition and greenhouse gas emissions. Rewetting is increasingly adopted across Europe to mitigate these emissions, but its effects on soil microbial communities remain poorly understood. We examined prokaryotic communities and network structure in Danish lowland soils designated for potential rewetting to improve our understanding of these communities and their drivers. We included less-studied soil properties linked to hydrology and structure (soil water content at field capacity, van Genuchten pore-size distribution index (n), and soil water repellency (SWR)) in addition to common properties such as pH and organic carbon (OC). We analysed 113 soil samples across land-use types (grass, fallow, crop, other) spanning mineral to organic soils with gradients in pH (2.0–7.6), OC (0.025–0.499 kg kg-1), SWR (33.9-71.3 mN m-1), and soil structure (n: 1.1-1.3). Prokaryotic alpha diversity (Shannon-Wiener index: 2.9–5.7) was best predicted by pH, followed by porosity and n. Together, pH, porosity, n, and OC accounted for 24.5% of the variance in community composition. Hierarchical clustering identified three prokaryotic clusters strongly aligned with pH. Network analysis revealed marginal differences when comparing samples from fallow and grass, while complexity increased progressively across clusters. Interestingly, high-pH soils showed the highest alpha diversity but the least complex networks, while low-pH soils showed the opposite. In conclusion, soil pH emerged as the dominant driver of prokaryotic communities in Danish lowlands, but hydrological and structural properties also played important roles. Network complexity provided complementary insights into ecosystem organisation beyond diversity alone.
排水低地的农业活动加速了泥炭的分解和温室气体的排放。欧洲各地越来越多地采用复湿法来减少这些排放,但其对土壤微生物群落的影响仍然知之甚少。我们研究了丹麦低地土壤中指定的潜在再润湿的原核群落和网络结构,以提高我们对这些群落及其驱动因素的理解。除了pH和有机碳(OC)等常见特性外,我们还纳入了与水文和结构相关的较少研究的土壤特性(田间容量下的土壤含水量、van Genuchten孔径分布指数(n)和土壤疏水性(SWR))。我们分析了113个不同土地利用类型(草地、休耕、作物等)的土壤样品,包括矿质到有机土壤的pH(2.0-7.6)、OC (0.025-0.499 kg kg-1)、SWR (33.9-71.3 mN m-1)和土壤结构(n: 1.1-1.3)的梯度。pH对原核α多样性(Shannon-Wiener指数:2.9 ~ 5.7)的预测效果最好,其次是孔隙度和n。pH、孔隙度、n和OC共占群落组成方差的24.5%。分层聚类鉴定出3个与ph值高度一致的原核生物聚类。网络分析显示,休耕和草地样品之间存在边际差异,而聚类之间的复杂性逐渐增加。高ph土壤的α多样性最高,但其复杂网络最少,而低ph土壤则相反。结果表明,土壤pH值是丹麦低地原核生物群落的主要驱动因素,但水文和结构特性也起着重要作用。网络复杂性提供了对生态系统组织的补充见解,而不仅仅是多样性。

In Quebec, Canada, field vegetable production largely occurs on cultivated organic soils of Montérégie. These soils become arable following extensive drainage of peatlands, which are highly fertile but vulnerable to subsidence, erosion, and organic matter mineralization. The latter causes carbon losses to the atmosphere through CO₂ emissions and can also lead to dissolved organic carbon leaching. This study quantified CO₂ emissions and identified governing edaphic and meteorological parameters to support the development of carbon compensation strategies for peatland managers. Easily measurable soil parameters were selected to provide farmers with potential proxies for routine soil analysis.
Five commercial sites were selected based on their organic matter (OM) content: F1 (52.2 %), F2 (56.7 %), F3 (74.0 %), F4 (77.4 %), and F5 (91.3 %). All sites, except F3, were devoid of vegetation. Soil CO₂ emissions were measured using manual static chambers over one year (September 2021–September 2022) at bimonthly intervals. Gross annual carbon losses were 4.94 Mg C-CO₂ ha−1 yr−1 for F1, 5.47 for F2, 15.30 for F3, 7.62 for F4, and 3.20 for F5.
Soil temperature, total microbiological activity (fluorescein diacetate hydrolysis), total nitrogen, and pH significantly and positively influenced CO₂ fluxes, while soil water content showed a negative correlation. Annual carbon losses were highly and exponentially correlated with total microbiological activity, underscoring its relevance as a biological indicator and promising proxy for CO₂ emissions.
This study advances understanding of CO₂ emissions from cultivated organic soils and highlights the importance of targeted strategies to mitigate carbon losses and conserve these valuable peatland resources.
在加拿大魁北克省,大田蔬菜生产主要发生在蒙塔姆萨的有机土壤上。这些土壤在泥炭地大量排水后成为可耕地,泥炭地非常肥沃,但容易下沉、侵蚀和有机质矿化。后者通过二氧化碳排放导致碳损失到大气中,也可能导致溶解的有机碳浸出。本研究量化了二氧化碳排放量,并确定了控制的地理和气象参数,以支持泥炭地管理者制定碳补偿战略。选择容易测量的土壤参数,为农民提供常规土壤分析的潜在代理。根据有机质(OM)含量选择5个商业用地:F1(52.2%)、F2(56.7%)、F3(74.0%)、F4(77.4%)和F5(91.3%)。除F3外,所有地点都没有植被。土壤CO₂排放量采用手动静态室,每隔两个月测量一年(2021年9月- 2022年9月)。F1的年碳损失总量为4.94 Mg C-CO₂ha - 1年,F2为5.47 Mg, F3为15.30 Mg, F4为7.62 Mg, F5为3.20 Mg。土壤温度、总微生物活性(双醋酸荧光素水解)、总氮和pH显著正影响co2通量,土壤含水量呈负相关。年碳损失与总微生物活性呈高度指数相关,强调了其作为CO₂排放的生物学指标和有希望的代理的相关性。这项研究促进了对栽培有机土壤CO 2排放的理解,并强调了有针对性的策略来减轻碳损失和保护这些宝贵的泥炭地资源的重要性。

Enhancing forage and beef productivity in natural grasslands is essential to prevent their conversion into annual crops, planted pastures, and forests. This strategy is pivotal for preserving ecological balance and promoting biodiversity conservation. The present meta-analysis assesses the effects of various improvement technologies on forage and animal production in southern Brazil's natural grasslands. These technologies include liming, fertilization with N, P, K, and S, and the overseeding of exogenous forage species, with a focus on enhancing soil chemical parameters and forage production. A total of 506 sample pairs were compiled from 49 studies conducted between 1967 and 2020. The natural grassland without fertilization and/or overseeding served as the control. Each pair of observations compared the control to treatments involving liming, fertilization, and/or overseeding. The applied improvement technologies yielded an average increase of 44 % in forage production and 82 % in animal production per hectare, respectively. In studies that focused exclusively on forage productivity, the average increase was 34 % compared to the control. Natural grasslands on soils with lower innate fertility, such as Arenosol, Acrisol, Planosol, or Plinthosol, exhibited a more substantial response (+98 %) when doses of N + P + K + S exceeded 234 kg ha−1. In contrast, soils with higher natural fertility, including Leptosol/Regosol, Nitisol, Ferrasol, Luvisol, and Vertisol, showed increases ranging from +6 to +36 % compared to the control. These findings indicate that focusing improvement technologies on natural grasslands developed on soils with significant chemical constraints is beneficial.

提高天然草原的饲料和牛肉产量对于防止它们变成一年生作物、人工牧场和森林至关重要。这一战略对维护生态平衡和促进生物多样性保护具有重要意义。本荟萃分析评估了各种改良技术对巴西南部天然草原饲料和动物生产的影响。这些技术包括石灰化、N、P、K、S施肥和外源牧草种的过量播种,重点是提高土壤化学参数和饲料产量。1967年至2020年间进行的49项研究共收集了506对样本。对照为不施肥和(或)不播种的天然草地。每对观察都将对照与施石灰、施肥和/或过度播种的处理进行了比较。应用改良技术后,每公顷牧草产量平均提高44%,牲畜产量平均提高82%。在专门研究牧草产量的研究中,与对照相比,平均增加了34%。天然草地在天然肥力较低的土壤上,如砂硝土、阿克里索土、Planosol或Plinthosol,当N + P + K + S剂量超过234 kg ha - 1时,表现出更显著的响应(+ 98%)。相比之下,自然肥力较高的土壤,包括瘦土/雷果土、硝土、费拉索、露维索和维维索,与对照相比,增幅在+ 6%至+ 36%之间。这些发现表明,在具有明显化学约束的土壤上开发的天然草地,重点改进技术是有益的。此外,为了维持天然草地,建议在调整土壤肥力的同时结合冷季物种管理,以最大限度地提高饲料和动物的生产力。

Estimation of ammonia (NH3) emissions requires calculation of emission factors (EFs) based on experimental data that reflects seasonal and climatic variability, particularly in an annual triple cropping system. However, data on season-specific EFs under varying climate regimes are required to develop the management strategies that help mitigate nitrogen (N) loss via volatilization. A large portion of N releases into atmosphere from rice soils causing both economic and environmental costs since farmers indiscriminately use N fertilizers for rice production. Ammonia emissions and EFs were assessed in two different rice growing sites with an annual Boro–Aus–Aman sequence. Two sets of treatments were used: two residue treatments (no residue incorporation, NR; and 30 %, by height, crop residue incorporation, CR); and four N levels (control, CL; farmers' practice, FP; recommended nitrogen dose, RD; and 125 % of RD, 125RD). Crop residue incorporation significantly elevated NH3 emissions. CR coupled with 125RD exhibited 10–27 %, 6–7 % and 6–9 % higher NH3 emissions than NR-125RD in Boro, Aus and Aman seasons, respectively. Although the recommended N rate was higher in Boro, NH3 emission was higher in Aman rice (28–34 kg NH3-N ha−1) suggesting that climatic conditions are the most influential driver rather than the N rate. Likewise, NH3 EFs in RD ranged from 11 to 18 %, 16–33 % and 28–34 % in Boro, Aus and Aman seasons, respectively. Our results indicate that NH3 emissions do not only depend on N rate but also on seasons where consideration of seasonal EFs is required to improve NH3 and N budget. By contrast, N rate and crop residue did not influence N leaching but leaching was a considerable part of N loss from rice fields. Overall, our findings underscore the critical need for season-specific N fertilizer management including crop residue incorporation in multi-cropped rice systems to effectively mitigate NH3 emissions while maintaining productivity.
估算氨(NH3)排放需要根据反映季节和气候变化的实验数据计算排放因子(EFs),特别是在一年生三熟制中。然而,需要不同气候条件下的季节性生态系统数据来制定有助于减少氮挥发损失的管理策略。由于农民在水稻生产中不加选择地使用氮肥,很大一部分氮从水稻土壤中释放到大气中,造成了经济和环境成本。利用年度Boro-Aus-Aman序列对两个不同水稻产地的氨排放和EFs进行了评估。试验采用两组处理:两组残茬处理(不掺入残茬,NR;按高度30%,掺入作物残茬,CR);4个氮素水平(对照,CL;农民实践,FP;推荐施氮量,RD和125%的RD, 125RD)。作物残茬掺入显著增加了NH3排放量。在Boro、Aus和Aman季节,CR -125RD的NH3排放量分别比NR-125RD高10 - 27%、6 - 7%和6 - 9%。虽然建议施氮量在波罗稻较高,但氨氮排放量在阿曼稻较高(28-34 kg NH3-N ha - 1),表明气候条件是最重要的驱动因素,而不是施氮量。与此相似,北坡、澳洲和安曼季节的NH3 EFs分别为11% ~ 18%、16 ~ 33%和28 ~ 34%。研究结果表明,NH3排放不仅与N速率有关,而且与季节有关,因此需要考虑季节性EFs来改善NH3和N的收支。施氮量和作物残茬对氮素淋失没有影响,但淋失是稻田氮素损失的重要组成部分。总的来说,我们的研究结果强调了在多茬水稻系统中进行季节性氮肥管理的迫切需要,包括作物残茬的掺入,以有效减少NH3排放,同时保持生产力。

Brazil is largely occupied by pastures under varying conditions, rising needs for systematic assessment of soil fertility and improvement of management strategies. Soil analyses are valuable tools for fertility assessment, but its use can be amplified to foster information exchanges between farmers, service providers and fertilizer vendors in broader scales. So, our objective was to characterize the fertility dynamic of Brazilian pastures through its soil chemical and physical properties. We employed soil analysis results collected from different land uses (pasture, integrated system, and native vegetation), soil depths (0–5 cm, 5–10 cm, 10–20 cm, and 20–30 cm) and textural classes extracted from the Brazilian Soil Classification System to determine Land Use Fertility Profiles based on two core dimensions representing soil fertility and acidity, addressing 35 % and 24 % of the total variance, respectively. Stratified comparisons showed that the acidity dimension distinguished native vegetation from integrated system soils; fertility differences between textural groups in superficial layers were more frequent among pastures samples than among integrated systems ones and diminished in depth. The acidity dimension remained differing sandy and medium texture soils from clayey and heavy clayey ones. In the crossed comparisons, our results indicated that sandy soils under pasture concentrate their heterogeneity in deeper layers (20–30 cm). Thus, sampling schemes should be conducted up to these depths to improve efficiency in management strategies. This approach aimed at contributing to the data-modeling scope of agribusiness digital transformation and to the global agenda for sustainable food supply by enhancing soil fertility efficiency.
巴西主要是各种条件下的牧场,对土壤肥力的系统评估和改进管理战略的需求日益增加。土壤分析是评估肥力的宝贵工具,但它的用途可以扩大,以促进农民、服务提供者和肥料供应商之间更广泛的信息交流。因此,我们的目标是通过土壤化学和物理特性来描述巴西牧场的肥力动态。我们利用从不同土地利用(牧场、综合系统和原生植被)、土壤深度(0-5厘米、5-10厘米、10-20厘米和20-30厘米)和巴西土壤分类系统中提取的质地分类收集的土壤分析结果,基于代表土壤肥力和酸度的两个核心维度确定土地利用肥力剖面,分别解决了总方差的35%和24%。分层比较表明,酸度维度区分了原生植被与综合系统土壤;表层质地组之间的肥力差异在牧场样品中比在综合系统样品中更频繁,并且在深度上减小。砂质土和中等质地土与粘性土和重粘性土的酸度维度存在差异。交叉比较结果表明,放牧条件下沙质土壤的异质性主要集中在20 ~ 30 cm土层。因此,应该在这些深度进行抽样方案,以提高管理战略的效率。该方法旨在通过提高土壤肥力效率,为农业综合企业数字化转型的数据建模范围和可持续粮食供应的全球议程做出贡献。

This study was conducted to determine the impact of land use and livestock farming on riparian areas in the state of São Paulo, Brazil. A range of physical, hydraulic and chemical properties were measured in hydromorphic soils under four scenarios; namely: i) native vegetation (NV), ii) semi-extensive grazing (SEG, ∼21 animal units ha−1) with 30 years of established practice; iii) intensive grazing with 20 years of established practice (IG20, ∼24 animal units ha−1); and iv) intensive grazing after 1 year of being implemented (IG1, ∼21 animal units ha−1). The replacement of native vegetation with pastures, regardless of the duration and type of management, resulted in significant changes in soil structure and soil functioning, due to increased bulk density and penetration resistance, and concurrent reductions in macroporosity and saturated hydraulic conductivity. The soil under long-term intensive management (IG20) showed less structural degradation, closely resembling the conditions observed in the native vegetation area (NV). By contrast, the soil under semi-extensive grazing (SEG) management exhibited significant damage to the soil structure, which affected all measured soil physical and hydraulic properties. Despite these negative impacts on soil structure, SEG exhibited higher levels of total carbon, total nitrogen, and total sulfur. The results suggested that the intensive management system (IG20) tended to maintain higher soil quality in riparian areas than the condition observed under native vegetation, although these differences cannot be exclusively ascribed to grazing.
本研究旨在确定巴西圣保罗州土地利用和畜牧业对河岸地区的影响。在四种情况下,测量了水形态土壤的一系列物理、水力和化学性质;即:i)原生植被(NV), ii)半粗放放牧(SEG,约21动物单位/公顷),已有30年的实践经验;iii)集约放牧,已有20年的实践(IG20, ~ 24动物单位/公顷);iv)实施1年后的集约放牧(IG1, ~ 21动物单位ha - 1)。用牧场取代原生植被,无论持续时间和管理类型如何,都会导致土壤结构和土壤功能发生显著变化,因为土壤容重和渗透阻力增加,同时宏观孔隙率和饱和水力导电性降低。长期集约管理(IG20)下的土壤结构退化程度较低,与原生植被区(NV)相似。半粗放放牧(SEG)对土壤结构的破坏显著,影响了土壤的物理和水力特性。尽管对土壤结构有负面影响,但SEG表现出较高的总碳、总氮和总硫水平。结果表明,集约管理系统(IG20)在河滨地区的土壤质量比在原生植被下观察到的条件更高,尽管这些差异不能完全归因于放牧。

The Brazilian Latossolos (Ferralsols-WRB, Oxisols-Soil Taxonomy) are generally well-drained soils, strongly and deeply altered, rich in Al and Fe oxyhydroxides, nutrient-poor and morphologically uniform, due to long-term weathering and continuous leaching. Despite the occurrence in all Brazilian territory, little is known about the variability of basic attributes of Latossolos across the country. We hypothesize that the Brazilian Latossolos present a considerable variability in soil attributes that can be regionally manifested and traced according to the environmental characteristics of different Brazilian biomes. In this way, we compared a suite of soil attributes from Latossolos Amarelos, Latossolos Vermelho-Amarelos and Latossolos Vermelhos from the biomes Amazonia, Atlantic Forest, Cerrado, and Caatinga biomes, using robust legacy data produced by published soil surveys. The Latossolos Vermelhos represent the suborder with the greatest degree of weathering, exhibiting the highest contents of Fe and Al oxyhydroxides, clayey texture, greatest microaggregate development, pH and base saturation, and presenting the lowest contents of available P. Conversely, the Latossolos Amarelos exhibited the highest contents of kaolinite, silt, sand, and the highest soil consistency and Al saturation. The Latossolos Vermelho-Amarelos, in turn, presented intermediate characteristics, confirming that soil color is a key attribute for differentiating the pedogenetic development of Latossolos, regardless of the biome. With reference to the Brazilian biomes, the Latossolos of the Cerrado and Atlantic Forest presented the greatest weathering degree, evidenced by the lowest values of Ki, Kr, and silt/clay ratios, as well as other characteristics that reveal the great intensity of desilication, ferralitization, gibbsitization and pedalization. Despite the hot and wet equatorial climate and the general soil acidity in Amazonia, Amazonian Latossolos presented lower pedogenetic development than the Cerrado and Atlantic Forest soils, which are in close association with the sedimentary parent material, resilication by forest Si cycling, subdued topography and poor soil internal drainage. The Latossolos from the semi-arid Caatinga showed the lowest weathering and pedogenesis degrees, and represent relict soils from past wetter climates, preserved in the only Brazilian semi-arid biome.
巴西Latossolos (Ferralsols-WRB, Oxisols-Soil Taxonomy)是一种排水良好、蚀变强烈、蚀变深度深、富含Al和Fe氢氧化物、营养不良、形态均匀的土壤,主要受长期风化和连续淋滤作用的影响。尽管在巴西全境都有发生,但人们对拉托索罗基本属性在全国范围内的可变性知之甚少。我们假设巴西Latossolos在土壤属性方面存在相当大的变异性,可以根据巴西不同生物群系的环境特征进行区域表现和追踪。通过这种方式,我们比较了来自亚马逊、大西洋森林、塞拉多和Caatinga生物群系的Latossolos Amarelos、Latossolos Vermelho-Amarelos和Latossolos Vermelhos的一套土壤属性,使用了由已发表的土壤调查产生的可靠遗留数据。Vermelhos是风化程度最大的亚目,表现出最高的铁和铝氢氧化物含量、粘土质地、最大的微团聚体发育、pH和碱饱和度,表现出最低的有效磷含量。相反,Latossolos Amarelos表现出最高的高岭石、粉砂、砂含量,以及最高的土壤稠度和铝饱和度。而Vermelho-Amarelos则表现出中间特征,证实了土壤颜色是区分不同生物群系的Latossolos成土发育的关键属性。与巴西生物群系相比,塞拉多和大西洋森林的拉托索洛风化程度最大,Ki、Kr、粉土比最低,脱硅、铁氧体化、三水石化、壤化等特征强烈。尽管亚马孙地区赤道气候湿热,土壤酸度普遍较高,但亚马孙Latossolos土壤的成土发育程度低于Cerrado和大西洋森林土壤,这与沉积母质、森林硅循环的恢复作用、地形的抑制和土壤内部排水能力差密切相关。来自半干旱Caatinga的Latossolos表现出最低的风化和成土程度,代表了过去湿润气候的残余土壤,保存在巴西唯一的半干旱生物群系中。

The Latossolos from the semi-arid Caatinga showed the lowest weathering and pedogenesis degrees, and represent relict soils from past wetter climates, preserved in the only Brazilian semi-arid biome.</div></div>","PeriodicalId":56001,"journal":{"name":"Geoderma Regional","volume":"43 ","pages":"Article e01012"},"PeriodicalIF":3.3,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145222368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The delivery of soil-based ecosystem services (ES) is of increasing importance for spatial planners. Soils are complex and heterogeneous systems, therefore synthesizing pedological expertise into decision support maps presents ongoing challenges. Our approach considers the properties of the entire pedon to assess the contribution of different soil types and land covers to ES delivery at the territorial scale.
This study adapts the Destisol decision support tool, initially developed for urban soils and therefore adapted to a high variety of pedons influenced by human activities, to a rural setting containing croplands, grasslands and forests. 86 soil profiles from the study territory are grouped into eight dominant soil types. Nine ES are evaluated based on the horizon-specific physico-chemical properties of each soil type, and mapped following a territorial 1/50,000 pedological map.
The study territory has a high potential for ES provision with a mean score of 2 +/− 0.2 (min: 1.7, max: 2.7) on a scale of 0 to 3. Soil type is shown to have a significant impact on ES supply under the same land cover. Eutric Cambisols rank highly for provisioning and regulating services, Gleysols rank poorly for water quality but highly for global climate mitigation, and shallow rocky soils rank poorly for most services except water infiltration. Mapping results and soil-type specific ES scores can be used as spatial planning tools to quantify the impact of a given scenario of land cover change on ES scores, and thereby contribute to efforts towards no net loss of soil functionality.
土壤生态系统服务(ES)的提供对空间规划者来说越来越重要。土壤是复杂的异质系统,因此将土壤学专业知识综合到决策支持地图中提出了持续的挑战。我们的方法考虑了整个土地的性质,以评估不同土壤类型和土地覆盖对领土尺度上ES传递的贡献。本研究将Destisol决策支持工具(最初是为城市土壤开发的,因此适用于受人类活动影响的多种土壤)调整为包含农田、草原和森林的农村环境。研究区86条土壤剖面被划分为8种主要土壤类型。根据每种土壤类型的水平特异性物理化学性质对9个ES进行了评估,并按照1/50,000的领土土壤学地图进行了绘制。在0到3分的范围内,研究区域提供ES的潜力很大,平均得分为2 +/ - 0.2(最低得分为1.7,最高得分为2.7)。在相同土地覆盖下,土壤类型对ES供应有显著影响。营养盐Cambisols在提供和调节服务方面排名靠前,Gleysols在水质方面排名靠后,但在全球气候减缓方面排名靠前,浅岩质土壤在除水渗透外的大多数服务方面排名靠后。制图结果和特定土壤类型的ES得分可作为空间规划工具,量化给定土地覆盖变化情景对ES得分的影响,从而有助于实现土壤功能无净损失的目标。
