The aim of the study was (1) the assessment of soil pollution with trace elements along a high-tra ffi c transport route, (2) determination of the content of trace elements in leaves of roadside trees, and (3) comparison of the usefulness of aqua regia with 1 mol dm –3 HCl and 0.01 mol dm –3 CaCl 2 for extraction of phytoavailable forms of Cd, Cu, Cr, Ni, Pb, and Zn from urban soil. The analysis covered contents of trace elements in soil and tree leaves along one of the main transport routes in Warsaw. The analysis of total contents of the studied metals (Cd, Cu, Cr, Ni, Pb, Zn) showed no exceedance of values acceptable for these elements in soil. The analysed tree species were characterised by variable ability to absorb trace elements. Usually White birch ( Betula pendula Roth) accumulated the highest amounts of the studied elements (especially Zn), and Swedish whitebeam ( Sorbus inter-media ) the lowest. The correlation between analysed trace elements concentration in tree leaves and soil suggests that the assessment of these metals pollution of soils is more e ffi cient by means of 1 mol dm –3 HCl than determination of total forms. It was also evidenced that trees can be used for the assessment of the state of pollution of the environment with trace elements.

Soil erosion is a severe risk on the sloping agricultural land due to improper managements. This study aimed to evaluate and compare the dynamics of soil loss and runoff under different land use types in order to fi nd the best soil erosion control for sustainable land use planning. A fi eld trial was conducted in Bor Krai village, Mea Hong Son Province, North-Western Thai Highlands during 2008–2009. Four land use types were selected for comparative measurement, including i) 4-year-fal-low land (FaL), ii) mixed orchard (MixO), iii) maize (M) and iv) upland rice (UR). Surface runoff (SR) and soil loss (SL) were monitored after each effective rainstorm using modi fi ed Gerlach troughs (GT). The GT was made of a bamboo and linked to a 50-litre container by a rubber hose. The size of GTs was 0.5–0.7 m long and 0.1–0.2 m diameter. The GTs were installed perpendicular to the contour line at the lower part of each land use. The results showed that, during the 2-yr, monoculture with inappropriate soil water conservation caused the fi rst average highest values of SR and SL (SR=299 m 3 ha –1 ) and (SL=3.4 t ha –1 ) while FaL yielded the lowest SR (41 m 3 ha –1 ) and SL (0.01 t ha –1 ) amounts. Moreover, further study is required for long-term prediction to estimate annual soil loss under different land use types.
由于管理不善，水土流失是坡耕地面临的严重风险。本研究旨在评价和比较不同土地利用类型下土壤流失和径流的动态变化，为可持续土地利用规划寻找最佳的土壤侵蚀控制方案。2008-2009年期间在泰国高地西北部Mea Hong Son省的Bor Krai村进行了实地试验。选择4种土地利用类型进行对比测量，分别为:1)4年荒地(FaL)、2)混合果园(MixO)、3)玉米(M)和4)旱稻(UR)。利用模拟Gerlach槽(GT)监测每次有效暴雨后的地表径流(SR)和土壤流失量(SL)。GT由竹子制成，通过一根橡胶管与一个50升的容器相连。GTs的尺寸为0.5-0.7 m长，0.1-0.2 m直径。在每个土地用途的下部垂直于等高线安装GTs。结果表明:2年期间，水土保持不合理的单作导致土壤的SR和SL平均最高(SR=299 m 3 ha -1)和(SL=3.4 tha -1)，而放养导致土壤的SR和SL最低(41 m 3 ha -1)和SL (0.01 tha -1)。此外，对不同土地利用类型下的年土壤流失量进行长期预测还需进一步研究。

In this study, we used HYDRUS-1D software to simulate soil water and nitrate (NO 3 -N) transport in a rainfed wheat fi eld under various nitrogen (N) fertilizer scenarios (0 to 126 kg ha –1 ) in Mo-rocco. We used inverse modeling to calibrate the input parameters involved in the simulation. The comparison between simulated and measured soil water (SWC) and NO 3 -N contents at different soil layers was carried out using the index of agreement ( d ), determination coe ffi cient ( R 2 ), RMSE , and MAE . By considering the soil pro fi le (0–100 cm), acceptable SWC simulation accuracies were obtained for the calibration and validation steps ( d =0.88–0.94, R 2 =0.67 to 0.80, RMSE =0.034–0.051 cm 3 cm –3 , and MAE =0.024–0.038 cm 3 cm –3 ), while NO 3 -N simulation was less accurate ( d =0.49–0.82, R 2 =0.20–0.58, RMSE =0.015–0.068 mg cm –3 , and MAE =0.012–0.046 mg cm –3 ). In addition, the observed NO 3 -N contents showed a lack of signi fi cant differences in the root zone (20–100 cm) between N fertilizer rates (p>0.05), which was consistent with the lack of N fertilizer effects on simulated NO 3 -N leaching below the soil pro fi le by HYDRUS-1D. The NO 3 -N leached amount accounted for 25 kg ha –1 and was derived mainly from the initial soil N contents. The simulated N balance of the soil pro fi le revealed that volatilization and denitri fi cation were the major pathways of N fertilizer loss, accounting for about 3.8 and 51.7% of the N fertilizer rates, respectively. We suggest further studies to improve the simulation accuracies of HYDRUS-1D using su ffi cient calibration data from long-term wheat experiments to ensure effective N fertilization management in the study area.
本研究采用HYDRUS-1D软件模拟Mo-rocco不同氮肥方案(0 ~ 126 kg ha -1)下旱作麦田土壤水分和硝态氮(NO 3 -N)的运移。我们使用逆建模来校准仿真中涉及的输入参数。采用一致性指数(d)、测定系数(r2)、RMSE和MAE对不同土层土壤水分(SWC)和NO 3 -N含量的模拟值与实测值进行比较。考虑土壤剖面(0 ~ 100 cm)，校准和验证步骤的SWC模拟精度可接受(d =0.88 ~ 0.94, r2 =0.67 ~ 0.80, RMSE =0.034 ~ 0.051 cm ~ 3 cm ~ 3, MAE =0.024 ~ 0.038 cm ~ 3 cm ~ 3)，而no3 -N模拟精度较低(d =0.49 ~ 0.82, r2 =0.20 ~ 0.58, RMSE =0.015 ~ 0.068 mg cm ~ 3, MAE =0.012 ~ 0.046 mg cm ~ 3)。此外，在根区(20 ~ 100 cm)不同施氮量间no3 -N含量无显著差异(p>0.05)，这与HYDRUS-1D模拟土壤剖面下no3 -N淋溶过程中无施氮效应一致。硝态氮的淋滤量为25 kg ha -1，主要来源于土壤初始氮含量。土壤氮素平衡模拟结果表明，挥发和反硝化是氮肥损失的主要途径，分别占氮肥损失率的3.8%和51.7%。建议进一步研究利用长期小麦试验数据，提高HYDRUS-1D的模拟精度，确保研究区氮肥的有效管理。

Long-term agricultural experiments allow for the determination of the in fl uence of agricultural practices on soil properties. The objective of the study was to determine the effect of 96-year-old fertilization (NPK mineral fertilization and farmyard manure (FYM) use) on selected physical and chemical soil properties. The research was carried out in an experimental fi eld in Skierniewice, central Poland, where the experiments have been conducted since 1923. Seven soil pro fi les (Reti-sols or Luvisols) were studied. Long-term fertilization caused various changes in the chemical properties of the studied soil (pH, the content of total organic carbon (TOC), total nitrogen (TN) and total sulphur (TS); exchangeable acidity (EA), total potential acidity (hydrolytic acidity) (TPA), cation exchange capacity (CEC), the total exchangeable bases (TEB), base saturation (BS)). The effect of long-term fertilization is most evident in the topsoil (the Ap horizon). The NPK fertilization led to acidi fi cation which was expressed by the decrease of soil pH (down to the value of 5.1), as well as the increase of EA, TPA, and exchangeable Al. Long-term high-dose FYM application (40 t and 60 t ha –1 per year) led to the stabilization of soil pH to a level of 6.2–6.5 throughout the soil pro fi le (down to 120 cm). The use of a combination of NPK fertilization and FYM application led to acidi fi - cation of the topsoil similar to the soil in which NPK fertilizers were applied alone. Long-term FYM application led to the increase in TOC, TN, and TS concentrations in the Ap horizons of the studied soils. Long-term use of NPK fertilizers had no signi fi cant effect on soil CEC, however long-term use of FYM increased the CEC in the Ap horizon of soils. An overall positive effect has been con fi rmed in the use of high doses of FYM (40 t and 60 t ha –1 per year), which improves the chemical properties (soil pH, TOC, TN, and TS content, as well as CEC) of the soil compared to the control plot and plots with NPK fertilization alone. These fi ndings were con fi rmed by PCCA analysis.
长期农业试验可以确定农业实践对土壤性质的影响。本研究的目的是确定96年施肥(氮磷钾矿肥和农家肥)对土壤理化性质的影响。这项研究是在波兰中部斯基尔尼维采的一个试验田进行的，自1923年以来一直在那里进行实验。研究了7种土壤亲性物质(红壤壤和露壤壤)。长期施肥对土壤化学性质(pH、总有机碳(TOC)、总氮(TN)和总硫(TS)含量)产生了不同程度的影响;交换酸度(EA)、总电位酸度(水解酸度)(TPA)、阳离子交换容量(CEC)、总交换碱(TEB)、碱饱和度(BS))。长期施肥的效果在表层土壤(Ap层)最为明显。施用氮磷钾导致土壤酸化，表现为土壤pH降低(降至5.1)，EA、TPA和交换性Al增加。长期高剂量施用(每年40 t和60 t ha -1)导致土壤pH在整个土壤剖面(低至120 cm)稳定在6.2-6.5的水平。氮磷钾和化肥混合施用导致表土酸化，与单独施用氮磷钾的土壤类似。长期施用FYM导致研究土壤Ap层TOC、TN和TS浓度升高。长期施用氮磷钾对土壤CEC影响不显著，而长期施用FYM可提高土壤Ap层的CEC。使用高剂量的FYM(每年40 t和60 t / h -1)总体上具有积极作用，与对照区和单独施用氮磷钾的区相比，它改善了土壤的化学性质(土壤pH、TOC、TN和TS含量以及CEC)。这些发现被PCCA分析证实。

Application of amino acids to soils is reportedly associated with controversial responses in soil enzyme activities. The effects of L-arginine application on the fl uorescein diacetate (FDA) hydrolysis and protease activity in an oak forest soil was investigated. The FDA hydrolysis and protease activity were regularly measured over a standard incubation period. The addition of L-arginine increased both FDA hydrolysis and protease activity after a lag time of 10 days. After 30 days, the ratio of FDA hydrolysis and protease activity in L-arginine-amended soil samples to those in the control reached 2.0 and 3.7, respectively. Moreover, FDA hydrolysis was found signi fi cantly (r = 0.67, P < 0.05) correlated with protease activity. It was concluded that L-arginine was able to stimulate FDA hydrolysis and protease activity, thereby making the soil hydrolytic system capable of facing more complicated substrates.

The study site La Chorquina ravine is located in the northern part of the Colombian in the western Andes region, where three alluvial fans with different altitudinal levels have been identi fi ed, being one of them the object of this study. These sedimentary deposits have been associated with the “El Guásimo” landslide, a downstream deposit that was considered responsible for the damming of the Cauca River. Paleoenvironmental reconstructions carried out during the last years question the existence of paleolakes, and support the hypothesis of a typical alluvial plain dynamic in fl u-enced by the Cauca River tributaries. In this research, two pro fi les were subjected to a complete pedostratigraphic fi eld characterization (structure, horizons differentiation, colour, porosity, and stoniness); Selected soil samples were submitted to physicochemical and mineralogical analyses, of which 11 micromorphological analysis were performed, and carbonates, gypsum, iron and manganese oxides, cutans, nodules, concretions and other pedological features were identi fi ed. The research proved the predominance of alluvial soils under an alluvial sedimentary environment with a predominance of features associated to the dynamic alluvial system characterized by little mineral alteration and similar mineralogical composition. The presence of carbonates and gypsum evidences seasonality changes in the climatic conditions. By means of the study of alluvial soils it is possible to identify paleoclimatic seasonality through edaphological records, which makes these soils a powerful tool for the study of Quaternary processes and paleoclimatic seasonality in tropical fl uvial environments.

By means of the study of alluvial soils it is possible to identify paleoclimatic seasonality through edaphological records, which makes these soils a powerful tool for the study of Quaternary processes and paleoclimatic seasonality in tropical fl uvial environments.","PeriodicalId":44772,"journal":{"name":"Soil Science Annual","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2022-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86392476","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ethnopedological studies focus on agricultural soils resulting in undervaluation of non-agricultural soil materials during land classi fi cation. In this study, ethnographic and ethnopedologic methods were used to obtain local knowledge and gain in-depth understanding of non-agricultural soils, their mineralogical and elemental composition relating to application in geophagy, healing and cosmetic purposes in two villages in KwaZulu-Natal, South Africa. In each village a questionnaire was administered to fi fty randomly selected individuals from which ten knowledgeable volunteers (in-cluding eight geophagists from two villages) provided details on the selection criteria, the desired properties and why the soils performed the claimed role. Users based their selection on macromor-phological features (e.g. colour, texture and location within the soil) and indigenous knowledge. Geophagic materials were mainly sourced from C horizons. They were mostly fi ne-grained with mica, kaolinite and quartz, and elements such as copper (Cu), zinc (Zn), cobalt (Co) and lead (Pb). Natural pigments, such as iron oxides in highly weathered soils, were recognised as sunscreen materials. Although the mechanisms were not understood by users, laboratory analyses showed that the mineralogical and chemical properties of the soil materials played a crucial role. The sunscreen and healing capabilities of these soils were related to high contents of titanium (TiO 2 ) and iron (Fe 2 O 3 ) and the presence of kaolinite. Further appraisal of these soil materials is necessary for their conservation and inclusion in land classi fi cation.
