This study has been done to see the impact of phosphorus (P) on the concentration of cadmium (Cd) chemical fractions in two sorts of calcareous soils within the Fars province in Iran. Because of these interactions, we looked at the in fl uence of phosphorus on cadmium fractions. Variables were three levels of Cd (0.0, 30.0 and 60.0 mg kg -1 of soil from CdSO 4. 8H 2 O), three levels of p (0.0, 50.0 and 100.0 mg kg -1 of soil from Ca (H 2 PO 4 ) 2. H 2 O, three levels Incubation time (2, 4 and 8 weeks) and two sorts of soil (clay and sandy clay loam). The randomized completed block design (RCBD) was used for this research. After 2, 4 and 8 weeks of treatments, the sequential extraction procedure was done to determine cadmium concentration in WsEx (Water Soluble and Exchangeable), Sorb (EDTA ex-tractable), MnOx (Manganese Oxides), Car (Carbonate), OM (Organic matter), AFeOx (Amorphous Iron Oxides), CFeOx (Crystaline Fe oxides) and Res (Residual) fractions. The results showed that 69.0 to 71.0% of the added Cd was removed within the WsEx, Sorb and MnOx fractions. Cadmium concentration in Sorb, OM and Res fraction was higher within clay soil while cadmium concentration within WsEx and Car fractions were higher within sandy clay loam soil. Adding P as monocalcium phosphate reduced cadmium concentration within WsEx and Sorb fractions while increased Car, OM and Res fractions. The presence of phosphorus reduces the concentration of Cd in those forms that are easily released into soil solution (WsEx and Sorb) from where they’ll be absorbed by plants and thus decrease cadmium uptake by plants.
在伊朗法尔斯省的两种钙质土壤中，研究了磷(P)对镉(Cd)化学组分浓度的影响。由于这些相互作用，我们研究了磷对镉组分的影响。变量为3个水平的Cd(0.0、30.0和60.0 mg kg -1)。8H 2o)，三个水平的p(0.0、50.0和100.0 mg kg -1)来自Ca (h2po4) 2的土壤。h2o，三个层次的培养时间(2,4和8周)和两种土壤(粘土和砂质粘土壤土)。本研究采用随机完全区设计(RCBD)。经过2周、4周和8周的处理，进行顺序提取程序，以测定WsEx(水溶性和可交换性)、Sorb (EDTA萃取)、MnOx(锰氧化物)、Car(碳酸盐)、OM(有机物)、AFeOx(无定形铁氧化物)、CFeOx(结晶铁氧化物)和Res(残余)馏分中的镉浓度。结果表明，在WsEx、Sorb和MnOx馏分中，添加Cd的去除率为69.0% ~ 71.0%。粘土土壤中Sorb、OM和Res组分的镉含量较高，砂质粘土壤土中WsEx和Car组分的镉含量较高。添加磷作为磷酸单钙降低了WsEx和Sorb组分中镉的浓度，增加了Car、OM和Res组分中镉的浓度。磷的存在降低了那些容易释放到土壤溶液中的Cd的浓度(WsEx和Sorb)，它们将被植物吸收，从而减少了植物对镉的吸收。

Alluvial soils cover about 5% territory of Poland and they are an important part of the environment of fl oodplains and river valleys. These soils have long been studied by soil scientists around the world. The high school students also have a relatively high knowledge of them in comparison with other soil types. Information about them is readily available in textbooks and on the internet. Is this enough to make alluvial soils the driving force behind efforts to popularize soil science? The aim of this paper is to diagnose the state of knowledge about these soils among high school students of Kuyavian-Pomeranian region as well as the assessment of their suitability in the soil awareness raising. Querying geography textbooks and internet sources as well as a survey method were used as the main research methods. Information on alluvial soils is commonly found in geography textbooks and websites. The awareness of soil distribution within Kuyavian-Pomeranian voivodship is the highest for alluvial soils among all studied types of soils. Respondents correctly assess the value of these soils and can identify ways to increase soil awareness among the public. Among the respondents there is a conviction that there is a need for changes in soil science education, especially in the fi eld of extracurricular activities. Suggestions for such activities are included in this publication. The Year of Alluvial Soils is a good opportunity to introduce new solutions in the popularization of soil science on a regional and national scale.

This article aims to study the radioactivity of soils enriched with pyrogenic artefacts and the possible enhancement of radioactive background and the dose load on the population as a result of coal mining and electricity generation in mine-energetic region Pernik, Bulgaria. Content of major radionuclides responsible for radiation loading – 238 U, 232 Th, 40 K, their progenies 226 Ra and 210 Pb, and technogenic 137 Cs was determined in fi ve soil types representative for the region. Data show that the activity (Bq kg -1 ) of 238 U, 226 Ra, 232 Th and 40 K in studied soils slightly fl uctuates around average values in Bulgarian soils, accepted as background levels in this study. The activity of 210 Pb and 137 Cs was also comparable to that established in other uncontaminated soils. The mixing of materials and artefacts containing pyrogenic carbon (coal-clayey substrate occurring in the unproductive coal strata and slag produced in the local thermal power plant) during the formation of reclaimed soils increases the content of studied radioactive elements, but the highest levels are found in soils (Cam-bisols) enriched with soot. Thus, a typical anthropogenic enhancement of radiation background was observed but it is also not hazardous to the population. Gamma radiation emanating from studied soils is below the recommended values and vary from 0.23 to 0.57 for external hazard index, and from 0.29 to 0.61 mSv y -1 for outdoor annual effective dose. The established interlink between 210 Pb activity and pyrogenic carbon content show that 210 Pb could be used as a marker of the recent deposition of pyrogenic carbon formed during the coal combustion and other activities emitting pyrogenic carbon-containing aerosols.

The extraction of olive oil produces an enormous quantity of waste, such as olive mill wastewater (OMWW) and olive mill pomace (OMP), The majority of the agricultural wastes, including olive oil mill waste, are used as soil amendments due to their high nutritional value. The purpose of this study was to investigate the effects of the amendment with olive mill pomace from a 3-phase cold-pressed system on the characteristics of the soil pH, electrical conductivity (EC), and organic matter content (OM). The experiment was carried out using increasing rates of olive mill pomace (12.5%, 25%, 50%, 75%, and 100% w/w) plus the control untreated soil in microcosms under laboratory conditions. The results showed that the treatment of soil with olive mill pomace has a signi fi cant effect on soil properties (pH, EC, OM, OC, and CaCO 3 ) soil pH was decreased under OMP treatment, especially with high doses of PR4 and PR5, and the electrical conductivity of the soil (EC) was increased, as well as soil carbonate content. Moreover, the soil organic matter content and soil organic carbon content were highly increased under the treatment with OMP. As a result, we can consider the olive mill pomace as a soil fertilizer. Pretreatment of olive mill pomace to reduce acidic pH and salt content before use as a soil amendment is also recommended.

This study aimed to evaluate the long-term effects of wild fi re on nutrient distribution in a silver birch ( Betula pendula Roth) biomass. Two stands (post- fi re and control) of the same age (27 years) were studied in the Cierpiszewo Forest District (central Poland). The stands were located on Brunic Arenosols developed from aeolian sands. The soil and birches were sampled in 10 replicates per stand. The soil samples were taken from depths of 0–10, 10–20, 20–40 and 20–40 cm using a corer. Samples of fi ne roots, coarse roots, stemwood, stem bark, coarse branches, fi ne branches and leaves were taken from the trees. The basic soil characteristics were determined using standard proce-dures. In addition, the carbon (C), nitrogen (N), sulfur (S), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), manganese (Mn), copper (Cu) and zinc (Zn) contents were analyzed in the soil and biomass samples. The soils were strongly acidic and poor in the studied elements. The nutrient content in the biomass varied strongly among the organs. The most abundant elemental contents were usually in the leaves, followed by the fi ne roots and fi ne branches or bark. The lowest nutrient contents occurred in the stemwood. Statistically signi fi cant differences were recorded between the post- fi re and control stands for some elements. There were higher P, K and Zn contents in most of the biomass fractions in the post- fi re stand, as well as Mg and Mn in the roots and stemwood. The control stand had mostly higher contents of N and Ca. The effects of fi re on the Fe and Cu accumulations varied among the organs and was not clear for S. Generally, birch showed the highest bioaccumulation intensity for N and the lowest for Fe. Among all the studied nutrients, the bioaccumulation factors were usually the highest in the leaves and the lowest in the stemwood. It can be concluded that fi re is an important factor in in fl uencing nutrient management in silver birch stands, even a few decades after its occurrence.

The term “carbonate soils,” although relatively commonly used by soil scientists around the world, does not have a standardized qualitative and quantitative definition. It is often used interchangeably with “calcareous soils,” although it seems to cover not only limestone soils, but all soils containing carbonates, the origin of which may vary. Some authors, however, frequently use the term “calcium carbonate-rich soils” (Kowalska et al., 2017, 2019) and this refers to soils developed on parent material with a calcium carbonate content of 5% to 50% (Czermiński, 1955; Kowalska et al., 2019). Soil containing carbonates are found all over the world (Zamanian et al., 2016a). The carbonate content in solum may vary between 1% and more than 90% (Razzaghi et al., 2021). Their form may also vary. In the most basic sense, carbonates may be grouped as either primary (lithogenic) or secondary (pedogenic). Lithogenic carbonates, also called geogenic carbonates, are derived from the parent material of the soil – weathered carbonate rock such as limestone, marl, gaize, dolomite, etc. (Guo et al., * Methodological problems with the classifi cation and measurement of soils containing carbonates
“碳酸盐土壤”一词虽然被世界各地的土壤科学家相对普遍地使用，但并没有一个标准化的定性和定量定义。它经常与“钙质土壤”交替使用，尽管它似乎不仅包括石灰石土壤，而且包括所有含有碳酸盐的土壤，其来源可能各不相同。然而，一些作者经常使用“碳酸钙富土”一词(Kowalska等人，2017,2019)，这是指在碳酸钙含量为5%至50%的母质上发育的土壤(Czermiński, 1955;Kowalska et al.， 2019)。世界各地都发现含有碳酸盐的土壤(Zamanian et al.， 2016a)。solum中的碳酸盐含量可能在1%到90%以上之间变化(Razzaghi et al.， 2021)。它们的形式也各不相同。从最基本的意义上讲，碳酸盐岩可分为原生(造岩)和次生(造土)两类。成岩碳酸盐岩，又称地成因碳酸盐岩，是由土壤风化的碳酸盐岩母质如灰岩、泥灰岩、泥灰岩、白云岩等形成的(Guo et al.， *含碳酸盐土壤的分类和测量方法问题)

Recently, management of soil irrigated with low-quality water has become necessary to have a healthy crop. This research work aims to design the best management practices (BMP) to minimize drainage water hazards in the soil ecosystems. Based on the source of irrigation water, a column experiment was implemented on three soil samples that collected from three governorate in Egypt. The subsistence of enteric pathogens in soil irrigated with three types of low-quality water either sole sewage effl uent (Giza) or a mix of drainage and industrial effl uent (Kafr-el-sheikh) or drainage effl uent (Sinai) was monitored periodically for 90 days. The trailed soils were divided as: non inoculated cultivated (C) or inoculated cultivated with sole phosphate dissolving bacteria (T1) or Acidithiobacillus sp. (T2) or with a combination of both microorganisms (T3). Three common hyperaccumulator plants (Brassica napus, Plantago psyllium, and Plantago major) were cultivated separately in cultivated, inoculated soil trials in comparison to non-cultivated, non-inoculated control treatments (NC). Results section illustrates the removal pattern of fecal coliforms and Salmonella sp. in the trailed soil ecosystems, in response to different treatments during 90 days of experimental monitoring. The trailed remediation amendments, either in the single or combined application, followed by phytoremediation with three different phytoremediation plants, exhibited a positive effect in diminishing pathogenic bacteria in the three tested soil ecosystems, yet at varying degrees. The study concludes that, applied mixture of all treatments represented by choice of Plantago psyllium (as best phytoremediator plant) and combination of two remeditative bacterial inoculums (Acidithiobacillus and phosphate dissolving bacteria) in contaminated soil was selected as the BMP among the other applied treatments.

This research work aims to design the best management practices (BMP) to minimize drainage water hazards in the soil ecosystems. Based on the source of irrigation water, a column experiment was implemented on three soil samples that collected from three governorate in Egypt. The subsistence of enteric pathogens in soil irrigated with three types of low-quality water either sole sewage effl uent (Giza) or a mix of drainage and industrial effl uent (Kafr-el-sheikh) or drainage effl uent (Sinai) was monitored periodically for 90 days. The trailed soils were divided as: non inoculated cultivated (C) or inoculated cultivated with sole phosphate dissolving bacteria (T1) or Acidithiobacillus sp. (T2) or with a combination of both microorganisms (T3). Three common hyperaccumulator plants (Brassica napus, Plantago psyllium, and Plantago major) were cultivated separately in cultivated, inoculated soil trials in comparison to non-cultivated, non-inoculated control treatments (NC). Results section illustrates the removal pattern of fecal coliforms and Salmonella sp. in the trailed soil ecosystems, in response to different treatments during 90 days of experimental monitoring. The trailed remediation amendments, either in the single or combined application, followed by phytoremediation with three different phytoremediation plants, exhibited a positive effect in diminishing pathogenic bacteria in the three tested soil ecosystems, yet at varying degrees. The study concludes that, applied mixture of all treatments represented by choice of Plantago psyllium (as best phytoremediator plant) and combination of two remeditative bacterial inoculums (Acidithiobacillus and phosphate dissolving bacteria) in contaminated soil was selected as the BMP among the other applied treatments.","PeriodicalId":44772,"journal":{"name":"Soil Science Annual","volume":"22 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2022-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77144562","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}
