Slags contain traces of heavy metals, but the concentrations of heavy metals might not be enough to pose environmental risks (Gwon et al., 2018); however, it is believed that the long-term application of slag fertilizer in agriculture may accumulate heavy metals/metalloids in soil and may cause health risks. 44, No. Initially, each soil type has a certain level of acidity depending on the composition, the natural vegetation, the amount of rainfall and various other factors that cause changes in soil pH over time. ... Used in place of straw for seeding grass or soil amendment. Slag amendment is a material rich in silicon produced from manufactured steel. 7 Figure 5: Comparison between the annual utilization as fertilizer and the total production amount for steelmaking slag 'overlayOpacity' : 0.3, (2006), however, revealed that the long-term application of converter slag significantly increased Cr and V contents in the cultivated layer of soil. Since the mechanisms of slag-microbe interactions in soil are still not clear, this perspective focuses on the synthesis of several possible mechanisms based on published research. Air-Cooled Blast Furnace Slag : Asphalt aggregate Concrete/masonry aggregate Insulation/mineral wool Cement manufacturing raw material Agriculture/soil amendment Fill Roof aggregate Railroad ballast Glass manufacture Gabions/rip rap Environmental applications - filter media Pelletized Blast Furnace Slag doi: 10.12944/CWE.10.3.29, Das, S., and Adhya, T. K. (2014). While in the past, steel-making processes were exclusively designed for the production of specific quality and quantities of iron and steel, one of today’s goals for steel making is to design and develop technologies to produce high-quality slag according to the market requirements.

Institute of Multidisciplinary Research for Advanced Materials, Tohoku University, Japan. Slag consists mostly of mixed oxides of elements such as silicon, sulfur, phosphorus, and aluminum, and products formed in their reactions with furnace linings and fluxing substances such as limestone (Yildirim and Prezzi, 2011; Piatak et al., 2015). Copyright © 2019 Das, Kim, Hwang, Verma and Kim. (2018). (2015). The shift in soil microbial community and activities in response to slag fertilizer amendment may depend on the type of slag fertilizer (e.g., silicate fertilizer, lime fertilizer, slag phosphate fertilizer, and iron matter of special fertilizer), which modify soil properties and soil microbial habitats. jQuery('.Citation27').fancybox({ Exp. Plants 4, 138–147. furnace slag began to decrease sharply in the early 1970s. 57, 236–266. It can be used in potting soils and bed preparation for all landscaping and food crops. H.R. This is a garden supplement. It typically involves the dissolution of silicate minerals and subsequent precipitation of stable carbonate minerals (e.g., CaCO3, MgCO3, and FeCO3). Khan Department of Soil, Water & Environment, Faculty of Biological Sciences University of Dhaka, Dhaka 1000, Bangladesh. Geoderma 213, 185–192. Finer textured material is even better. The interplay of microbially mediated and abiotic reactions in the biogeochemical Fe cycle. Sweetens sour soils. Application of PTC slag as acid soil amendment will reduce the demand of P fertilizer, and even in high dosage can meet the P demand of komatsuna plant.Chemical properties of Pretreatment center slag (PTC-slag) were analyzed and compared to … Impacts of Basic Slag, Aggregate Size and Groundwater Levels for the Amendment of Acid Sulfate Soils in Relation to the Production of Mustard in a Simulation Study Md.

There are several examples, as follows: as can be stabilized by sorption on Fe oxyhydroxide and also by the formation of amorphous Fe(III) arsenates; Cr can be stabilized by the reduction from more mobile and toxic Cr(VI) to less toxic and stable Cr (III); Cu can be stabilized by precipitation of Cu carbonates and oxyhydroxides, iron exchange and formation of ternary cation-anion complexes on the surface of Fe and Al oxyhydroxides; and Pb and Zn can be immobilized by phosphorus amendments (Branca and Colla, 2012). Avilable at: http://www.nssmc.com/en/tech/report/nssmc/pdf/109-23.pdf. The influence of slag fertilizer on the soil microbiome are diverse and the possible mechanisms of slag-microbes interactions can be as follows: (1) slag fertilizer supplies nutrients not only to the plant but also to soil microorganisms; (2) slag fertilizer modifies soil microbial habitats by improving soil properties (e.g., increasing soil pH) (Gwon et al., 2018), which is essential for nutrient mobilization and microbial growth; (3) silicate fertilizer increases plant photosynthesis (Detmann et al., 2012) and likely increases belowground carbon allocation through root exudates, which eventually triggers soil microbial proliferation and activities; and (4) steel slag enhances heavy metal immobilization in soil (Ning et al., 2016) and thus reduces their bioavailability and toxicity to microbes.
