• Home vegetable gardeners need an easy-to-spread slag liming material. Emphasis has been given for further research to validate the proposed mechanisms associated with slag-microbe interactions for increasing soil quality, crop productivity, and mitigating environmental consequences. Wang et al. var fshowMsg = false; The soil amendment is composed of the main material, amine treated lignite, bone meal, bran, soybean meal, and the other additives. ... a reddish brown to black volcanic slag. 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. Higa describes a beneficial soil amendment consisting of coal ash and slag, to which 5 to 20 wt % zeolite is added, as well as optional microorganisms and a binder component. Soil salinity and pH were significantly higher for an amendment with both slag and biochar than the control in both the early and late paddies, and pH was significantly higher for a slag amendment in the late paddy. The slag fertilizer amendment markedly affects the soil solution composition through acid–base, precipitation, and sorption reactions. Steel slag can be considered a mineral amendment used to improve soil acidity, and also a source of calcium and magnesium. Front. Exp. Mixing materials into the slag to improve water retention. Humate increases water aggregates, infiltration, and percolating; benefits soil structure, enhances root growth, and reduces leaching, runoff and erosion. The by-product was selected as an alternative to commercial Fe oxides, which can decrease plant uptake, but they are expensive if used as amendments of contaminated arable soils. Intensive rice cultivation to meet the growing food demand chronically depletes Si from soil, thus degrades soil quality and decreases the crop yield (Branca and Colla, 2012). doi: 10.1016/j.jhazmat.2018.04.023. In addition, we discuss the problems and environmental concerns in using slag in agriculture. doi: 10.1038/nrmicro2439, Song, A., Fan, F., Yin, C., Wen, S., Zhang, Y., Fan, X., et al. Biol. Fertilizers made of slag are categorized as slag silicate fertilizer, lime fertilizer, slag phosphate fertilizer, and iron matter of special fertilizer (Ito, 2015). } Geoderma 271, 173–180. Received: 03 December 2018; Accepted: 27 May 2019; Published: 18 June 2019. 164, 73–80. Rev. (2012) reported that the silicate fertilization is not effective in reducing CH4 emissions in green manure amended paddy soils probably due to the enhanced decomposition of added organic matter by the silicate liming effect. These effects could be due to the shift in microbial metabolism and/or modification of microbial habitats. Molasses acts as a soil amendment and is an excellent chelating agent … There is an urgent need to evaluate the fate of soil carbon and carbon sequestration potential of slag fertilizer in field conditions. 10:1320. doi: 10.3389/fmicb.2019.01320. |, Driving Mechanisms of Slag-Microbe Interactions in Soil, Slag-Microbe Interaction Effects on Crop Yield, Slag-Microbe Interaction Effects on Greenhouse Gas Emissions, Slag-Microbe Interaction Effects on Soil Carbon Storage, Slag-Microbe Interaction Effects on Heavy Metal Stabilization in Contaminated Soils, Environmental Concerns About the Use of Slag in Agriculture, https://www.frontiersin.org/articles/10.3389/fmicb.2019.01320/full#supplementary-material, http://cdn.intechopen.com/pdfs/32571/InTech-Possible_uses_of_steelmaking_slag_in_agriculture_an_overview.pdf, http://www.nssmc.com/en/tech/report/nssmc/pdf/109-23.pdf, Creative Commons Attribution License (CC BY). Plant Sci. The use of slag fertilizer instead of agricultural lime (limestone) to increase soil pH would eliminate the dissolution of lime as an important source of agricultural CO2 emissions.

From the perspective of natural resource conservation, environmental protection, and human health safety measures, recycling of slag has drawn the attention of scientists, environmentalists, and policymakers in recent years. Articles, University of Southampton, United Kingdom. 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 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). Hiltunen, R., and Hiltunen, A. 'transitionIn' : 'elastic', SD wrote the manuscript. Kuhn et al. }); Steel slag is produced during the steel making process where, after air cooling, a dense rock material is processed and sized into specific products suitable for diverse applications. PRICES SUBJECT TO CHANGE WITHOUT NOTICE. Nat. 44, No. The invention relates to a soil amendment prepared from biogas residue and wormcast as main material and a preparation method of the soil amendment, which belongs to the technical field of recycling of organic fertilizer and agricultural waste resource. Different response of silicate fertilizer having electron acceptors on methane emission in rice paddy soil under green manuring. The golfing public needs to be aware that there are a few environ- mental consequences when providing quality playing surfaces for the game. Agriculture significantly contributes to the emission of methane (CH4) and nitrous oxide (N2O), which are two of the most important greenhouse gases responsible for global warming (Das and Adhya, 2014). 'scrolling' : 'auto', Some studies suggest slag fertilizer decreases N2O emissions (Susilawati et al., 2015; Wang et al., 2015), while other studies suggest slag fertilizer increases N2O emissions (Huang et al., 2009; Liu et al., 2012). (2008). and plants were conducted to measure vanadium toxicity in different vanadium soil treatments; freshly spiked, aged and blast furnace slag (800 mg V kg-1). Plant Nut. slag can be considered a mineral amendment used to improve soil acidity, and also a source of calcium and magnesium. Sweetens sour soils. In a recent study, Song et al. Microbiol.
