The editor and reviewers' affiliations are the latest provided on their Loop research profiles and may not reflect their situation at the time of review. Environ. Wang et al. 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. Field Crops Res. (2009). Mineral carbonation of CO2. Among fertilizers made from slag, the use of silicate fertilizer, particularly in rice cropping systems has been gaining awareness and demand (Meharg and Meharg, 2015). Summary of potential effects of slag on crop plants. Soils 53, 627–638. 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 … Steel slag presented an Amendment Neutralization Potential very high (ANP = 114%) reported to the content of calcium oxide and magnesium oxide. All Rights Reserved. They represent the authors’ point of view. Besides silicate fertilizer, lime fertilizer has been widely used in acidic soil to neutralize the soil, which helps plants to protect themselves against soil pathogens. (2009b).

Most importantly, lime and silicate always exist in the steelmaking slag. It has a texture full of holes. 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 Increases in N2O emissions with Si fertilization have been attributed to: (1) Si fertilization acting to lower soil C decomposition, which would alleviate immobilization of fertilizer N thereby making more mineral N available to nitrification and denitrification; and (2) Si fertilization improving soil pH and Eh, which are two factors important to N2O emissions (Huang et al., 2009; Liu et al., 2012). In fact, at the system level, soil microorganisms play a vital role in virtually all ecosystem processes and provide ecosystem services crucial for the maintenance of soil quality and productivity (Das et al., 2017). doi: 10.3390/agronomy8080135, Wang, W., Sardan, J., Lai, D., Wang, C., Zeng, C., Tong, C., et al. Mineral carbonation of CO2 (mineral CO2 sequestration) occurs spontaneously on geological time scales and has a high potential for CO2 sequestration (Oelkers et al., 2008). Slag amendment is a material rich in silicon produced from manufactured steel. A consecutive early rice-late rice rotation experiment was conducted to test the impacts of steel slag on soil pH, silicon availability, rice growth and metals-immobilization in paddy soil. 'overlayShow' : true, Wang et al. SPUPOPUPNO1. This material has the potential to amend poor soils. Effective utilization of organic amendments and slag builds soil fertility, improves plants resistance against disease, and it is important for sustainable agriculture. 'resizeOnWindowResize' : true, Korea, Japan, Bangladesh and China). The effects of slag fertilizer amendment on the biogeochemical cycling of soil elements that are regulated by soil microbes need to be investigated. Steel slag amendment is becoming an effective method to increase the soil fertility, stabilize rice production and reduce greenhouse-gas emissions in Asiatic paddy fields (i.e. Silicon and plants: current knowledge and technological perspectives. (2014). Steel slag can be considered a mineral amendment used to improve soil acidity, and also a source of calcium and magnesium. The slag fertilizer amendment markedly affects the soil solution composition through acid–base, precipitation, and sorption reactions. Next-generation sequencing technologies for environmental DNA research. (2009). Korea, Japan, Bangladesh, and China). Nat. Steel slag can be considered a mineral amendment used to improve soil acidity, and also a source of calcium and magnesium. doi: 10.1016/j.envpol.2006.06.008, Liu, S., Zhang, L., Liu, Q., and Zou, J. Lastly, we discuss environmental concerns about the use of slag in agriculture and the future perspectives. (2008). doi: 10.1080/00380768.2015.1041861, Wang, M., Hu, R., Zhao, J., Kuzyakov, Y., and Liu, S. (2016). Due to the high reactivity of CaO and MgO and high pH (i.e., 12.5) of Ca(OH)2, repeated application of slag may make the soil excessively alkaline, which may decrease the bioavailability and uptake of macronutrients such as P and micronutrients such as Fe, Cu, and Zn by the plant and likely hinder plant growth and productivity (Chand et al., 2015). 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. The golfing public needs to be aware that there are a few environ- mental consequences when providing quality playing surfaces for the game. Cumulative CH4emission was lower for the slag and slag + biochar amendments than the control in early paddy by—34.1%. Journal of Environmental Science and Health, Part A: Vol. 'centerOnScroll' : true, 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.

H.R. • Home vegetable gardeners need an easy-to-spread slag liming material. There are only few reports concerning the effects of the slag fertilizer amendment on carbon sequestration in cropping systems. Impacts of steel-slag-based silicate fertilizer on soil acidity and silicon availability and metals-immobilization in a paddy soil. Rev. Chemosphere 74, 481–486. Waste amendments, such as steel slag and biochar, have been reported as a strategy for improving soil fertility, crop productivity, and carbon (C) sequestration in agricultural lands. 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). Effect of silicate slag application on wheat grown under two nitrogen rates. The main concerns regarding the use of slag in agriculture are the potential for heavy metal accumulation in soil and the risks related to liming of soil (Chand et al., 2015). Heavy clay soils don’t produce the healthiest plants and are usually amended with a material to lighten, aerate and help retain water. Since slag fertilizers are a rich source of silicon minerals and alkaline in nature, their application in agricultural soil may potentially increase soil carbon sequestration. Dan Gallagher October 12, 2018 at 1:07 pm. The steel-making slag (SMS), a by-product of steel manufacturing process with an alkaline pH (11-12) and high amount of iron (Fe) and calcium (Ca) oxides, was used to reduce arsenic (As) phytoextractability. Utilization of steelmaking slag in Japan and the recent progress towards soil amendment . 1476-1483. Agric. Plants 4, 138–147. 6. Likewise, the iron matter of special fertilizer has been used to mitigate the toxicity of heavy metals in soil as well as in the plant. However, information regarding the subsequent effects of steel slag and biochar on C cycling and the underlying microbial mechanisms in paddy soils remains limited. 10, 975–984. }); Steel slag (SS) is a fertilizer amendment with a high concentration of calcium oxide, and thus capable of raising substrate pH similar to dolomitic lime (DL). (2017). 29, 2759–2764. It is also used in soil stabilization and as filler in asphalt and other products that are widely used in construction. 2.2 Fertilizers made from blast furnace slag and steelmaking slag Nat.

The effect of Indonesian steel slag on paddy rice grown on peat soil was significantly better than that of on mineral soil. Figure 1. After being processed, steel slag can be used as smelter flux, cement raw material, construction aggregate, foundation backfill, railway ballast, road pavement, brick, slag fertilizer and soil amendment, etc. Iron oxidation affects nitrous oxide emissions via donating electrons to denitrification in paddy soils. In recent years, extensive research has been conducted to obtain a mechanistic understanding of the contribution of microbial communities to ecosystem functioning under various agronomic management practices. Unlike CH4 emissions, the slag fertilizer effects on N2O emissions from rice cropping systems are contradictory. Slag is a less expensive alternative to gravel and limestone aggregates. Articles, University of Southampton, United Kingdom. 8:411. doi: 10.3389/fpls.2017.00411, Meharg, C., and Meharg, A. The slag fertilizer amendment markedly affects the soil solution composition through acid–base, precipitation, and sorption reactions. According to Nippon Slag Association’s statistics on the use of slag in 2012, the total consumption of blast furnace and steelmaking slags for fer-tilizer and soil amendment was 260 000 tons. The slag can be mixed with livestock wastes to make compost, so that both slag and livestock waste can be effectively utilized in agriculture. 'overlayOpacity' : 0.3, In this study, the ground granulated blast-furnace slag (GGBS) is 43 proposed as a soil amendment to reduce plant Cd availability and therefore increase transpiration 44 induced suction. In recent years, several studies have revealed that the slag-based fertilizer amendment in agriculture has great promise to improve crop productivity (White et al., 2017; Gwon et al., 2018), alleviate soil acidification (Ning et al., 2016), mitigate greenhouse gas (GHG) emissions (Wang et al., 2015; Gwon et al., 2018), and stabilize heavy metals in contaminated soils (Ning et al., 2016), which turns it into a high value added product for sustainable agriculture. Contain iron, calcium, magnesium and zinc. 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. Slag phosphate fertilizer has been used to provide adequate phosphorus to the plant, which improves plant growth and fruiting. While evaluating the slag amendment, effects on agriculture and environment, the potential risks, socio-economics, techno-economics, and ethics should be assessed. Front. The term “slag” is used in the specifications of slag silicate fertilizer and slag phosphate fertilizer in the Fertilizer Control Law. Road Ash. A neutralising value similar to limestone, for correcting pH, ... DE is not a fertiliser but enables soils and fertilisers to work more efficiently, so is an excellent soil amendment at all times, complementing the use of traditional fertilisers and making more ecological and economic sense. OUT OF PRODUCTION UNTIL THE FALL ITEM #04S05 DESCRIPTION:Nutrient-rich soil amendment that has excellent soil liming properties. Plant Nut. Composted cattle manure increases microbial activity and soil fertility more than composted swine manure in a submerged rice paddy. Mineral carbonation reactions require combining CO2 with metals to form stable carbonate minerals. Besides, the slag fertilizer amendment may induce changes in soil enzyme activities that affect soil nutrient mobilization and microbial dynamics. Basic Slag. Importantly, soil amendments composed of steelmaking slag can provide an effective way to supply the required elements for soil recovery at low cost. LF slag (slag from secondary treatment of steel) occurs in the form of a powdery material. Carbon dioxide sequestration in soils is well recognized as an avenue to mitigate climate change. Environ. 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. Exp. doi: 10.1016/j.wasman.2009.05.018, Ali, M. A., Lee, C. H., Lee, Y. Front. doi: 10.12944/CWE.10.3.29, Das, S., and Adhya, T. K. (2014). 'showCloseButton' : true, However, to secure the reliability of the slag as fertilizer, it is quite necessary to conform to the regulations on hazardous heavy metals provided by the Fertilizer Control Law and the soil environmental standards provided by the Basic Law for Environmental Pollution Control. On the other hand, steelmaking slag is an inevitable by-product of iron and steel industry, which has a very large annual production. 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. doi: 10.1016/j.envpol.2012.01.029, Luyckx, M., Hausman, J. F., Lutts, S., and Guerriero, G. (2017). The stabilization technique aims at reducing heavy metal and metalloid (e.g., As, Cr, Cu, Pb, Cd, and Zn) bioavailability in contaminated soil. Some soil amendments also add nutrients to the soil, help retain moisture and help maintain the correct pH balance. Finer textured material is even better. (2018). jQuery(document).on('click', '#Citation27', function(event){ //jQuery(document).on('click', '#Citation27', function(event){ Cumulative CH4 emission was lower for the slag and slag + biochar amendments than the control in early paddy by—34.1%. Several studies reveal that metal contamination in soil and metal uptake by plants are not adversely affected by short-term slag fertilizer amendment in cropping systems (Ali et al., 2008, Gwon et al., 2018). CALL FOR UP TO DATE PRICING & AVAILABILITY The extent of CH4 emissions reduction depended on the slag fertilizer type, rate of application, soil type, and agronomic practices (Supplementary Table S1). Ali et al. 8, 779–790. Environ. Although mineral carbonation is thermodynamically favorable, it proceeds very slowly (Oelkers et al., 2008). Bot. 196, 752–762. Slag fertilizers, in particular, iron/steel slag fertilizers are rich in iron. 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). Microb. These beneficial effects of slag fertilization largely rely on the changes in soil microbial habitats and microbial activities. Specifically, we studied the effects during the growing season of different amounts of steel slag amendments on soil nutrient concentrations and C:N, C:P and N:P ratios in rice leaves, stems and With advances in omic techniques, soil microbial communities and community-level molecular characteristics have been exploited as early indicators of ecosystem processes for sustainable soil management and agricultural productivity (Shokralla et al., 2012). A Comparison of Blast-Furnace Slag and Limestone as a Soil Amendment, Yolk, Harding and Evans, Ohio Agricultural Experiment Station, Research Bulletin 708, November 1952. Trends Biotechnol. (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. The recent advances in omic techniques, e.g., high-throughput sequencing, metatranscriptomic analysis, and DNA/RNA-based stable isotope probing (SIP) will no doubt be imperative to uncover the hidden dimensions of slag-microbe interactions in ecosystem functioning. (2012). The potential effects of slag on crop plants have been described in the separate subheading and also shown in Figure 2. Using steel slag as amendment for acid soils can be considered a potential and significant environmental risk, which is why the whole process of amendment must be conducted in terms of environmental protection. No. Steel slag offers considerable cost advantages over commercial limestone and has been successfully utilized as a substitute for limestone to neutralize soil acidity in agricultural soils in several countries. furnace slag began to decrease sharply in the early 1970s. jQuery(document).ready(function() { Steel slag can be considered a mineral amendment used to improve soil acidity, and also a source of calcium and magnesium. To be cited: AgroLife Scientific Journal. Front. Research is going on worldwide to enhance mineral weathering processes and to accelerate mineral carbonation reactions (Salek et al., 2013). Understanding the effects of slag fertilizer on soil microbial communities and functions is essential to address some critical agro-environmental issues, such as whether the slag fertilizer amendment would be useful to increase crop productivity, reduce GHG emissions, increase soil carbon sequestration, and stabilize heavy metals in contaminated soils. ... Used in place of straw for seeding grass or soil amendment. Ali et al. 109. It is well recognized that the enzyme carbonic anhydrase (CA) participates in silicate weathering and carbonate formation and thus plays an important role in the biomemetic CO2 sequestration (Bose and Satyanarayana, 2017). Nat. Owing to its suitable chemical and mineralogical properties, slag fertilizer has been used as a stabilizing agent to minimize … furnace slag began to decrease sharply in the early 1970s. (2009b) showed that 4 mol of Fe3+ prevent the generation of 1 mol of CH4. Moreover, silicate fertilizer amendment can increase root biomass and O2 transport from the plant to root by enlarging arenchyma gas channels (Liang et al., 2007), which in turn suppresses CH4 production and stimulates CH4 oxidation. Owing to the contradictory results, the mechanism underlying N2O emissions and changes in the genetic potential of nitrifying and denitrifying bacteria under slag fertilization needs further investigation. AKA: Compost. Comprehensive utilization of steel slag can lead to enormous economic and social benefits. 44, No. The proposed mechanisms of slag-microbe interactions need to be experimentally verified and intensive research needs to be conducted to explore the microbial role in soil processes and agricultural productivity. (2006), however, revealed that the long-term application of converter slag significantly increased Cr and V contents in the cultivated layer of soil. Using steel slag as amendment for acid soils can be considered a potential and significant environmental risk, which is why the whole process of amendment must be conducted in terms of environmental protection. 13, pp. 7:303. doi: 10.3389/fpls.2016.00303, Ning, D., Liang, Y., Liu, Z., Xiao, J., and Duan, A. 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. Iron acts as an alternative electron acceptor in anoxic soil and its application decreases CH4 emissions by stimulating iron-reducing bacteria at the expense of methanogens (Gwon et al., 2018). The proposed mechanism of slag-microbe interactions in soil. With the increase in population, the available land to dispose of large amounts of slag in landfill sites is reduced and the disposal cost is becoming increasingly higher. • Farmers use Ag-Slag for maximum yields of cultivated crops and pasture.
