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. 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). Research is going on worldwide to enhance mineral weathering processes and to accelerate mineral carbonation reactions (Salek et al., 2013). The soil amendment is composed of the main material, amine treated lignite, bone meal, bran, soybean meal, and the other additives. Fertil. doi: 10.1016/j.envpol.2012.01.029, Luyckx, M., Hausman, J.

Moreover, the adequate Si supply through slag silicate fertilizer amendment causes competitive inhibition of As(III) uptake by crop plants (Meharg and Meharg, 2015). 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).

A combination of slag fertilizer and microbial remediation strategies could be proposed for effective remediation of soil contaminants. This material has the potential to amend poor soils. Effect of silicate slag application on wheat grown under two nitrogen rates. Slag-based silicate fertilizer has been widely used to improve soil silicon- availability and crop productivity. 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. These beneficial effects of slag fertilization largely rely on the changes in soil microbial habitats and microbial activities. Potential biotechnological strategies for the cleanup of heavy metals and metalloids. Mat. 4,985,060). 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. Iron oxidation coupled to denitrification can occur in anoxic soils, which can lead to N2O production (Melton et al., 2014); however, under conditions where Fe is highly available, the electrons donated by Fe(II) exceed the electron demand for N2O production, which leads to complete denitrification to N2 and thus a suppression of N2O emissions (Wang et al., 2016). Ag-Slag has proven its value as an agricultural liming material since the 1920's in all types of crop production and landscaping. Slag is a less expensive alternative to gravel and limestone aggregates. 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. Dan Gallagher October 12, 2018 at 1:07 pm. Likewise, the introduction of plant growth promoting bacteria possessing CA activity in agriculture could have the dual benefit of increased crop yield and CO2 sequestration.
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. Author information: (1)Institute of Agriculture and Life Sciences, Gyeongsang National University, Jinju 660-701, Republic of Korea. 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).

Common soil amendments include: Garden soil is a soil amendment for in-ground use rather than use in containers or raised beds. 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. furnace slag began to decrease sharply in the early 1970s. Effective utilization of organic amendments and slag builds soil fertility, improves plants resistance against disease, and it is important for sustainable agriculture. Soil amendment in order to obtain an optimal pH improves also the yields for long-term. }

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. Owing to its suitable chemical and mineralogical properties, slag fertilizer has been used as a stabilizing agent to minimize … Korea, Japan, Bangladesh, and China). 57, 236–266. Moreover, the land filled with disposed slag has become an important source of pollution of air, water, and soil, which further adversely affects vegetation and human health (Branca and Colla, 2012). B., and Kim, P. J. 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). Investigations on phosphorus recovery and reuse as soil amendment from electric arc furnace slag filters. View all
The potential effects of slag on crop plants have been described in the separate subheading and also shown in Figure 2. Anti-skid for winter roads. It has a texture full of holes. Korea, Japan, Bangladesh and China). (Luxembourg: International). doi: 10.1016/j.geoderma.2013.08.011, Das, S., Jeong, S. T., Das, S., and Kim, P. J.

In this perspective, we discuss the driving mechanisms of slag-microbe interactions in soil, and slag-microbe interaction effects on crop yield, greenhouse gas reduction, soil carbon storage, and heavy metal stabilization in contaminated soils. CALL FOR UP TO DATE PRICING & AVAILABILITY doi: 10.1016/j.agee.2008.04.014, Beerling, D. J., Leake, J. R., Long, S. P., Scholes, J. D., Ton, J., Nelson, P. N., et al. 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. (2009b). PLoS One 11, 1–15. The slag fertilizer amendment markedly affects the soil solution composition through acid–base, precipitation, and sorption reactions. Finer textured material is even better. (2015). 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. 44, No. Huang, B., Yu, K., and Gambrell, R. P. (2009). (2009a) reported that the silicate fertilizer amendment in no-tillage submerged paddies could improve the crop yield up to 47.2%. SPUPOPUPNO1. 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. The entry of heavy metals/metalloids into the food chain is a critical issue of current public health (Chand et al., 2015). 13, pp. Agric. Molasses acts as a soil amendment and is an excellent chelating agent … “Environmental aspects of the utilization of steel industry slags” in Proceedings of VII intenational conference on molten slags, fluxes and salts (Cape Town, South Africa: The South African Institute of Mining and Metallurgy). If the slag is not dangerous for the environment and public health, then the priority should be given to the use of recycled materials. Microb. Environ. The soil amendment is composed of the main material, amine treated lignite, bone meal, bran, soybean meal, and the other additives. As peat soil amendment, Indonesian steel slag enhanced growth and bole volume of Acacia cracicarpa grown on peat soil. With few exceptions, the required metals are divalent cations, including Ca2+, Mg2+, and Fe2+, and the most abundant cation source are silicate minerals.
