Environ. The slag fertilizer amendment markedly affects the soil solution composition through acid–base, precipitation, and sorption reactions. Identification and elucidation of functional roles of keystone soil microbes that sustain plant health and productivity under slag fertilization could provide a technological breakthrough for a sustainable use of slag in agricultural productivity. This material has the potential to amend poor soils. Effects of steel slag application on greenhouse gas emissions and crop yield over multiple growing seasons in a subtropical paddy field in China. 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. 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. Author information: (1)Institute of Agriculture and Life Sciences, Gyeongsang National University, Jinju 660-701, Republic of Korea. 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. Slag amendment is a material rich in silicon produced from manufactured steel. jQuery(document).ready(function() { Slag. In a recent review it is postulated that farming with rock could have a great promise in sequestering carbon in soils (Beerling et al., 2018). 353, 236–243. 21, 1794–1805. Steel slag amendment is becoming an effective 22 method to increase the soil fertility, stabilize rice production, and reduce greenhouse-gas 23 emissions in Asiatic paddy fields (i.e. Mixing materials into the slag to improve water retention. 'hideOnOverlayClick': false, Owing to its high Si content, the use of slag as silicate fertilizer is gaining demand. If the slag is not dangerous for the environment and public health, then the priority should be given to the use of recycled materials. Bot. This aggregate product can be used on driveways but cannot be covered with black top or concrete. --> doi: 10.1016/j.geoderma.2016.02.022, Wang, W., Lai, D., Abid, A., Neogi, S., Xu, X., and Wang, C. (2018). 109. Slag-based silicate fertilizer has been widely used to improve soil silicon- availability and crop productivity. Lastly, we discuss environmental concerns about the use of slag in agriculture and the future perspectives. OUT OF PRODUCTION UNTIL THE FALL ITEM #04S05 DESCRIPTION:Nutrient-rich soil amendment that has excellent soil liming properties. Black in color. Moreover, the adequate Si supply through slag silicate fertilizer amendment causes competitive inhibition of As(III) uptake by crop plants (Meharg and Meharg, 2015). 1476-1483. 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. AKA: Compost. 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). (2006), however, revealed that the long-term application of converter slag significantly increased Cr and V contents in the cultivated layer of soil. This paper refersto the selection of an agriculture lime material to be used in experiments on acidity correction of an acid soil. PRICES SUBJECT TO CHANGE WITHOUT NOTICE. We studied the relationships of steel slag amendment with plant–soil … }); Next-generation sequencing technologies for environmental DNA research. 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. 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). 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. 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). Iron oxidation affects nitrous oxide emissions via donating electrons to denitrification in paddy soils. D. Achilias (InTech). Studies conducted in Korea, Japan, China, Indonesia, and Bangladesh indicated the potential of slag fertilizer amendment to decrease CH4 emissions by 0.6–56.0% from lowland rice paddies (Supplementary Table S1). 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. 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. 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. 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. Nat. Exp. They represent the authors’ point of view. 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. This is a garden supplement. Although mineral carbonation is thermodynamically favorable, it proceeds very slowly (Oelkers et al., 2008). 'resizeOnWindowResize' : true, Comprehensive utilization of steel slag can lead to enormous economic and social benefits. Biol. The slag fertilizer amendment markedly affects the soil solution composition through acid–base, precipitation, and sorption reactions. There are only few reports concerning the effects of the slag fertilizer amendment on carbon sequestration in cropping systems. Contain iron, calcium, magnesium and zinc. (2015). Plants 6, 1–14. It can be postulated that slag fertilizer amendment not only increases soil nutrients per se, but also enriches soil microorganisms that have a beneficial role in nutrient mobilization (e.g., carbon and nitrogen mineralization, phosphorus solubilization, nitrogen fixation, etc.). Unfortunately, few studies have focused specifically on understanding the changes in soil microbial community and function under slag fertilizer amendment in cropping systems. (2008). 10:1320. doi: 10.3389/fmicb.2019.01320. Description Soil amendments are organic and inorganic materials added to soil to improve it quality and chemistry for plants growth. Coal gasification fine slag (CGFS), which is the by-product of entrained-flow coal gasification, has superior properties, such as a large surface area, a broad pore size distribution, and a high content of carbon. Elements 4, 333–337. production. As peat soil amendment, Indonesian steel slag enhanced growth and bole volume of Acacia cracicarpa grown on peat soil. Biol. Paddy soil contamination by cadmium (Cd) and arsenic (As) is a great concern. All Rights Reserved. We studied 24 the relationships of steel slag amendment with plant-soil …
