Plants 4, 138–147. *Correspondence: Pil Joo Kim, [email protected], Front. This study examined the effects of applying . Soil management. Higher grain yields in response to silicate fertilization could be attributed to the fact that Si preferentially deposits in the epidermal cell wall and increases physical strength of leaves and leaf-sheaths and help plants to sustain yield by counteracting various biotic and abiotic stresses and increasing plant biomass (Luyckx et al., 2017). In addition, long-term experiments in Germany showed that steel slag fertilizer amendment did not increase bio-available Cr content in soil and Cr uptake by plants (Hiltunen and Hiltunen, 2004). Key Laboratory of Plant‐Soil Interactions, Ministry of Education, Center for Resources, Environment and Food Security, China Agricultural University, Beijing, 100193 PR China. Effect of silicate slag application on wheat grown under two nitrogen rates. Silicon nutrition increases grain yield, which, in turn, exerts a feed-forward stimulation of photosynthetic rates via enhanced mesophyll conductance and alters primary metabolism in rice. The main objective of the project was to enhance food security, improve soil fertility, and mitigate greenhouse gases from agriculture using integrated cropping-livestock systems in … Waste Manag. Rev. Plant Sci. Crops sold on markets ('cash crops') are an integral part of strategies to improve food security at farm household level in developing countries. 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). Unlike CH4 emissions, the slag fertilizer effects on N2O emissions from rice cropping systems are contradictory. The slag can be mixed with livestock wastes to make compost, so that both slag and livestock waste can be effectively utilized in agriculture. doi: 10.1007/s00374-011-0637-2, Liang, Y., Sun, W., Zhu, Y. G., and Christie, P. (2007). Fertilizers made of slag are categorized as slag silicate fertilizer, lime fertilizer, slag phosphate fertilizer, and iron matter of special fertilizer (Ito, 2015). The effects of slag fertilizer amendment on the biogeochemical cycling of soil elements that are regulated by soil microbes need to be investigated. You are seeing a free-to-access but limited selection of the activity Altmetric has collected about this research output. 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 UN’s Sustainable Development Goal SDG 2 aims to ‘end hunger, achieve food security and improved nutrition and promote sustainable agriculture’. Slag fertilizers, in particular, iron/steel slag fertilizers are rich in iron. ole in safeguarding food security.

Microbiologists are investigating how the soil microbiome can be harnessed as a tool for sustainable agricultural intensification. 353, 236–243. D. Achilias (InTech). Mineral carbonation of CO2. 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).
