“…This could be probably due to the excess of mineral elements present in high amount in the D2 concentration of slag (20 g slag/ kg soil) that could become toxic to the development of wheat plants (Wang & Cai, 2006). Other researches showed a significant increase in growth and biomass accumulation for low rates of slag, while increasing application rates of slag did not improve the growth (Cai et Islam et al (2022) showed that the high rates of slag application in the soil led to a huge accumulation of Fe and decreased bacterial biomass in the soil, which could create a poor assimilation of nutrients and be a source of inhibition of plant growth. In contrast, application of steel slag to agricultural land can provide potential benefits for soils in the form of increased availability of Ca and P (Yang et al, 2019).…”

“…(2006) and Das et al (2019) have assessed the agronomic utility of steel slag as a fertilizer or as a liming material. Different types of steel slag had a good effect on crop output, but the effect varied depending on the plant species, type of soil, or climate (Das et al, 2020;Islam et al, 2022). Iron and steel slags were used in the pot experiments, which showed an increase in corn dry matter yield and Fe uptake for moderate rates of slag without having any negative phytotoxic consequences (Wang & Cai, 2006).…”

For a modern agricultural, the search for sustainable practices to increase productivity is fundamental. Steel slag have been studied for their potential use in agriculture. These substances present a great possibility of agricultural applications since they are rich in nutrients, which enhance plant uptake. In this regard, the effect of steel slag based-fertilizer was investigated in the greenhouse durum wheat cultivation in pots under salt-stress conditions. Two slag doses: 10 g slag/ kg soil (D1) and 20 g slag/ kg soil (D2) were evaluated under no salt-stress (0 mM NaCl) and salt-stress conditions (100 mM NaCl) for salinity stress mitigation. Morpho-physiological and biochemical parameters of wheat were measured and compared to the different treatments. Wheat exposure to salinity decreased its biomass, stomatal conductance, efficiency of photosystem II, protein content and increased total soluble sugars, hydrogen peroxide (H2O2) and malondialdehyde (MDA) contents. Amended plants with 10 g slag/ kg soil (D1), led to a significant improve in biomass with an increase of shoot and root dry weights (133% and 400% respectively), stomatal conductance (22 %), soluble sugars (14 %) and protein content (158%) under salinity conditions as compared to the control treatment 0 g slag/ kg soil (C), indicating a positive influence on durum wheat plants. However, soil enrichment with 20 g slag/ kg soil (D2) decreased plant growth parameters and presented the highest levels of H2O2 and MDA contents compared to the control and treatment D1 after three months of cultivation under salt-stress. This study supports the hypothesis of the application of slag at lower dose improve productivity of durum wheat and mitigate salinity stress.

Clubroot is a disease in cruciferous plants caused by the soil-borne pathogenPlasmodiophora brassicae. This pathogen rapidly spreads in soil, and plant growth is inhibited by infection with spores. In this study, the development of clubroot disease inBrassica rapavar. perviridis was investigated in different soil environments (chemical and organic soils). The bacterial biomass and diversity of the soil and roots were also analyzed in both chemical and organic soils. Bacterial biomass and diversity in the organic soil were higher than those in the chemical soil. The disease severity of plants cultivated in organic soil was lower than that in chemical soil. The number of endophytic bacteria in the roots decreased when the plants were infected withP. brassicaein both soil types. Higher bacterial biomass in the soils and roots appeared to reduce the infection ofP. brassicae.ImportancClubroot is a major disease of cruciferous plants caused by soil borne pathogenPlasmodiophora brassica.Pesticides are applied in the soil during cultivation for the inhibition of clubroot disease, which demise soil microbiome. Therefore, eco-friendly control methods are required for sustainable cultivation. Soil management is an important strategy to inhibit clubroot disease severity. In this study, the occurrence of clubroot disease inB.rapawere compared in two distinct soil environments (chemical and organic). Results show infection rate increased with the increase of spore number for both chemical and organic soil environments. However, the diseases severity was lower in plants cultivated in organic soil. The higher endophytic bacterial biomass and diversity seems to be linked for the disease inhibition in organic plants. These findings suggest a sustainable soil management process to reduce clubroot disease prevalence. Application of organic fertilizers in commented soils could substantially reduce clubroot disease severity in the plants.

“…The efficient disposal of steel slag has always been a challenge faced by the steel industry. In recent decades, steel slag has been applied in many fields, mainly involving wastewater purification [17], sewage sludge stabilization [18,19], carbon sequestration [20,21], agriculture utilization [22], cement and concrete production [23,24], road construction [25,26], etc. Recycling steel slag in road construction is very attractive as the high consumption of materials in road construction can accelerate the disposal of solid waste.…”

Recycling steel slag into asphalt concrete is an important way to save natural resources and protect the environment. The high asphalt absorption and adsorption and the sensitivity of steel slag aggregate (SSA) to the combined damage of temperature and moisture (volume expansion and poor durability under freeze-thaw cycle damage) still pose risks for the use of SSA in asphalt concrete. It is urgent to develop new utilization methods of steel slag. With this in mind, the material properties of steel slag powder (SSP) and performance characteristics of asphalt concrete incorporating SSP filler were evaluated in this research. The SSP was prepared in the laboratory by grinding steel slag with a particle size of 2.36–4.75 mm. Firstly, the material properties of SSP including the specific surface area, particle gradation, apparent density, chemical compositions, and thermal stability were analyzed. Steel slag (2.36–4.75 mm) and common limestone powder (LP) filler were used as control groups. The grindability of steel slag and the advantages of using SSP as a filler in asphalt concrete were preliminarily analyzed based on the test results of material properties. Then, the Superpave method was used to design asphalt concrete incorporating SSP and LP. Considering that steel slag is sensitive to the combined damage of temperature and moisture, the main engineering performance of asphalt concrete after the combined damage of temperature and moisture was evaluated to further reveal the feasibility of using SSP as a filler. Two combined damage modes, namely hot water damage and freeze-thaw cycle damage, were applied. Results suggest that although the steel slag is more difficult to grind compared to limestone particles, grinding steel slag into SSP has improved the uniformity of its material properties. Good uniformity of material properties, high alkalinity, and excellent thermal stability of SSP give it some advantages in its application in asphalt concrete. Although the freeze-thaw cycle damage has a slightly more significant effect on the engineering performance of asphalt concrete than hot water damage, compared to the asphalt concrete with LP filler, even after freeze-thaw cycle damage for three cycles asphalt concrete incorporating SSP still possesses comparable or better volume stability, mechanical performance, high-temperature deformation resistance, low-temperature crack resistance, fatigue crack resistance, and fatigue durability.
