LD steel slag as fertilizer in agriculture. Steel LD slag can also be used in fertilizers for agricultural applications (Das et al., 2007). The efforts have been made in Tata steel that LD slag after grinding to 300 mesh, can be used as a soil conditioner in paddy field, tea gardens etc (Basu et al., 2002).

The Comprehensive Utilization of Steel Slag in

Slags are calcium and magnesium silicates, which show neutralizing action due to SiO 3 2− base . Additionally, steel slags have been used as a low-cost source to supply Si to rice plants . In China, the first steel slag fertilizer program invested by Taiyuan Iron and Steel Group and Harsco Corporation of the USA started building in 2011 .

What is Slag? (with pictures)

Like other industrial byproducts, slag actually has many uses, and rarely goes to waste. It appears in concrete, aggregate road materials, as ballast, and is sometimes used as a component of phosphate fertilizer.

Effects of Slag

Jul 18, 2014Jul 18, 2014It is well documented that slag-based silicon fertilizers have beneficial effects on the growth and disease resistance of rice. However, their effects vary greatly with sources of slag and are closely related to availability of silicon (Si) in these materials. To date, few researches have been done to compare the differences in plant performance and disease resistance between different

The European slag contains 15 to 18 percent P 2 O 5 and used as a popular phosphatic fertilizer in central Europe. But slag from Indian steel mills is poor in P 2 O 5 and is not used as a fertilizer. The European slag is suitable for acid soils as it is alkaline in reaction. For effective use, it must be pulverized before application. (iv)
