According to the study, steel-slag-based silica fertilizer significantly increased the dry weight of rice stems and leave and seed yield; This meant that steel …
In addition to selling steelmaking raw material product to steel manufacturers in Japan and Southeast Asia, this product is also sold to glass manufacturers and fertilizer manufacturers. ... Iron and Steel Slag for Road Construction; Steel Slag Hydrated Matrix; Quicklime and Mini Pellets;
Singla and Inubushi also conducted an experiment on steel slag (SS) using two different types of slag fertilizers in paddy soil. The application of SS at a rate of 2 …
Accelerants can effectively enhance the performance of anaerobic digestion (AD) system. The effects of optimized steel slag as accelerant in the AD of cow manure and the fertility utilization of the digestate were investigated. Results show that all steel slags collected from different iron and stee …
Second Set of Experiments. Figure 13a (90% steel slag and 10% commercial fertilizer) and 13 (b) ( steel slag) are shown the growth of peas plant. For 2nd set of experiments, only peas plant was chosen. After conducting 1st set of experiments, it was observed that the growth of chickpea plants is quite slow with …
The steel slag was used to examine the use of steel as an ameliorant. The result infoemed that steel slag can increase and absorbing water, protect plant from hydrophobicity (Winarna, et al, 2016). Another research was conducted in Sanggau Regency, West Kalimantan, showed that steel slag improved the productivity of dry milled rice
The process of refining iron by Blast Furnace (BF) or Electric Arc Furnace (EAF) produces steel and by-product: steel slag. This by-product can be used for various fields such as construction ...
Management practices including augmenting the ratio of organic to chemical fertilizers, implementing deep application techniques and reintegrating straw into fields can bolster food production ...
The feasibility of steel slag used as an iron fertilizer was studied in a pot experiment with corn. Slag alone or acidified slag was added to two Fe-deficient calcareous soils at different rates ...
production of iron and steel slag in Europe in 2008 was of 45.6 million tonnes1 and decreased in 2009 and 2010 only due to the steel production slow down caused by the ... slags are mainly used for road construction, hydraulic engineering, and fertilizer, BF slag is mainly used for cement production 2. 1 Source: European Slag Association, EUROSLAG
To solve the problems of deep nitrogen removal in wastewater treatment plants and the high value utilization of steel slag in the metallurgical industry, this work aims to prepare a sulfur/steel slag …
Steel slag fertilizer was applied at a rate of 200 and 400 g m −2, which led to an increased yield of about 8% for the rice planted compared with the rice planted without the slag fertilizer application; this increase extended another 4% when the applied amount of slag was doubled (Gao et al., 2015). Steel slag, however, contains trace ...
