Abstract:
Steel slag is a by-product in the process of refining iron by Blast Furnace (BF) or Electric Arc
Furnace (EAF). This by-product can be used for various fields such as construction, industry and
agriculture. This study aimed to observe the use of steel slag in agriculture as fertilizer, lime and
ameliorant in the soils. The method used was the experimental design used steel slag in several
level: 1,2,3,4,5,6,7,8 to 9% to change several soils characteristics of Ultisols and Andisols. The
result showed that steel slag increased pH, decreased P=fixation and P-retention and increased
available P ini Ultisols and Andisols. This result of this research is expected contributed to
government who would like to improve characteristics in sub optimal soils. The novelty is the
using of steel slag in agriculture that not been used widely yet. |
