EFFECT OF STEEL SLAG LF APPLICATION ON SOIL CHEMICAL PROPERTIES

Liming an acid soil to correct the soil acidity can influence the buffering capacity of the soil. The paper presents the effects of steel slag LF produced in the steel-making process in a Romanian steel refinery on the agricultural utilization. The treatment (an experiment with 5 doses: 0%; 0.1%; 0.2%; 0.3%; 0.4%; 0.5%) has been applied to test and to observe changes in soil pH and some other chemical properties. The pH value increased for all doses and the Cation Exchange Properties have been favorable influenced. An increasing tendency of the soluble salts content was observed under the treatment but the concentrations remained in a normal level.
