ABSTRACT
Research was carried out in order to exploit new materials for improving agricultural soil acidity and the effect of slag from steel refinery on some chromic luvisol chemical properties. In Romania annually are produced from 0.18 to 0.2 million tones ladle slag (LF slag) from steel refinery, classified as a dangerous waste due to its alkalinity. It contains high percents of calcium oxide and from this reason we think to be appropriate to be used instead of lime in treatment of acid soils. For improving the reaction of chromic luvisol from the experimental field located at Moara Domnească a metallurgical waste from the Galați steel refinery was used as amendment. The experimental field consisted of five variants, in three replicates V1 (control), V2 (1 t/ha), V3 (2 t/ha), V4 (3 t/ha) and V5 (5 t/ha). The biological material used was maize hybrid LG 30.489.

Keywords: slag, soil acidity, amendment
