The neutralizing components of steel will residue are linked with high energy, combined with the presence of several metallic elements; these characteristics interfere in the chemical evaluation of their neutralization power. The aim of this study was to evaluate if the neutralization power of lime would be compatible with the residue used to produce steel, as a function of pH, H+Al, and Ca+Mg contents on acid soils in the Cerrado region, for sugar cane cultivation. This study was performed in 20 dm³ pots in a greenhouse, with Acrustox and Quartzipsamment soils, in two sucessive cultivations of sugar cane (first cutting and second cutting), harvest was 210 days after ammendments incorporation, for each cultivation. Treatments constituted of two corrective agents: limestone and steel will residue, in two levels of application, as follows: level 1 = the rate to increase V to 50%, and level 2 = double of the rate necessary to increase V to 50%. At the end of each cultivation, soils were sampled and analysed chemicaly. The reactivity of the steel will residue depends on the soil class type. The efficiency of the steel will residue based on the power of neutralization adopted for limestone was not sufficient to allow evaluation of the quantity necessary of the product for the correction of soil acidity, suggesting the necessity of further studies.
