The basic slag can consist in alternative source of Ca and Mg, as well as conecting soil acidity improving the nutricional state of guava plants, and determining the success of the implantation of an orchard. The present work was carried out to evaluate the basic slag in chemical attributes in soil in the nutrition of plants and the production of guava plants. By the way, an experiment was conducted in Taquaritinga-SP, in pot conditions, with increasing doses of basic slag: zero; half; once, once and half; twice and twice and half to raise V =70%. After 90 days of the incubation of the basic slag in soil, the plantation was proceeded in vegetative propagation, in Ultisol (pot with 2.8 dm3), cultivating them per 105 days. The basic slag application positively affected values of pH, SB and V%, and the concentrations of Ca, Mg and P and H+Al in the soil. The guava plants had significant by increased the height, number of leaves and the foliar area, the concentration of Ca, Mg and P of the aerial part and the root of the plants and, consequently, the dry matter of the aerial part and the root. Therefore the basic slag revealed viable in the production of young guava plants as corrective of acidity of soil and source of nutrients (Ca e Mg).
