摘要

The basic slag can consist in an alternative source of Ca and Mg, as well as punishment of soil acidity improving the nutricional state of passion plants, and determining the success of the implantation of an orchard. Thus, it was objectified to evaluate the effect of siderurgy slag iron-chromium, in the alterations of the chemical attributes of the soil, in the nutrition of the plants and the development of passion seedlings. For this, it was installed an experiment in conditions of greenhouse, using the following increasing doses of the residue: zero; half; once; once and half and twice to raise V =80%. After 30 days of incubation of the slag in the soil, it was proceeded the plantation of the passion seedlings, in substratum of a distrofic, acid Red Latossol (pot with 2,8 dm3), cultivating them per 85 days. The application of the siderurgy slag iron-chromium promoted the neutralization of the acidity of the soil, however, in doses relatively low (360 kg ha-1) resulted in reduction in the nutrients and the production of dry matter of passion seedlings.
