Resumo
The savannas reached prominence in the development of corn (Zea mays L.), soybean
(Glycine max L.) and processing tomato (Lycopersicum esculentum Mill.), Depending on the
economic and social importance of these crops. The problems of acid soils and nutrient deficiency
in the savannas are common in most soils, but once overcome these obstacles, the cultures exhibit
satisfactory development and production. Increasingly it becomes necessary, by the dynamism that
modern agriculture provides that alternative mechanisms of replenishment of nutrients to the soil
are offered, due to the high cost of fertilizer and high extraction of these elements in each cycle of
crops. The use of industrial waste from various sources has shown potential for agricultural use, for
purposes of correction of acidosis, addition of macro and micronutrients to the soil or even
physical conditioning of the soil, always under careful criteria used to avoiding the environmental
contamination. The aim of this study was to evaluate the effect of the electric arc furnace dust
coming from the steel industry as a source of micronutrients in crops of corn, soybean and tomato
at different levels of liming. The tests were conducted in two locations. A field experiment was
conducted at the experimental farm of the School of Agronomy and Food Engineering,
Universidade Federal de Goiás, Campus Samambaia, in Goiânia-GO, Brazil and other, in a
greenhouse at Palmital Farm, municipality of Urutaí-GO, in campus of the Instituto Federal
Goiano. During three years, were evaluated in Goiânia-GO, the use of steelmaking dust in corn in
rotation with soybean and, in Urutaí-GO, for seven months, the tomato crop in succession with
soybeans. The results in both experiments indicated that the levels of heavy metals detected in soil
and leaves of the plants analyzed were below the limits considered toxic.
