The search for higher yields, lower production costs, and increased sustainability in agriculture implies optimizing crop nutritional management. In this sense, basalt dust has shown potential to improve soil fertility nutrition. Thus, the goal was evaluate use of a controlled environment. First, an experiment carried out on soils with contrasting textures (sandy medium) under random design, four replications. These were incubated doses 90 days, later analyzed chemical properties. Then, after incubation, experiments pot system, where maize bean plants grown, Plant shoots evaluated dry weight macro- micronutrient accumulations. results incubation test showed that available phosphorus, potassium, calcium, magnesium levels about twenty, ten, fifteen, thirteen times than those without dust, respectively. Maize grown enriched macro accumulations, up five dust. usefulness aiding management agriculture.
