This work aims to evaluate the behavior of macronutrients and micronutrients in the soil when there is successive application of swine wastewater in growing jatropha (Jatropha curcas L.). The experiment was conducted in Palotina – PR, Brazil. The experimental parcels were designed and built in an area of 900 m2, in a completely randomized design with six treatments and three replications. The doses of swine wastewater (SW) were set in proportions of 0, 40, 80, 120, 160 and 200 m3 ha-1. Soil attributes related to acidity did not suffer influence of successive applications of SW. In the first application none of the parameters evaluated suffered interference of the doses. Macronutrients K and Ca presented quadratic behavior in the second application. There was an increase in micronutrient Cu in function of the dose of SW in the second and third applications. Fe increased only in the third application of SW. Key words: Organic fertilization, macronutrients, micronutrients, mobility in soil.
