Conteúdo: 	The aim of this study was to evaluate the effects of a zeolite and urea mixture on ammonia volatilization. Two experiments were carried out: a greenhouse pot experiment and a field trial with Tanzania grass pasture. The pot experiment used five zeolite ratios (0, 12.5, 25, 50, and 100 percent relative to the N-urea level used) mixed with 100 kg ha?1 of nitrogen (N). The field trial used four treatments: 0, 12.5, 25, and 50 percent of zeolite, at the dose of 50 kg ha?1. In the greenhouse experiment, the smallest losses by volatilization occurred at the proportions of 25 percent and 100 percent. During the summer, the mixture of 25 percent of zeolite in N-urea led to a reduction in ammonia volatilization from 33.5 to 7.6 kg ha?1. However, in the winter, volatilization was very low, and there were no differences between the treatments. The addition of 25 percent of zeolite in urea was the most appropriate relation.
