Abstract: Nonlinear mixed model applied in longitudinal data analysis in a soil located in Paragominas, PAThis paper has as an objective to apply the theory of mixed models to the content of nitrogen and carbon in the soil at various depths.Due to the large amount of organic material in the soil, the content of nitrogen and carbon present high variability in the depths of soil surface, and present a nonlinear behavior.Thus, it was necessary to use the approach of nonlinear mixed models to longitudinal data analysis.The use of this approach provides a model that allows to model nonlinear data with heterogeneity of variances by providing a curve for each sample.
