The purpose of this study was to evaluate the existence of compacted layers in three different textural classes located in production areas of sugarcane. The study was conducted in production areas of sugarcane at Fazenda Guanabara, located at municipality of New Olympia, Mato Grosso state, Brazil. Data collection was conducted using an impact penetrometer, model IAA/Planalsucar, evaluating the penetration resistance in three different texture (Loam Sandy, Sandy Clay Loam and Clay). Loam Sandy and Clay textures showed the highest penetration resistance. Loam Sandy and Clay textures behaved very similarly in all layers. There were similar values of penetration resistance of the three classes in 0.3-0.4 m layer.
