The soil-plant relation is very important for the comprehension of native and planted forests development, considering that trees interfere in the soil through root system and organic matter deposition, being the soil the responsible for plant nutrients supply, water delay, shelter for fauna, and also the natural substrate for several vegetations. Therefore, this research aimed to study part of nutrients and organic carbon cyclic, at Pinus elliottii Engelm plantation and Atlantic Rain Forest, in Irati, Paraná, Brazil. The area is located in Forest Technician School, with 176,5 ha. The representative soils of both forests were classified as Leptosol and Cambisol. The results obtained with this research demonstrated that carbon concentrations, soil and litter nutrients, vary significantly in both forests: planted forest (Pinus elliottii) and native one (Atlantic Rain Forest). At forest plantation, the carbon contents, as well macro and micronutrients, pointed out values in average lower than the contents found at native forest. The variousness of species and the most ecological complexity of Atlantic Rain Forest may have influenced over the results obtained, in this relationship with Pinus elliottii plantation. The conclusion was that Atlantic Rain Forest showed better conditions of nutrients supply and organic carbon fixing.
