SOIL AND VEGETATION OF THE CAMACUÃ, CAMAPUÃ AND TUCUM PEAKS –CAMPINA GRANDE DO SUL - PR

Abstract

The objective of this work was to characterize, to classify and to observe the relationship between the soil and the vegetation that occur on the Camacuã, Camapuã and Tucum peaks. The original vegetation was classified and the vegetation physiognomy was characterized. Soil profiles were exposed for morphologic description, sampling for chemical and particle size analysis. It was identified three distinct phytogeographical formations, being two arboreal (“Floresta Ombrófila Mista” and “Floresta Ombrófila Densa”) and one herbaceous (“Refúgio Vegetacional”). The physiognomy a of the “Floresta Ombrófila Densa” was altered by the altitude. The height, the diameter of the trees and the tree forest strata number had diminished with the increase of the altitude. Five soil classes were identified (Entisols and Inceptisols), which present small depth, low fertility, high acidity and organic carbon content. There is relation between soil and vegetation, and as the clay content and the soil nutrient availably increase, the high of the tree also increase, been complex the vegetation.
