Caracterização física e morfológica dos solos do Parque Estadual Mata da Pimenteira - PE

Abstract

The investigation of the process and pedogenetic factors of the soil in units of conservation allows the establishment of standards that can subsidize in the planning of the environmental activities important for the preservation of its ecosystems. The objective of this work was to identify and unsderstand the pedogenesis of the most representative soils of Mata Pimenteira State Park, semi-arid region of Pernambuco. Seven soil profiles of higher occurrence were described and collected for morphological and physical characterization. Most of the soils were sandy and sometimes crusty except for the Luvisols class. In the northern part of the park were found Iceptsoils, while in the south-southeast portion the Cambisols. The Cambisols showed a great correlation od characteristics with their original material, reflecting in color, texture and consistency. The P3 profile presented greater pedogenic evolution in relacion to the others. In all the Cambisols biogenic structures were found in varied formats, differing in quantity as the depth increases. The use of the soils influences the permanence of these structures, because with revolving they can be destroyed. The Luvisols presented restriction to water infiltration, due to the accumulation of clay in depth, indicating the presence of mottles. Therefore, there is a high correlation between soil characteristics found in the Park and the source material. Cambisols have similar morphological and physical characteristics and the essentially sandy nature of the soils except Luvissolos reflects the higher infiltration rates.
