Classificação pedológica e análise ambiental da Floresta Nacional de Palmares, Altos-PI

Abstract

The study of soils is essential for the maintenance of biodiversity, which is why pedology is the science of soil morphology and classification and helps us to understand how the interactions between the factors and processes of soil formation occur and how this influences soil attributes, soils perform various environmental services, the study of soil quality is fundamental to knowing the productivity of a forest, the importance of the soil-landscape relationship makes it possible to understand the attributes of the relief and the types of soils that occur in the landscape, enabling the process of detailed study of soils, the landscape is formed by the features of the earth's surface and its components located in the subsurface, where the soil is considered a complex natural body, which transforms over time. This work aims to carry out a pedological classification of the Palmares National Forest located in the municipality of Altos-PI, to classify the level of vulnerability of each soil based on its class and to assess the degree of conservation of the UC based on the soil environmental quality indicator, the soils identified in the Palmares FLONA correspond to Argissolo Vermelho-Amarelo, Latossolo Vermelho, Neossolo Litólico and Plintossolo Pétrico. The fertility results show that these are soils that undergo the intense weathering process typical of tropical environments and that it is essential to maintain the standing forest to conserve carbon in these environments and guarantee the continued availability of nutrients in the soil.
