Variações microclimáticas e edáficas em sistemas silvipastoris no município de Belterra, Pará

Abstract
The objective of this work was to evaluate microclimatic and edaphic variations in silvopastoral systems, a system in which forest, forage species and animals that graze in consortium are integrated for production. The research was conducted at Fazenda Boa Safra located in the municipality of Belterra. The data were collected in a timely manner in October 2016 in two environments: four forage areas and four arboreal areas with the species: Andiroba (Carapa guianensis Aubl), African Mahogany (Khaya ivorensis A. Chev.), Teak (Tectona grandis L. f.) and Cumaru (Dipteryx odorata Willd.). The variables studied were temperature, soil moisture, litter stock and canopy cover. The results indicate that coumaru is the species that offers better thermal comfort compared to other species, while andiroba stood out in the best litter supply. The role of vegetation cover promoted by trees in the silvopastoral system is highlighted, promoting a better surface temperature of the soil (2 cm deep) in relation to pasture.
