Biochar can be defined as vegetable biomass, which has undergone pyrolysis in a low oxygen environment. It can contribute to chemical, physical and biological improvements in the soil. Different biomasses can be used in the production of biochar. However, characterization studies are needed before its recommendation. The aim of this work was to test the temperatures: 300, 400 and 500 °C in Theobroma grandiflorum for biochar production and to characterize the samples, submitted to different temperatures, to verify which temperature presents the best chemical and physical properties. The increase in temperature to 500 °C promoted an increase in carbon, nitrogen, nutrients, as well as pH and electric conductivity. There was a reduction in the original mass and in the values of polyphenols, celulose, density and the aromaticity index.
