Nowadays, the residues produced by the industry do not have the right destination, consequently, they end up polluting rivers and the environment. Thus, the objective of this work was to evaluate the effect of applying solid residue of charcoal in sandy soil. Vegetable ash has the ability to improve soil quality, so they can be used as a basic fertilizer, increasing the microbial fauna, which is important in nitrogen fixation and organic matter decomposition. Carrot is an excellent vegetable that can exemplify the physical effects of charcoal on the soil, as it is a demanding vegetable, it reacts better in sandy soil rich in organic matter. The production of charcoal when properly conducted is a sustainable economic practice. The experiment was carried out in a greenhouse, in the city of Cornélio Procópio PR, from April 2021 to July 2021, where different doses of ash, repetitions 0; 7; 14; 21; 28 and 35 g dm ⁻³, arranged in 6 treatments and 7 repetitions, so that evaluation was obtained by calculating the dry and fresh matter of the roots and aerial parts of the plants and root length at the end of the trial period. According to this work, carrots corresponded to a significant improvement with ash fertilization, so that doses up to 21 g.dm-3 promoted increases in the evaluated characteristics, and after that caused plant toxicity. It is important that the producer, when fertilizing with ash, pays attention not only to the amount of ash applied, but also to the chemical composition of this organic fertilize.
