ABSTRACT: Environmental problems have shown the need to innovate with new alternatives for agricultural production. Methods that do not negatively influence the environment, for which the use of bio-inputs for agricultural production is gaining strength in agricultural production. The use of biochar as a soil improvement input is very recent, as it shows multiple improvements in both physical and chemical characteristics. In the present study, the effect that biochar has on the lamb's lettuce crop was evaluated. Biochar was obtained in an artisanal way, using a small oven, to demonstrate that coal can be obtained in an easier and more feasible way for the producer. For the study, certified canon seed was used, sown in blows, at a density of 10 cm. in an experimental unit of 1 m2, in a total of 16 experimental units, where a random block design model was used. 4 treatments with 4 randomly ordered blocks were investigated. Control treatment (substrate without biochar), treatment 1 (substrate with 2% biochar), treatment 2 (substrate with 4% biochar), treatment 3 (substrate with 6% biochar). With treatment 2, the best results were obtained in the crop as well as in the soil. What is recommended is to apply the biochar calculating 2% of the volume of the arable layer of the soil. It concludes by indicating that the application of biochar to the soil brings multiple benefits for both the crop and the soil. Beingthe latter the most benefited, improvingthe chemical and physical characteristics, it improved its availability of organic carbon, which shows that Biochar fixes carbon to the soil in a more stable way, a very important environmental characteristic
