The objective of this research was to study the biochar as an amendment, in disturbed soils in the department of Cesar. To do this, the biochar of cuesco was obtained with a Thermo Gravimetric Analysis or TGA equipment; a characterization of the biochar obtained was made, based on the NTC 5167 on the characterization of solid amendments; the characterization of the soil according to each parameter; pH: potentiometer method according to NTC 5264, CE: conductivity according to USDA, CIC: method of ammonium acetate according to the ciat, Actual density: pyramometer method according to Jaramillo, Humidity retention: by the method proposed by Mataix, Phosphorus: Olsen method modified and CO: by Walkley-Black method; and as a bioindicator cowpea, castilla, Chilean or blackhead plant was used; whose scientific name is Vigna unguiculata L. Walp of the order of legumes determining number of plants by count, measurement of plant with metric tape, weight with balance, length of stem, length of root and number of bifurcations. The soil showed an improvement in some of its properties such as the CIC and the real density. As well as on the weight and growth of the plants used in the trial.
