Aggregate stability refers to soil capability to preserve its solid and porous space arrangement when exposed to deterioration process and, it is considered a good indicator of soil sustainability. In Colombia, studies about soil sustainability consider that around 37.2% present conflict of use and its sustainability is at risk. Since through the study of aggregate stability an approximation of the soil sustainability for agricultural use is achieved, a work of research was carried out in coffee lots located in 24 edaphic units. For each unit, three soil samples were taken at a depth between 0 and 20 cm, and their aggregate stability was analyzed by the Yoder method, organic carbon, and texture. In addition, the Stability Structural Index by Pieri (St) was calculated. The aggregate stability values showed that 12 out of 24 soil units such as Tablazo, Guadalupe, and San Agustin do not limit crop production or soil sustainability from the structural part. In 6 soil units such as Doscientos, Catarina, Malabar there is a slight limitation. In six soil units such as San Simón, Campoalegre and Timaná there is a moderate limitation. According to the St, the soils in Doscientos and Timaná are slightly unstable and the other soils are stable. There is a relationship between aggregate stability and organic matter, but not between aggregate stability and St. The use of St is not recommendable to evaluate soil sustainability in the Colombian coffee zone and soil biology indicators must be included.
