espagnol; castillan. At present there are two systems of vegetable production in the Bogota Plateau, the conventional production systems (CPS) and the organic production systems (OPS). Soil samples were collected from both production systems. Each soil sample was performed and analyses of fertility based on data mining of nutrients were diagnosed with various aspects of the fertility of the soil chemistry. These were compared them with the standards of fertility and to supply tools to increase the productivity organic production system. The two systems of vegetables productions present pH adapted that fluctuant between 5.5 and 6.6. In the OPS presented deficient contents of phosphorus in the 92% of the soil samples, objected to CPS where it prevailed the deficiency in 73% of the soil samples. In the OPS presented deficient contents of sulphur in the 81% of the soil samples, contrasted with the 19% of CPS. The two systems of vegetables productions present deficient contents of manganese, reflecting the low contribution of this element in the plan nutrition, since the zone is deficient the contents natural.
