This work intends to use the models to establish global and interactive indexes: global because they include all variables of interest: soil properties, environmental variables, crop characteristics, and management indicators that influence the production; interactive because when an input variable is modified in the model, the rest automatically is also altered. Two indexes that express the yield and risk of production are proposed to better evaluate the soils: the poprodin and the degradin. Poprodin (potential production index): it indicates how much a soil can produce regarding to the potential given by the climate and crop.
