Abstract Current Latin American tropical agriculture is not sustainable. Instead of bonding man to the land, it is bringing unemployment and rural exit. Furthermore, a land management model has been developed with technology that has been transferred from countries with temperate soils without taking into account basic climatic, mineralogical, geochemical, ecological and cultural differences, which are present in our tropical ecosystem. One such technology has been the indiscriminate use of highly soluble NPK fertilizers. Under deep leached conditions, this strategy does not bring nutrient conservation.
