La Etnoedafología en México una Visión Retrospectiva

Abstract

After, 20 years making studies related with ethnopedology, it has been possible to show that Mexican ethnical groups have an orderly and systematic soil knowledge, that is useful for agricultural and non
agricultural purposes. Moreover, the local soil knowledge can be transformed into a soil map, and it is more precise and accurate than similar technical maps, but with a lower cost. Also, it has been possible
to generalize the local soil maps into regional maps through interpretation of aerial photographs and for the same purpose it was found problems with interpretation automatic images. The experience
generated has shown that ethnopedology studies are also an useful tool of communication between technicians and farmers, that produces a knowledge integration through their mixing, as a physical
phenomenon that is, it is necessary the cooperation more than competition of knowledge’s.
