Reduction of potatos due to hydric soil erosion using space technology Original Research Article

The potatoʹs crop is in the fourth ranking of economic importance in the agricultural Gross Income of Tucuman. The geographical location of its production area makes essential the handling of the hydric soil erosion problems. The purpose of this work is to improve potato crop irrigation management using space information combined with farm practice. The field measurements were carried out using Wide Area Differential Global Position Systems FUGRO OMNISTAR, total station, and double frequency Global Position Systems. The crop irrigation was pursued through scheduling irrigationʹs software whose input comes from satellites of the Matutinal Constellation (LandSat 7, SACC and TERRA). The preliminary results allowed reprograming the irrigation practices for the new cropʹs campaign in order to decrease hydric soil erosion.
