Eventual signals of split sypersymmetry in cosmic ray physics areanalyzed in detail. The study focus particularly in the quasi-stablecolorless R-hadrons. coming from the confinement of the long-livegluinos predicted by split SUSY with quarks, anti-quarks and gluons.The main were obtained from a realistic Monte Carlo simulation ofR-hadrons. initiated air showers by means of the AIRES engine. Theseshowers present clear differences with respect to the standardparticles initiated ones and allows one to expect their detection atthe Auger Observatory. If these kind of events are not detected in thenear future, stringent bounds on supersymmetry will be obtained. Thepossible connection between heavy gluinos and Centauro events isspeculated.
