Beskrivning:The losses of nutrients by fire were assesed in a Trachypogonsavanna located in Calabozo,Venezuela. About 95% of the biomass, 97% of N, 61% of P, 76% of K and 65% of Ca and Mg were transferredto the atmosphere. Ash deposition returned between 21-34% of Mg, Ca, K and Pand 0.2% of N. Previous dataindicated that precipitation and atmospheric fixation (in the case of N) could replace the rest of N, Ca, K and Mgtransferred to the atmosphere. As a consequence of frequent burning (annual or biannual), the soil of the savan-na showed lower organic matter and available Pand K content when it is compared with a 32 year protectedsavanna.
