Pérdida de nutrimentos por la quema de la vegetación en una sabana de Trachypogon

The losses of nutrients by fire were assesed in a Trachypogon savanna 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 transferred to the atmosphere. Ash deposition returned between 21-34% of Mg, Ca, K and Pand 0.2% of N. Previous data...
