Abstract
With the cooperation of Unipalma S.A. and funding by the Oil Palm Development Fund, Cenipalma has been researching different appropriate ways to manage biomass, by studying the rates of nutrient decomposition and release. To this end, Cenipalma assessed the agronomic potential of biochar from oil palm trunks undergoing renovation at the Unipalma S.A. plantation (Colombian Eastern oil palm-growing zone). In a first stage, researchers determined the amount of biomass from trunks present in one hectare, characterized the material and quantified the nutrient reserves. In the second stage, the biochar produced from the trunks was characterized physically and chemically, nutrient reserves were quantified and the level of nutrients in the soil was assessed. This article presents the research results. Con la cooperación de Unipalma S.A. y la financiación del Fondo de Fomento Palmero, Cenipalma ha venido investigando diferentes formas apropiadas para el manejo de la biomasa, mediante el estudio de las tasas de descomposición y liberación de nutrientes. Por ello evaluó el potencial agronómico del biocarbón obtenido a partir de estípites de palma de aceite en fase de renovación, en la plantación Unipalma S.A. (Zona Oriental palmera colombiana). En una primera etapa los investigadores determinaron la cantidad de biomasa de estípites presente en una hectárea en fase de renovación, caracterizaron el material y cuantificaron la reserva de nutrientes. En la segunda etapa se generó el biocarbón a partir de los estípites, se caracterizó física y químicamente, se cuantificó la reserva de nutrientes y se evaluaron las dosis crecientes de aquel en el suelo. En este artículo se da cuenta de los resultados de la investigación.
