Abstract
The root distribution patterns of oil palm were studied in relation with the soil physical and chemical characteristics. The work took place at the Guaicaramo S.A. state, municipality of Barranca de Upía, department of Meta, Colombia. Root density sampling was performed with the trench method in the traffic and non-traffic ways in five healthy randomly selected palms. Pair correlations were performed between root density and individual physical-chemical parameters for the top 20 cm of soil. Positive correlations were obtained between root density and K and P concentrations, and negative ones were obtained for exchangeable Al and bulk density. The results indicate that there is a significant effect of soil conditions on root growth which needs to be taken into account for future research and for improving the agronomic management of the crop Se estudiaron los patrones de distribución del sistema radical de la palma de aceite en función de las características físicas y químicas del suelo. El trabajo se realizó en la plantación Guaicaramo S.A., ubicada en el municipio de Barranca de Upía, departamento del Meta (Colombia). El muestreo de densidad radical se efectuó con el método de perfiles lavados en calle de cosecha y en la calle sin tráfico, en cinco palmas sanas seleccionadas en forma aleatoria. Al correlacionar pares de datos de densidad radical y la concentración de cada parámetro físico y químico en los primeros 20 cm del suelo, se establecieron correlaciones positivas entre la densidad radical y las concentraciones de K y P, y correlaciones negativas para el aluminio intercambiable y la densidad aparente del suelo. Los resultados indican un efecto notorio de las condiciones del suelo en el crecimiento de la raíz, lo cual debe tenerse en cuenta en futuras investigaciones y en el manejo agronómico del cultivo.
