| description | Retrophyllum rospigliosii (Podocarpaceae) is a native conifer species of high Andean forests that is currently under endangered status. To evaluate if the fertilization of the soil improves the yield of R. rospigliosii stands, a plantation of this species was established in the Colombian Andean zone in 1999 and monitored over time (years: 2003, 2004, 2006, 2008, 2009, 2010, 2016 and 2018). A longitudinal analysis was performed using a linear mixed model to evaluate the effect of fertilization treatments on growth of R. rospigliosii. Average growth rates found in this plantation were slightly higher than those reported for this species, but slower compared to other coniferous species commonly planted in the Colombian Andean zone. The average annual increment in diameter, height, basal area, and volume in the control treatment was 12 mm, 0.661 m, 2.050 m2 ha-1 and 0.012 m3, respectively. The fertilization treatment number 6 (50 kg ha-1 of N, 20 kg ha-1 of P, 2 kg ha-1 of B y 5.5 kg ha-1 of trace elements) showed a significant increase in the growth variables evaluated relative to the control (9.2%, 8.4%, 18.4% and 25.0%, respectively for diameter, height, basal area, and volume) during the study period. This is possibly because early fertilization favors early crown closure and weed reduction, which, added to the adaptations of this species to low soil nutrient availability, maintains the effect over time. |

Retrophyllum rospigliosii es una especie amenazada nativa de los bosques altoandinos. Con el fin de evaluar si la fertilización química incrementa el crecimiento (diámetro, altura, área basal y volumen) de R. rospigliosii, se estableció en 1999 una plantación de esta especie en la zona andina colombiana. A partir del monitoreo de la plantación (años 2003, 2004, 2006, 2008, 2009, 2010, 2016 y 2018), se realizó un análisis longitudinal mediante un modelo lineal mixto para evaluar el efecto de los tratamientos de fertilización en el crecimiento. Las tasas de crecimiento promedio encontradas en esta plantación fueron ligeramente superiores a las anteriormente registradas para esta especie, con un incremento medio anual del diámetro, altura, área basal y volumen para el testigo de 12 mm, 0.661 m, 2.050 m2 ha-1 y 0.012 m3, respectivamente, pero más lentas en comparación con otras especies de coníferas comúnmente plantadas en la zona andina colombiana. El tratamiento de fertilización No. 6 (50 kg ha-1 de N, 20 kg ha-1 de P, 2 kg ha-1 de B y 5.5 kg ha-1 de elementos menores) conllevó un incremento significativo en las variables evaluadas respecto al testigo (9.2%, 8.4%, 18.4% y 25.0%, respectivamente para diámetro, altura, área basal y volumen) durante el período de estudio considerado. Ello posiblemente debido a que la fertilización temprana favorece un pronto cierre de copas y la reducción de malezas, lo cual, sumado a las adaptaciones de la especie a la baja disponibilidad de nutrientes del suelo, mantiene el efecto a lo largo del tiempo.
