description	The amount of leaf litter produced by avocado trees cv. Hass is an important potential source of mineral resources, and quantifying its production and nature is crucial to understanding the cycling of nutrients. The main objective of this study was to quantify the production of leaf litter and fallen flowers and small fruits in avocado orchards at eight locations in three producing areas in the Department of Antioquia (west, southwest, and north). The highest leaf litter production occurred in southwest Antioquia, at Jardin (7.6 t ha-1 year-1); the east locations had similar leaf fall (4.03-3.4 t ha-1 year-1). The dry matter produced in the north was very similar in both locations. The dry matter was 2.8 t ha-1 year-1. Higher leaf litter was recorded in all locations during the driest periods. Approximately 80% of the fallen fruits had diameters less than 1 cm. The highest flower production and fall occurred in southwest Antioquia, followed by the northern region.

La cantidad de hojarasca producida por árboles de aguacate cv. Hass constituyen una importante fuente potencial de recursos minerales, por lo que la cuantificación de su producción y naturaleza son cruciales para comprender el ciclaje de nutrientes. El objetivo principal de este estudio fue cuantificar la producción de hojarasca, flores y frutos pequeños caídos, en huertos de aguacate, en ocho localidades y en tres zonas productoras del departamento de Antioquia (Oriente, Suroeste y Norte). La mayor producción de hojarasca se presentó en el Suroeste antioqueño, siendo superior en Jardín (7,6 t ha-1 año-1); las localidades del oriente presentaron caída de hojas similares (4,03- 3,4 t ha-1 año-1). La materia seca producida en el norte fue muy similar en ambas localidades. La materia seca obtenida fue de 2,8 t ha-1 año-1 Los mayores aportes de hojarasca en todas las localidades se presentaron durante las épocas más secas. Se encontró que aproximadamente el 80% de los frutos caídos corresponden a diámetros menores a 1 cm. Las mayores producciones y caída de flores se presentaron en las localidades del suroeste Antioqueño, seguido de la región del norte.
