| description | Biomass modeling in forest plantations is an alternative to quantify carbon stored in vegetation. Predictions are important for management decisions or efforts to mitigate climate change. An important relationship is that of soil moisture (q) with biomass. The 3-PG model was used to predict biomass production in different scenarios of q in a Eucalyptus globulus plantation in subtropical climate. From 2007 to 2009, we measured q in the 0 m - 1.8 m soil profile, leaf area index and the diameter at breast height. Precipitation was registered and crop and potential evapotranspiration were estimated for one year based on the water balance, with values of 959 mm, 514.3 mm and 1303 mm, respectively. The predictions of leaf area index and evapotranspiration overestimate observed data. At eight years, biomass was modeled as 165.5 Mg ha-1, of which 23.1 Mg ha-1 is stored in roots and 59.5 Mg ha-1 in aboveground biomass. In conclusion, minimum soil moisture data are necessary to model diameter at breast height and it is desirable to assemble models instead of selecting a single model or using the average of them. |

La modelación de la biomasa en plantaciones forestales es una alternativa para cuantificar el carbono almacenado en la vegetación. Las predicciones son importantes para las decisiones productivas o para los esfuerzos de mitigación de cambio climático. Un aspecto importante es la relación de la humedad de suelo (q) con la biomasa. Se usó el modelo 3-PG para determinar la producción de biomasa en distintos escenarios de q en una plantación de Eucalyptus globulus en un clima subtropical. De 2007 a 2009 se midió q en el perfil 0 m -1.8 m, índice de área foliar y diámetro a la altura del pecho. Se midió la precipitación y se estimaron la evapotranspiración de cultivo y potencial para un año con base en el balance hídrico, con valores de 959 mm, 514.3 mm y 1303 mm respectivamente. La biomasa modelada no fue afectada por q al inicio del año, pero sí por la q mínima del suelo. Los modelos para el índice de área foliar y la evapotranspiración sobreestimaron los datos observados. La biomasa a los ocho años se estimó en 165.5 Mg ha-1, de la cual, 23.1 Mg ha-1 se almacena en raíces y 59.5 Mg ha-1 en biomasa aérea. Concluyendo, los datos de la humedad mínima del suelo son necesarios para modelar el diámetro a la altura del pecho y es preferible el ensamble de modelos en comparación con escoger un solo modelo o usar el promedio de ellos.
