Abstract

The influence of the forest component in the crop-livestock-forest integration system depends on several factors, among which are the plant species used and the row spacing established in system deployment. Therefore, the objective of this study was to characterize the tree component dendrometrically using Eucalyptus grandis x urograndis individuals from the CLFI system and to determine the model fit with volumetric models of homogeneous stands. The study area consists of a six year old CLFI system of Eucalyptus grandis x urophylla, located at the municipality of Cachoeira Dourada – GO. Forest inventory and volume measurement were carried out through the Smalian method. The hypsometric relations of Eucalyptus urograndis were adjusted to seven volumetric models. The arrangement proposed in the crop-livestock-forest integration system (CLFI) was efficient. The models tested (Näslund, Ogaya, Schumacher & Hall, Spurr logarithmic, Honner, Takata and Husch) showed adjustments above 87%, where the models Näslund (99.53%) and Ogaya (99.17%) had the best fit.
