Technical thinning age of eucalyptus trees grown in crop-forest integration systems
Abstract: The objective of this work was to determine indicator methods that help to establish the first thinning age of trees to be used in crop-livestock-forest integration systems based on the relationships between eucalyptus growth and soybean and corn production. The experiment followed a completely randomized block design, with four replicates and three production systems (crop monoculture, forest planting monoculture, and crop-forest integration). The percentage of entries and Veiga’s methods, as well as the target growth rates, were assessed to set the thinning age to be adopted for integration systems. The percentage of entries method, the age of the maximum mean annual volume increase, or tree age when diameter growth stagnation occurs did not prove adequate as a reference for thinning, when yields of agricultural crops are not jointly monitored. Methods focusing on controlling the basal area and target diameter increase are feasible to define the technical age for thinning implementation and control.
