SisILPF_Eucalipto software runs simulations of how eucalyptus plantations in integrated crop-livestock-forest systems will grow and produce, according to the management regimes indicated by the user. Users can use the software to simulate all the options for eucalyptus plantations for each climate and soil condition, forecast wood production in the present and in future conditions, perform economic analyses, and then only implement the best alternative in the stands. The software helps in making decisions about when, how much, and how to thin, and when to carry out the final harvest. The system indicates the growth and production of the trees and makes it possible to simulate various different thinnings, generating a production table by diameter class for each thinning and for the final harvest. In addition, wood volumes are shown by industrial use classes based on the log dimensions indicated by the user. The program also calculates the carbon sequestered by the trees, total wood production, and wood production by industrial use class (such as sawlogs, pulplogs, and energy wood).
