Impact of Ground-Based Logging Machine on Soil Physical Properties and Tree Growth

Five experiments were conducted to determine the impacts of ground-based logging machines on soil physical properties and on early gr01vth of Acacia mangium Willd. The experiments are : (i) a survey of the areal extent of logging machine disturbance, (ii) effects of logging machines on soil phys...
