“…Silvicultural management was minimum; the soil was subsoil and then calcium was applied to regulate the pH to 6.2, then fertilization was applied and sowing of trees that died in the first month after the plantation was established. This minimal management is due to cost reduction since the goal is biomass, which is standard for this plantation in Costa Rica (Arias-Aguilar et al 2018).…”

“…As a result, it is estimated that world energy consumption will increase by 4% between 2020 and 2030, making it necessary to exploit and optimize new energy sources (Arias et al, 2020). Nowadays, 78% of the world's energy comes from non-renewable sources (natural gas, coal and fossil fuels), while 22% comes from renewable sources such as hydro, solar, wind and biomass (Arias-Aguilar et al, 2018).…”

“…HDEP has been implemented in a limited way in the tropical region due to the high waste generation by agricultural and forestry industries (Valverde et al, 2020). However, current trends are focused on waste valorization and the generation of new by-products, which results in less available waste (Arias-Aguilar et al, 2018). This aspect has stimulated the development of energy plantations with planting densities of more than 5000 trees ha -1 (Bouillet et al, 2003).…”

“…The species that show the best development under the HDEP model include Eucalyptus tereticornis (Arias-Aguilar et al 2018), which has been used in the highlands of Costa Rica under three planting densities: 1,000, 5,000, and 20,000 trees ha-1 (Navarro-Camacho et al, 2014). Using this as a reference, studies have determined the capacity to generate between 36.10 and 107.67 ton ha-1 of dry biomass (stem and branches) in four-year cycles, obtaining variations in biomass prodction as a function of planting density (Navarro-Camacho et al, 2014;Arias et al, 2020).…”

Background: The use of tree plantations for energy purposes has shown an increase in their use in tropical regions due to the species' rapid growth and low cost of energy generation. This has led to the development of optimization studies of crop conditions.However, the determination of the effect of spacing on physical, chemical and energy properties has not been precise for Eucalyptus tereticornis, which limits the development of plantations with optimal silvicultural conditions. Results:The study analyzed the growth and chemical, physical and energetic properties in a four-yearold plantation. The results showed that mortality ranged from 29 to 69%, being the 1.0 x 2.0 m spacing the one that presented better yields with a significantly higher diameter and height (9.13 cm and 14.17 m, respectively) with a higher biomass accumulation (140.04 ton ha -1 without treetop) concentrated mainly in the stem. The other two spacings presented statistically lower and non-significant values. The physical properties were obtained densities of 0.57 to 0.66 g cm -3 , with a specific density of 0.58 and moisture content of 57.7%. The chemical properties only showed differences in carbon concentration (50.11 to 69.16%). The energetic properties showed a caloric power between 4780 to 6059 kcal kg -1 , with a variation in volatile content of 10.9% and 1.6% in ash. Conclusion:The planting spacing generates a gradient in the production, mortality and property of the biomass, being the spacing of 1.0 x 2.0 m being optimum for establishing the study species for Costa Rica.

THE DRYING PERFORMANCE AND POST-DRYING QUALITIES OF Eucalyptus saligna EXPOSED TO INTERMITTENT AND CONTINUOUS DRYING. Eucalyptus saligna tends to develop defects during its drying process, thus limiting its use as construction or furniture material. Intermittent drying, which applies non-heating phases between heating phases, has the potential to overcome this issue. This study evaluated the effects of 3 intermittent and one continuous schedule on the species' drying performance and post-drying qualities. The results showed that the boards from all intermittent schedules exhibit significantly slower drying rates (from-9.4x10-3 %/hour to-1.57 x10-2 %/hour) than those from the continuous schedule (from-5.12 x10-2 /hour to-1.03 x10-2 %/hour). All intermittent schedules tended to decrease the collapse depth in E. saligna boards (the average value range of the three schedules was 1.162-2.032 mm) than the continuous schedule did (the average value was 5.12 mm). Nevertheless, applying higher temperature than that used in the continuous schedule, during the heating phase of the intermittent schedule, potentially increased the moisture gradient, residual drying stress, end check length, internal check percentage, and spring depth.
