Abstract

Faltacaria moluccana at its early plantation, is devastated by heat and water stress due to current global climate change. Production forests in Indonesia suggested to use biochar to enhance the durability of early growth F. moluccana in the field. Empty fruit bunches (EFB), a gigantic abundant waste material in Indonesia, pose its potential as biochar feedstock. This study aims to evaluate the effects of EFB biochar on the growth of F. moluccana for one year in a field setting. The experiment used two biochar application rates (25 and 50 tons/ha) and biochar produced at two pyrolysis temperatures (400°C and 600°C). Climatic factors (rainfall and average temperature) were monitored to assess how biochar interacted with field conditions to influence the growth of F. moluccana. EFB biochar increased height and diameter increment by up to 25% and 42%, respectively, compared to control after one year. While pyrolysis temperatures show no impact on growth, biochar application rates of 25 and 50 tons/ha significantly boost diameter increments by 36% and 42%, respectively, compared to controls, without affecting height. Biochar also improves monthly growth increments under water and heat stress. EFB biochar optimizes growth under current climate conditions in Indonesia and mitigates the negative effects of extreme temperature fluctuations.

Abstract

This study explores the effects of pyrolysis temperature of shorea wood biochar and its doses on the soil properties and biomass of Falcataria moluccana seedlings. The focus is optimizing pyrolysis temperatures (400°C and 600°C) and biochar doses (0%, 25%, and 50%) to enhance soil fertility and seedling biomass. Both pyrolysis temperature and biochar dose are critical factors that influence the soil properties, directly affecting its effectiveness as a soil amendment. The research was conducted as a controlled greenhouse experiment over 120 days; each treatment was replicated 15 times. We observed several soil chemical properties, including pH, cation exchange capacity (CEC), organic carbon (C-organic), total nitrogen (N-total), and total phosphorus (P-total). The growth parameters assessed included above ground biomass (AGB), below ground biomass (BGB), total biomass (TB), and root to shoot ratio (R:S). Data analysis involved one-way and two-way ANOVA. Results indicated that soil properties, particularly cation exchange capacity (CEC) and organic carbon content, were improved, thereby enhancing soil fertility. However, ANOVA indicated no statistically significant differences across treatments. Biochar significantly enhanced above-ground and below-ground biomass (AGB and BGB). Nevertheless, both pyrolysis temperature and biochar dose independently influenced biomass accumulation in F. moluccana seedlings. The highest increases were observed in the treatment with the highest pyrolysis temperature (600ᵒC) and the highest dose (50%), which led to an 85% increase in AGB and a 60% increase in BGB compared to the control. Based on the study, Shorea wood biochar, particularly when used at 600°C and 50% dose, significantly improves soil fertility and seedling growth, providing a promising approach for developing F. moluccana plantations.

Abstract

The global demand for landscape trees has been amplified with the increasing anthropogenic activity. South Korea has also witnessed a surge in demand for landscape plants, among others, Juniperus scopulorum gaining popularity for its ecological, economic, adaptability, and management attributes. However, the optimum management practice for high-quality Juniperus seedling production in South Korea remains unknown. This research was conducted on the one-to-two-years-old two cultivars of J. scopulorum, namely Blue Angel and Blue Heaven seedlings, to investigate the combined impacts of varying fertilizer concentrations (0 ppm, 150 ppm, 300 ppm) and biochar content (0% and 20%) under contrasting shading intensities (0%, 35%, 55%) and irrigation levels (200 ml, 400 ml, 800 ml). The study revealed that biochar and fertilizer amendment significantly (p < 0.01 and p < 0.05) enhanced the height and root collar diameter growth in Blue Angel and Blue Heaven in light shade intensity (0–35%) and higher irrigation (400–800 ml) conditions. Similarly, seedlings planted in 20% biochar and 300 ppm fertilizer yielded higher foliar, stem, and root biomass in low shade and higher irrigation conditions. The amount of shade and irrigation and their interactions significantly affected the morphological growth of seedlings for both cultivars, causing positive interaction with soil amendment (biochar and fertilizer application). These findings suggest that efficient seedling production of J. scopulorum management should focus primarily on light shading and moderate irrigation under biochar and higher fertilizer application. The research contributes valuable insights toward optimizing management practices and reducing costs associated with J. scopulorum seedling production in the region.
