“…EFB addition to the soil Soil organic carbon was significantly different between the treatments (F 3,92 = 2.9, P < 0.05). b Annual fresh fruit bunch weight as a function of soil organic carbon, with a time lag of 2 years (F 1,78 = 8.4, P < 0.05, R 2 = 0.11) may increase soil organic carbon by decomposition and improved nutrient recovery (Baharuddin et al 2009;Thambirajah et al 1995). Increases in soil organic matter are associated with increased porosity, aggregate stability, hydraulic conductivity, and biological activities, which facilitate nutrient cycling and crop production (Edmeades 2003;Magdoff and Weil 2004).…”

Crop residue management is an important agricultural practice that has a high potential to improve soil health and optimize crop production. Compared to annual crops, relatively little is known about crop residue management effects on the yield and temporal stability of perennial crop production. This study focused on oil palm (Elaeis guineensis), an important tropical crop that had expanded rapidly over the past decades. We aimed to understand the effects of applying a major oil palm residue, the empty fruit bunch, on crop yield and temporal stability of production. We compared 15 years of crop yield performance from a field trial in Sumatra, Indonesia. The treatments included empty fruit bunch application of three application rates (30, 60, and 90 t ha −1 year −1), and a reference treatment of chemical fertilizers with no addition of empty fruit bunch. Compared to the reference treatment, the cumulative crop yield over 15 years under low, medium, and high application rates of empty fruit bunch increased by 2.4, 5.9, and 4.8%, respectively. The annual crop yield and temporal stability in production were not significantly different between treatments. Soil organic carbon was significantly higher under medium application rate of empty fruit bunch compared to that under the chemical fertilizer treatment. Soil organic carbon and relative humidity were positively associated with annual crop yield with a time lag of 2 years. This study is the first to show that both crop yield and temporal variability of oil palm production can be maintained under crop residue application, compared to chemical fertilizer treatment. Furthermore, climatic conditions had strong effects on the temporal variability of oil palm production. These findings will inform the design of optimal empty fruit bunch application schemes that enhance sustainable intensification of oil palm cultivation.

“…Although the demand of plywood is increased, it also suffers due to the shrinkage of wood sources and consequently increment of logs price [2]. The logs production volume decreased to 4.4 million m 3 from 6.5 million m 3 in year of 2005. This was due to the heavy logging activity which damaged the potential tree for future source.…”

“…Oil palm (Elaeisguineensis Jacq) is a non-wood material and are the most abundant crops planted which can be obtained at any plantation around Malaysia. Based from statistical data of Malaysian Palm Oil Board, there are 5.39 million ha of land are being planted with this agriculture in 2014 [3], [4]. The oil palm stems (OPS), oil palm fronds (OPF) and oil palm empty fruit bunches (EFB) is the residues that are left behind after cutting process as the tree reach 25 to 30 years age [5].…”

Plywood is a wood product frequently utilized in building as part of concrete formwork systems. In the concreting process, plywood formwork needs to be strongly made to withstand the pressure subjected by the wet concrete as well as the impact. To reduce the dependency on solid timber as plywood, oil palm stem offers alternative materials. There are four main weaknesses of oil palm stem (OPS) as a material for plywood manufacturing; high variations in density and moisture content (MC), high water absorption and high surface roughness. Therefore, this study modified the drying and treatment process of OPS veneer. The veneer was predried by using roller presser for removing a large amount of water and later treated with medium molecular weight phenolformaldehyde (MMwPF) to bond together parenchyma tissue, cell wall, and a lumen for much uniform density and better surface bonding. The Charpy impact of OPS plywood developed in this study denoted as PTA was investigated. These properties were compared with the properties of another two types of commercial OPS plywood denoted as PTB and PTC which were manufactured using OPS veneer with tropical hardwood veneer for face and back veneer and control plywood denoted as PTD which was manufactured using 100% tropical hardwood veneer. The results showed that PTA has the highest mean value of energy and strength for both notched and unnotched Charpy impact.
