“…It is pertinent to investigate optimum water supply that has been identified as a major cost of oil palm production (Fereres & Soriano, 2007). According to Safitri et al (2019), the various negative issues associated with the absorption of water by oil palm plants are inversely proportional because water uptake through the roots of the oil palm is relatively low compared to wheat, rice, maize, soybean, and barley. The maximum level of water absorbed in the upper root zone also shows that oil palm plants absorb a lot of rainwater, which is fast circulation compared to groundwater.…”

Crop water use efficiency is critical for high yields in conditions of limited water supplies. This study aims at determining the effect of application bio-silicic acid (BioSilAc) on water use efficiency and nutrient availability for immature (2 years after planting) and mature (5 years after planting) oil palms in sandy soil during a period of low rainfall. A field experiment was conducted on sandy soil at an oil palm plantation in Central Kalimantan. The experiment was arranged in a randomized block design with seven treatments and three replicates using a combination of composted empty fruit bunches of oil palm (CEFBOP) and BioSilAc applications. The treatments (tree-1 year-1) were as follows (tree-1 year-1): (T1) 100% NPK standard dosage; (T2) T1 + 1.5 kg quartz sand; (T3) 75% (T1) + 1.5 kg quartz sand; (T4) T1+ 4 tablets BioSilAc; (T5) 75% (T1) + 4 tablets BioSilAc; (T6) T1 + 50 kg CEFBOP + 2 tablets BioSilAc; and (T7) 75% (T1) + 50 kg CEFBOP + 2 tablets BioSilAc. The parameters observed were soil and leaf nutrient contents, average weight, and number of fresh fruit bunch (FFB), and daily water usage and water potential using a sap flow meter and stem psychrometer to calculate water use efficiency in T1 (control) and T5 which represents the application of BioSilAc. The results indicated that the application of 75-100% NPK + 4 tablets BioSilAc tree-1 year-1 in mature oil palm was capable of improving yield of11.9% (T5) and 12.1% (T4) and water use efficiency of 31.3% (mature) and 50.4% (immature) of the control treatment.

The varying condition of climate, soil properties, crop stage, ground water existing in oil palm cultivation require the specific water balance model to perform the precision crop water use. The purposes for this research were to develop oil palm water balance model for calculating the hydrological parameter of oil palm and analysing oil palm water footprint and root water uptake distribution in root zone. The model of oil palm water balance was developed through the following step: oil palm root architecture study, instrument installation and data observation, model development and calibration. The oil palm water balance tool was developed by inputting the data base including climate, soil properties, crop stage, root density and root zone layer as well. The results in the case for 11th year oil palm tree on soil type ultisol in Central Kalimantan during the simulation climate data pointed out that the average root water is 3.46 mm/day and distributed 63% on 2st root zone. From the total water usage and the average production 14.19kg/month, it resulted the 1.053 m3/kg water footprint of FFB (76 % green water and 24% blue water).

Carbon Sequestration by Tropical Trees and Crops: A Case Study of Oil Palm

Carbon sequestration by photosynthetic organisms is the principal mechanism for the absorption of atmospheric CO2. Since the 1950s, however, the global carbon cycle has been distorted as increased anthropogenic CO2 emissions have greatly outstripped rates of carbon sequestration, with a 50% increase in atmospheric CO2 levels in less than a century, leading to perturbation of global climate systems and threatening food production and social stability. In order to address the current imbalance in CO2 flux, it is important to both reduce net emissions and promote sequestration. To address the latter issue, we need to better understand the roles of systems, such as natural forests, coastal wetlands, and tropical croplands, in carbon sequestration and devise strategies to facilitate net CO2 uptake. Carbon sequestration by tropical trees and crops already removes in excess of 1000 million tonnes of atmospheric CO2 annually but is threatened by anthropogenic activities such as deforestation and the drainage of carbon-rich peatland. Improvements in carbon sequestration can be achieved by policies such as growing tropical crops as part of agroforestry systems, enforcing limitations on deforestation and the use of peatland, and auditing the carbon impact of major cropping systems in order to focus on those crops that deliver both high yields and carbon efficiency. As an initial step in this process, a detailed case study is presented on the tropical tree crop, the African oil palm, Elaeis guineensis. This analysis includes a comparison of the carbon sequestration potential of oil palm with that of tropical forests and other oil crops, the biomass sequestration potential of oil palm and current and future strategies aimed at achieving net-zero carbon targets for oil palm and related crops.
