Palm oil productivity continues to be pushed to its most optimal point. This is because it is to meet the increasing needs, especially the mandatory B-50 biodiesel program. Of course, efforts to optimize productivity are not easy and instant. Although the key points for its realization have also been mapped, namely by replanting old palm oils, using superior seeds and intensification, the practice also requires the right method or approach and takes time. Replanting old palm oils is still very slow and has many obstacles, while the use of superior seeds has received more attention and continues to be encouraged. The analogy of using superior seeds is like comparing local cattle and superior breeds. So no matter how well the Javanese cow is cared for, its weight will not match that of the Limousin cow. Likewise with palm oil seeds.
Land intensification efforts through optimizing inputs, technology and modern cultivation methods also still need to be developed. Meanwhile, extensification or land expansion should be avoided or slowed down as much as possible, for more details, read here. Biochar can have an important role in this area of intensification. Apart from the application of biochar it will improve soil health, which is an important prerequisite for plants to be able to produce optimally, it is also very environmentally friendly because the raw material for biochar is from renewable sources, namely biomass and increases fertilization efficiency (NUE = Nutrient Use Efficiency). And even the application of biochar is also a climate solution, namely as carbon sequestration. Optimizing productivity can be done by applying biochar plus using superior seeds using modern and environmentally friendly agricultural methods. So basically optimization is a comprehensive and measurable effort.
Indonesia contributes 25% to the world's vegetable oil supply, making it a key actor in the stability of the world's vegetable oil supply. With this position, any changes in production, export policies and Indonesia's domestic dynamics will directly impact prices and international market balance. Indonesia is currently the largest or number one producer of palm oil in the world, but it is not the best or most productive because its productivity is not yet optimal. Compared to neighboring countries, namely Malaysia, it is still inferior and slightly superior to Thailand, even though geographical factors, namely the climate in Indonesia, are much more supportive. Currently, Indonesia's CPO productivity is around 3.3 tons/hectare, while Malaysia's is around 3.8 tons/hectare, while Thailand's is around 3 tons/hectare.
Yield gap, namely the difference or gap between actual production and maximum production potential, is sometimes quite large. Several main factors that trigger yield gaps include non-optimal environmental factors such as drought conditions, to errors in cultivation practices such as errors in land clearing and planting, as well as inaccuracies in diagnosis and fertilizer recommendations. This yield gap must be minimized so that palm oil productivity can be maximized.
Sometimes the role of biochar cannot be found or seen directly in various efforts to increase palm oil productivity, but the application of biochar is very much in line with this goal. For example, the success of an palm oil replanting program depends, among other things, on the quality of seeds, fertilization, plant population and soil health. Soil health and fertilization factors can be closely related to biochar. And related to biofungicides to treat ganoderma fungus disorders, biochar can be used as a carrier formulated with other elements such as humus, amino acids, humates, hormones and so on. And because the only effective way to control the ganoderma fungus is to introduce its natural enemies in the form of biofungicides based on Trichoderma spp and arbuscular mycorrhizal fungi into the soil. However, there are still many parties who do not have adequate knowledge regarding the application of biochar.
Apart from boosting production, implementing best management practices is also important to meet sustainability standards amidst increasing pressure from environmental issues. And the application of biochar is very much in line with that point. In fact, regarding low carbon palm oil technology in the application of biochar, it is very relevant to the CECC (Controlled Emission Composting Chamber) and for more details on the application of biochar for composting, read here. Meanwhile, the trend of fertilization in palm oil plantations with the application of slow release fertilizer is also very relevant to biochar, for more details, read here.
