The Role of Biochar in Increasing Palm Oil Productivity, Among the Use of Superior Seeds and Replanting

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. 

Biochar as Deforestation Solution in Palm Oil Plantations and EUDR

The development of the palm oil industry and its plantations in Indonesia is very rapid, especially in the last 10 years and currently the area of ​​Indonesian palm oil plantations is estimated to reach 17 million hectares. As the largest vegetable oil producing plant in the world and the largest palm oil plantation area in the world, of course palm oil has a strategic value in the Indonesian economy. The average speed of Indonesian palm oil plantation area is 6.5% per year or equivalent to around 1 million hectares per year for the last 5 years, while the increase in palm oil fruit production or FFB (fresh fruit bunches) is only 11% on average.

Even the largest land expansion occurred in 2017, which increased by 2.8 million hectares. From 2015 to 2019, the total area of ​​palm oil plantations increased by 3.7 million hectares. The extensification or expansion of palm oil plantations has been widely "accused" and has become the focus of the world as a result of the conversion of forest land, resulting in a lot of deforestation to be converted into palm oil plantations.

Pressure from the European Union in particular, due to these conditions, has worsened the image of Indonesian palm oil, which in turn has affected the selling price of palm oil products, both CPO and its derivative products. Improving this image is also not easy. One effective effort is to stop the extensification efforts so that forest land remains forest land and does not turn into oil palm plantations. The European Union on Deforestation-free Regulation (EUDR), which will come into effect on December 30, 2024, as an effort to prevent deforestation, is also an important consideration. The regulation requires consumers and producers along the supply chain of certain commodities to conduct due diligence and risk assessments to ensure that their products do not contribute to deforestation. The EUDR also applies a tiered inspection and penalty system based on the level of risk perceived in the country of origin.

With the extensification of oil palm land of more than 1 million per hectare each year but the increase in oil palm fruit production is only 11%, it is certainly less attractive and must be avoided, especially with the world's spotlight on the increasingly rapid deforestation. This also increasingly indicates the low productivity of palm oil plantations. In fact, by improving soil quality, palm oil fruit productivity can be increased significantly and the opening of new land for the creation of palm oil plantations can be avoided. Biomass waste in palm oil plantations and in palm oil mills can be used for biochar production as a solution to this problem.

With the increase in productivity of fresh fruit bunches (FFB) with the use of biochar, new palm oil plantations do not need to be opened again. Assuming an average increase in productivity of 20%, CPO production will also increase by 20% or equivalent to 2 million tons. This increase will be equivalent to opening new land covering an area of ​​more than 2 million hectares. Of course, it is not a small area of ​​land. With a 20% increase in production, it is very likely that national needs for CPO in particular have been met and so too for the export market. Another advantage of using biochar is as a climate solution as carbon sequestration/carbon sink. So the two main problems in the palm oil industry in the form of increasing productivity and climate change resilience can be overcome at once with the application of biochar.
