Palm Kernel Shell Biochar comes from palm kernel shells that undergo pyrolysis under limited oxygen. A study in the Journal of Oil Palm Research (2019) highlights its strong potential to improve soil quality while simultaneously reducing carbon emissions.
How Is Palm Kernel Shell Biochar Produced?
The production of Palm Kernel Shell Biochar involves pyrolysis at 400°C – 600°C for 30 – 90 minutes. The results are clear: carbon content rises significantly from 46% to 73%, while hydrogen and oxygen decrease. These changes make the biochar more stable in soil, thanks to its low H/C and O/C ratios.
The transition is evident: the higher the temperature and the longer the duration, the greater the potential for carbon sequestration.
Why Is Palm Kernel Shell Biochar Beneficial for Agriculture?
This biochar does more than strengthen soil structure it actively boosts agricultural productivity.
- Neutralizing acidic soils
With its alkaline pH (9.3 – 12.0), biochar reduces soil acidity and improves nutrient uptake for crops. - Enhancing water retention
Water holding capacity increases from 2.23 g/10 g (raw PKS) to more than 6 g/10 g in biochar. This means soils retain moisture longer, which is especially valuable in dry or sandy conditions. - Improving cation exchange capacity (CEC)
At 400°C for 60 minutes, biochar reached a CEC of 4.44 cmol/kg. This indicates better soil ability to store and release nutrients.
The transition is straightforward: from poor and acidic soils to more fertile, nutrient-rich farmland with the help of biochar.
How Does Palm Kernel Shell Biochar Help Reduce Carbon Emissions?
This biochar also plays a vital role in climate change mitigation. At 500°C for 90 minutes, it can store up to 0.63 kg CO₂ per kg PKS.
Because of its high stability, this stored carbon can remain in the soil for centuries. That is why palm-based biochar is increasingly recognized as a natural strategy for reducing greenhouse gases.
Conclusion: Why Should We Consider This Biochar?
Biochar from palm kernel shells delivers two major benefits:
- As a soil amendment, it improves fertility, nutrient availability, and water retention.
- As a long-term carbon sink, it supports global efforts to mitigate climate change.
The optimal production process is around 500°C for 60 – 90 minutes, which creates a stable, nutrient rich, and highly effective biochar for soil improvement.
In short, this palm based biochar is not just a byproduct of the palm oil industry; rather, it is a practical solution for sustainable agriculture and a healthier planet.
