Management Of Ground Water Levels And Flag Of Steel To The Physical Properties Of Peat Related To Carbon Emissions In Oil Palm Plantations
Introduction
The management of groundwater levels and the application of steel slag have become increasingly important in maintaining the physical properties of peat soils in oil palm plantations. Peat soils are a crucial component of these plantations, as they provide a unique environment for oil palm growth. However, the high water content in peat soils can lead to increased carbon emissions, which contribute to climate change. In this study, we aimed to investigate the impact of groundwater management and steel slag application on the physical properties of peat soils and carbon emissions in oil palm plantations.
Background
Oil palm plantations are a significant contributor to the global economy, with Indonesia and Malaysia being the largest producers. However, the production of palm oil has been linked to deforestation, habitat destruction, and climate change. Peat soils, which cover approximately 25% of the world's tropical forests, are a critical component of these plantations. Peat soils are characterized by high water content, which can lead to increased carbon emissions through the process of peat decomposition. The management of groundwater levels and the application of steel slag can help mitigate these emissions and maintain the physical properties of peat soils.
Research Methodology
This study was conducted on a six-year-old oil palm plantation land using a split plot design. The design included two treatments: groundwater management in three levels as the main treatment and four doses of slag steel as additional treatment. Soil sampling was carried out at depths of 0-2 cm, 2-5 cm, 5-10 cm, and 10-50 cm to measure the actual soil water content. Observations of the soil were also made at depths of 0-10 cm, 10-20 cm, 20-30 cm, and 30-40 cm.
Carbon Emission Measurement
Carbon emissions were measured using the Close Chamber Technique method analyzed with micro gas chromatograph (micro-GC). Assessment of irreversible drying in peat was done by comparing actual soil water content with critical water content.
Research Results
The results showed that on plots with groundwater levels above 80 cm and low doses of slag application, vulnerability to drought did not return, especially in the layer of 0-10 cm, even in the layer of a tree disk in the range of 0-20 cm. In this case, the existence of land cover plants function significantly to reduce the risk of drought in peat soil during the dry season, thereby protecting soil from uncovered drought.
Improvement of the physical properties of peat was also identified, in which the application of steel slag had a significant positive effect based on Pearson's correlation analysis at the 5% confidence level. In this case, the measured peat volume weight reached 0.25 g/cm³ with correlation (r = -0.61), ash content 4.69% (R = -0.77), and C-Organic 48.68% (R = -0.77). In addition, the management of groundwater levels in a range of 40-60 cm contributed to reducing CO₂ flux from peatlands in oil palm plantations (R = 0.73).
Research Implications
This study highlights the importance of groundwater management and the application of slag steel in maintaining the physical properties of peat soils on oil palm plantations. By understanding the interaction between the depth of groundwater and the use of additional materials such as slag steel, farmers can optimize the production of palm oil while minimizing carbon emissions.
This is important not only for the sustainability of the palm oil industry but also for climate change mitigation efforts. By reducing carbon emissions, agriculture can contribute to the achievement of global environmental goals and maintain the balance of ecosystems.
Conclusion
Overall, this finding provides valuable insights for farmers, researchers, and policymakers on better and responsible peatland management in supporting the growth of sustainable palm oil industries. The management of groundwater levels and the application of steel slag can help mitigate carbon emissions and maintain the physical properties of peat soils. This study highlights the importance of integrated approaches to sustainable agriculture, which consider the social, economic, and environmental aspects of production.
