The Influence of the Amelioration of Steel Slag and the Regulation of Ground Water Level on the Biological Properties of Oil Palm Plantations

Introduction

The sustainable management of peatlands is crucial for maintaining the health of oil palm plantations, which are a significant contributor to the global economy. Peatlands are unique ecosystems that are characterized by acidic, oxygen-poor conditions, which support a diverse range of plant and animal species. However, the intensive use of peatlands for oil palm plantations has led to the degradation of these ecosystems, resulting in the loss of biodiversity and the degradation of soil quality. In this study, we investigated the effect of the amelioration of steel slag and the regulation of ground water level on the biological properties of oil palm plantations in peatlands.

Background

Peatlands are formed from the accumulation of partially decayed plant material, which is rich in carbon and nutrients. However, the acidic and oxygen-poor conditions of peatlands make it difficult for plants to grow, and the lack of nutrients limits the diversity of plant species. The use of oil palm plantations in peatlands has led to the degradation of these ecosystems, resulting in the loss of biodiversity and the degradation of soil quality. The intensive use of peatlands for oil palm plantations has also led to the release of greenhouse gases, such as carbon dioxide and methane, which contribute to climate change.

Methodology

This study was conducted on the peatlands of PTPN IV Panai Jaya Palm Oil Plantation, North Sumatra, in collaboration with the Palm Oil Research Center (PPKS). The aim of the study was to implement sustainable management of peatlands through the utilization of steel slag as fertilizers and regulation of ground water level. Ameliorant administration is expected to increase nutrient levels in the soil, while groundwater regulation is aimed at preventing subsidies on peatlands. This study wants to evaluate the effect of the two interventions on soil biological properties, such as soil respiration, soil fauna population, fungi, and bacteria, as well as its relationship with the physical and chemical properties of the soil (temperature, pH, water content, and C/N).

The sampling method is carried out with three techniques: pit fall trap (trapping soil surface fauna), burlese tourgen (observing active soil fauna in the soil), and making holes (getting worms). The Pit Fall Trap method produces the highest number of fauna. The results showed that the addition of ameliorant did not have a significant impact on soil organisms, but the depth of ground water level had a significant influence on the population of fungi, bacteria, and soil fauna.

Results

Correlation analysis shows that soil fauna has a positive correlation with temperature, water content, and soil respiration, but negative correlation with pH and C/n. The bacterial population is positively correlated with water content and soil respiration, but has a negative correlation with temperature, pH, and C/N. The fungal population is negative with C/N, but correlates positively with temperatures, water content, pH, and soil respiration. The most commonly found fauna is rangrang ants (first place) and earthworms (second place).

Discussion

This study provides important information about the effect of peatland management on soil biodiversity. Groundwater regulation is proven to be a key factor that affects the population of soil organisms, while the addition of steel flag -flagged ameliorant in this study does not show a significant effect. These findings can be used as a basis for developing a more effective and sustainable peatland management strategy.

Importance of Ground Water Level Regulation

The results of this study emphasize the importance of regulating ground water level in maintaining the health of peat ecosystems. Maintained ground water level helps create suitable soil conditions for the survival of various soil organisms, including fungi, bacteria, and soil fauna. This is important to maintain soil fertility and increase peatland productivity for oil palm plantations.

Recommendation

Further research on the influence of steel grew up ameliorant on soil biology is needed to understand its optimal role in the management of peatlands. In addition, it is necessary to do more detailed analysis of the types of soil fauna found and their role in the peat ecosystem.

Conclusion

The regulation of ground water level is the main factor that affects the biological nature of peat soils. Through proper management, peat ecosystems can be maintained and support the productivity of oil palm plantations in a sustainable manner.

Future Directions

This study highlights the importance of regulating ground water level in maintaining the health of peat ecosystems. Further research is needed to understand the optimal role of steel slag ameliorant in the management of peatlands. Additionally, more detailed analysis of the types of soil fauna found and their role in the peat ecosystem is necessary to develop a more effective and sustainable peatland management strategy.

Limitations

This study has several limitations. Firstly, the study was conducted on a small scale, and the results may not be generalizable to other peatlands. Secondly, the study only investigated the effect of steel slag ameliorant and ground water level regulation on soil biological properties, and did not consider other factors that may affect peatland management, such as climate change and land use change.

Implications

The findings of this study have several implications for peatland management. Firstly, the study highlights the importance of regulating ground water level in maintaining the health of peat ecosystems. Secondly, the study suggests that the addition of steel slag ameliorant may not be effective in improving soil biological properties, and further research is needed to understand its optimal role in the management of peatlands. Finally, the study emphasizes the need for more detailed analysis of the types of soil fauna found and their role in the peat ecosystem to develop a more effective and sustainable peatland management strategy.
