Introduction

The reclamation of peat land into agricultural areas often leads to a rapid process of decomposition of organic material, resulting in the loss of most of the mass of organic matter, which is converted into carbon dioxide (CO2). This process poses a significant threat to the sustainability of agricultural businesses on peatlands. One of the characteristics of peat soil is its high level of acidity, which is caused by the presence of organic acids produced through the process of anaerobic decomposition. This high acidity condition often acts as an inhibiting factor for plant growth. Therefore, a strategy is needed to overcome acidity and slow down decomposition. One of the efforts that can be done is to give lime (calcification) and CuSO4. Both of these treatments serve to reduce the decomposition rate of organic matter and suppress the reactivity of organic acids that cause the acidity of peat soils.

Background

Peatlands are unique ecosystems that play a crucial role in the global carbon cycle. They are characterized by their high water table, acidic conditions, and high levels of organic matter. The decomposition of organic matter in peatlands is a slow process, which is facilitated by the presence of microorganisms such as bacteria and fungi. However, when peatlands are reclaimed for agricultural purposes, the decomposition process is accelerated, leading to the loss of organic matter and the release of carbon dioxide into the atmosphere. This process not only contributes to climate change but also poses a significant threat to the sustainability of agricultural businesses on peatlands.

Methodology

This study was conducted in the Environmental Laboratory of the Environmental Impact Control Agency (Bapedal) of the North Sumatra Region, using Typic Haplosaprist obtained from the Ajamu II Ptpn IV Garden, Bilah Hilir District, Labuhan Batu. The experimental design used was a separate plot (RPT), which consisted of two factors with three replications. The calcification factor is tested at four levels, namely K0 (without giving CaCO3), K1 (Giving CaCO3 is equivalent to pH 5), K2 (Giving CaCO3 equivalent to pH 5.5), and K3 (Giving CaCO3 is equivalent to pH 6). In addition, the provision of CuSO4 is also carried out at four levels, namely C0 (0 ppm Cu), C1 (587 ppm Cu), C2 (1174 ppm Cu), and C3 (1761 ppm Cu).

Variables Observed

The variables observed in this study include pH, organic C content, total N, C/N ratio, and Cation Exchange Capacity (KTK) on the 30th and 60th incubation. In addition, the content of Humic C-acid and Fulvik C-acids is measured on the 60th day of incubation, as well as CO2 observations made every 10 days until the 60th day. All data obtained are analyzed using variety analysis and Duncan Difference Difference Test (DMRT).

Results

The results of this study showed that calcification significantly increased the soil pH in observations of the 30th and 60th days after incubation and increased the levels of Humic C-acid on the 60th day. Nevertheless, calcification also significantly reduced the total N in the two observations and increased the soil CEC. Conversely, the provision of CuSO4 has proven to significantly reduce soil pH on the 60th day and reduce CO2 emissions released in observations of the 50th day.

Discussion

The results of this study provide valuable insights into the effects of calcification and giving CuSO4 on the acidity and decomposition of peat soils. The increase in soil pH and the levels of Humic C-acid as a result of calcification suggest that this treatment can help to reduce the acidity of peat soils and promote the formation of humic acids. However, the reduction in total N and the increase in soil CEC as a result of calcification suggest that this treatment may also have negative effects on the fertility of peat soils.

Conclusion

In conclusion, this study provides a clear picture of the effect of calcification and giving CuSO4 on the acidity and decomposition of peat soils. The findings of this study have important implications for the development of a more effective peat soil management strategy in order to increase agricultural productivity without sacrificing environmental sustainability. Further research is needed to explore the long-term effects of calcification and giving CuSO4 on peat soils and to develop more effective strategies for managing peat soils.

Recommendations

Based on the findings of this study, the following recommendations are made:

  • Calcification: Calcification can be used as a treatment to reduce the acidity of peat soils and promote the formation of humic acids. However, the levels of calcification should be carefully controlled to avoid negative effects on the fertility of peat soils.
  • Giving CuSO4: Giving CuSO4 can be used as a treatment to reduce CO2 emissions and promote the formation of humic acids. However, the levels of CuSO4 should be carefully controlled to avoid negative effects on the fertility of peat soils.
  • Integrated Management: An integrated management approach that combines calcification and giving CuSO4 with other treatments such as fertilization and irrigation may be more effective in promoting the sustainability of agricultural businesses on peatlands.

Future Research Directions

Further research is needed to explore the long-term effects of calcification and giving CuSO4 on peat soils and to develop more effective strategies for managing peat soils. Some potential research directions include:

  • Long-term Effects: The long-term effects of calcification and giving CuSO4 on peat soils should be explored to determine whether these treatments can promote the sustainability of agricultural businesses on peatlands.
  • Integrated Management: The effectiveness of integrated management approaches that combine calcification and giving CuSO4 with other treatments such as fertilization and irrigation should be explored.
  • Soil Fertility: The effects of calcification and giving CuSO4 on soil fertility should be explored to determine whether these treatments can promote the fertility of peat soils.
