Characterization and Classification of Soils Originating from Carbon and Tertiary Permo Formations in the South Tapanuli Area

Soil characterization and classification are crucial aspects of understanding the properties and behavior of soils, which in turn affect land use and resource management. In the South Tapanuli area, the presence of carbon and tertiary permo formations has led to the development of unique soil characteristics. This study aims to investigate the physical, chemical, and mineralogical properties of soils formed from these formations and classify them using the 1999 USDA land taxonomy key.

Understanding the Study Area

The study was conducted in three different locations in South Tapanuli: Padang Sidempuan (P2), Gunung Tua (P3), and Binanga (P4). Each location was chosen for its unique geological and topographical features. Padang Sidempuan is located in the Permo Carbon Formation, precisely in Panumpuan Julu Village, 25 km from the city center. Gunung Tua is situated in the Paleogen Formation, in Padang Garugur Village, 55 km from the city. Binanga is located in the Neogen Formation, in Bahal Batu Village, 87 km from the city.

Land Analysis from Three Locations

This study examined the physical, chemical, and mineralogical properties of soils from the three locations. The results are presented below:

Located on a slope with a slope of 5%, Pedon 2 has a clay texture with a surface color of 5 YR 46 (yellowish red). This soil is loose to a depth of 20 cm, with a pH H₂O ranging from 4.72 - 4.96. Cation Exchange Capacity (KTK) ranges from 9.58 - 20.05 ME/100 g of soil, with basic saturation 11.61 - 30.06%. Pedon 2 contains C -organic content of 0.15 - 1.08%, and AL saturation 32.68 - 60.5%. Based on these characteristics, Pedon 2 is classified as oxisol with sub-order udoxo, large group kandudox, sub-group typic kandudox, and family Isohyperthermik, Typic Kandudox.

Pedon 3 (Old Mountain)

Located on a slope with a slope of 10%, Pedon 3 has a clay texture with a surface color of 2.5 YR 25/1 (Black). This land is firm to a depth of 205 cm, with a pH H₂O ranging from 5.75 - 7.79. Circles of land ranges from 38.56 - 46.78 ME/100 g of land, base saturation 2.98 - 102.91%, and C -organic 0.23 - 1.00%. Pedon 3 has a content density (BD) of more than 1 (depth of 0 - 58 cm) and AL saturation is 0%. Based on this characteristic, Pedon 3 is classified as inceptisol with sub-order udepts, large group eutrudepts, sub-group fluventic eutrudepts, and family Smooth, Isohyperthermik, Fluventic Eutrudepts.

Pedon 4 (Binanga)

Located on a slope with a slope of 3%, Pedon 4 has a clay texture with a surface color of 7.5 YR 5/8 (dark brown). This soil is loose to a depth of 107 cm, with a pH H₂O ranging from 4.27 - 4.95. COMPLY LAND ranges from 2.57 - 5.66 ME/100 g of soil, base saturation 9.50 - 23.95%, and C -organic 0.19 - 1.27%. Pedon 4 has a content density (BD) of more than 1 (depth of 0 - 60 cm) and AL saturation 65.36 - 77.08%. Based on these characteristics, Pedon 4 is classified as ultisol with sub-ordo uduss, large group kanduduss, sub-group Arenic Kandiuduss, and Family Sandy clay, Kwarsa murky, Isohyperthermik, Arenic Kandudults.

Conclusion and Implications

The results of this study show that the soils in South Tapanuli originating from the carbon and tertiary permo formations have different characteristics. This is influenced by factors such as geology, climate, and topography. The different land classification has important implications for land use and land resource management in the area.

Knowledge of soil characteristics is very important to determine the right strategy to increase land productivity, prevent land degradation, and maintain environmental sustainability. Further research is needed to learn more about the effect of carbon and tertiary permo formations on the physical, chemical, and mineralogy of soil, as well as for the development of more appropriate land use and recommendations.
