Introduction

Land classification is a crucial aspect of understanding the properties and characteristics of soil in a particular region. It provides valuable information that can be used for land use planning, land management, and agricultural development. This study aims to classify the types of soil in Sihiong Village, Sinar Sabungan, and Lumban Lobu, Bonatua Lunasi District, Toba Samosir Regency based on the 2010 Land Taxonomy.

Methodology

This study was conducted by direct observation in the field and laboratory analysis in the Laboratory of Soil Chemistry, Research Center and Technology, Faculty of Agriculture, University of North Sumatra, Medan. Field observations were carried out in three locations, namely:

Profile I in Sihiong Village

Location: Sihiong Village
Slope: 21% (waves)
Height: 1024 meters above sea level (masl)
Physical properties observed: Color, structure, texture, consistency, roots, and effective depth

Profile II in Sinar Sabungan Village

Location: Sinar Sabungan Village
Slope: 15% (waves)
Height: 991 meters above sea level (masl)
Physical properties observed: Color, structure, texture, consistency, roots, and effective depth

Profile III in Lumban Lobu Village

Location: Lumban Lobu Village
Slope: 15% (waves)
Height: 1071 meters above sea level
Physical properties observed: Color, structure, texture, consistency, roots, and effective depth

Laboratory Analysis

Soil samples of each horizon were taken to be analyzed in the laboratory. Laboratory analysis included:

Soil texture
Content weight
C-organic
Basic exchange (Ca2+, Mg2+, K+, and Na+)
H2O pH
KCL pH
Kation Exchange Capacity (KTK)

Results

The results showed land classification based on the 2010 land taxonomy in each village as follows:

Sihiong Village

Order: Inceptisols
Sub Order: Udepts
Great Group: Humudepts
Sub Group: Fluventic Humudepts

Sinar Sabungan Village

Order: Inceptisols
Sub Order: Udepts
Great Group: Humudepts
Sub Group: Pachic Humudepts

Lumban Lobu Village

Order: Entisol
Sub Order: Orthent
Great Group: Udorthent
Sub Group: Typic Udorthent

Additional Analysis and Explanation

Land classification based on land taxonomy 2010 provides important information about the properties of soil that can affect its use and management.

Inceptisols

Definition: A young land with limited profile development
Characteristics: Horizon B that has not been fully developed and is rich in organic material

Udepts

Definition: Subordo Inceptisols which shows the development of further horizon B
Characteristics: Further development of horizon B

Humudepts

Definition: Great Group Inceptisols which have horizon B which is rich in organic material and has the ability to hold good water
Characteristics: Horizon B which is rich in organic material and has the ability to hold good water

Entisol

Definition: A very young soil with an undeveloped soil profile
Characteristics: Generally formed from new parent materials, such as alluvial deposits

Orthent

Definition: Subordo Entisol which shows the minimum development of soil profile
Characteristics: Minimum development of soil profile

Udorthent

Definition: Great Group Entisol which has a thick Horizon A and fine textured
Characteristics: Thick Horizon A and fine textured

Importance of Land Classification Information

Land classification information is very useful for:

Land Use Planning

Definition: Knowing the type of soil can help in determining the right land use
Importance: Helps in determining the right land use

Land Management

Definition: Land classification provides information about the properties of soil that needs to be considered in management, such as fertility, drainage, and erosion
Importance: Provides information about the properties of soil that needs to be considered in management

Agricultural Development

Definition: Understanding the type of soil helps in choosing the appropriate type of plant and determines the right cultivation method
Importance: Helps in choosing the appropriate type of plant and determines the right cultivation method

Conclusion

This study succeeded in classifying land in Sihiong Village, Sinar Sabungan, and Lumban Lobu based on the 2010 land taxonomy. The results of this study showed that each village has a different type of land, which is influenced by environmental factors. This land classification information can be used for land use planning, land management, and agricultural development in the region.

Q: What is land classification?

A: Land classification is the process of categorizing land into different types based on its physical and chemical properties. It provides valuable information that can be used for land use planning, land management, and agricultural development.

Q: Why is land classification important?

A: Land classification is important because it helps in determining the right land use, provides information about the properties of soil that needs to be considered in management, and helps in choosing the appropriate type of plant and determines the right cultivation method.

Q: What are the different types of land classification?

A: The different types of land classification include Inceptisols, Udepts, Humudepts, Entisol, Orthent, and Udorthent.

Q: What are the characteristics of Inceptisols?

A: Inceptisols are young lands with limited profile development. They have a horizon B that has not been fully developed and is rich in organic material.

Q: What are the characteristics of Udepts?

A: Udepts are suborders of Inceptisols that show the development of further horizon B. They have further development of horizon B.

Q: What are the characteristics of Humudepts?

A: Humudepts are great groups of Inceptisols that have horizon B which is rich in organic material and has the ability to hold good water. They have horizon B which is rich in organic material and has the ability to hold good water.

Q: What are the characteristics of Entisol?

A: Entisol is a very young soil with an undeveloped soil profile. It is generally formed from new parent materials, such as alluvial deposits.

Q: What are the characteristics of Orthent?

A: Orthent is a suborder of Entisol that shows the minimum development of soil profile. It has minimum development of soil profile.

Q: What are the characteristics of Udorthent?

A: Udorthent is a great group of Entisol that has a thick Horizon A and fine textured. It has a thick Horizon A and fine textured.

Q: How can land classification information be used?

A: Land classification information can be used for land use planning, land management, and agricultural development.
