Land Classification in the USU Tambunan A Experimental Garden, Salapian District, Langkat Regency based on the 2014 Land Taxonomy

Introduction

Land classification is a crucial aspect of understanding the potential of soil in supporting plant growth and agricultural production. The University of North Sumatra (USU) Tambunan A experimental garden, located in Salapian District, Langkat Regency, is a prime location for studying land classification. This study aims to classify soil ranging from the order level to the subgroup, using the 2014 land taxonomy. The research location is in the trial garden of the University of North Sumatra (USU) Tambunan A, which is located in Salapian District, Langkat Regency, takes place from May to October 2017.

Methodology

The methods used in this study include a description of the soil profile to determine the morphological nature, as well as laboratory analysis for measuring the physical and chemical properties of the soil. Soil samples are taken from each horizon on a different profile, and tested in the laboratory to analyze the soil texture, content density, pH H2O, KCl pH, P2O5, organic carbon content, and bases can exchange (Ca²⁺, Mg²⁺, K⁺, and Na⁺), including cation exchange capacity (KTK). The laboratory analysis is essential in determining the physical and chemical properties of the soil, which are crucial in understanding the potential of the soil in supporting plant growth.

Results

The results revealed that the land classification in the USU Tambunan A experimental garden, based on the 2014 land taxonomy, showed that all profiles (profile 1 to profile 5) were classified as inceptisols, UDEPTS, Humudepts, and Humic Psammentric Dystrudepts. This shows consistency in the nature of the soil at that location, where similar characteristics are found on each profile tested. The classification of inceptisols indicates that the soil is relatively young and has a layer that is not too degraded, which makes it possible to plant various types of plants.

Analysis of Results

Soil classification becomes important in the context of agriculture and management of natural resources, especially to understand the potential of soil in supporting plant growth. Inceptisols is a type of soil that is relatively young and has a layer that is not too degraded, which makes it possible to plant various types of plants. Meanwhile, Humudepts is one of the subcategories that shows that the soil has a significant organic matter content, so as to increase soil fertility. Classification of Humic Psammentric Dystrudepts shows the presence of sand soil with better humidity, although it contains fewer nutritional elements compared to clay. This makes it need special attention in agricultural practice, for example by adding organic fertilizer to improve soil structure and nutrition.

Discussion

The results of this study have significant implications for agricultural practice and management of natural resources. The classification of inceptisols indicates that the soil is relatively young and has a layer that is not too degraded, which makes it possible to plant various types of plants. The classification of Humudepts shows that the soil has a significant organic matter content, which can increase soil fertility. The classification of Humic Psammentric Dystrudepts shows the presence of sand soil with better humidity, although it contains fewer nutritional elements compared to clay. This makes it need special attention in agricultural practice, for example by adding organic fertilizer to improve soil structure and nutrition.

Conclusion

From the results of this study, it is clear that the USU Tambunan A experimental garden has a fairly consistent soil characteristics and can be utilized for various agricultural businesses. This deep understanding of the classification and nature of this land is very important for sustainable land management. The implementation of agricultural engineering in accordance with the nature of the soil will help increase land productivity and maintain the health of agricultural ecosystems in the area. Further research needs to be done to explore more about how effective soil management can affect plant growth and agricultural production in the future.
