Land Improvement made from the Dasit Tuff Parent in Juhar Village, Juhar District, Karo Regency with land suitability for Cacao (Theobroma Cacao Q) plants

Introduction

Land is one of the most valuable natural resources for life, and its quality is significantly affected by the parent material. In this study, we focus on soil formed from the Dasit Tuff Material in Juhar Village, Juhar District, Karo Regency. Our primary objective is to identify the nature of the soil from the tuff and determine its land suitability for cocoa plants.

The Importance of Parent Material in Soil Formation

The parent material plays a crucial role in determining the characteristics of the soil. It is the source of the soil's mineral and organic matter, which in turn affects the soil's fertility, structure, and overall quality. In this study, we examine the Dasit Tuff Material as the parent material and its impact on the soil formed in Juhar Village.

Research Methods

In this study, a field study was conducted involving two pedons with different slopes, namely P1 with a slope of 21% and P2 with a slope of 11%. Each pedon was analyzed based on several parameters, including chemical, physics, morphology, mineralogy, and soil development. Data collection was done by observing the color of the soil, soil structure, soil consistency, and solum depth.

Field Observations and Laboratory Analysis

Field observations were conducted to collect data on the soil's physical and chemical properties. Laboratory analysis was further carried out to obtain data on soil texture, organic carbon content, pH, cation exchange capacity (CEC), cumulative nitrogen, total phosphorus, and clay minerals. This data is essential to determine the suitability of the soil for the growth of cocoa plants.

Soil Horizon Sequence and Characteristics

The results showed that the sequence of soil horizon in Pedon P1 consisted of A, A.2, B W1, B1/2, and C. While in Pedon P2, Horizon Land consisted of A, B W1, B W2, B W3, and C. These findings indicate that the soil formed from the Dasit Tuff Material has a complex horizon sequence, which is characteristic of soils with a high degree of weathering.

Land Suitability for Cocoa Plants

Cocoa (Theobroma Cacao Q) is a plant that requires soil with certain characteristics in order to grow optimally. Some factors that affect land suitability for cocoa plants include soil pH, nutritional content, and soil structure. Based on the results of the study, soil with a dasit tuff parent material in Juhar Village shows good potential for cocoa growth.

Factors Affecting Land Suitability for Cocoa Plants

Soil pH is one of the most critical factors affecting land suitability for cocoa plants. Cocoa plants prefer a slightly acidic to neutral soil pH, ranging from 6.0 to 7.0. The soil formed from the Dasit Tuff Material in Juhar Village has a pH range of 6.2 to 6.5, which is suitable for cocoa growth.

Nutritional Content and Soil Structure

Nutritional content and soil structure are also essential factors affecting land suitability for cocoa plants. The soil formed from the Dasit Tuff Material in Juhar Village has a high content of organic matter, which provides essential nutrients for cocoa growth. The soil structure is also suitable for cocoa growth, with a good balance of sand, silt, and clay particles.

Conclusion

Research on the trigger for land made from the Tuff Dasit parent in Juhar Village shows that the land has good potential for the suitability of cocoa plants. With a deep understanding of the characteristics of land, it is hoped that farmers can optimize their cocoa agricultural products. Through proper agricultural practices, it is hoped that there will be an increase in crops and sustainability in land management in Juhar Village, Juhar District, Karo Regency.

Recommendations

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

Conduct further research on the characteristics of the Dasit Tuff Material and its impact on soil formation.
Develop agricultural practices that optimize cocoa growth and sustainability in land management in Juhar Village.
Establish a cocoa plantation in Juhar Village to demonstrate the potential of the land for cocoa growth.

Limitations of the Study

This study has several limitations, including:

The study was conducted on a small scale, and further research is needed to confirm the findings.
The study only examined the characteristics of the Dasit Tuff Material and its impact on soil formation, and further research is needed to examine other factors affecting land suitability for cocoa plants.
The study did not examine the economic and social impacts of cocoa cultivation in Juhar Village.

Future Research Directions

Future research should focus on:

Conducting further research on the characteristics of the Dasit Tuff Material and its impact on soil formation.
Examining other factors affecting land suitability for cocoa plants, including climate, topography, and land use.
Investigating the economic and social impacts of cocoa cultivation in Juhar Village.
