Introduction

Coffee is a vital agricultural commodity in Mandailing Natal Regency, North Sumatra, with significant economic value. However, the land conditions in this region are diverse, influenced by topographic, climate, and temperature factors. This diversity encourages research to understand the characteristics of soil and their impact on the productivity of coffee plants. The aim of this study is to evaluate the chemical properties of soil on coffee land in several districts in Mandailing Natal Regency.

Background

Coffee is a major crop in Mandailing Natal Regency, with many farmers relying on it as a source of income. However, the productivity of coffee plants in this region is often affected by various factors, including soil conditions. Soil is a critical component of the ecosystem, and its chemical properties play a significant role in determining the fertility and productivity of crops. Understanding the chemical properties of soil is essential for developing effective strategies to improve coffee productivity.

Methodology

This study was conducted in several sub-districts in Mandailing Natal Regency, with data obtained through surveys and sampling of soil using purposive random sampling. Six chemical parameters of the soil were examined: pH, organic carbon, total nitrogen, phosphate available, cation exchange capacity (KTK), and base saturation. Data were analyzed using a classic assumption test, normality test, linearity test, correlation analysis, and quadratic regression.

Results

The results of this study showed that the relationship between soil chemical characteristics and coffee productivity was insignificant. This means that the soil parameters tested do not directly affect coffee yields. This finding suggests that other factors may be more dominant in determining coffee productivity in Mandailing Natal.

Deeper Analysis

A deeper analysis of the results revealed that other factors may be more influential in determining coffee productivity. These factors can be categorized into three groups:

Biological Factors

Plant health: The health of coffee plants is critical in determining their productivity. Factors such as disease and pest attacks can significantly impact plant health and productivity.
Soil microorganisms: Soil microorganisms play a vital role in decomposing organic matter and making nutrients available to plants. An imbalance in soil microorganisms can affect plant growth and productivity.
Pest and disease control: Effective control of pests and diseases is essential in maintaining plant health and productivity.

Physical Factors

Soil structure: The structure of the soil affects its ability to retain water and nutrients. A well-structured soil can improve plant growth and productivity.
Drainage: Proper drainage is essential in preventing waterlogged soil, which can lead to root rot and other problems.
Aeration: Adequate aeration is necessary for healthy root growth and plant development.

Management Factors

Cultivation system: The cultivation system used can significantly impact plant growth and productivity. Factors such as crop rotation, intercropping, and monoculture can affect soil health and plant productivity.
Fertilizer use: The use of fertilizers can impact soil health and plant productivity. Overuse of fertilizers can lead to soil degradation and environmental pollution.
Disease and pest control: Effective control of diseases and pests is essential in maintaining plant health and productivity.

Recommendation

This study provides an initial picture of soil chemical conditions in the study area. To increase coffee productivity, it is recommended to:

Continuing Research

Conducting further research by reviewing other factors that might affect coffee productivity, such as biological and management factors.
Investigating the impact of climate change on coffee productivity in Mandailing Natal Regency.

Pay Attention to Biological Factors

Promoting the use of technology, such as precision agriculture, to improve coffee productivity.

By understanding the factors that influence coffee productivity, it is expected to improve the quality and quantity of coffee production in Mandailing Natal. This will have a positive impact on the regional economy and the welfare of the community.

Conclusion

This study evaluated the chemical properties of soil on coffee land in several districts in Mandailing Natal Regency. The results showed that the relationship between soil chemical characteristics and coffee productivity was insignificant. This suggests that other factors, such as biological, physical, and management factors, may be more influential in determining coffee productivity. The study provides recommendations for improving coffee productivity, including continuing research, paying attention to biological factors, improving the physical condition of the soil, and increasing farmers' knowledge. By implementing these recommendations, it is expected to improve the quality and quantity of coffee production in Mandailing Natal.
