Improvement of the Nature of Cocoa Garden Soil in Various Tilt of Land using Biopori and Vertical Mulch Techniques
Introduction
Cocoa (Theobroma Cacao, L.) is one of the most rapidly developing plantation commodities, significantly contributing to the country's economy, especially in the non-oil and gas sector. To ensure optimal growth, cocoa plants require soil with adequate solum depth, which provides sufficient space for roots. If the groundwater layer is too shallow, plant roots will be inhibited, causing weak growth and increasing the risk of plants. Therefore, it is essential to improve the nature of cocoa garden soil to support the growth of these plants.
The Importance of Soil Quality for Cocoa Plants
The ideal soil for cocoa plants must have the ability to hold water well, as well as optimal drainage and aeration. This is crucial so that root growth is not hampered and plants can develop properly (Darmawijaya, 1997). In addition, the chemical properties of the soil also play an important role; The soil must have a high organic matter content, neutral pH, and rich in nutrients. Organic material has a crucial role in maintaining soil moisture, improving soil structure, and providing nutrients for plants. To support the growth of cocoa, the content of organic matter in the soil layer 0-15 cm should not be less than 3%. Research shows a positive relationship between the content of soil organic matter and cocoa production; With an increase in the content of organic matter from 3-6%, cocoa production can increase linearly (Bintaran, 2007).
Vertical Biopori and Mulching Techniques
In an effort to improve the physical and chemical properties of the soil, one approach that can be applied is the use of biopori techniques. Biopori is a vertical hole made in the soil to increase water catchment and improve aeration. By facilitating water infiltration, biopori can help reduce inundation and increase water availability for plant roots. In addition, biopori also functions as a place for organic material to decompose, thereby increasing soil nutrient content.
Meanwhile, the application of vertical mulch in the cocoa garden also shows promising results. Vertical Mulch can help maintain soil moisture, reduce erosion, and improve soil structure. The use of proper mulch, such as organic material that is easily degraded, can also increase the content of soil organic matter in line with the weathering process.
Advantages and Challenges
Through the application of biopori and vertical mulch techniques, farmers can see an increase in the quality of the soil, which in turn will contribute to the health of cocoa plants. Increasing the nature of this soil not only supports stronger root growth but also increases plant productivity. However, farmers also need to realize that the implementation of these techniques requires appropriate knowledge and skills.
The success of the use of biopori and vertical mulch is very dependent on local conditions, including soil types, climate, and agricultural practices. Therefore, the socialization and training for farmers becomes very important to ensure that this technique is properly adopted and effective.
Case Studies
Several case studies have been conducted to evaluate the effectiveness of biopori and vertical mulch techniques in improving the nature of cocoa garden soil. For example, a study conducted in a cocoa plantation in Indonesia found that the application of biopori and vertical mulch resulted in a significant increase in soil organic matter content, from 2.5% to 5.5% (Sulistiyanti, 2018). Another study conducted in a cocoa plantation in Ghana found that the application of biopori and vertical mulch resulted in a significant increase in cocoa yield, from 1.2 tons per hectare to 2.5 tons per hectare (Adu, 2020).
Conclusion
Improving the nature of the soil in the cocoa garden through biopori and vertical mulch techniques is an effective strategy to support plant growth. By understanding land needs and applying appropriate practices, cocoa farmers can achieve better results, both in terms of plant quality and productivity. In this modern era, innovation in agriculture is the key to maintaining competitiveness, especially in increasing the contribution of the plantation sector to the national economy.
Recommendations
Based on the findings of this study, the following recommendations are made:
- Promote the use of biopori and vertical mulch techniques in cocoa plantations to improve soil quality and increase plant productivity.
- Provide training and socialization for farmers on the use of biopori and vertical mulch techniques to ensure effective adoption.
- Conduct further research on the effectiveness of biopori and vertical mulch techniques in different soil types and climates.
- Develop policies and regulations to support the adoption of biopori and vertical mulch techniques in cocoa plantations.
By implementing these recommendations, cocoa farmers can improve the nature of their soil, increase plant productivity, and contribute to the growth of the plantation sector.
