Erosion Selectivity Study Of 25 -year -old Rubber Plants In Lau Damak Village, Bahorok District, Langkat Regency
Introduction
Rubber is a highly sought-after commodity that has been cultivated by communities worldwide, including in Lau Damak Village, Langkat Regency. The village's sloping topography makes it prone to surface runoff and soil erosion, which can carry essential nutrients and organic matter. This study aims to investigate the selectivity of erosion in each part of the slopes of community rubber plantations in Lau Damak Village, Bahorok District, Langkat Regency.
Background
Lau Damak Village is located in a region with a high potential for soil erosion due to its sloping terrain. Soil erosion can have severe consequences, including the loss of fertile land, decreased agricultural productivity, and increased sedimentation in waterways. Understanding the selectivity of erosion in rubber plantations is crucial for developing effective land management strategies to minimize soil erosion and maintain the sustainability of rubber plantations.
Methodology
This study was conducted from September 2014 to December 2014 through two stages: field activities and laboratory activities. Field activities included land sampling in Lau Damak Village, Bahorok District, Langkat Regency. The analysis was carried out at the Medan BPTP laboratory. This study used the T-test to distinguish the nutritional content in each part of the slope, namely the upper slope, the middle slope, and the lower slope. Observed parameters included N-Total, P-Available, K-DD, C-Org, soil texture, bulk density, and CEC.
Results
The results of this study showed that all N-total, P-Available, K-DD, C-ORG, soil texture, Bulk density, and CEC parameters showed no significant differences. This indicates that land erosion in rubber plantation land in Lau Damak Village, Bahorok District, Langkat Regency, did not show significant selectivity in each part of the slope.
Additional Analysis and Explanation
The results of this study suggest that land erosion in rubber plantations in Lau Damak Village does not show significant selectivity in each part of the slope. Several factors can explain these results, including:
Appropriate Rubber Planting
Rubber planting on the slope with a terraced system can help withstand water flow and minimize erosion. This method allows for the even distribution of water and reduces the risk of soil erosion.
The Existence of Ground Cover Vegetation
Vegetation of land cover such as grass and other ground cover plants can help slow down the flow of water and hold the soil. Ground cover vegetation plays a crucial role in preventing soil erosion by reducing the impact of raindrops and increasing soil stability.
Types of Land
The types of soil in Lau Village are possible to have relatively resistant properties of erosion. This suggests that the soil in the area is less prone to erosion due to its composition and structure.
Recommendation
Although the results of this study indicate that erosion does not show significant selectivity, it is essential to continue making efforts to prevent soil erosion. Some recommendations that can be done include:
Maintaining Ground Cover Vegetation
Ensuring that land cover vegetation is maintained and not disturbed is crucial for preventing soil erosion. Ground cover vegetation helps to slow down the flow of water and hold the soil, reducing the risk of erosion.
Improve the Drainage System
Ensuring the drainage channel is functioning properly to flow rainwater effectively is essential for preventing soil erosion. A well-functioning drainage system can help to reduce the risk of soil erosion by allowing water to flow away from the area.
Applying the Agroforestry System
Planting other plants on the sidelines of rubber plants can increase biodiversity and protect the soil from erosion. Agroforestry systems can help to reduce soil erosion by increasing soil stability and reducing the impact of raindrops.
Conclusion
This study provides important information about the condition of land erosion in rubber plantation land in Lau Damak Village. The results of this study can be used as a basis for developing more effective land management strategies to minimize soil erosion and maintain the sustainability of rubber plantations. By understanding the selectivity of erosion in rubber plantations, we can develop targeted interventions to prevent soil erosion and promote sustainable land use practices.
