Evaluation Of Land Suitability For Oil Palm (Elaeis Quenensis Jacq). Chocolate (Theobroma Cacao) And Rubber (Havea Brasiliensis) In Belinteng Village, Sei Bingei District, Langkat Regency
Evaluation of Land Suitability for Oil Palm, Cocoa, and Rubber in Belinteng Village, Langkat Regency
Introduction
The evaluation of land suitability for oil palm, cocoa, and rubber cultivation is a crucial aspect of agricultural development in Belinteng Village, Sei Bingei District, Langkat Regency. This study aims to determine the land suitability class for these three important commodity plants in the region. The research was conducted over a period of 18 months, from March 2006 to September 2007, and involved the collection of soil data from two excavation locations, namely PI and P2.
Methodology
The method used in this study was a survey with a detailed end type system, analyzing data using five degrees limiting following the FAO procedure (1976), SYS, et al. (1993), and Modification Sehgal (1996). The soil data was collected from horizon A and B at coordinates 98 ° 28'48 "BT - 98 ° 28'55" BT and 03 ° 26'44 "LU - 03 ° 25'53" LU. The results of the study were analyzed to determine the land suitability class for oil palm, cocoa, and rubber cultivation.
Results
The results of the study showed that the land suitability class for oil palm plants at the PI location was inappropriate (SC), while for rubber and cocoa declared inappropriate (NAW) and not appropriate (NIW). At the location of P2, the land suitability class for oil palm is inappropriate (SCS), rubber is not appropriate (sjest), and cocoa not appropriate (sf).
Additional Analysis and Explanation
The results of this study provide an important picture of the condition of the soil in Belinteng Village and its suitability for the cultivation of oil palm, cocoa, and rubber cultivation. Assessment using the FAO method and modification made allows to examine limiting factors such as slope, drainage, soil texture, and nutritional content, which directly affects plant growth and yield.
The Limiting Factor Found
Several limiting factors were found in the study, including:
*** Slope slope: *** The slope of the steep slope in both research sites shows that the land is vulnerable to erosion, especially during heavy rain. This can cause loss of soil nutrition and reduce plant productivity. *** Drainage: *** Poor drainage conditions at the study site can cause standing water, which can interfere with root growth and increase the risk of plant diseases. *** Soil texture: *** Dominant soil texture of sandy in both research locations shows that the ability of the soil to store water and nutrients is relatively low. ** Nutritional content: *** The results of soil analysis show that the availability of several important nutrients such as nitrogen, phosphorus, and potassium is quite low.
Recommendation
Based on the results of this study, several recommendations can be submitted to increase land eligibility and plant productivity:
** Application of soil conservation techniques: *** Application of soil conservation techniques such as terraces, planting of ground cover plants, and processing soil without sports (no-till) is highly recommended to reduce erosion and increase soil fertility. ** Balanced fertilization: *** Balanced fertilization by considering the nutritional needs of each plant and the results of soil analysis can increase productivity and crop yields. *** Selection of resistant varieties: *** The selection of plant varieties that are resistant to disease and environmental conditions that are less than optimal are very important to increase the success of aquaculture. *** Development of a mixed plant (agroforestry): *** Agroforestry system can help improve the stability of ecosystems, reduce erosion, and increase biodiversity.
Conclusion
This study shows that land in Belinteng Village has limitations in supporting optimal growth of oil palm, cocoa, and rubber. The development and application of appropriate land management strategies, such as soil conservation techniques and balanced fertilization, can help increase land suitability and increase crop productivity. It is important to remember that the selection of proper plants and cultivation strategies that are tailored to environmental conditions are very important to achieve success and sustainability in agricultural activities in the area.
Future Research Directions
Future research should focus on the implementation of the recommendations made in this study, including the application of soil conservation techniques, balanced fertilization, and the selection of resistant varieties. Additionally, research should be conducted to develop a mixed plant (agroforestry) system that can help improve the stability of ecosystems, reduce erosion, and increase biodiversity.
Limitations of the Study
This study has several limitations, including the limited scope of the research and the lack of data on other important factors that can affect plant growth and yield. Future research should aim to address these limitations and provide a more comprehensive understanding of the land suitability for oil palm, cocoa, and rubber cultivation in Belinteng Village.
