Study of the Physical and Chemical Properties of the Soil Relationship with Oil Palm Production (Elaeis guineensis, Jacq) in the Kwala Sawit PTPN II Garden

Introduction

The Kwala Sawit PTPN II garden is a significant oil palm production site, dominated by Typic Paleudult land. Despite its suitable land class (S3), the garden's oil palm production has not reached its expected potential. This phenomenon raises important questions about the relationship between the physical and chemical properties of the soil and oil palm production. To address this issue, researchers conducted an in-depth study to examine the linkages between these factors.

Background

The Kwala Sawit PTPN II garden is characterized by a unique soil type, Typic Paleudult, which has a distinct carbon content (C) profile. The upper and lower layers of the soil have different C content levels, while the nitrogen (N) and phosphorus (P) content is relatively low. The soil pH tends to be acidic, which can inhibit oil palm growth. Despite the suitable land class, the garden's oil palm production has not achieved its expected potential.

Methodology

This study examined various parameters, including soil pH, C/N, P available, CTK, base saturation, soil texture, bulk density, density particles, and total pore space. The researchers aimed to identify the physical and chemical factors that affect oil palm production in the garden.

Results

The study revealed several key findings:

Soil pH: The soil pH in the garden is classified as very low to low (4.2-5.5), indicating a high level of acidity that can inhibit oil palm growth.
C/N ratio: The C/N ratio is classified as very low to moderate (0.17–9.4), indicating limited nitrogen availability, which can inhibit plant growth.
P content: Although the P content is classified as sufficient (18.25-56.68 ppm), uneven P content in various locations can affect plant growth.
Cation Ca+2 and Mg+2: The content of Ca+2 is classified as very low to low (1,22–4.88 me/100g), while Mg+2 is classified as high to very high (0.84-3.35 me/100g). The significant difference in the content of these cations can affect nutrient balance in the soil and plant growth.
KTK and base saturation: The KTK content is classified as (12.50–23.60 me/100g), and base saturation is very low to low (10.70–69.03 %). Low base saturation shows the ability of the soil in holding limited nutrients, which can affect the availability of nutrients for oil palm.
Soil texture: The soil texture is dominated by high clay fractions, with bulk density (BD) and relatively high density (PD) particles. This condition can inhibit root growth and water and nutritional absorption, which in turn can reduce bunch production.

Discussion

The study shows that several physical and chemical factors of the soil in the Kwala Sawit garden are interrelated and significantly affect oil palm production. The key factors that determine the production of bunches per principal are C/N, P available, Na exchange, bulk density, and total pore space.

Conclusion

Based on the findings of this study, the production of bunches per principal of oil palm in Afdeling III, PTPN II Kwala Sawit Gardens, is below the average production based on land class standards. The realization is only 6.1–6.5 bunches per principal, far below the expected potential. This study provides a better understanding of the constraints encountered in increasing oil palm production in the PTPN II Kwala Sawit Plantation. The results of this study can be a reference in formulating more effective soil management strategies, such as appropriate fertilization, drainage improvement, and appropriate soil treatment, to increase oil palm production and achieve optimal land potential.

Recommendations

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

Soil management: Implementing effective soil management strategies, such as appropriate fertilization, drainage improvement, and soil treatment, can help increase oil palm production and achieve optimal land potential.
Fertilization: Fertilization should be tailored to the specific needs of the oil palm plants, taking into account the soil's physical and chemical properties.
Drainage improvement: Improving drainage in the garden can help reduce waterlogging and increase soil aeration, which can improve oil palm growth.
Soil treatment: Soil treatment, such as liming or acidification, may be necessary to adjust the soil pH and improve nutrient availability.

Future Research Directions

This study provides a foundation for further research on the relationship between the physical and chemical properties of the soil and oil palm production. Future studies can focus on:

Soil management strategies: Investigating the effectiveness of different soil management strategies, such as fertilization, drainage improvement, and soil treatment, on oil palm production.
Soil properties: Examining the relationship between soil properties, such as pH, C/N ratio, and nutrient availability, and oil palm production.
Oil palm varieties: Investigating the performance of different oil palm varieties in response to different soil conditions.

Limitations of the Study

This study has several limitations:

Sample size: The sample size of this study was limited to a single garden, which may not be representative of other oil palm production sites.
Soil properties: The study only examined a limited number of soil properties, which may not be representative of the full range of soil properties that affect oil palm production.
Oil palm varieties: The study only examined a single oil palm variety, which may not be representative of other varieties.

Conclusion

In conclusion, this study provides a better understanding of the constraints encountered in increasing oil palm production in the PTPN II Kwala Sawit Plantation. The results of this study can be a reference in formulating more effective soil management strategies to increase oil palm production and achieve optimal land potential.
