## 1. Introduction

Soil is a critical component of ecosystems, influencing not only plant growth but also water quality, climate regulation, and biodiversity. Understanding soil properties is key for effective land management and sustainable agricultural practices. This report presents findings from a comprehensive soil analysis of various land use types, including grassland, water bodies, rubber plantations, palm oil plantations, and dry lands. 

## 2. Materials and Methods

Soil samples were collected from five distinct land use types in the study area. Each sample was analyzed for a variety of soil properties, including texture (sand, clay, silt), pH, aluminum (Al3+), hydrogen ions (H+), cation exchange capacity (CEC), available phosphorus (Av.P), total nitrogen (TN), potassium (K), sodium (Na), magnesium (Mg), calcium (Ca), organic carbon (OC), effective cation exchange capacity (ECEC), and base saturation (BS).

### 3.1 Soil Properties of the Study Area

The data indicates a significant variation in soil properties across different land uses, which can be attributed to vegetation cover, land management practices, and natural factors. 

## 4. Discussion

### 4.1 Interpretation of Soil Characteristics

- **Texture**: The grassland and dry land areas exhibited higher sand percentages (80.083% and 87.589%, respectively), implying well-drained soil. In contrast, the water area had the highest clay content (75.02%), indicating potential drainage issues.
- **pH Levels**: The pH of the samples ranged from 5.30 to 6.35, highlighting that most soils are mildly acidic to neutral, which is generally favorable for plant growth.
- **Cation Exchange Capacity (CEC)**: CEC values varied slightly across land use types, with rubber and palm oil having similar CEC values around 6.69 and 6.34 cmol/kg, indicating moderate nutrient holding capacity.
- **Organic Carbon (OC)**: Organic carbon content is crucial for soil fertility. The organic matter levels in the water area and rubber cultivation were relatively lower compared to other land uses.
- **Base Saturation (BS)**: BS values were predominantly high (>80%), suggesting effective nutrient availability across the study area.

### 4.2 Implications for Land Use

The results from this analysis can aid in land management strategies. For example, areas with higher clay content may benefit from drainage improvements, while sandy soils may require amendments to retain moisture. 

Furthermore, sustainable practices aimed at enhancing organic carbon content should be implemented, particularly in water and rubber areas, where lower values were noted.

## 5. Conclusion

The soil analysis indicates distinct variations in soil properties across different land use types within the study area. Understanding these variations is essential for creating tailored land management and agricultural strategies that enhance productivity while maintaining soil health.

_(All parameters are expressed in standard units. Sand, clay and silt are expressed in percentage (%). pH is dimensionless; Al³⁺, H⁺, K, Na, Mg, and Ca are in cmol/kg; Av.P and TN in mg/kg and percentage (%); OC is in percentage; ECEC is in cmol/kg; BS is in percentage (%).)_

### Analysis of Results

1. **Soil Texture**: 
   - The grassland (G) and dryland (D) have high sand content, indicating sandy soils with good drainage. The water land use (W) shows high clay content, which may retain water well but could lead to drainage issues. 
   
2. **pH Levels**: 
   - The pH of the samples ranges from 5.30 (W) to 6.35 (D), suggesting the soils are mildly acidic to neutral. This pH level can be beneficial for the availability of nutrients for various crops.

3. **Cation Exchange Capacity (CEC)**: 
   - The CEC values indicate that the soil has a moderate capacity to hold cations (nutrients). Values range from 6.325 cmol/kg (G) to 6.692 cmol/kg (R), pointing towards satisfactory nutrient retention capabilities.

4. **Nutrient Availability**: 
   - The available phosphorus (Av.P) and total nitrogen (TN) contents are essential for plant growth. The highest Av.P is found in dryland (17.25 mg/kg), which suggests that this land use is most suitable for crops requiring higher phosphorus levels.

5. **Organic Carbon (OC)**: 
   - The OC values range from 0.962% (W) to 1.330% (D), indicating that organic matter content in these soils is relatively low to moderate, which can affect soil fertility.

6. **Base Saturation (BS)**: 
   - BS ranges from 83.05% (W) to 87.84% (P), which reveals that most of the cation exchange capacity is occupied by basic cations, implying good soil health and fertility potential.

## Discussion

The analysis indicates that different land uses significantly impact soil properties. Grasslands and drylands are more conducive to supporting crops with their higher sand content and good drainage, while water land use has high clay content, which could potentially merit management practices to enhance drainage. 

Each of the land-use types shows potential for agricultural use, albeit with considerations of pH, nutrient levels, and organic content. Tailored management strategies should be developed for each land use to enhance soil health, mitigate nutrient leaching, and increase productivity sustainably.

## Recommendations

1. **Soil Amendments**: Implement the application of organic fertilizers, particularly in areas with lower OC and TN.
2. **Irrigation Management**: Consider improved drainage methods in water-dominated areas to prevent waterlogging.
3. **Crop Selection**: Choose crops based on specific soil nutrient availability and pH levels for optimal growth.
4. **Regular Monitoring**: Conduct periodic soil testing to monitor changes in soil properties and adjust management practices accordingly.

## Conclusion 

This report provides a comprehensive analysis of soil properties across different land uses in the study area. Understanding these properties will aid land use planning, agricultural practices, and sustainable soil management to enhance productivity and soil health.
