Introduction

The study of salinity levels and land texture on paddy fields in Percut Village, Percut Sei Tuan District, Deli Serdang Regency, is a crucial aspect of understanding the condition of agricultural land in the region. The aim of this research is to obtain data related to the level of soil salinity and its distribution, which is essential for farmers and land managers to make informed decisions about land management. This study was conducted from May to September 2019, using a free grid survey method with a sampling density of one sample for every 25 hectares of land.

Methodology

The parameters measured in this study include soil salinity, which was measured using an electrical conductivity (DHL) meter, and soil texture, which was measured using the hydrometer method. The results of the analysis were categorized into three criteria based on the standards set by Dobberman and Fairhurst (2000). These criteria are low criteria with an area of 128 hectares (28%), moderate criteria with an area of 147 hectares (33%), and high criteria with an area of 175 hectares (39%).

Results and Discussion

The results of the study show that the spread of soil salinity in Percut Village paddy fields can be categorized into three criteria based on the standards set by Dobberman and Fairhurst (2000). The high level of salinity in most of the paddy fields in Percut Village is a concern, as it can potentially damage plants, reduce crop yields, and change the physical and chemical properties of the soil. Therefore, a good understanding of the level of salinity is very important for farmers and land managers to make appropriate decisions in land management.

The measurement of soil texture in the paddy fields shows that the dominance of the sand fraction makes the land in this region have sandy clay and sandy sand. Soil texture dominated by sand fractions can also affect the ability of the soil in storing water and nutrients. Sand-textured soil tends to have a low water retention capacity, making it more susceptible to drought. Therefore, farmers in this village are advised to consider water conservation methods and the selection of plant varieties that are more resistant to existing soil conditions.

Importance of Systematic Survey Method

This research also highlights the importance of a systematic survey method to obtain accurate and relevant data. The results of this study are expected to be a reference for the authorities in formulating strategic policies and actions to improve the quality of agricultural land in Deli Serdang Regency. By understanding the level of salinity and texture of the land, it is hoped that farmers and land managers can take the prevention and improvement measures needed to achieve optimal and sustainable agricultural products in the future.

Conclusion

In conclusion, the study of salinity levels and land texture on paddy fields in Percut Village, Percut Sei Tuan District, Deli Serdang Regency, is a crucial aspect of understanding the condition of agricultural land in the region. The results of this study show that most of the paddy fields in Percut Village have a relatively high level of salinity, with a significant area. Therefore, farmers need to apply better land management techniques, such as proper irrigation, the use of organic fertilizer, and plant rotation to maintain soil quality.

Recommendations

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

Farmers in Percut Village should consider water conservation methods and the selection of plant varieties that are more resistant to existing soil conditions.
The authorities should formulate strategic policies and actions to improve the quality of agricultural land in Deli Serdang Regency.
Further research should be conducted to investigate the effects of salinity and soil texture on crop yields and plant growth.

Limitations of the Study

This study has several limitations, including:

The study was conducted in a limited area, and the results may not be generalizable to other areas.
The study only measured soil salinity and texture, and did not consider other factors that may affect crop yields and plant growth.
The study was conducted over a short period of time, and the results may not reflect long-term trends.

Future Research Directions

Future research should focus on investigating the effects of salinity and soil texture on crop yields and plant growth. Additionally, research should be conducted to develop strategies for improving soil quality and reducing the negative impacts of salinity on agricultural productivity.
