Study Of The Physical Properties Of Paddy Land In Sunggal District, Deli Serdang Regency

Introduction

The study of physical properties of paddy land in Sunggal District, Deli Serdang Regency, is a crucial aspect of understanding the factors that influence agricultural productivity in the region. Paddy land, also known as rice fields, is a vital component of the agricultural sector in Indonesia, and its physical properties play a significant role in determining soil fertility and rice productivity. This study aims to investigate the physical properties of paddy soil in Sunggal District, Deli Serdang Regency, with a focus on bulk density, permeability, soil texture, and total pore space.

Methodology

The study employed a stratified random sampling survey method to collect data from 17 samples of paddy soil in Sunggal District, Deli Serdang Regency. The samples were taken from two types of rice fields: rain-fed rice fields and irrigation rice fields. The parameters analyzed in this study include bulk density using the ring sample method, permeability, soil texture with the bouyoucos hydrometer method, and total pore space. The results of the analysis were then compared to determine the physical properties of paddy soil in the study area.

Results

The results of the analysis showed that the bulk density and permeability of rice fields in Sunggal District, Deli Serdang Regency, are classified as medium. This indicates that the soil has a density that allows the growth of plant roots well, but may not be optimal for water and nutrient availability. The soil texture was categorized as clay, which implies that the soil has a good mixture between fine and rough particles, allowing it to withstand humidity well while providing sufficient air space for the roots. The total pore space was also included in the good category, indicating that the soil has the ability to store water and provide oxygen needed by plant roots.

Discussion

Soil physical properties, such as bulk density, permeability, texture, and total pore space, are crucial in determining soil fertility and rice productivity. Bulk density, which is classified as medium, indicates that the soil has a density that allows the growth of plant roots well. However, density that is too high can prevent root growth and reduce the availability of water and nutrients. Permeability, which is also classified as medium, plays an important role in determining how fast water can seep into the ground. Soil with good permeability can avoid standing water that can damage plants.

The classification of soil texture as clay implies that the soil has a good mixture between fine and rough particles, allowing it to withstand humidity well while providing sufficient air space for the roots. A good pore space shows that the soil has the ability to store water and provide oxygen needed by plant roots. This is very important for rice plants that require stable water supply.

Research Implications

The results of this study provide useful insights for farmers and land managers in Sunggal District in optimizing their agricultural practices. With a better understanding of the nature of soil physics, farmers can implement more effective soil management techniques, including proper land management, the selection of appropriate rice types, and efficient irrigation regulation. This is expected to increase crop yields and agricultural sustainability in the area.

Conclusion

Overall, this study made an important contribution to the development of agriculture in Deli Serdang Regency, especially in increasing understanding of the physical nature of paddy soils related to agricultural productivity. The study highlights the importance of soil physical properties in determining soil fertility and rice productivity, and provides valuable insights for farmers and land managers in optimizing their agricultural practices.
