Improvement of the Physical Properties of Paddy Soil through the Provision of Organic Matter in Watermelon Planting Land

Abstract

Soil physical properties play a crucial role in plant growth, and the provision of organic matter is a vital aspect of improving these properties. This research aims to determine the changes in soil physical properties due to the provision of organic matter, such as rice straw, sheep dung, and petroganic fertilizer, on paddy fields planted with watermelon in Air Hitam Village, Batubara District, North Sumatra Province. The study was conducted from April to June 2014, and the experimental design used was a random block design not factorial with four types of organic material (without organic matter (control), rice straw (5 tons/ha), sheep dung (2.5 tons/ha), petroganic organic fertilizer, and straw mulch (0.5 tons/ha)) with three replications.

Introduction

Soil physical properties, such as soil texture, bulk density, and water content, are essential for plant growth. The provision of organic matter is a common practice in agriculture to improve soil physical properties. However, the effectiveness of different types of organic matter in improving soil physical properties is still unclear. This study aims to investigate the changes in soil physical properties due to the provision of organic matter, such as rice straw, sheep dung, and petroganic fertilizer, on paddy fields planted with watermelon.

Research Methodology

The study was conducted in Air Hitam Village, Batubara District, North Sumatra Province, with a height of + 18 meters above sea level. The experimental design used was a random block design not factorial with four types of organic material (without organic matter (control), rice straw (5 tons/ha), sheep dung (2.5 tons/ha), petroganic organic fertilizer, and straw mulch (0.5 tons/ha)) with three replications. The study took place from April to June 2014.

Research Result

The results showed that the provision of rice straw on paddy fields did not increase the content of soil C-organic, bulk density, soil water content, and soil texture. Increased soil C-organic content in rice straw treatment is only 0.5% compared to control treatment. However, the application of sheep as much as 2.5 tons/ha significantly increases the content of C-organic soil, decreases the density of soil bulk, and increases total pore space compared to other treatments. The ground water content in the treatment of sheep dung is higher than other treatments, although statistically it is not significantly different from the water content in the control treatment.

Discussion

The results of this study indicate that the provision of organic matter can improve soil physical properties. However, the effectiveness of different types of organic matter varies. The application of sheep dung as much as 2.5 tons/ha significantly increases the content of C-organic soil, decreases the density of soil bulk, and increases total pore space compared to other treatments. This suggests that sheep dung is a more effective type of organic matter in improving soil physical properties.

Additional Analysis and Explanation

The provision of organic matter in rice fields is very important because it can affect various soil physical properties that play a role in plant growth. Rice straw, although it is an organic material, apparently does not have a significant impact on improving soil physical properties as expected. This may be caused by the composition and quality of straw material that is less than optimal in increasing soil fertility.

Conversely, sheep dirt shows better results. This animal waste is rich in nutrients and can increase the activity of microorganisms in the soil, which in turn increases the process of decomposition of other organic materials. With the increase in C-organic content, the soil becomes more loose, improving the ability of the soil in storing water, and providing space for plant roots to grow well.

The use of petroganic fertilizer can also be considered as an alternative in managing soil fertility. This fertilizer, which is a combination of organic and inorganic materials, can have a synergistic effect in improving the physical and chemical properties of the soil, thus supporting more optimal watermelon growth.

Conclusion

The selection of appropriate types of organic matter is very influential on the success of watermelon cultivation in paddy fields. The use of sheep dung as the main organic material can be a recommendation to improve the quality of soil and watermelon harvest in the future. Further research on the use of a combination of various organic materials also needs to be done to get better and optimal results for sustainable agriculture.

Recommendation

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

The use of sheep dung as the main organic material can be a recommendation to improve the quality of soil and watermelon harvest in the future.
Further research on the use of a combination of various organic materials needs to be done to get better and optimal results for sustainable agriculture.
The provision of organic matter in rice fields is very important because it can affect various soil physical properties that play a role in plant growth.
The use of petroganic fertilizer can also be considered as an alternative in managing soil fertility.

Limitation

This study has some limitations that need to be addressed in future research. The study was conducted in a specific location, and the results may not be generalizable to other locations. Additionally, the study only investigated the effects of different types of organic matter on soil physical properties, and did not investigate the effects on other soil properties, such as soil chemical properties.

Future Research

Future research should focus on investigating the effects of different types of organic matter on other soil properties, such as soil chemical properties. Additionally, research should be conducted to investigate the effects of different combinations of organic materials on soil physical properties. This will provide a more comprehensive understanding of the effects of organic matter on soil properties and will help to develop more effective strategies for improving soil fertility and plant growth.
Frequently Asked Questions (FAQs) about Improvement of Physical Properties of Paddy Soil through the Provision of Organic Matter in Watermelon Planting Land
