The Effect of Giving Straw Compost and SP-36 Fertilizer in Sulfate Soil on Changes in Chemical Properties and Growth and Rice Production

Introduction

Rice (Oryza sativa L.) is one of the main sources of food that is very important for the community. In an effort to increase rice production, one of the challenges faced is the chemical properties of the soil, especially in acid sulfate soils. This study aims to explore the effect of giving straw compost and SP-36 phosphorus fertilizer on the chemical properties of soil, growth, and rice production.

Background

Rice is a staple food for more than half of the world's population, and its production is crucial for food security. However, rice production is often hampered by the chemical properties of the soil, particularly in acid sulfate soils. These soils are characterized by low pH levels, high levels of aluminum and iron, and low levels of organic matter, making it difficult for plants to grow. In addition, acid sulfate soils are often prone to heavy metal toxicity, which can be detrimental to plant growth.

Methodology

This study uses factorial random block designs consisting of two main factors. The first factor is the compost of rice straw compost (J) with four levels of treatment: J0 = 0 tons ha-1 (without giving straw), j1 = 10 tons ha-1, j2 = 20 tons ha-1, and j3 = 30 tons ha-1. The second factor is the treatment of phosphorus fertilizer (P) which also has four levels: P0 = 0 kg sp-36 ha-1, p1 = half dose, p2 = full dose, and p3 = one and a half dose.

Results

The results showed that the compost of rice straw compost had a significant influence on the increase in C-organic, decreased Fe2+, total seed number, and root dry weight. This compost increases soil fertility by increasing organic matter content that is important for plant growth. In addition, low Fe2+ levels can prevent heavy metal toxicity which is often a problem in acid sulfate soils.

On the other hand, the application of SP-36 fertilizer also has a positive effect by increasing the total number of seeds. This shows the importance of the availability of sufficient phosphorus to support the process of photosynthesis and plant growth. The combination of straw compost and SP-36 fertilizer turns out to give better results, with a significant increase in total total seeds.

Discussion

The results of this study suggest that the combination of straw compost and SP-36 fertilizer is effective in improving soil chemical properties and rice growth and production. Appropriate soil management strategies by utilizing local organic materials such as rice straw and the use of appropriate chemical fertilizers can help increase rice productivity, especially on land with less supportive soil properties. This discovery has the potential to be adopted in sustainable agricultural practices, especially in areas with sour sulfate land, to support food security.

Conclusion

With a better understanding of land management and the use of appropriate agricultural inputs, farmers are expected to increase crop yields and maintain long-term soil fertility. The use of straw compost and SP-36 fertilizer can be a valuable tool in achieving this goal. By adopting sustainable agricultural practices, farmers can not only increase their crop yields but also contribute to the conservation of natural resources and the protection of the environment.

Recommendations

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

  • The use of straw compost and SP-36 fertilizer should be promoted as a sustainable agricultural practice in areas with acid sulfate soils.
  • Farmers should be educated on the importance of soil management and the use of appropriate agricultural inputs to improve soil fertility and crop yields.
  • Further research should be conducted to explore the long-term effects of using straw compost and SP-36 fertilizer on soil fertility and crop yields.

Limitations

This study has several limitations that should be noted. Firstly, the study was conducted in a controlled environment, and the results may not be generalizable to other areas with different soil types and conditions. Secondly, the study only examined the effects of straw compost and SP-36 fertilizer on soil chemical properties and rice growth and production, and did not examine other potential benefits of using these inputs, such as improved soil structure and increased biodiversity.

Future Research Directions

Future research should focus on exploring the long-term effects of using straw compost and SP-36 fertilizer on soil fertility and crop yields. Additionally, research should be conducted to examine the effects of using these inputs on other crops and soil types. Furthermore, research should be conducted to explore the economic and social benefits of using straw compost and SP-36 fertilizer, such as increased crop yields and improved food security.
