Giving Plant Silicate as Amelioran Silicate for Andisol Soil: A Study on the Most Effective and Efficient Material

Introduction

Soil fertility is a crucial factor in plant growth and development. Andisol soil, a type of soil that is rich in volcanic ash, has unique characteristics that make it challenging to manage. One of the ways to improve soil fertility is by adding silicate, a natural material that can increase the activity of soil microorganisms and improve soil structure. This study aims to determine the most effective and efficient plant silicate material in providing silicate to Andisol soil.

Methodology

The study was conducted at the Chemistry Laboratory and the Faculty of Agriculture, University of North Sumatra, Medan. The method used is a complete random design (ran) with the treatment of natural silicate giving consisting of A (seaweed), B (sugar cane), and C (rice straw), where each natural silicate is modified at different pH (4, 7, and 10) and repeated three times, so there are 33 sets of treatment. After being incubated for 45 days, analysis of dissolved silica levels, soil C-organic, P available, and Freundlich adsorption isotherm was conducted.

Results

The results showed that the administration of natural silicate had no significant influence on the availability of soil P, which was caused by the absence of P fertilization. However, the most effective and efficient natural silicate in increasing the C-organic content was silicate derived from seaweed leaves. In addition, rice straw leaves are proven to be the most effective natural silicate in increasing dissolved silica levels, while sugar cane leaves can reduce the rate of adsorption reactions.

Discussion

Giving natural silicate in Andisol soil can contribute to increasing soil fertility. Silicate plays an important role in increasing the activity of soil microorganisms that can improve soil structure and increase the availability of nutrients for plants. In this study, the use of seaweed leaves as a source of silicate showed promising results in increasing soil C-organic. High C-organic functions to increase the capacity of water and soil nutrition, so it is very important for plant growth.

The importance of good soil management and the use of natural materials as amelioran is an ongoing and environmentally friendly step in agriculture. By knowing the most effective type of plant silicate, farmers can be wiser in choosing organic matter to improve the quality of their soil. Further research can be carried out to explore a combination of various natural silicate and its impact on various types of soil and plants.

Conclusion

With the results obtained, it is expected that the use of natural silicate can be an alternative in the management of soil fertility, especially for Andisol soil which has unique characteristics. This is in line with efforts to reduce dependence on synthetic chemicals in agricultural practices and support sustainable agriculture that is more environmentally friendly.

Recommendations

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

  • The use of seaweed leaves as a source of silicate can be a promising alternative in improving soil fertility.
  • Rice straw leaves can be used as a natural silicate to increase dissolved silica levels.
  • Sugar cane leaves can be used to reduce the rate of adsorption reactions.
  • Further research can be carried out to explore a combination of various natural silicate and its impact on various types of soil and plants.

Future Research Directions

This study has provided valuable insights into the use of natural silicate in improving soil fertility. However, there are still many areas that need to be explored. Some of the future research directions include:

  • Investigating the impact of natural silicate on different types of soil and plants.
  • Exploring the combination of various natural silicate and its impact on soil fertility.
  • Developing a more efficient method for producing natural silicate.
  • Conducting field experiments to validate the results of this study.

Limitations of the Study

This study has some limitations that need to be acknowledged. Some of the limitations include:

  • The study was conducted in a controlled laboratory setting, which may not reflect the real-world conditions.
  • The study only used three types of natural silicate, which may not be representative of all types of natural silicate.
  • The study only measured the impact of natural silicate on soil fertility, which may not be the only factor that affects plant growth.

Conclusion

In conclusion, this study has provided valuable insights into the use of natural silicate in improving soil fertility. The results of this study have shown that the use of seaweed leaves as a source of silicate can be a promising alternative in improving soil fertility. Further research is needed to explore the impact of natural silicate on different types of soil and plants, and to develop a more efficient method for producing natural silicate.
