Dolomite, Sea Mud, and Several Strain Rhizobia Strains on the Growth of Soybean Plants (Glycine max (L.) Merrill) in Peat Soils

Introduction

Understanding the Importance of Soil Improvement Materials

Soil improvement materials play a crucial role in enhancing the growth and productivity of crops. Among these materials, dolomite and sea mud have been widely used to improve the quality of peat soils. However, the effectiveness of these materials can vary depending on the type of crop, soil type, and application method. This study aims to investigate the effect of dolomite, sea mud, and several strain rhizobia on the growth of soybean plants (Glycine max (L.) Merrill) in peat soils.

Background

Soybean is one of the most widely cultivated crops in the world, and its growth is heavily dependent on the quality of the soil. Peat soils, in particular, are known for their low pH and nutrient-poor properties, which can limit plant growth. Dolomite, a type of limestone, has been used as a soil improvement material to increase the pH and nutrient availability of peat soils. Sea mud, on the other hand, has been used as a repair material to improve soil structure and fertility. However, the effectiveness of these materials can vary depending on the type of crop and soil conditions.

Research Methodology

The study was conducted in two stages. The first stage involved comparing the effects of dolomite and sea mud as soil improvement materials, as well as comparing Rhizobia inoculum from the FP-USU biological soil laboratory collection with Rhizobia inoculum taken from peat soil. The second stage involved trying various doses of sea mud and management as repair material.

Sampling and Treatment

The study began with a sampling of peat soil, measurement of dolomite needs and sea mud, as well as the manufacture of YEM (yerbaceum agar) and inoculum rhizobia. After that, the treatment was applied, followed by planting soybeans and observation of growth parameters.

Research Results

Dolomite Treatment

The results of the first study showed that dolomite treatment as a soil improvement material, as well as its interaction with several rhizobia strains, had a significant influence on the improvement of soil pH, as well as the absorption of N and P by plants. It also had a positive impact on plant height and dry weight of soybean seeds.

Sea Mud Treatment

Conversely, the treatment of sea mud as a repair material showed unfavorable results. Its interaction with some rhizobia strains actually caused a decrease in plant growth, even causing death in soybean plants.

Rhizobia Strains

Treatment with various strains of rhizobia did not have a significant effect on the growth of soybean plants.

Analysis and Implications

Optimal Dose of Sea Mud

The important findings of this study are the optimal dose of sea mud as a soil improvement material, which is 2.5 kg per 14 kg of peat soil or equivalent to 20 tons/hectare, which must be dried for one month before it is applied.

Importance of Selecting Soil Improvement Materials

The results of this study show the importance of selecting the type and dose of soil improvement material to support plant growth. Dolomite is proven to be very effective in improving the quality of peat soils and supporting the growth of soybean plants. Increased pH, as well as the absorption of nutrients such as nitrogen and phosphorus, contributes to better growth.

Concerns about Non-Processed Sea Mud

Conversely, the use of non-processed sea mud can actually be detrimental to plants. This is an important concern for farmers and researchers to better understand the chemical and physical properties of the soil improvement material used, as well as how the interaction between the material and soil microorganisms.

Conclusion

This research provides valuable insights on the management of peat soil and the use of local natural resources in increasing agricultural productivity, especially in soybean plants. It also opens opportunities for further research on the combination and management of other organic materials that can improve soil health and plant growth in agricultural land.

Recommendations

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

Dolomite should be used as a soil improvement material to improve the quality of peat soils and support the growth of soybean plants.

Limitations of the Study

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 soil types and conditions. Secondly, the study only investigated the effect of dolomite and sea mud on the growth of soybean plants, and other crops may have different responses to these materials. Finally, the study did not investigate the long-term effects of using dolomite and sea mud as soil improvement materials.
