Effect of Bokashi and Dolomite Giving on the Availability of Nutrients (N, P, K) Soil and the Absorption of Corn Plants (Zea mays L) in the Ultisol of the Simalingkar Area B

Introduction

Understanding the Challenges of Ultisol Soil

Ultisol is a dominant type of soil in Indonesia, characterized by its acidic reaction and high aluminum content, which can be toxic to plants. This condition leads to phosphorus fixation (P) and other micro-nutrient deficiencies, hindering plant growth and yield. To overcome these challenges, liming and bokashi applications have emerged as effective methods.

The Role of Dolomite and Bokashi in Soil Fertility

Dolomite, a limestone containing calcium and magnesium, can help neutralize soil acidity, while Bokashi, an environmentally friendly organic agent, has been shown to have a significant impact on plant growth and yield. The regular use of Bokashi is expected to improve soil fertility and increase crop productivity.

Methodology

Research Location and Design

This study was conducted in Simalingkar B, Kelurahan Kwala Bekala, from March to July 2005. A random design group (RAK) consisting of two factors with repetition was used. The first factor was the application of Bokashi with five levels: BO (control), B1 (5 tons/ha), B2 (10 tons/ha), B3 (15 tons/ha), and B4 (20 tons/ha). The second factor was the application of dolomite with two levels: DO (control) and D1 (dolomite 3 tons/ha).

Results

The Impact of Bokashi on Soil Fertility

The results showed that the application of Bokashi had a significant effect on the content of soil C-organic, N-total soil content, and the absorption of N and P by plants. Additionally, Bokashi had a very significant influence on the availability of soil P and land exchange. These findings suggest that Bokashi plays a crucial role in improving soil fertility and increasing crop productivity.

The Effect of Dolomite on Soil pH and Nutrient Availability

Dolomite application had a very significant effect on soil pH, as well as a significant effect on K. The interaction between the two treatments also increased soil pH, indicating a beneficial synergy between Bokashi and dolomite administration.

Additional Analysis and Explanation

The Importance of Bokashi in Improving Soil Quality

From the research results, it is clear that Bokashi plays an important role in improving the quality of less fertile soils. Giving Bokashi not only improves soil structure but also increases the availability of vital nutrients for corn plants. The availability of nitrogen (N) and phosphorus (P) is very influential on plant growth, and an increase in soil C-organic creates a better environment for microbial activity that helps the release of nutrients.

The Role of Dolomite in Neutralizing Soil Acidity

Dolomite helps neutralize soil pH, which can reduce aluminum toxicity and facilitate the absorption of nutrients by plant roots. The reduced acidity of the soil also contributes to increasing the availability of other nutrients, including potassium (K). Good exchange in the soil is very important for plant growth, especially in the phase of fruit and seed formation.

The Synergy between Bokashi and Dolomite Administration

The interaction between Bokashi and dolomite administration not only increases soil pH but also creates beneficial synergy in the availability of nutrients. Therefore, the combination of these two ingredients can be considered as an effective solution to overcome the problem of ultisol soil fertility, especially in areas such as Simalingkar B.

Conclusion

Implications for Farmers and Agricultural Sustainability

By knowing the effect of these two treatments, farmers can plan a better and environmentally friendly fertilization strategy, which in turn will increase agricultural productivity and sustainability. The use of Bokashi and dolomite can be a valuable tool for farmers to improve soil fertility and increase crop productivity, ultimately contributing to a more sustainable agricultural system.

Recommendations for Future Research

Future research should focus on exploring the long-term effects of Bokashi and dolomite administration on soil fertility and crop productivity. Additionally, studies should investigate the optimal application rates and combinations of these two ingredients to maximize their benefits.

Conclusion

In conclusion, this study highlights the importance of Bokashi and dolomite in improving soil fertility and increasing crop productivity. The findings of this research have significant implications for farmers and agricultural sustainability, and further research is needed to fully understand the benefits and limitations of these two ingredients.
