The Effect of Giving Liquid Compost of Brown Algae (Sargassum Polycystum) and Fertilizers N, P, K on the Chemical Properties of Ultisol Soils and Onion Production

Introduction

Soil quality plays a crucial role in plant productivity, and ultisol soils, known for their low pH levels and limited fertility, require appropriate management to increase plant growth. The use of liquid compost from brown algae (Sargassum polycystum) is an environmentally friendly alternative in improving soil quality. This study aims to understand the effect of giving liquid compost from brown algae and fertilizers N, P, K on the chemical properties of ultisol soils and the production of shallots.

Background

Ultisol soils are characterized by their low pH levels and limited fertility, making them challenging to cultivate. The use of liquid compost from brown algae is an environmentally friendly alternative in improving soil quality. Brown algae (Sargassum polycystum) is rich in minerals and organic compounds that can improve soil structure and increase favorable microbial activity. Fertilizers N, P, K have an important role in plant growth, with nitrogen (N) functioning for vegetative growth, phosphorus (P) being important for root development, and potassium (K) being needed to increase plant resistance to disease.

Methodology

This study was conducted from June to October 2017 using a random design of non-factorial groups, involving seven treatments that were repeated four times. The treatment tested included:

P0: Control
P1: Liquid compost 20 cc (3 times giving) without being enriched
P2: Liquid compost 20 cc (3 times administration + 2 g urea + 5 g SP36 + 0.5 g KCl)
P3: Liquid compost 20 cc (3 times administration + 1 g urea + 2.5 g sp36 + 0.25 g KCl)
P4: Liquid compost 20 cc (6 times giving) without being enriched
P5: Liquid compost 20 cc (6 times administration + 2 g urea + 5 g SP36 + 0.5 g KCl)
P6: Liquid compost 20 cc (6 times administration + 1 g urea + 2.5 g sp36 + 0.25 g KCl)

The parameters measured in this study include the dry weight of the tubers, the dry weight of the canopy, the pH of H2O, C-organic, N-Total, P-Available, and K-DD.

Results

The results showed that the use of liquid compost of chocolate algae and N, P, K fertilizer can increase the pH of H2O, K-DD, P available, C-organic, and dry weight of tubers and canopy. The treatment that gives the best results is P2, where the use of 20 cc liquid compost is accompanied by N, P, K fertilizer provides a significant increase in the dry weight of the tubers, the dry weight of the canopy, and the availability of P in the soil.

Analysis of the Effect of Liquid Compost and Fertilizer on Ultisol Soil

Ultisol soil requires appropriate management to increase plant productivity. The use of liquid compost from brown algae is an environmentally friendly alternative in improving soil quality. Chocolate algae (Sargassum polycystum) is rich in minerals and organic compounds that can improve soil structure and increase favorable microbial activity.

Fertilizers N, P, K have an important role in plant growth. Nitrogen (N) functions for vegetative growth, phosphorus (P) is important for root development, and potassium (K) is needed to increase plant resistance to disease. With a combination of liquid fertilizer and compost, not only nutrients are added, but also to improve the quality of the soil as a whole.

Provision of liquid compost enriched with N, P, K fertilizer in P2 treatment gives optimal results. This shows the importance of the right formulation in the use of fertilizers and liquid compost to achieve the ideal balance in providing nutrients for plants. In addition, increasing soil chemical properties such as pH and nutrient availability can have a positive impact on the growth and production of shallots.

Conclusion

This study confirms that the right combination of fertilization, especially with the addition of liquid compost from brown algae, can be an effective strategy in improving the chemical properties of ultisol soils and the productivity of shallots. This provides a basis for further research in the use of organic materials for sustainable agriculture and increases the production of plants in land with less than optimal soil quality.

Recommendations

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

The use of liquid compost from brown algae can be an effective strategy in improving the chemical properties of ultisol soils and the productivity of shallots.
The right combination of fertilization, especially with the addition of liquid compost from brown algae, can be an effective strategy in improving the chemical properties of ultisol soils and the productivity of shallots.
Further research is needed to explore the use of organic materials for sustainable agriculture and to increase the production of plants in land with less than optimal soil quality.

Limitations

This study has several limitations, including:

The study was conducted in a controlled environment, and the results may not be applicable to other environments.
The study only measured the effect of liquid compost and fertilizers on ultisol soils and shallot production, and did not explore other potential benefits of using liquid compost and fertilizers.
The study only used a limited number of treatments, and further research is needed to explore the effects of different combinations of liquid compost and fertilizers.

Future Research Directions

Based on the findings of this study, the following future research directions are suggested:

Exploring the use of liquid compost from brown algae in other types of soils and crops.
Investigating the effects of different combinations of liquid compost and fertilizers on ultisol soils and shallot production.
