The Application of Chocolate Algae Compost (Sargassum Polycystum) is Enriched with Various Combinations of N, P, and K Fertilizer Dosage on the Chemical Properties of Inseptisol and Corn Plants

Introduction

The use of compost in agriculture has become increasingly popular in recent years due to its potential to improve soil fertility and increase crop yields. One type of compost that has gained attention is the chocolate algae compost (Sargassum polycystum), which is a type of seaweed that is rich in nutrients. This study investigates the effectiveness of the compost of chocolate algae (Sargassum polycystum) which is enriched with various doses of N, P, and K fertilizer on the chemical properties of insepticol soils and the growth of corn plants.

Materials and Methods

This study was conducted during June to October 2013 with a non-factorial random block design, involving 7 treatments and 4 replications. The treatment consists of:

*** P0: ** Compost Chocolate algae without additional fertilizer. *** P1, P2, P3, P4, P5, and P6: ** Chocolate algae compost is enriched with various combinations of urea, SP36, and KCL fertilizer dosages given at the beginning of the vegetative period and the end of the vegetative period.

The measured parameters include:

Soil pH (H2O): This is an important factor in determining the fertility of the soil. A pH level that is too high or too low can affect the availability of nutrients for plants.
Organic carbon content (C-organic): This is an important indicator of soil fertility and can affect the growth of plants.
Total nitrogen content (n-total): Nitrogen is an essential nutrient for plant growth, and its availability can affect the growth of plants.
Available phosphorus (P-AVAILABLE): Phosphorus is an essential nutrient for plant growth, and its availability can affect the growth of plants.
Potassium exchange (k-exchange): Potassium is an essential nutrient for plant growth, and its availability can affect the growth of plants.
Plant height: This is an important indicator of plant growth and can affect the yield of crops.
Dry weight of roots and canopy: This is an important indicator of plant growth and can affect the yield of crops.
Weight of corn cobs along with its duplicate: This is an important indicator of crop yield and can affect the productivity of farms.

Results

The results showed that chocolate algae compost that was enriched with NPK fertilizer significantly affected the soil pH (H2O), K-exchange, plant height, and weight of corn cobs and their olfactory. Treatment ** P5 ** (brown algae compost is enriched with 4G urea, SP36 2G, and 0.5G KCl at the beginning of the vegetative period, and 2G urea, SP36 2G, and 1G KCl at the end of the vegetative period) gives the best results in terms of cob weight corn along with its duplicity and dry weight of corn plants.

Discussion

The results of this study show that the application of chocolate algae compost (Sargassum polycystum) which is enriched with NPK fertilizer can be an effective way to improve soil fertility and increase crop yields. The treatment P5 shows that the controlling NPK fertilizer that is controlled at the beginning and end of the vegetative period can increase the production of corn biomass.

Impact on Soil Chemical Properties

The results of this study show that chocolate algae compost that is enriched with NPK fertilizer is proven to be able to increase soil pH and increase the availability of potassium in the soil. This shows that this compost can help increase soil fertility and create more optimal conditions for plant growth.

Impact on the Growth of Corn Plants

The results of this study show that the compost of chocolate algae enriched by NPK fertilizer has a positive effect on the growth of corn plants, seen from an increase in plant height and dry weight.

Optimization of Fertilizer Dose

It is important to choose the right dose of fertilizer to get maximum results. P5 treatment shows that the controlling NPK fertilizer that is controlled at the beginning and end of the vegetative period can increase the production of corn biomass.

Conclusion and Recommendations

The application of chocolate algae compost (Sargassum polycystum) which is enriched with NPK fertilizer can be an alternative solution in increasing soil fertility and productivity of corn plants. P5 treatment shows good potential in increasing crop yields. Further research is needed to optimize the dose of fertilizer and understand the mechanism of action of chocolate algae compost in increasing plant growth.

Future Research Directions

Further research is needed to optimize the dose of fertilizer and understand the mechanism of action of chocolate algae compost in increasing plant growth. Additionally, the effects of chocolate algae compost on other crops and soil types should be investigated.

Limitations of the Study

This study was conducted in a controlled environment, and the results may not be applicable to other conditions. Additionally, the study only investigated the effects of chocolate algae compost on corn plants, and the effects on other crops should be investigated.

Conclusion

In conclusion, the application of chocolate algae compost (Sargassum polycystum) which is enriched with NPK fertilizer can be an effective way to improve soil fertility and increase crop yields. The treatment P5 shows that the controlling NPK fertilizer that is controlled at the beginning and end of the vegetative period can increase the production of corn biomass. Further research is needed to optimize the dose of fertilizer and understand the mechanism of action of chocolate algae compost in increasing plant growth.
