Introduction

Ultisol Mancang, a type of soil known for its acidic characteristics and low nutrient content, is often a significant obstacle in farming. However, research conducted in the Glasshouse of the Faculty of Agriculture of USU Medan in 2002 shows the potential for increasing fertility and productivity of corn plants by utilizing organic waste such as sawdust and compost powder. This study aims to investigate the effect of the provision of sawdust and compost ash on soil nutrient chemistry and the production of corn plants.

Methodology

This study employed a factorial experimental design to compare the effects of three levels of sawdust ash (without ash, 6.25g/5kg BTKO, and 12.5g/5kg BTKO) and four levels of compost powder (0g/5kg BTKO, 25g/5kg BTKO, 50g/5kg BTKO, and 75g/5kg BTKO) on soil nutrient chemistry and corn production. The results of this study provide valuable insights into the potential of using organic waste to improve soil quality and plant productivity.

Improved Chemistry of Soil Nutrients

The use of sawdust and compost powder was found to be effective in increasing soil pH and soil organic carbon content, which is essential for maintaining soil fertility and microorganism activity. This is a significant finding, as it suggests that the use of these organic materials can help to mitigate the acidic characteristics of Ultisol Mancang.

Increasing Soil pH and C-Organic

The use of sawdust and compost powder was found to increase soil pH and soil organic carbon content. This is a critical finding, as it suggests that the use of these organic materials can help to improve soil fertility and microorganism activity.

Increased N-Total, P-Available, and K-Tukar

The administration of sawdust and compost powder individually showed a significant effect in increasing total nitrogen levels (N-Total), phosphorial available (P-Available), and potassium exchange (K-Tukar) in the ground. This indicates that both organic materials can act as additional sources of nutrients for corn plants.

Increasing the Production of Corn Plants

The interaction between sawdust ash and compost shows a significant effect on increasing the number of seeds per cob and dry seed weight per cob. This suggests that the combination of the two organic materials is able to produce more abundant corn harvests.

Increasing the Number of Seeds/Cobs and the Weight of Dry Seeds/Cobs

The administration of sawdust and compost powder individually has a positive effect on the vegetative growth of corn plants, such as plant height, cob length, and dry weight of the top of the plant.

Benefits and Implications

This study provides concrete evidence that the use of sawdust and compost can be an effective strategy for increasing the fertility of Ultisol soil and corn productivity. By utilizing these organic waste, farmers can reduce dependence on chemical fertilizers, increase the efficiency of resource use, and carry out more sustainable agricultural practices.

Recommendation

It is necessary to do further research to optimize the dose and optimal combination between sawdust ash and compost to achieve maximum corn yields.
The importance of the application of proper aquaculture techniques, such as organic fertilization and spacing regulation, to support the use of sawdust ash and compost optimally.

Conclusion

This study demonstrates the potential of using sawdust and compost powder to improve soil nutrient chemistry and corn production in Ultisol Mancang. The findings of this study provide valuable insights into the potential of using organic waste to improve soil quality and plant productivity. This is an important step towards encouraging sustainable and environmentally friendly agricultural practices, especially in facing the challenges of land degradation and climate change.

Future Research Directions

Further research is needed to optimize the dose and optimal combination between sawdust ash and compost to achieve maximum corn yields. Additionally, the importance of the application of proper aquaculture techniques, such as organic fertilization and spacing regulation, to support the use of sawdust ash and compost optimally.

Limitations of the Study

This study has several limitations, including the use of a small sample size and the lack of control over environmental factors. Future studies should aim to address these limitations and provide more robust evidence for the effectiveness of using sawdust and compost powder to improve soil nutrient chemistry and corn production.
