The Influence Of Various Types Of Bone Meal On The Chemical Properties Of Soil And Absorption Of P And Corn Growth (zea Mays L.) In Ultisol Soil
The Influence of Various Types of Bone Meal on the Chemical Properties of Soil and Absorption of P and Corn Growth (Zea mays L.) in Ultisol Soil
Introduction
Ultisol soil, characterized by high acidity and low phosphorus availability, poses significant challenges to agricultural productivity. The widespread use of chemical fertilizers, such as SP-36, has been a common solution to address these issues. However, the high environmental impacts and costs associated with these fertilizers have led to a growing interest in exploring alternative, more sustainable options. One such alternative is bone meal, a rich source of calcium and phosphorus that can potentially increase ultisol soil fertility.
Background
Research conducted at the Faculty of Agriculture, University of North Sumatra, aimed to investigate the influence of various types of bone meal on the chemical properties of ultisol soils and the absorption of phosphorus (P) and corn growth (Zea mays L.). This study compared the effects of chicken, fish, and beef bone meal with SP-36 fertilizer as a control. The results of this study provide valuable insights into the potential of bone meal as a sustainable alternative to chemical fertilizers.
The Effect of Bone Meal on Ultisol Soil Fertility and Corn Growth
The results of this study showed that the three types of bone meal, particularly cow bone meal, significantly increased soil pH, organic carbon content, and the availability of phosphorus. Notably, cow bone meal was found to increase corn growth and P-absorption better than SP-36 fertilizer. These findings suggest that bone meal, especially cow bone meal, has great potential as an alternative to SP-36 fertilizer in increasing ultisol soil fertility and corn growth.
Mechanism of the Influence of Bone Meal
The influence of bone meal on ultisol soil fertility and corn growth can be attributed to several mechanisms:
Increasing Soil pH
Bone meal contains calcium carbonate, which can neutralize the acidity of the soil. This increase in soil pH can create a more favorable environment for plant growth, as many plants prefer a slightly acidic to neutral soil pH.
Increasing the Availability of Phosphorus
Phosphorus in bone meal has a higher availability compared to phosphorus in SP-36 fertilizer. This increased availability of phosphorus can lead to improved plant growth and development, as phosphorus is an essential nutrient for plant development.
Increasing Organic Carbon Content
The process of decomposition of bone meal by microorganisms increases soil organic carbon levels, which are useful for improving soil structure and increasing water retention. This can lead to improved soil health and fertility, ultimately benefiting plant growth.
Benefits of Bone Meal
The use of bone meal as a source of organic nutrition has several benefits:
Source of Organic Nutrition
Bone meal is a safe and environmentally friendly organic nutritional source. It is a natural and biodegradable alternative to chemical fertilizers, reducing the risk of environmental pollution.
Increasing Soil Fertility
Bone meal can increase soil pH, availability of nutrition, and soil structure, ultimately leading to improved soil fertility.
Increasing Plant Growth
Bone meal can increase plant growth, nutritional absorption, and crop yields, making it a valuable tool for farmers seeking to improve their yields.
Conclusion
This study demonstrates that bone meal, especially cow bone meal, has great potential as an alternative to SP-36 fertilizer in increasing ultisol soil fertility and corn growth. The use of bone meal as a source of organic nutrition not only has a positive impact on plant growth but also contributes to improving soil quality and agricultural sustainability.
Recommendation
Based on the findings of this study, the following recommendations are made:
- Further research is needed to determine the optimal dose of bone meal required for corn plants in ultisol soils.
- It is essential to examine the long-term effects of bone meal use on soil chemical properties and plant growth.
- Socialization and education of farmers regarding the benefits and ways of using bone meal as an organic fertilizer are necessary to promote its adoption and ensure its effective use.
Future Research Directions
Future research should focus on:
- Investigating the optimal dose of bone meal required for different crops and soil types.
- Examining the long-term effects of bone meal use on soil chemical properties and plant growth.
- Developing guidelines for the use of bone meal as an organic fertilizer, including recommendations for application rates and timing.
Limitations of the Study
This study has several limitations, including:
- The study was conducted on a small scale, and further research is needed to confirm the findings on a larger scale.
- The study only examined the effects of bone meal on ultisol soil fertility and corn growth, and further research is needed to examine its effects on other crops and soil types.
Conclusion
In conclusion, this study demonstrates the potential of bone meal as a sustainable alternative to chemical fertilizers in increasing ultisol soil fertility and corn growth. The use of bone meal as a source of organic nutrition has several benefits, including increasing soil fertility, plant growth, and crop yields. Further research is needed to confirm the findings of this study and to develop guidelines for the use of bone meal as an organic fertilizer.
