Increasing the Availability of Phosphorus from Natural Phosphate Fertilizer through the Administration of Acid Compounds in Ultisol Gebang

Introduction

Phosphorus (P) is one of the essential nutrients required by plants for optimal growth and development. However, the availability of phosphorus in soil is often limited, especially in ultisol soils which have low fertility levels. The use of natural phosphate fertilizers is a promising approach to increase phosphorus availability in soil. This study aims to explore the increase in the availability of phosphorus from natural phosphate fertilizer through the use of acid compounds in ultisol soils in the gebang.

Research Methodology

The research activity was carried out in the Laboratory of Land and Greenhouse Chemistry, Faculty of Agriculture, University of North Sumatra (USU) in Medan. A random design of non-factorial groups with 17 treatments was adopted, using four types of acid compounds: 2% lactic acid, 2% citric acid, 2% sulfuric acid, and 2% clanda acid. In addition, three types of natural phosphate fertilizers were used: without natural phosphate, Chman Island RPC, and RPM from Egypt. The treatment was applied simultaneously 10 days before the planting process.

Parameters Measured

The parameters measured in this study include soil pH, the availability of P, plant height, canopy dry weight, root dry weight, and plant absorption. The results showed that the administration of acid compounds can increase soil pH, availability of P, plant height, canopy dry weight, root dry weight, and plant absorption.

Results and Discussion

The results obtained show that the administration of acid compounds can increase the availability of phosphorus in soil. Of the three natural phosphate fertilizers tested, the results obtained show that fertilizer from Egypt RP produces better performance. In addition, sulfuric acid is proven to be the most effective acid compound in dissolving natural phosphate compared to other acid compounds.

The use of natural phosphate from Egypt RP as a source of nutrition shows better results compared to other sources. This may be caused by the phosphorus content in the fertilizer which is more easily dissolved in ultisol soil conditions. The success in this study shows that acid compounds not only function as a regulator of soil pH, but also have the potential to increase soil fertility through the management of nutrient availability.

Additional Analysis and Explanation

Increasing the availability of phosphorus from natural phosphate fertilizer is an important aspect in increasing agricultural productivity, especially on land that has ultisol soil properties. Ultisol soil often has a low level of fertility, especially in terms of the availability of important nutrients such as phosphorus. Phosphorus is one of the nutrients that is needed by plants for optimal growth, plays an important role in the process of photosynthesis, energy transfer, and DNA synthesis.

Through the addition of acid compounds, such as sulfuric acid, into the soil, chemical reactions that occur can increase the mobilization and availability of phosphorus bound in the soil. This acid helps in dissolving the forms of phosphorus that are less available, so plants can absorb it more effectively. The success in this study shows that acid compounds not only function as a regulator of soil pH, but also have the potential to increase soil fertility through the management of nutrient availability.

Conclusion

Overall, this research not only adds knowledge about the management of ultisol land but also contributes to more efficient and environmentally friendly agricultural practices. This provides encouragement for farmers to explore methods that can increase plant productivity without relying on excessive use of synthetic chemical fertilizers. The use of natural phosphate fertilizers and acid compounds can be a promising approach to increase phosphorus availability in soil and support the success of sustainable agriculture.
