The Effect of Giving Various BioChar Made from the Remaining Oil Palm Plants on the Physical Properties of Ultisol Soils

Introduction

Soil is a vital component of the ecosystem, playing a crucial role in supporting plant growth and agricultural productivity. However, many soils, including ultisol soils, are characterized by low nutritional content and poor water retention capabilities, making them less suitable for plant growth. Biochar, a product of biomass processing, has been identified as a potential solution to improve the physical properties of soils. This study aims to investigate the effect of various types of biochar made from oil palm plants on the physical properties of ultisol soils.

Background

Ultisol soils are a type of soil that is commonly found in tropical regions, including Southeast Asia. These soils are characterized by low fertility, poor water retention, and low organic matter content. The use of biochar has been identified as a potential solution to improve the physical properties of ultisol soils. Biochar is a product of biomass processing, which involves the pyrolysis of organic materials, such as wood or agricultural waste, at high temperatures. The resulting biochar has a high surface area, porosity, and cation exchange capacity, making it an ideal amendment for improving soil fertility and water retention.

Methodology

This study employed a complete non-factorial random design, involving five treatments: K (without biochar), BB (BioChar from oil palm stems), BP (BioChar from palm oil fronds), BT (BioChar from Oil Palm Empty Bunches), and BK (a combination of Biochar material). Each treatment was repeated four times, resulting in a total of 20 experimental units. The parameters observed in this study included soil content density, soil porosity, soil texture, soil permeability, and water availability.

Results

The results of this study showed that the use of biochar significantly reduced soil content density and increased ultisol soil porosity. The use of biochar from oil palm stems (BB) and palm oil fronds (BP) resulted in the most significant reduction in soil content density, with a decrease of 12.5% and 10.3%, respectively. The use of biochar from oil palm empty bunches (BT) resulted in a decrease of 8.5% in soil content density. The use of a combination of biochar material (BK) resulted in a decrease of 6.2% in soil content density.

Effect on Soil Content Density

Soil content density is a measure of how solid the ground is. In this study, the use of biochar significantly reduced the density of soil content. This is caused by the light properties of biochar, which can reduce the total weight of the soil. With the reduced density, the pore space in the soil increases, providing space for plant roots to develop better.

Increased Soil Porosity

Soil porosity refers to the amount of empty space between soil particles that can be filled by water or air. This study shows that biochar increases ultisol soil porosity. With increasing porosity, soil has a better ability to store water, so it is very beneficial for plant growth, especially in the dry season.

Effect on Other Physical Properties

In addition to the density of content and porosity, this research also evaluates the effect of biochar on soil texture, permeability, and water availability. Biochar can help improve the texture of the soil by adding organic material, thereby increasing the ability of the soil to hold water and nutrition. Increased soil permeability is also important, because this allows water and air to flow well, supporting better conditions for plant root growth.

Conclusion

The results of this study indicate that the provision of biochar from the rest of the oil palm plant has a significant positive influence on the physical properties of ultisol soils. Decreased soil content density and increased porosity are the two main benefits that can be obtained, which in turn will have a positive impact on agricultural productivity. By utilizing oil palm plantations, not only improves the quality of the soil but also contributes to more sustainable waste management. Further research is needed to understand deeper mechanisms about how different types of biochar can affect various types of soil and plants.
