Introduction

Geochemical weathering is a crucial process that affects the formation of soil and its fertility. It is a complex process that involves the breakdown of rocks into parent material, which is then transformed into soil through various mechanisms such as oxidation, reduction, hydration, carbonation, and acidification. The study of geochemical weathering is essential in understanding the characteristics of weathered rocks and its implications for soil fertility and sustainable land management. This article presents a study on geochemical weathering on tuff rocks in Lingga Julu Village, Simpangempat District, Karo Regency, and discusses its implications for soil fertility and sustainable land management.

Geochemical Weathering Process

Geochemical weathering is a rock weathering process that produces parent material as a result. This process occurs in the soil solum (Horison R) and involves several important mechanisms such as oxidation, reduction, oxidation-reduction, hydration, carbonation, and acidification. These processes cause changes in the crystalline structure of rocks, leading to changes in solubility and volume of rocks, thus making rocks experience weathering. The geochemical weathering process is instrumental in soil formation and can affect land fertility.

Study Area and Methods

The study was conducted in Lingga Julu Village, Simpangempat District, Karo Regency, where tuff rocks are abundant. The methods used in this study included laboratory surveys and analysis. Laboratory analysis consisted of total analysis of chemical compounds in horizons R and C, texture analysis, and mass density analysis. The results of the analysis were used to understand the characteristics of weathered tuff rocks and its implications for soil fertility and sustainable land management.

Results and Discussion

The results of the analysis showed that if Sio₂ is considered constant, then the compounds of CaO and Na₂o have increased, while P₂o₅ and K₂O have decreased. If Al₂o₃ is considered constant, the Cao and Sio₂ compounds also increase, while P₂o₅ and MGO have decreased. Increased Sio₂ and CaO make it more difficult to experience weathering, and tuff dacit is rich in calcium minerals. Quartz minerals (Sio₂) are relatively more stable than other minerals because they have a stronger Si-O bond. Meanwhile, phosphorus minerals (P₂o₅) show the most significant weight loss because these minerals are more easily weathering compared to silica.

The results of the study also showed that the composition of minerals rich in calcium provides benefits in terms of soil fertility, but also creates challenges in terms of land management. Increasing the concentration of CaO and Na₂o can show the potential to increase soil pH, which in turn can affect the availability of nutrients for plants. In texture analysis, it is important to consider the proportion of sand, dust, and clay, because this will affect drainage and water retention in the soil. These two factors are very important in agriculture, especially in regions with irregular rainfall.

Implications for Soil Fertility and Sustainable Land Management

The results of this study provide valuable insights on the characteristics of weathering geochemicals of tuff and implications for soil fertility. The data obtained can be used to plan better and sustainable land management practices. In addition, a deep understanding of the weathering process can also help in the conservation and rehabilitation of degraded land. With the increasing understanding of the relationship between geochemical weathering and soil fertility, it is hoped that farmers and land managers can make more appropriate decisions in managing their natural resources.
