Answer:
This study is an overview of previous studies on lime (quick and hydrated) -treated soil. Lime is the oldest traditional stabilizer used for soil stabilization. The mechanism of soil-lime treatment involves cation exchange, which leads to the flocculation and agglomeration of soil particles. The high pH environment then causes a pozzolanic reaction between the free Ca+2 cations and the dissolved silica and alumina. Lime-treated soil effectively increases the strength, durability and workability of the soil. Such treatment also improves soil compressibility. A fluctuation behavior was observed on the influence of lime on soil permeability. However, the factors affecting the permeability of the soil-lime mixture should be extensively studied. Nonetheless, lime treatment has a number of inherent disadvantages, such as carbonation, sulfate attack and environment impact. Magnesium oxide/hydroxide are thus proposed as a suitable alternative stabilizer to overcome at least some of the disadvantages of using lime in soil stabilization.

Actually I have a pdf on it to explain more if you want but how to get it to you is the issue. well I'm guessing the one I've put out should be very much okay, I hope so .
Limestone and lime are used to neutralize acidic soils, enhancing the availability of essential nutrients for plants and reducing toxicity. Finer lime particles are more effective, though impurities in limestone can affect its performance. Timely application and consideration of regional soil types are critical for effective treatment.
Limestone and lime are commonly used to neutralize acidic soils or water bodies. The main advantage of using these substances is that they can effectively raise the pH of the soil or water, making it more hospitable for plant growth and aquatic life.
Agricultural lime, typically made from crushed limestone or chalk, is rich in calcium carbonate (CaCO₃) and is used to reduce soil acidity. This is essential for the availability of nutrients like nitrogen, potassium, and phosphorus, which are vital for plant health. Furthermore, lime can be applied to pit latrines to neutralize acidic waste.
However, there are disadvantages to using lime. It takes time for limestone to dissolve and neutralize the soil, depending on the size and purity of the lime particles used. Finer lime particles are often preferred as they have a larger surface area that reacts more quickly. While limestone primarily consists of CaCO₃, it may contain impurities which can affect its effectiveness.
Lime treatment is crucial when the soil has a low pH, leading to decreased nutrient availability and potential toxicity from elements like aluminum. By using ag lime or dolomitic limestone, which contains magnesium, soil pH can be raised to create a more viable growing environment. This is especially true in areas with limestone bedrock, which can also contribute to buffering acid rain effects.
