Limestone soils are generally very shallow, with a pH of 7 to 8 (neutral to mildly alkaline). They're also nutrient-poor, high in calcium carbonate (CaCO₃), and very well-drained. The unique physical and chemical properties of the soil influence the types of plants that can thrive in this habitat.
Using Limestone for Soil Remineralization. Limestone is a popular choice for soil remineralization due to its high calcium content. Calcium is an essential nutrient for plant growth and is often depleted from soil over time. Limestone is also rich in magnesium, which is another important nutrient for plants. When limestone is added to …
Due to its unique rock properties (e.g., porous nature, rough texture, and high calcium and magnesium content), limestone exhibits a high degree of bioreceptivity. However, the mechanisms underlying the establishment of limestone lithobiontic microbial communities (LLMCs) and the extent to which their composition is influenced by the …

The clay minerals in a soil developed from Lenoir limestone (Ordovician) in Augusta County, Va., are kaolinite and chlorite. The Lenoir limestone contains clay partings consisting of hydrous mica, and the clay in the soil is considered to be residual from that in the parent limestone and modified by soil-forming processes (podzolic).
