Acid mine drainage (AMD) is a significant environmental problem in most countries that have an extensive history of mining. AMD refers to the acidic water that can be produced during hard and soft rock mining. Acidic drainage forms when sulfide minerals, primarily pyrite, are exposed to oxygenated surface waters.

Agricultural transformation in Ethiopia requires the appropriate use of soil resources. About 43% of Ethiopia's agricultural land is affected by soil acidity and 28% is estimated to be strongly acidic with soil pH ranging between 4.1 to 5.5 (ATA, 2014; Abebe, 2007; Agegnehu et al., 2019; 2021).Soil acidity can lead to low crop yields and in severe cases, may result in …

About Limestone. Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCO3) in the form of the mineral calcite or aragonite. It is a kind of stone widely found in nature. Limestone can be directly processed into stone using crushing equipment and fired into quicklime. Quicklime absorbs moisture or adds water to become hydrated lime.

in slightly acidic to neutral soils. • Aglime boosts the performance of certain herbicides. As with fertilizer, modern herbicides are most effective when soil pH is slightly acidic (pH of 6.5) to neutral (pH of 7.0). When soils are more acidic, herbicides attach to soil particles, reducing their ability to control weed growth.

Soil Amendment: Limestone enhances soil fertility by neutralizing acidity, improving pH levels, and promoting nutrient availability for optimal plant growth. Building Materia l: Limestone serves as a durable and aesthetically …

The finely crushed particles of limestone improve soil structure by increasing porosity and water retention, which aids in root development and prevents soil erosion. Its calcium and magnesium content also enrich the soil with essential nutrients, fostering healthier plant growth and enhancing overall soil fertility.

Improves soil structure: By improving porosity and lowering compaction, crushed limestone can assist enhance soil structure. Better drainage, aeration, and water retention are made possible as a result, all of which can promote plant development. Reduces soil erosion: Crushed limestone put to the soil might aid in reducing soil erosion.

Abstract Sudbury, Ontario, Canada experienced severe environmental degradation from intensive logging, mining, and smelting activities. Acidification and erosion of soils, as well as heavy metal deposition led to widespread vegetation mortality and the creation of 20 000 ha of barren and 80 000 ha of semi-barren land within the Sudbury region. Restoration …
