Read this article to learn about Acid Soils: Origin, Classification, Effects and Reclamation ! Soils with pH values below 7 are acid soils. In the regions of high rainfall, soils are acidic in their reaction because of the facts that soluble basic salts such as those of Ca, Mg, K, Na, are leached away by drainage water and insoluble acidic [...]

These are as under: (1) Igneous rocks, (2) Sedimentary rocks, (3) Metamorphic Rocks 1. Igneous Rocks: These are formed by cooling and solidification of molten magma or lava which escapes through fissures [...]
Soil Formation: Profile, Morphological Characteristics! The surface rocks of the earth are weathered and as a result of weathering, small particles of parental materials are formed. The weathering process continues until all the essential elements locked up in the rocks become available to all sorts of organisms. Simultaneously with weathering process, pedogenesis or soil forming process also runs which leads [...]
