1 Percolation rate means the time expressed in minutes per inch required for water to seep into saturated soil at a constant rate during a percolation test.
2 In the earth sciences, parent rock, also sometimes substratum, is the original rock from which younger rock or soil is formed. ... Parent rock can be sedimentary, igneous or metamorphic. In the context of metamorphic rocks, the parent rock (or protolith) is the original rock before metamorphism occurred.
3 Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. ... Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.
4 Alluvial soil is very fertile as it is rich in mineral nutrients like potash and lime. The black soils are made of extremely fine material, i.e., clayey material. 2. Alluvial soil support many crops like rice, wheat. Cotton grows best in this black soil.
