Soil forming process of leaching
WebIn Soil enrichment, matter organic or inorganic is added to the soil . In Removal processes, material is removed from the soil body. This occurs when erosion carries soil particles into rivers and streams. Leaching – The loss of soil compounds and minerals by solution in water flowing to lower levels is another important removal process. WebThe Leaching process is a universal process – Water will leach the components of any material it comes in contact with, from its surface or the interior of the material (based on the porous nature of the material). Using this process, the ore of metal can be concentrated by causing a chemical reaction with a reagent which would lead to the ...
