Detailed explanation-1: -In agriculture, leaching is the loss of water-soluble plant nutrients from the soil, due to rain and irrigation. Soil structure, crop planting, type and application rates of fertilizers, and other factors are taken into account to avoid excessive nutrient loss.
Detailed explanation-2: -leaching, in geology, loss of soluble substances and colloids from the top layer of soil by percolating precipitation. The materials lost are carried downward (eluviated) and are generally redeposited (illuviated) in a lower layer. This transport results in a porous and open top layer and a dense, compact lower layer.
Detailed explanation-3: -The process of leaching includes the partitioning of contaminants between a solid and liquid phase (e.g., assuming local equilibrium) coupled with the mass transport of aqueous or dissolved constituents.
Detailed explanation-4: -Leaching is a process in which soil nutrients are released into contacting water phase. The leaching of the essential plant nutrients is influenced by pedoclimatic and soil crop management practices.
