Assessing the risk of N leaching across a steep N deposition
Once the chemicals have drained down through the soil, they can leave a crust of soluble salts on the surface, which makes it hard for the soil to absorb water. Removing this crust with water is the other type of leaching. Leaching is a physico-chemical process where minerals in rock masses go through dissolution under percolating water and anion/cation exchange reactions to generate metal salts in solute/colloid phase that migrate and accumulate under hydrological forces. leaching n. noun: Refers to person, place, thing, quality, etc.

Nitrate leaching is also a signiﬁcant source of soil acidiﬁcation. In humid climates, some nutrient leaching occurs even under natural vegetation, but agricultural activities can greatly increase leaching losses (Havlin et al., 1999).

This transport results in a porous and open top layer and a dense, compact lower layer. 2014-10-30 · Leaching is the selective corrosion in which one element is removed from a solid solution alloy. The gradual loss of zinc from brass (dezincification) is perhaps the most well-known example of this type of corrosion, but aluminum can also be leached from aluminum bronzes (dealuminification) and nickel from 70/30 cupronickel alloys (denickelification).
