leaching

Generally leaching is the dissolution of elements from a surface into the surrounding fluid medium. For the soldering community, the term applies to the action of liquid solder dissolving metals such as silver from surfaces. A particular case where leaching has been observed is the chip ceramic capacitor, whose inner terminals are typically of sil...

leaching

leaching occurs when rainfall or irrigation water flushes substances and nutrients through soil. Leaching is primarily performed to remove the buildup of harmful nutrients, including salt. After leaching, it's important to fertilize your lawn with nutrients that promote growth, such as nitrogen. This can be done by applying high quality lawn fertil...

leaching

The removal or loss of excess salts or nutrients from soil. The soil around over fertilized plants can be leached clean by large quantities of fresh water used to 'wash' the soil. Areas of extremely high rainfall sometimes lose the nutrients from the soil by natural leaching.

[pedology] In pedology, leaching is the loss of mineral and organic solutes due to percolation. It is a mechanism of soil formation distinct from the soil forming process of eluviation, which is the loss of mineral and organic colloids. Leached and elluviated materials tend to be lost from topsoil and deposited in subsoil. A soil horizon ac...

[metallurgy] Leaching is a widely used extractive metallurgy technique which converts metals into soluble salts in aqueous media. Compared to pyrometallurgical operations, leaching is easier to perform and much less harmful, because no gaseous pollution occurs. Drawbacks of leaching are the highly acidic and in some cases toxic residual eff...
