What Is Leaching In Soil: A Gardener Should Know - Www ...

Sep 15, 2017· What is Leaching in Soil? In layman's terms, leaching in soil means leaking of water down the soil. The soil is more like a sponge. When it rains, the top part of the soil absorbs as much water, keeping the moisture available for the plants. However, when the soil is filled with water more than it can hold, leaching occurs.

Solid-Liquid Extraction (( Leaching

Solid-Liquid Extraction ((Leaching )) Leaching: is the separation of a solute from solid mixture by dissolving it in a liquid phase. Leaching occurs in two steps: 1. Contacting solvent and solid to effect a transfer of a solute (leaching). 2. The separation of the solution from the remaining solid (washing).
