Leaching (agriculture) - Wikipedia
网页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.
Leaching | Soil Chemistry, Nutrient Loss & Pollution | Britannica
网页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.

Soil Leaching - an overview | ScienceDirect Topics
网页Soil leaching is the process where soil nutrients or contaminants are washed away from the surface soil into the subsurface or nearby water bodies due to factors like heavy rainfall or irrigation. AI generated definition based on: …
网页Nutrient leaching is the downward movement of dissolved nutrients in the soil profile with percolating water. Nutrients that are leached below the rooting zone of the vegetation are at least temporarily lost from the system, although they may be recycled if …
Soil Minerals and Plant Nutrition | Learn Science at Scitable

网页2020年8月8日 · 6.3. Soil leaching. During heavy rainfall, irrigation, or recharge events, large volumes of water may come into contact with various substances as soil pore spaces fill (O'Connor and Hou, 2019). In this process, there are complex interactions between gaseous, liquid, and solid phases for soil nutrients, potentially toxic elements, and organic ...
Leaching of Plant Nutrients from Agricultural Lands
网页2017年8月8日 · Nutrient leaching from agricultural soils depletes soil fertility, accelerates soil acidification, increases fertilizer costs for farmers, reduces crop yields and adversely affects the quality of surface and groundwater.
Leaching Mechanisms - ScienceDirect
网页1999年1月1日 · Leaching is a fundamental soil process whereby constituents (soluble elements or suspended particles) are lost from the soil profile by the action of percolating liquid water. It is a common and well documented process which is responsible for the transport of pesticides (and many other elements) from agricultural areas and can lead to …
Leaching of Chemicals in Relation to Soil Structure
网页2014年1月1日 · Leaching – washing out soluble chemicals or other materials from the soil by water percolating through the soil. This can be strongly influenced by the structure of the soil.
