Liming (soil)

From Wikipedia, the free encyclopedia

Liming is the application of calcium and magnesium rich materials to soil in various forms, including marl, chalk, limestone, or hydrated lime. This neutralises soil acidity and increases activity of soil bacteria. However, oversupply may result in harm to plant life.

Over-liming is most likely to occur on soil which has low buffering capacity, such as sand which is deficient in buffering agents such as clay and organic matter.[1]

An agricultural study in Hogward, Germany that compared tree stocks 2 and 20 years after liming found that liming promotes nitrate leaching and decreases the phosphorus content of some leaves. [2]
