- Liming (soil)
Liming is the application of
calcium andmagnesium rich materials tosoil in various forms, includingmarl ,chalk ,limestone , orhydrated 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.
