Lime Requirement Determination of Tropical Peat Soils

Lime Requirement Determination of Tropical Peat Soils

Tropical peat soils are acidic usually with pH values less than 4 and have very low exchangeable bases. The acidity develops as a consequence of dissociation of the functional groups, such as carboxyl and phenolic hydroxyl groups attached to the humic substances of organic matter. Liming is a st...
