| Abstract | Humic acid have been successfully extracted from leonardite using base-acidtreatment. Humic acid is an essential part of soil. This material, present in good soil,makes available of uptake to the plant and the soil nutrients for improving thephysical structure of the soil. To extract humic and fulvic acid, the Leonardite isprocessed in a strongly basic aqueous solution. To precipitate the humic acid, thesolution is adjusted to pH 1 with a mineral acid. Carbon, Oxygen, Nitrogen,Aluminium, Silicon and Potassium were extracted from humic acid in humate form(Humic acid reacted with KOH). Rice grower have expressed interest about usinghumate as a soil fertilizer. This research, humic acid was used to amend soils toincrease organic matter and application on rice berry growth. In addition, humic acidand leonardite was beneficial to leaf and root growth of rice berry compared with thecontrol. |
