Humic acid have been successfully extracted from leonardite using base-acid treatment. 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 the physical structure of the soil. To extract humic and fulvic acid, the Leonardite is processed in a strongly basic aqueous solution. To precipitate the humic acid, the solution 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 …
