Subbituminous coal was employed as raw material for the extraction of humic acid (HA) to be applied as application for the plant growth. These can be obtained from carbonaceous substances by extraction methods based on their solubility, which allows their separation into humic acid (HA), fulvic acid (FA) and humin (Hu). Humic acid (HA), known as the black gold of agriculture, is increasingly becoming popular for use in agriculture. We show that humic acid (HA) is a good soil amendment that can be used to overcome salinity stress. Experiments were designed to evaluate the effects of humic acids extracted from subbituminous coal and compare them with the action of commercial humic acid in combination with a plant growth. Importantly, the results demonstrate that humic acid (HA)/fulvic acid (FA) extracted from subbituminous coal can be applied as various applications. |
