ABSTRACT

Humic acid is an organic matter present in soil which contains humus, humin, humate. It contains carbon compounds which have originated from earth’s structured components. The molecular size of humic acid range from 10,000 to 100,000. They are from salts with inorganic trace mineral elements. These trace elements are bound to humic molecules in a form that can be readily utilized by various living organisms. They are considered to be a flexible linear polymer. On average 35% of humic acid is aromatic, remaining are aliphatic molecules. Humic acid plays an important role in ion exchange and metal chelating systems. Humic acid are highly applicable in the rooting stage of plants. They are nontoxic and have very good water holding capacity from the soil. Musa accuminata is a banana species where originated in tropic and subtropic region which contains energy and nutrients. Fulvic acid are a mixture of weak aliphatic and aromatic acids. It ranges approximately from 1,000 to 10,000 and smaller that of humic acid. It plays a significant role in proliferation of plant species. It has relatively small size which can readily enter plant roots, stems, and leaves. They carry trace minerals from plant surfaces into plant tissues. It can be used as primary production technique for maximizing the plant protecting capacity. They are most effective carbon containing chelating compounds. It shows plant compatibility and are nontoxic, when applied at relatively low concentrations.
