Fe Sol B ® is a biological fertilizer based on a selected strain of naturally-occurring beneficial autotrophic, acidophilic bacteria Acidithiobacillus ferrooxidans (NCIM 5370 ) . Acidithiobacillus ferrooxidans is a gram negative , rod shaped , non sporing bacteria. .It is used as an effective soil inoculant.
Fe Sol B ® contains vegetative cells of Acidithiobacillus ferrooxidans . It is formulated as carrier based powder with a potency of 1X and liquid with a potency of 2X , 5X and 10 X. Fe SOL B ® is approved for use in Organic Agriculture.
Mode of Action
Enzyme production : Acidithiobacillus ferrooxidans release an iron oxidase, which allows them to metabolize ferrous/ iron.
Energy metabolism : They require inorganic molecules as an electron donor and inorganic carbon (such as carbon dioxide) as a source. They obtain nutrients by oxidizing iron and sulfur with O2.
Acidthiobacillus ferrooxidans grows at pH values of 4.5 to 1.3 in basal salt medium and derives its biosynthetic requirements by autotrophy i.e it used carbon from atmospheric carbon dioxide. It also fixes Nitrogen in acidophilic habitats. The bacteria derive its metabolic energy by oxidation of reduced inorganic sulfur compounds or ferrous ions. Anaerobic growth happens by using elemental hydrogen or reduced inorganic sulfur compounds as electron donors and ferric ions as electron acceptors.
Method of Application
Seedling treatment : Mix 100 g Fe Sol B ® with sufficient quantity of water and organic manure to form a slurry. The seedlings are dipped in this slurry for 30 minutes prior to planting so that the bacteria gets attached to the roots.
Soil application : Mix 3-5 Kg/ acre of Fe Sol B ® with compost and apply to an acre of soil.
Drip Irrigation : Mix 3 Kg/ acre of Fe Sol B ® in drip stream
Ferrous / Iron mobilization.
Fe Sol B ® is suitable for application on Cereals , Millets , Pulses, Oilseeds, Fibre Crops , Sugar Crops , Forage Crops , Plantation crops ,Vegetables, Fruits, Spices , Flowers , Medicinal crops , Aromatic Crops , Orchards and Ornamentals.
Fe Sol B ® is stable for a period of 12 months from the date of manufacturing.
