Zn Sol B ® is a biological fertilizer based on a selected strain of naturally-occurring beneficial autotrophic, acidophilic bacteria Tthiobacillus thioxidans (NCIM - 5065 ) . Tthiobacillus thioxidans is a gram negative , rod shaped , non sporing bacteria. .It is used as an effective soil inoculant.
Zn Sol B ® contains vegetative cells of Tthiobacillus thioxidans . It is formulated as carrier based powder with a potency of 1X and liquid with a potency of 2X , 5X and 10 X. Zn SOL B ® is approved for use in Organic Agriculture.
Mode of Action
Energy metabolism : The bacteria 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.
Thiobacillus thioxidans 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.
Enzyme production : Tthiobacillus thioxidans oxidizes zinc and secretes organic acids which helps mobilize the fixed zinc and makes it available to the plants. This also brings down the pH of the soil and helps in reclaiming alkaline oils..
Method of Application
Seedling treatment : Mix 100 g Zn 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 Zn Sol B ® with compost and apply to an acre of soil.
Drip Irrigation : Mix 3 Kg/ acre of Zn Sol B ® in drip stream
Zn 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.
Zn Sol B ® is stable for a period of 12 months from the date of manufacturing.
