Bio Bhumi is a biological fertilizer based on a selected strain of naturally-occurring beneficial eubacteria Bacillus megaterium (NCIM 2087, ATCC 10778). Bacillus megaterium is a gram-positive, rod-shaped, endospore-forming bacteria. It is used as an effective soil inoculant. Bio Bhumi contains endospores of Bacillus megaterium.

Phosphorus is abundant in several soils and is one of the major nutrients limiting the plant growth. The overall Phosphorus use efficiency following phosphate fertilizer application is low because of the formation of insoluble complexes Therefore this mandates frequent application of soluble forms of inorganic Phosphorus necessary for crop production. This results in leaching to the groundwater and results in eutrophication of aquatic systems and pollutes the soil.

Phosphorus is an important macronutrient which is applied to soil in the form of phosphatic fertilizers. A large portion of this soluble inorganic phosphate applied to the soil as chemical fertilizer is immobilized rapidly and becomes unavailable to plants. Bio Bhumi aids in the transformation of soil Phosphorus into an assembly form and is, therefore, an integral part of the soil Phosphorus cycle as they help in releasing Phosphorus from inorganic and organic pools of total soil Phosphorus through solubilization and mineralization.

Mode of Action:

Carbon utilization: The bacteria contained in P Sol B ® -BM on application to the soil get activated and multiply by utilizing the carbon source of soil or exudates of the root and in this process secrete organic acids and enzymes.

Metabolite production: Bacillus megaterium produces organic such as lactic acid, gluconic acid, citric acid, succinic acid, propionic acid and enzymes that help solubilize the fixed phosphorus into exchangeable form. These organic acids through their hydroxyl and carboxyl groups chelate the cations (mainly Calcium) bound to phosphate converting them into the soluble forms. An inverse relationship is observed between the pH and soluble-Phosphorus concentration which indicates that organic acid production by phosphor bacteria plays a significant role in the acidification of the soil medium facilitating Phosphorus solubilization and easier assimilation by plants.

Target Nutrition Phosphorus mobilization.

Crops: Shakti BM 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.
