Product Description

Symbion-P is a Bio fertilizers based on a selective strain of phosphate solubilizing beneficial bacteria, Bacillus megaterium var. phosphaticum. This is available in liquid (1x*0⁹ cells/ml) formulation.
 

Mode of Action

The Bacillus megaterium var. phosphaticum cells contained in the product on reaching soil get activated and produce fresh batches of active cells. These cells grow and multiply by utilizing carbon source in the soil or root exudates. During their growth, by secreting organic acids they solubilize the fixed phosphorus in the soil and make it available to plant in an easily usable form.

Dose and Method of Application

Seed Treatment: Seed required for 1 ha is to be treated with Symbion-P by adopting either seed dipping or seed coating method. Use of proper inoculum and instant sowing of inoculated seeds with minimal waiting period between treatment and sowing are necessary to overcome undue loss of viability between inoculation and sowing.

Seedling Root Treatment: Symbion-P (*0ml/ltr.) in sufficient quantity of water is mixed with field soil or organic fertilizer to form a slurry and the seedling roots are immersed in this slurry for about *0 minutes so that the roots are well drenched in the slurry and the bacteriae get attached to the roots. The seedlings are then either pricked or planted. In case enough organic fertilizer, field soil and farm yard manure are not available, mixing Symbion-P with sufficient amount of water and then dipping the roots of the seedlings can also be done.

Soil Application : Application of Symbion-P (3 lit/ha) mixed with organic fertilizer (**0kgs) and applying it near rhizosphere at optimal temperature and that between *5 to *0 days after crop emergence, has been found to be very effective. Bio-fertilizer and organic fertilizer mixture has to be applied uniformly in the soil and blended well into soil to get the best effect.

Drip System: In places where drip irrigation system is in practice the liquid formulation of Symbion-P can be *@********************0 Litres of water.

Tree Treatments: Symbion-P (Bacillus megaterium) is mixed with water in required and specified rate (****0 ml/Ltrs) and applied nearer the feeder root zone or nearer the trunk following pan irrigation, drip irrigation and the like. The treatment is to be done 2 or 3 times a year. The dosage of Symbion-P (Bacillus megaterium) varies according to varieties, their age, period of the crop, size and canopy of the tree.

Features

• It solubilizes the fixed phosphorous in the soil into a simpler form and makes it available directly to the plants.
• PSB produced organic acid like succinic acid, hastens the maturity and thereby increases the ratio of grain and yield.
• Enhances root proliferation due to release of growth-promoting hormones.

Benefits

• Supplies Phosphorus to the plants to the extent of *0 to *5 kg / ha.
• Saves up to *0% over the cost of phosphorous chemical fertilizer s.
• Avoids soil erosion and improves the soil texture and fertility
• Improves the organic content and microbial population of the soil.
• It improves the plant health.
