Phosphate Solubilizing Bacteria (PSB) are beneficial bacteria capable of solubilizing inorganic
phosphorus from insoluble compounds.
P.S.B PLUS-Caps are capsules that contain a phosphate-solubilizing bacteria that solubilizes the
inorganic soil phosphates of Ca, Fe, and Al via the production of siderophores, several acids
(organic), hydroxyl, and carboxyl groups, and then chelating them to the bound phosphates.
BENEFITS
• Increased Phosphorus availability.
• Improved plant growth and development.
• Reduced reliance on chemical fertilizers.
• Enhanced Nutrient Mobilization. (Fe, Zn, & Cu)
• Improved soil Health.
• Promoting the breakdown of organic matter.
• Enhancing soil structure.
• Environmentally friendly.
• Compatible with other beneficial microbes.
PACKAGING
1 Box = 1 Capsule
RECOMMENDED
• Fixation of soil phosphorus increases
with time of contact between soluble
phosphorus and soil particles.
Consequently, more efficient utilization
of fertilizer.
• Phosphorus is generally obtained by
applying the fertilizer shortly before
planting the crop.
• It is also used before the flowering and
fruiting stage to increase the yield.
How to Use Encapsulated Biofertilizers
Standard Method
1. Activation:
o Dissolve 1-3 capsules of the same type in 1 liter of clean water.
o Let the solution sit for 3-4 hours, stirring occasionally.
o Solution Preservation: The activated one litre solution can be stored for a
maximum of 10-12 hours.
o Solution Usage: Once activated, the solution should be used within the 10-12 hour
period.
2. Application:
o Drip/sprinkler Irrigation: Mix the activated solution with the required amount
of water in a drum and insert a venturi. Irrigate the field with this solution.
o Drenching: Mix the activated solution with water and pour it directly onto the
soil near the plant roots.
o Broadcasting: Mix the activated solution with 50-100 kg of soil, vermicompost,
or sand per acre (or 125-150 kg per hectare) and broadcast the mixture.
o The amount of water required for irrigation completely depends on type of crop,
soil and climatic conditions.
Instant Method (Using an Activator)
1. Activation:
o Place up to 10 capsules of the same type in an activator with a small amount of
water.
o Pull the activator's string 10-12 times to dissolve the capsules.
o Solution Preservation: The activated one-litre solution can be stored for a
maximum of 10-12 hours.
o Solution Usage: Once activated, the solution should be used within the 10-12 hour
period.
o The amount of water required for irrigation completely depends on type of crop,
soil and climatic conditions.
2. Application:
o Follow the same application methods as in the Standard Method (drip irrigation,
drenching, or broadcasting).
PRECAUTIONS: -
Water Quality: Use clean, chemical-free water for activation.
Storage: Store capsules in a cool, dry place.
Timing: Apply biofertilizers at appropriate crop growth stages. Use Bio-fertilizer before
or after 6-7 days of use of chemical fertilizer or pesticides.
Avoid Mixing with Chemicals: Do not mix biofertilizers with chemical fertilizers or
pesticides
