Multiplex Nalpak NPK Bacterial Consortium Biofertilizer – Granular

Multiplex Nalpak NPK Biofertilizer for Improved Soil Nutrient Availability

Multiplex Nalpak is an NPK bacterial-consortium biofertilizer containing beneficial microorganisms that help improve the availability of nitrogen, phosphorus and potassium in the soil. The supplied product image represents the 3 kg granular formulation.

Nalpak combines nitrogen-fixing, phosphorus-solubilising and potassium-mobilising bacteria. These beneficial microorganisms support nutrient cycling, soil biological activity, root development and healthy crop growth when used as part of an integrated nutrient-management programme.

Key Features of Multiplex Nalpak

• Three-way nutrient support: Combines microorganisms associated with nitrogen fixation, phosphorus solubilisation and potassium mobilisation.
• Soil biological support: Helps increase beneficial microbial activity in the crop root zone.
• Nutrient availability: Supports the conversion or mobilisation of selected soil nutrients into forms that plants can utilise.
• Root-zone activity: Works in association with the soil and crop rhizosphere rather than acting as a direct chemical NPK fertilizer.
• Multiple formulations: Available in liquid, carrier powder and granular forms for different application requirements.
• All-crop suitability: Recommended for all crops according to formulation-specific label directions.

Benefits for Farmers

• Supports the physical, chemical and biological condition of cultivated soil.
• Helps improve nutrient cycling in the root zone.
• Supports biological nitrogen fixation through beneficial bacteria.
• Helps solubilise fixed or complex phosphorus present in the soil.
• Helps mobilise soil-bound potassium for plant use.
• Supports root growth, crop establishment and vegetative development.
• May support microbial production of amino acids, vitamins and growth-promoting substances.
• Can be incorporated into an integrated nutrient-management programme.
• Supports crop productivity under proper soil, irrigation and nutrient-management practices.

The manufacturer states that Nalpak may support a 10–30% increase in crop yield. Actual response is not guaranteed and can vary with crop, soil fertility, climate, formulation quality, microbial survival and overall farm management.

Dosage and Application Methods

Granular dose note: A 3 kg pack is the available granular pack size; pack size does not automatically confirm the per-acre dose. Since the official online page does not separately state the granular dosage, confirm the exact dose from the label printed on the 3 kg pack before application.

Seed Treatment Method

1. Take the quantity of seed required for one acre.
2. Prepare approximately 500 ml of rice starch water or jaggery solution.
3. Add 100 ml liquid Nalpak or 500 g carrier-based Nalpak to the prepared solution.
4. Mix thoroughly to obtain a uniform coating mixture.
5. Coat the seeds evenly with the prepared biofertilizer mixture.
6. Keep the treated seeds under shade for approximately one hour.
7. Sow the treated seeds soon after shade drying.
8. Do not dry treated seeds under direct sunlight.

Seedling Root-Dip Method

1. Mix 250 ml of liquid Nalpak in 50 litres of clean, non-chlorinated water.
2. Carefully place the seedling roots in the prepared solution.
3. Allow the roots to remain dipped for approximately 10–20 minutes.
4. Remove the seedlings carefully without damaging the roots.
5. Transplant the treated seedlings promptly into a prepared and moist field.

Main-Field Soil Application

1. Use the dose specified for the selected Nalpak formulation.
2. For liquid Nalpak, use 2 litres per acre as per the official recommendation.
3. For carrier powder, use 5 kg per acre as per the official recommendation.
4. Mix the product thoroughly with approximately 100 kg of dried farmyard manure or Multiplex Annapurna.
5. Broadcast the prepared mixture uniformly over one acre.
6. Apply in moist soil and incorporate lightly where recommended.
7. Provide suitable irrigation after application to support microbial establishment.
8. For the 3 kg granular pack, follow the exact directions printed on its label.

Mode of Action

Azotobacter chroococcum helps fix atmospheric nitrogen in the crop root zone, supporting biological nitrogen availability. It does not replace the complete nitrogen requirement of a high-yielding crop.

Bacillus megaterium produces organic acids and related compounds that help solubilise complex soil phosphates, making a portion of the fixed phosphorus more available in the rhizosphere.

Frateuria aurantia helps mobilise potassium that is present in less-available soil forms. This supports better access to existing soil potassium under suitable biological and soil conditions.

Why Farmers Can Choose Multiplex Nalpak

• Combines N-fixing, P-solubilising and K-mobilising bacteria.
• Supports biological availability of three primary plant nutrients.
• Recommended for all crops according to formulation-specific instructions.
• Available in liquid, powder and granular variants.
• Suitable for seed, seedling, nursery, soil and drip applications depending on formulation.
• Supports soil biological activity and integrated nutrient management.
• Useful alongside recommended organic and mineral nutrient inputs.

Frequently Asked Questions

What is Multiplex Nalpak?

Multiplex Nalpak is an NPK bacterial-consortium biofertilizer containing beneficial microorganisms associated with nitrogen fixation, phosphorus solubilisation and potassium mobilisation.

Does Nalpak contain chemical NPK fertilizer?

Nalpak is not a conventional chemical NPK fertilizer. Its microorganisms help fix, solubilise or mobilise selected nutrients in the root zone. Continue the recommended crop-nutrition programme unless a qualified agricultural specialist advises otherwise.

What is the Nalpak dose per acre?

The official dose is 2 litres per acre for the liquid formulation and 5 kg per acre for the carrier powder. Confirm the separate dose of the 3 kg granular formulation from its physical pack label.

Is the 3 kg granular pack sufficient for one acre?

The available granular pack weighs 3 kg, but the official online page does not state its separate per-acre dosage. Do not assume that one pack treats one acre; check the directions printed on the granular pack.

Which crops can be treated with Nalpak?

Nalpak is recommended for all crops, including cereals, pulses, oilseeds, vegetables, fruits, cotton, sugarcane, plantation crops and flowers.

Can Nalpak be applied through drip irrigation?

The liquid formulation may be applied through drip irrigation at 2 litres in approximately 200 litres of water per acre, subject to the product label and proper filtration of the irrigation system.

Can Nalpak replace all chemical fertilizers?

No. Nalpak supports nutrient availability but should not be presented as a complete replacement for the crop's recommended fertilizer requirement. Use it as part of integrated nutrient management based on soil testing.

Can Nalpak be mixed with fungicides or insecticides?

No. The manufacturer states that Nalpak should not be mixed with insecticides, fungicides or weedicides because these products may harm the beneficial microorganisms.

Can Nalpak guarantee a 10–30% yield increase?

No yield increase can be guaranteed. The manufacturer reports a potential increase of 10–30%, but actual results depend on crop, soil, weather, irrigation, nutrient management, microbial viability and application practices.

How should Nalpak be stored?

Store it in its original sealed pack in a cool, dry and shaded place. Protect the product from direct sunlight, excessive heat and chemical pesticides, and use it before the expiry date printed on the pack.
