Discover the complete list of biofertilizers and their uses. Boost soil fertility, crop yield, and sustainable farming results with these top biofertilizer types.
In today’s competitive agricultural landscape, growers are doubling down on nature-powered inputs—especially biofertilizers. They’re cost-efficient, environmentally aligned, and deliver long-term soil productivity. If you're looking to future-proof your farm or educate your audience, understanding biofertilizers is non-negotiable. This guide breaks down the major types of biofertilizers, their exact uses, and how they transform crop performance. Let’s get straight to it.
What Are Biofertilizers?
Biofertilizers are live microbial products that enhance soil fertility by fixing atmospheric nutrients, improving soil health, and boosting plant growth. Instead of forcing crops with chemicals, biofertilizers partner with nature—strengthening plants in a sustainable, scalable way.
This isn’t just modern innovation. It’s a return to age-old soil practices, reinvented with science.
Top Biofertilizers List and Their Uses
Below is a comprehensive, agriculture-tested list of biofertilizers and how they deliver value crop-by-crop.

-
Enhances seed germination.
-
Increases root volume and plant vigor.
-
Strengthens plants against drought and soil-borne diseases.
3. Azospirillum
Best Use: Cereals and fodder crops
How It Works: Fixes nitrogen and stimulates plant hormones.
Benefits:
-
Bigger root mass.
-
Strong tillering in paddy.
-
Higher biomass for fodder production.
4. Blue-Green Algae (BGA)

-
Increases rice grain weight and panicle count.
6. Phosphate Solubilizing Bacteria (PSB)
Best Use: All crops
How It Works: Converts unavailable phosphorus into plant-available forms.
Benefits:
-
Improves root strength.
-
Reduces P fertilizer requirement.
-
Increases flowering and fruit-setting.
7. Potassium Mobilizing Bacteria (KMB)
Best Use: Fruit crops, vegetables, grains
How It Works: Mobilizes locked potassium in soil.
Benefits:
-
Enhances plant disease resistance.
-
Improves fruit quality, size, and color.
-
Boosts overall plant metabolism.
8. Mycorrhiza
Best Use: Horticulture, plantation crops
How It Works: Forms fungal associations with roots to increase nutrient uptake.
Benefits:
-
Improves water retention.
-
Enhances phosphorus absorption.
-
Delivers superior root development in orchards like mango, guava, banana.
9. Trichoderma
Best Use: All crops
How It Works: Soil-friendly fungi with biocontrol properties.
Benefits:
-
Protects roots from fungal diseases.
-
Enhances root growth and soil structure.
-
Works as a natural plant growth promoter.
10. Plant Growth Promoting Rhizobacteria (PGPR)
Best Use: Vegetables, cereals, cash crops
How It Works: Colonizes the rhizosphere and promotes growth through nutrient solubilization.
Benefits:
-
Balanced nutrient uptake.
-
Better resistance to stress.
-
Consistent yield improvement.
How to Apply Biofertilizers Effectively
To extract maximum value, follow industry-standard application practices:
✔ Seed Treatment
Coat seeds with biofertilizer slurry before sowing.
✔ Soil Application
Mix with compost and broadcast evenly across the field.
✔ Root Dipping
Suitable for paddy, vegetables, and nursery plants.
✔ Drip Irrigation
Delivers microbes directly to the root zone.
When applied the right way, biofertilizers outperform chemical fertilizers in long-term soil regeneration and profitability.
Benefits of Using Biofertilizers
Here’s the strategic upside for farmers and agribusinesses:
-
Cuts fertilizer costs 25–40%.
-
Enhances soil microbial life.
-
Increases yield sustainably.
-
Improves nutrient availability.
-
Builds long-term soil resilience.
-
Supports organic certification standards.
In short, biofertilizers unlock farm productivity that aligns with both tradition and the evolving future of agriculture.
Conclusion
Biofertilizers are not just an eco-friendly alternative—they’re a competitive advantage for modern farmers. With rising input costs and soil degradation issues, switching to biological fertilizers is a forward-thinking move that still respects time-tested agricultural wisdom. Whether you're growing cereals, pulses, vegetables, or fruits, integrating biofertilizers is your roadmap to healthier soil and higher yields.
FAQs
1. Are biofertilizers suitable for all crops?
Yes. Different categories benefit different crops, but every crop can utilize at least one type.
2. Can biofertilizers replace chemical fertilizers completely?
They reduce dependency significantly but may not fully replace chemicals in high-demand crops.
3. How long do biofertilizers take to show results?
Typically 15–30 days, depending on soil health and application method.
4. Do biofertilizers improve soil structure?
Absolutely. They increase organic matter, microbial activity, and nutrient availability.
5. How should biofertilizers be stored?
Keep them in a cool, dry place away from direct sunlight to maintain viability.
