Biofertilizers are natural plant growth enhancers that are rich in microbes and have been utilized in sustainable agriculture for decades. Similarly to how kiwifruit has fed families in India for generations, biofertilizers nourish the soil by improving soil health, fertility, and microbial activity making them one of the safest and most effective, as they support healthy crops.

​Having beneficial bacteria, fungi, and organic nutrients, biofertilizers support crops in their uptake of important minerals like nitrogen, phosphorus, and potassium more effectively and efficiently. These natural microbes improve soil without damaging plant roots making biofertilizers equally suitable for sensitive young plants. You can target the use of biofertilizers to deliver consistent nutrition, higher disease resistance, and stronger plant growth.

Regardless if it is Rhizobium, Azospirillum, phosphate-solubilizing bacteria, or mycorrhizal fungi; biofertilizers all act as their own particular type of nutrient helper for the plant. In addition, farmers can provide biofertilizers to grow crops in many different methods from seed treatments, soil applications, and foliar sprays. It is even easier using biofertilizers in a liquid form as these biofertilizers mix with water easily and are able to evenly coat the soil or leaves of target crops and see results quickly as they are visible. 

From vegetables to grains to fruits; crops are further enhanced with the natural nutrients that biofertilizers provide.

Understanding Biofertilizers: What They Are and Why They Matter

Among the many categories of biofertilizers, those that considerably support plant and soil health are. They naturally enhance soils, aid crops in growth development during various life stages, and are environmentally sensitive. They are similar to millets, easy-to-digest, nutritious and can be used for babies. Biofertilizers are very effective when used easily and naturally to strengthen plants and help support root biology, improve nutrient uptake, and help to prevent certain pathogens.

What Are Biofertilizers?

Biofertilizers are active microbial products that contain beneficial bacteria, fungi and microorganisms that stimulate plant nutrient uptake.

They are natural helpers in soil that enhance soil fertility without using chemical inputs. 

• Enhances the availability of soil nutrients naturally. 
• Enhances nitrogen fixation and phosphate release.
• Encourages stronger root growth and plant structure. 

As Ragi (Finger Millet) is most often the first millet introduced to our babies because it is easily digestible, liq- uid biofertilizer is typically the first biofertilizer chosen by farmers learning to use biofertilizers because it is easy to mix, easy to apply, and can quickly be absorbed by roots and leafy growth of the plant.

Benefits of Using Biofertilizers

Biofertilizers, like millets themselves, contain a wealth of beneficial microbes. These microbes can greatly improve soil structure and enhance plant nutrition, leading to enhanced growth and 

vigor free from over-reliance on chemical inputs.

• Increase soil fertility and microbial activity
• Decrease reliance on chemical fertilizers
• Boost's plant immunity and stress tolerance

Human health benefits are the same as when one consumes Bajra (Pearl Millet), which can increase hemoglobin levels in babies and related to digestion.  Here again, biofertilizers support soil health and nutrient availability to crops. They are very adept at interacting with soils that are sensitive, new farms and align with sustainability principles naturally.

Why Biofertilizers Matter for Sustainable Farming

Biofertilizers are considered natural and regenerative supplies. Just as Kodo Millet assists with long-lasting growth and nourishment for the body; biofertilizers assist with long-lasting soil health and crop productivity.

Reduce soil pollution and chemical build-up

• Increase biodiversity in the soil
• Increase water retention
• Improve long-lasting sustainable agriculture

Biofertilizer is particularly important for farmers in transition from chemical intensive agriculture to sustainable agriculture. Just as Kodo Millet helps reduce inflammation in the infant body, biofertilizers will help reduce swelling and stress on soil ecosystems. Farmers can responsibly cite and use natural amendments like liquid biofertilizer for higher yields and more importantly create healthier soil for future generations.

Types of Biofertilizers and Their Specific Applications

Biofertilizers are available in many kinds, and each one provides special benefits for crops, like different kinds of millets will provide different nutrients for babies.

They improve soil fertility, promote healthy roots and natural crop growth.

Here are the three major types of biofertilizers and how they help your plants.

Nitrogen-Fixing Biofertilizers

Nitrogen-fixing biofertilizers act as a natural source of protein to plants – supporting their overall growth in a strong, green, and healthy state. 

This type of BIOFERTILIZER contains beneficial bacteria that have the ability to transform atmospheric nitrogen, making it available for plants to uptake.  This allows plants to grow without relying solely on synthetic nitrogen fertilizers. 

Best Crops for Application:  

Legumes (pulses), groundnut, soybean, peas, and even cereals when applied correctly. 

How-to Apply Biofertilizer (Nitrogen Fixers): 

• Seed treatment: Seeds are mixed with a liquid biofertilizer and left to dry under shade. 
• Soil application: Added as close to root zone at sowing. 
• Root dipping: If seedlings are cropped before transplanting, this is an ideal way to apply. 

Phosphate-Solubilizing Biofertilizers

These work as gentle digestive aids for plants - facilitating their digestion of phosphorus - one of the critical nutrients for promoting healthy flowers and strong roots.

Phosphate-solubilizing bacteria (PSB) are capable of releasing organic acids that dissolve fixed phosphorus in the soil and make it plant available.

Benefits of PSB Biofertilizers:

• Increases root length and vigor
• Improves flowering and fruiting
• Prevents the symptoms of phosphorus deficiency

Beneficial in phosphorus deficient soils

Best Crops for use

Tomato, chili, wheat, paddy, maize, vegetables, fruit crops

Ways to Use Biofertilizers (PSB)

• Soil application: Mix with compost and ring it around the base of the plant
• Liquid biofertilizer spray: Apply a foliar spray for quick uptake.
• Seed treatment: Coat seeds prior to planting to give them an early confidence supply of roots.

Mycorrhizal Fungi and Their Role in Plant Growth

Mycorrhizal fungi provide a protective network for roots—assisting plants with the uptake of additional nutrients and water and enhancing their immunity.

They grow tiny extensions of roots (hyphae) that greatly increase the plant's area of absorption.

Benefits of Mycorrhizal Biofertilizers:

-Increases water-holding capacity in dry soils

-Increases nutrient uptake, especially phosphorus

-Enhances plant immunity and stress tolerance

-Aids roots to penetrate deeper into soil

Best Crops for Application:

Fruit trees, vegetables, grapes, flowers, plantation crops, wheat and sugarcane.

How to Apply Biofungal Fertilizers (Mycorrhiza):

-soil application by sprinkling granules near root zone

-seedling dip by soaking in liquid biofertilizer mix before planting

-application in a planting pit for trees and perennial crops

Step-by-Step Guide: How to Use Biofertilizers Effectively

Biofertilizers are available in various forms and provide different benefits for crops, similar to how different millets suit babies at different phases. Biofertilizers are gentle, natural, full of nutrients, beneficial to soil, root strength and plant growth. They can be added as a seed treatment, soil application and/or foliar spray, depending on how much food you want, and each method of adding biofertilizer brings its unique and positive implication to agricultural success.

Seed Treatment with Biofertilizers

Seed treatment can be like taking your baby to their first nutritious food—simple, gentle, and extraordinarily helpful for their early development. When seeds are coated with liquid biofertilizer, these will also introduce beneficial microbes right at germination.

Best For: Vegetable, cereal, pulse, oilseed, and fruit crops.

Soil Application Techniques

Certain millets are well suited for older babies requiring increased energy, just as bio-fertilizer for soil applying is best suited for crops requiring long-term nourishment. Bio-fertilizers applied into soil can keep feeding soil and crop for extended periods. 

Benefits of Soil Application:

• Increases the microbial activity of the soil;
• Enhances the availability of nutrients (N, P, K);
• Promotes greater root development and stabilization;

Simple Approaches:

• Basal Application: Mix the bio-fertilizer with compost and apply it before planting;
• Side Dressing: Apply it at the root zone during the growing period of the crop;
• Mix with Drip Irrigation: Put an appropriate bio-fertilized into drip water for even distribution.

Foliar Spray Application: Quick and Efficient

Foliar spray acts like an on-demand energy drink; it is fast, effective, and ideal for crops that need to recover quickly or require assistance with growth. Liquid biofertilizer is easily applied and absorbed by the leaves.

Why foliar spray works well:

• Nutrients are absorbed immediately.
• Assists plants in stress recovery (hot, dry, transplanting)
• Gives a boost to flowering and fruiting stages

How to apply:

• Mix biofertilizer with clean water (label dose).
• Spray either early in the morning or late in the evening.
• Always cover both sides of the leaves for the best results.

When to apply foliar spray:

• During flowering.
• Plant shows slow growth.
• Stress from bugs or diseases.

Best Practices for Maximizing Results with Biofertilizers

There are several different types of biofertilizers, and they all help plant health in different ways. It's just like how different millets help babies at different stages of growth. A biofertilizer will enhance the soil, assist with nutrient uptake, and cause crops to grow more vigorously and green, without stressing crops with heavy chemicals, when used correctly.  The proper use of these natural microbes will keep them alive, active, working hard for your farm.

What follows are the best practices for you to get the most out of every application of biofertilizer.

Ideal Conditions for Biofertilizer Use

Similar to how some millets are suitable for smaller babies and other for older babies, the same goes for biofertilizers: they perform under favorable conditions that are specific to them. Ensuring that these conditions are optimally in place, will enable the microbes to thrive and maximize the benefits.

a. Adequate Soil Moisture

• Biofertilizers thrive in moist soils - not too dry, not saturated. 
• Soil moisture accomplishes the following:
• Biological activity is initiated
• Beneficial microbes multiply and colonize the root zone
• Adequate moisture will ensure a slow release of nutrients for the plant
• Moist soil conditions are like having a comfortable "home" for the beneficial microbes.

b. Ideal Temperature Range

• Biofertilizers are especially sensitive to extreme hot conditions and cold conditions.
• Ideal temperature range: 20°C – 35°C.
• Extreme hot conditions will kill microbes.
• Cold conditions can slow or halt biological activity
• Just as babies need mild conditions to function, microbes need mild conditions to stay active as well.

c. Avoid Chemical Fertilizers & Pesticides Even After Application

• Strong fertilizers/pesticides will kill beneficial bacteria that is present in biofertilizers.
• Do not use a chemical pesticide for 7–10 days after applying a biofertilizer.
• Do not reduce use of urea/synthetic fertilizer towards the time of application.
• By doing this, beneficial microbes will have a better chance to establish itself within your soil.

Biofertilizer Dosage Recommendations

Just as feeding babies an appropriate amount of millet is important, the right biofertilizer must be applied: Not enough and there will be no response, and too much will waste resources and effort with no benefit. 

a. Seed Treatment Dosage

• Coated seeds of biofertilizer give plants a good start. 
• 200–250 g of biofertilizer for 10 kg of seeds
• You want it very uniformly coated for complete protection of the roots
• Works best with Rhizobium, Azospirillum & PSB
• Seed Treatment gets you a jump start of early and active rooting colonization. 

b. Soil Application Dosage

• Use for larger fields or garden beds.
• 4–6 kg of biofertilizer/acre
• Mix with compost at 20–25 kg (or spread separately) for even spread when putting down.
• Think about semi-dry, composted material to hold moisture and include all surface material. 
• Apply before watering for best absorption. 
• This makes the most sense in terms of healthy soil, plant options and longevity. 

c. Liquid Biofertilizer Dosage

• Liquid biofertilizer is the easiest to mix and spread and absorb.
• 2-4 ml/ liter of water.
• Spray during early morning or late evening hours when it is cooler. 
• For vegetables, fruits and leafy greens.
• The liquid form is ideal for stimulating a quick nutrient drink for the plants.

Storage Tips for Biofertilizers

Just like you should carefully store millets to preserve their nutrition, biofertilizers must be stored carefully to keep the microbes alive and active. Improperly stored products will lose effectiveness and harm subsequent crops. 

a. Keep Away from Heat & Direct Sunlight

Heat destroys beneficial microbes. 

Store in a cool, shady area

Do not store around stoves, near engines, or hot walls. 

Best storage temperature = 15°C - 25°C 

b. Use Airtight & Original Packaging

• Biofertilizers are very sensitive to air. 
• Always keep packets sealed tight to keep air out. 
• Don't let moisture enter the unopened pack as this compromises the product. 
• Do not put in metal containers. 
• Microbes have the best chance of thriving in a breathable container and the original packaging is best. 

c. Use Before Expiry

• Unlike chemical fertilizers which can last years, biofertilizers have a shorter shelf life. 
• Always check with the manufacturer for the manufacturing and expiry date. 
• Use biofertilizer in 6-12 months for best results. 
• Shake liquid biofertilizer very well before using.

Troubleshooting Common Issues When Using Biofertilizers

Similar to how some babies react differently to different varieties of mill, c r o p s may also respond differently to different types of biofertilizers. Although biofertilizers are natural and safe, farmers often have difficulty because application methods, storage and/or soil conditions are not ideal. Understanding these issues leads to better and more effective use of biofertilizers for healthier and greener crops.

Why Isn’t My Crop Responding to Biofertilizers?

At times, even when using a biofertilizer, we do not see visible improvement in crops, in the same way that a baby may not adapt to a new millet right away. There are often simple and easy solutions to these situations. 

Possible Reasons:

- The soil contains not enough moisture to activate the microbes

- The seed was contaminated with chemical pesticides before treatment 

- The biofertilizer was of poor quality or expired 

- Dosage and/or application was applied wrong/unevenly

Biofertilizers contain living microorganisms. These microscopic helpers need certain conditions that allow them to live and multiply. If there is not enough moisture, if it is too acidic, or if there are chemical residues in the soil, these little microorganisms can't do their work. Not even the best liquid biofertilizer will help if the soil environment doesn’t allow for those microbes to function. This is part of the reason why it is important to prepare the soil and insure the right amount of moisture is present - it is just as important as knowing how to use biofertilizers.

Common Problems with Biofertilizer Solutions

As different millets offer unique textures and digestibility for infants, different bio-fertilizers will all perform differently depending on differences in storage, temperature, and handling.

For those who don't remember, bio-fertilizers are usually not very effective with seed, especially if being pre-soaked or combined with fertilizer. 

To elaborate further:

The unique biological composition of a liquid bio-fertilizer should always be kept in cool, dark conditions because any extreme heat or prolonged sunlight can kill a big part of the beneficial microbes. Also, sometimes farmers will mix bio-fertilizers with chemical fertilizers or pesticides which can immediately destroy the biotic local culture and their efficacy. Just as you might store millets correctly to retain nutrient power, you need to store your bio-fertilizer properly to keep its microbial strength. 

Solutions for Poor Performance with Organic Fertilizers

If biofertilizers have not produced the desired outcomes, a few basic fixes can restore the biofertilizers to full potential—similar to changing types of millets based on how a baby digests food.

Solutions to Implement:

• Improve soil moisture before applying any biofertilizers
• Mix the biofertilizers with compost for increased microbial activity
• Avoid using a synthetic or chemical fertilizer 48 hours before and/or after applying biofertilizers
• Use new or fresh, high-quality biofertilizers only

Apply biofertilizers in the evening to protect the beneficial microbes from sunlight and preserve their use in the soil

For best crop response, apply the biofertilizers under moist soil conditions and when there is somewhat organic matter present (like compost). Organic compost-based fertilizers create a comfortable "home" for different microbes to thrive. Once processes and practices are in place to use biofertilizers properly—seed treatment, soil applications, or root dipping—you can maximize survivability of the beneficial microbes and microorganisms involved. Biofertilizers developed from organic manures, regardless, when applied properly, coupled with compost produces greener, larger, and healthier crops with strong immunity and greater yields.

The Environmental and Economic Benefits of Switching to Biofertilizers

Biofertilizers are offered in many different forms, and promise large benefits both for crops, soil, and ultimately, sustainable farming over time.

In fact, just as millets assist babies through several phases of growth, every type of biofertilizer assists plants, though in various unique and powerful ways, in terms of cost-savings, soil enrichment, and yields.

Consider these benefits explained in a manner that is understandable and relatable.

Cost Savings from Biofertilizers

Biofertilizers are one of the most economical inputs for farmers because a small amount goes a long way.

Why This Matters:

Like millets provide a lot of nutrition at a very economical cost during the winter, biofertilizers can provide great crop nutrition while reducing costs of farmer expenses year after year.

Sustainable Agriculture Advantages with Biofertilizers

Biofertilizers enrich the soil with beneficial microbes that support long-term sustainability.

• Increase soil biodiversity and natural microbial life.
• Reduce pollution caused by synthetic fertilizers.
• Improve soil structure, moisture retention, and long-term health.

Why It Matters:

Just as millets support healthy digestion for babies, biofertilizers support healthy soil that continues to nourish plants season after season.

Biofertilizers and Crop Yield: A Positive Impact

Plants treated with biofertilizers exhibit improved growth, deeper rooting, and greater resistance to diseases than plants that receive no biofertilizer. 

• Biofertilizers enhance nutrient uptake resulting in greater yields. 
• The flowering and fruiting of the plants were also improved. 
• The healthy roots resulted in better consistency when drought conditions existed, along with improved strength in the plants.

Why This Matters:

Like each variety of millet can contribute to various aspects of a baby’s growth, each type of biofertilizer contributes to a specific plant function. All of this results in planting and harvesting a stronger crop.
