Top 5 Bio-fertilizers in India: A Complete Guide for Farmers.

In India, agriculture plays a very important role. Because a huge number of people depend on farming for their livelihoods.  For large crop production, farmers want to improve soil fertility and use different fertilizers.

In recent years, farmers have faced a decrease in crop production. One of the main reasons is in decrease soil fertility. Because of the continuous use of chemical fertilizers, the soil weakens its nutrients. For this reason, the plants become weak and decrease the overall production.

In some cases, excessive use of chemical fertilizers can cause harm to human health and the environment.

What are Bio-fertilizers?

A bio-fertilizer is a type of natural fertilizer that contains living microorganisms ( like Bacteria and Fungi). These microorganisms help plants to absorb nutrients from the soil. In simple words, biofertilizers naturally improve soil fertility and then improve the plant’s growth.

How Bio-fertilizers work–

1. Bio-fertilizer make soil more fertile and support the growth of the plants.

2. Bio-fertilizers Infiltrate into the soil and provide microorganisms to plants, and help them to grow faster. 

3. Bio-fertilizer improve the soil health and make the environment safe and healthy.

Type of bio-fertilizers

There are many types of biofertilizers used in farming. These fertilizers mainly depend on microorganisms (bacteria and fungi), which help to provide nutrients.

1. Nitrogen Fixing Biofertilizers

 These fertilizers take nitrogen from the air and add it to the soil, so plants can grow better.

Examples: Rhizobium, Azotobacter, Azospirillum.

Nitrogen-fixing Biofertilizer naturally improves soil fertility. And with the help of using these nitrogen fertilizers, farmers can reduce their dependence on chemical fertilizers. They maintain the long-term soil health and protect the environment from harm.

Different crops need different types of nitrogen fertilizers. Rhizobium mostly grows on legume crops such as Peas, beans, and soybeans.

Benefits of Nitrogen Fixing Biofertilizers

1. It provides nutrients to the plants.

2. Improves plant health, and plants grow faster.

3. Increase the crop production.

4. improve the soil fertility.

2. Phosphate Solubilizing Bio-fertilizers (PSB)

Phosphate Solubilizing bio-fertilizer, which is called (PSB) for short, plays an important role in the field of agriculture. Phosphate Solubilizer is a nutrient essential for plants. These nutrients help in the development of plants' roots, energy transfer, and the formation of flowers and fruits.

But the problem is that even if phosphate is present in the soil, the plant cannot absorb it directly.

In agriculture, commonly used phosphates in microorganisms are (Bacillus, Pseudomonas, and some fungi species.

Benefits of Phosphate Solubilizing Bio-fertilizers (PSB)

1. Provide Better plant growth.

2. Make roots stronger. 

3. Increases the crop yield.

4. Decrease the use of chemical fertilizers.

3. Potassium Solubilizing Bio-fertilizers

This is a type of beneficial fungus that can work with plant roots. They can help plants absorb water and nutrients. It means that fungi and plants both help each other. With the help of special bacteria, this fertilizer converts potassium into a soluble form so that the plant can use it easily.

 Benefits of Potassium Solubilizing Bio-fertilizers

1.  Plants should grow in a healthy and faster way.

2.  Increase in plant diseases and resistance.

3.  Maintain soil fertility for a long time.

4. Blue Green Algae

Blue-green algae is a natural bio-fertilizer that is mainly used in paddy (Rice) fields.

It is a small microorganism known as cyanobacteria. They grew into the water and soaked into the mud, and provided nutrients to the plant.

Blue-green algae take nitrogen from the air and convert it into a form useful to plants.

Benefits of blue-green algae

1. Blue-green algae improve soil fertility by adding nitrogen to the soil.

2. Less use of chemical fertilizer

3. Increase the quality and quantity of crops.

4. They improve plant health.

5. Mycorrhiza ( Fungal Biofertilizer)

 

Mycorrhiza is a beneficial fungus that works together with the roots. It helps plants to absorb water from the soil and grow around the roots.

Because of this fungus, the plant’s roots become stronger, and they grow faster and healthier. Mycorrhiza especially helps phosphorus uptake by plants.

Benefits of Mycorrhiza ( Fungal Biofertilizer)

1. It makes the plant’s roots healthier and stronger.

2. It increases the ability to absorb nutrients and water.

3. It increases crop yield, thereby increasing crop productivity.

4. It improves soil fertility naturally.

Why Farmers Are Choosing Bio-fertilizers Instead of Chemical Fertilizers

In today’s life, most farmers use bio-fertilizers instead of chemical fertilizers.

Because biofertilizers improve soil health and protect our environment from harm, and keep it safe and beneficial for future generations.

On the other hand with chemical fertilizers, we can grow crops faster, but if we continue to use chemical fertilizers, they make the soil weak and reduce its natural fertility

Bio-fertilizer improves plant growth naturally, making roots stronger and maintaining soil fertility for a long time. That’s why farmers are shifted for sustainable and eco-friendly farming methods

Conclusion

 In today’s time, India’s future agriculture depends on its soil health. In the future, farmers will totally depend on chemical fertilizers for crop production, and the natural fertility of crops will be lost.Bio-fertilizers contain beneficial microorganisms (bacteria and fungi). They help soil to absorb nutrients, which is beneficial for plants. Bio-fertilizers are environmentally friendly. This is the most important aspect of bio-fertilizers.
