For many years, Biofertilizers have been an excellent form of natural fertilizer rich in Microorganisms. They were developed as a way to support Organic Production methods. The main types of Microorganisms in Biofertilizers are Nitrogen-fixing Bacteria, Phosphate-Solubilizing Microorganisms, and Beneficial Fungi. The benefits of using Biofertilizers include Improving Soil Fertility, Allowing Plants to Absorb Nutrients More Easily, and Providing Farmers with a Healthier and Chemical-Free Method to Feed Crops. Some examples of Microorganisms used in Biofertilizer Applications include Rhizobium (Nitrogen Fixing Bacteria), Mycorrhizal (Fungi that Create Fungal Networks or Webs), and Phosphorus Solubilizing Bacteria. Each application of a Biofertilizer is loaded with natural nutrients and actives that enhance the fertility of the soils that they are applied to and promote Sustainable Agriculture into the Future.

Understanding Biofertilizers: Definition and Types

Biofertilizers are very diverse with many different forms of microbes and they provide numerous benefits to crops by improving their health, as well as naturally enriching the soil, increasing the availability of nutrients and supporting plant development throughout various stages of the plant's life cycle. They have very little negative impact on the environment, are simple to apply, and provide great potential for increasing soil fertility over time.

What Are Biofertilizers?

Biofertilizers are natural, microbe-based fertilizers that supply essential nutrients to plants 

by increasing biological activity in the soil.

• They promote healthy root development.
• Improve soil aeration and nutrient cycling.
• Act as eco-friendly alternatives to chemical fertilizers.

Their natural mode of action makes them suitable for sustainable and organic farming systems

Types of Biofertilizers Used in Agriculture

Different types of biofertilizers cater to the specific needs of different crops, 

1. Nitrogen-Fixing Biofertilizers

• Rhizobium, Azotobacter, and Azospirillum convert nitrogen from the atmosphere to a form that is usable by plants. They encourage leafy growth and increase chlorophyll levels.

2. Phosphate Solubilizing Biofertilizers

• These types of microbes solubilize phosphorus that is not available, enabling crops to access the phosphorus they need. Natural support for the flowering and fruiting stages of plant development.

3. Mycorrhizal Fungi Biofertilizers

• The mycorrhizae increase the surface area of the roots and therefore increase the amount of water that can be taken up, as well as the amount of stress that can be tolerated by the plant.

These are ideal for horticulture, vegetables and fruit crops. All three types of biofertilizers serve to strengthen soils, which translates into improved plant growth and productivity.

Organic Fertilizers vs Biofertilizers

Organic fertilizers supply nutrients directly through decomposed matter, whereas biofertilizers help plants access nutrients already present in soil.

Key Differences:

Biofertilizers work best when used together with organic fertilizers to ensure both nutrition and soil health.

The Role of Biofertilizers in Enhancing Soil Health

Biofertilizers are considered natural healers of soils because they rebuild the fertility of soils, promote microbial life, and create a framework for ongoing, continuous productivity of soils. Through continual application of biofertilizers, degraded soils can be converted into environments that are capable of growing crops that are both high in nutrients and productive over the long term.

Improving Soil Fertility and Structure

• Biofertilizers promote soil structure and texture improvement through the release of enzymes that create a softer, richer and more fertile environment in which to grow crops. 
• Biofertilizers provide natural ways for crops to grow by providing additional nutrients to soil through the natural breakdown of organic matter.
• Biofertilizers bind together particles of soil to create a better structure for the growth of crops.
• Biofertilizers improve the ability of soils to retain water and provide adequate aeration for crops.

Enhancing the Soil Microbiome

The health of healthy soils depends on having a balance of different types of microorganisms. Biofertilizers assist in restoring the balance of moisture, organic matter and other nutrients that are essential for the growth of crops.

• Biofertilizers increase the population of beneficial microbial organisms.
• Biofertilizers provide a layer of competition to harmful pathogens that can reduce the yield of crops.
• Biofertilizers improve the processes involved with nutrient cycling by utilising the process of Nitrogen Fixation and the Solubilising of Phosphorus.

Long-Term Soil Sustainability 

• Biofertilizers reduce the dependency of farmers on synthetic chemical fertilisers.
• Biofertilizers help to prevent the degradation of soils and the loss of nutrients from soils.
• Biofertilizers promote an environment-friendly system of farming.
• Continued use of biofertilizers builds resilient soils that will support the production of high-yielding, high-quality crops for many years.
