What is Biofertilizer?

Biofertilizers are the compound that contains germs, which helps in advertising the development of plants and also trees by enhancing the supply of necessary nutrients to the plants. It comprises living organisms that include mycorrhizal fungis, green algae, and microorganisms. Mycorrhizal fungis preferentially withdraw minerals from raw material for the plant whereas cyanobacteria are defined by the property of nitrogen fixation.

Nitrogen fixation is specified as a procedure of transforming the di-nitrogen particles into nitrogen compounds. For instance, some germs transform insoluble kinds of soil phosphorus right into soluble kinds. Therefore, phosphorus will be available for plants.

Also, review Nitrogen Addiction and also Nitrogen Metabolism

Types of Biofertilizers

Adhering to are the vital sorts of biofertilizers:

Symbiotic Nitrogen-Fixing Bacteria

Rhizobium is among the vital cooperative nitrogen-fixing microorganisms. Below bacteria look for sanctuary and get food from plants. In return, they help by offering fixed nitrogen to the plants.

Loose Organization of Nitrogen-Fixing Microorganisms

Azospirillum is a nitrogen-fixing germs that live around the roots of higher plants yet do not create an intimate partnership with plants. It is commonly described as rhizosphere association as this germs collect plant exudate as well as the same is used as a food by them. This process is described as associative mutualism.

Symbiotic Nitrogen-Fixing Cyanobacteria

Blue-Green algae or Cyanobacteria from the symbiotic organization with numerous plants. Liverworts, cycad roots, brush, as well as lichens are some of the Nitrogen-fixing cyanobacteria. Anabaena is discovered at the fallen leave dental caries of the brush. It is in charge of nitrogen fixation. The fern plants decay as well as launch the same for usage of the rice plants. Azolla pinnate is a brush that resides in rice areas but they do not control the growth of the plant.

Free-Living Nitrogen-Fixing Germs

They are free-living soil microorganisms which do nitrogen fixation. They are saprotrophic anaerobes such as Clostridium beijerinckii, Azotobacter, etc

. Among all the types of biofertilizers, Rhizobium as well as Azospirillum are most widely utilized.

Parts of Biofertilizers

The components of biofertilizers include:

Biography Compost

It is one of the environmentally friendly product made up of waste material launched from sugar sectors which are decayed. It is magnified with human-friendly microorganisms, fungi, and also numerous plants.


It is a green as well as nonpathogenic product used in a range of plants in addition to in gardening and also decorative plants, such as paddy apple, sugar cane, brinjal, corn, cotton, vegetables, citrus, etc. It works as an efficient destroyer and hostile hyper parasitical versus eggs of a number of bores, shoot, fruit, leaves, blossom eaters as well as various other pathogens in the field.


It protects the origins from pathogens present in the dirt and also plays an essential function in fixing the climatic nitrogen. Nitrogen is an extremely crucial nutrient for the plant as well as concerning 78% of the total atmosphere consists of nitrogen.


Phosphorus is just one of the necessary nutrients for plants growth as well as development. Phosphate solubilizing microbes, hydrolyze insoluble phosphorus compounds to the soluble type for uptake by plants. Many fungi and also microorganisms are used for the function such as Penicillium, Aspergillus, Bacillus, Pseudomonas, and so on


Vermicompost It is an Environmentally friendly natural plant food includes vitamins, hormones, natural carbon, sulfur, antibiotics that aid to boost the quantity and also top quality of return. Vermicompost is one of the quick fixes to enhance the fertility of the soil.

Value of Biofertilizers are very important for the complying with factors: Biofertilizers improve soil texture and yield of plants.

They do not enable microorganisms to prosper.

They are environment-friendly as well as cost-effective.

Biofertilizers protect the atmosphere from pollutants given that they are natural plant foods.

They destroy numerous damaging substances present in the soil that can cause plant diseases.

Biofertilizers are proved to be effective also under semi-arid conditions.

Applications of Biofertilizers Following are the essential applications of biofertilizers: Seedling origin dip This approach applies to rice plants. The seedlings are planted in the bed of water for 8-10 hours.

Seed Treatment The seeds are dipped in the mixture of nitrogen and phosphorus plant foods. These seeds are then dried and also sown immediately.

Dirt Therapy The biofertilizers along with the compost plant foods are mixed as well as kept for one evening. This mixture is then spread out on the soil where the seeds have to be planted.

Frequently Asked Questions on Biofertilizers What do you understand by biofertilizers?

Biofertilizers are materials which contain microorganisms, which when added to the dirt enhances the plant return and also promotes plant growth.

What are the advantages of biofertilizers over chemical plant foods?

Biofertilizers are cost-effective.

They minimize the threat of plant diseases.

The health of individuals taking in the vegetables grown by the addition of chemical plant foods is a lot more in danger.

Biofertilizers do not cause any kind of kind of air pollution.

What is the requirement of using biofertilizers?

Biofertilizers are needed to recover the fertility of the dirt. Long term use of chemical plant foods weakens the dirt and affects the plant return. Biofertilizers, on the other hand, boost the water holding ability of the soil and also add crucial nutrients such as nitrogen, vitamins as well as healthy proteins to the soil. They are the natural type of plant foods as well as for this reason, extensively used in agriculture.

Call a few bacteria used as biofertilizers.

Bacterium made use of as biofertilizers are: Rhizobium Azotobacter Azospirilium Just how do biofertilizers advertise plant growth?

Biofertilizers use specific microbes. These microbes trap atmospheric nitrogen and convert it into nitrates and nitrites and also make it available to the plants. They likewise transform insoluble phosphates into the kinds required by the plants.

What are the major sources of biofertilizers?

The main sources of biofertilizers consist of bacteria, cyanobacteria as well as fungis.

Call a crucial nitrogen-fixing germs.

Rhizobium is a vital nitrogen-fixing bacteria. Rhizobium stays in symbiotic organization with the leguminous plants, specifically in their origin blemishes. It traps the atmospheric nitrogen and converts it right into usable kinds that improve the development of the plants.
