What is biofertilizers and its classification?

Biofertilizers are substance that contains microbes, which helps in promoting the growth of plants and trees by increasing the supply of essential nutrients to the plants. It comprises living organisms which include mycorrhizal fungi, blue-green algae, and bacteria.

What are the types of biofertilizers?

Based on type of microorganism, the bio-fertilizer can also be classified as follows: Bacterial Biofertilizers: e.g. Rhizobium, Azospirilium, Azotobacter, Phosphobacteria. Fungal Biofertilizers: e.g. Mycorhiza. Algal Biofertilizers: e.g. Blue Green Algae (BGA) and Azolla.

What is the Hindi meaning of biofertilizers?

What is biofertilizers PDF?

• Biofertilizer contains microorganisms which promote the adequate supply of nutrients to the host plants. and ensure their proper development of growth and regulation in their physiology. • They help in increasing the crop yield by 10-25%.

What is the example of biofertilizer?

Biofertilizers such as Rhizobium, Azotobacter, Azospirilium and blue green algae (BGA) have been in use a long time. Rhizobium inoculant is used for leguminous crops. Azotobacter can be used with crops like wheat, maize, mustard, cotton, potato and other vegetable crops.

What are biofertilizers give five examples?

There are five biofertilizers viz. Rhizobium, Azotobacter, Azospirillum, Phosphate Solubilizing Bacteria and mycorrhiza , which have been incorporated in India’s Fertilizer Control Order (FCO), 1985. Rhizobium, Azotobacter, Azospirillum and blue green algae(BGA) have been traditionally used as Biofertilizers.

What is biofertilizer function?

Biofertilizers utilize microorganisms and materials that stimulate the natural processes in the soil. These processes affect plant growth and development. So, biofertilizers indirectly improve plant growth by enhancing the biological processes through microorganisms.

What is the importance of biofertilizers?

Biofertilizers are biological preparations of efficient microorganisms that promote plant growth by improving nutrient acquisition. They enhance soil productivity by fixing atmospheric nitrogen, solubilizing soil phosphorus, and stimulating plant growth.

What are the main sources of biofertilizers?

The main sources of biofertilizers are bacteria, fungi, and cynobacteria (blue-green algae). The most striking relationship that these have with plants is symbiosis, in which the partners derive benefits from each other.

What is biofertilizers write their two types?

Definition : The biofertilizers are mostly nitrogen-fixing microbes which enrich soil with nutrients. Mycorrhiza is a fungus. It forms symbiotic association with the roots of higher plants. There are two types ; Ectomycorrhiza, Endomycorrhiza.

What are the main sources of biofertilizers?

The main sources of biofertilizers are bacteria, fungi, and cynobacteria (blue-green algae). The most striking relationship that these have with plants is symbiosis, in which the partners derive benefits from each other.

What are bio fertilizers Class 12?

– Biofertilizers are those fertilizers that contain microbes which are used for promoting the growth of plants. This is done by increasing the supply of nutrients that are essential for the growth of plants. The microbes that are used in biofertilizers can be bacteria, some blue green algae and mycorrhizal fungi.

What is biofertilizer in agriculture?

Biofertilizers are living microbes that enhance plant nutrition by either by mobilizing or increasing nutrient availability in soils. Various microbial taxa including beneficial bacteria and fungi are currently used as biofertilizers, as they successfully colonize the rhizosphere, rhizoplane or root interior.

What is the importance of biofertilizers?

Biofertilizers are biological preparations of efficient microorganisms that promote plant growth by improving nutrient acquisition. They enhance soil productivity by fixing atmospheric nitrogen, solubilizing soil phosphorus, and stimulating plant growth.

Who discovered biofertilizers?

The commercial history of biofertilizers began with the launch of ‘Nitragin’ by Nobbe and Hiltner, a laboratory culture of Rhizobia in 1895, followed by the discovery of Azotobacter and then the blue green algae and a host of other micro-organisms.
