Question

what is the general name given to micro organisms that are added to the soil to from B from A​

Answer 1

Concept introduction:

A microorganism, sometimes known as a microbe, is a microscopic organism that can exist as a single cell or as a colony of cells.

Explanation:

We need to find the solution to the question.

A question has been provided to us.

Nitrogen-fixing soil bacteria (Azotobacter, Rhizobium), nitrogen-fixing cyanobacteria (Anabaena), phosphate-solubilizing bacteria (Pseudomonas sp.), and AM fungus are some of the most regularly utilised bio fertilisers.

Final answer:

Hence the final answers of the question are-

Azotobacter, Rhizobium, Anabaena etc.

Answer 2

Answer:

Biofertilizers are the general name given to microorganisms that are added to the soil to increase the nutrient quality of the soil.

Explanation:

• Biofertilizers are microorganisms that improve the nutritional quality of the soil.
• Some of the helpful microorganisms that contribute to the soil's increased fertility include bacteria, fungus, and algae.

Classification of Biofertilizers

• Nitrogen-fixing bacteria that are free-living, such as Azotobacter and Rhodospirillum.
• Nitrogen-fixing Cyanobacteria such as Anabaena and Nostoc.
• A loose association of nitrogen-fixing bacteria such as Azospirillum.
• Nitrogen-fixing bacteria that coexist, such as Rhizobium and Frankia

Microbes As Biofertilizers

The following microorganisms are used as biofertilizers:

• Rhizobium: They form root nodules and fix atmospheric nitrogen into an organic form in legume plants. Rhizobium enhances the quality, nutrient content, and plant development while having no adverse effects on the soil's quality.
• Azotobacter: These nitrogen fixers, which are free-living, are present in all varieties of upland crops. In addition to fixing nitrogen, they also give plant-specific antibiotics and growth agents.
• Azospirillum: These may be employed in wetland environments, unlike Azotobacter. They are non-free-living and are found inside the roots of plants, where they fix nitrogen from the air.
• Blue-green algae: Blue-green algae are nitrogen-fixing Cyanobacteria that can only be found in damp and marshy environments. A soil that is too acidic will not support them.
• Mycorrhiza: Mycorrhiza is the name for the symbiotic relationship that exists between fungus and plant roots. In order to bind the soil together and increase the activity of the bacteria, the mycorrhizal fungi are crucial. The water and nutrients the fungus extract from the soil help the plants grow more productively. Additionally, it makes the plant more resistant to environmental stresses.

Importance of Biofertilizers

• Biofertilizers are non-toxic to the environment and beneficial to the ecosystem.
• These raise the quality of the soil, which increases plant productivity.
• When necessary, farmers can create the inoculum of these microbes and provide them through injection into the plants.
• In the soil, they create compounds that encourage development.
• In semi-arid regions, biofertilizers can also be used.
