What are common names of soil bacteria?
A teaspoon of productive soil generally contains between 100 million and 1 billion bacteria. They can be classified according to the functions they perform in soil and are: Nitrogen-fixing bacteria form symbiotic associations with the roots of legumes like clover and lupine, and trees such as alder and locust. Visible nodules are created where bacteria infect a growing root hair. The plant supplies simple carbon compounds to the bacteria, and the bacteria convert nitrogen (N2) from air into a form the plant host can use. When leaves or roots from the host plant decompose, soil nitrogen increases in the surrounding area. Nitrifying bacteria change ammonium (NH4+) to nitrite (NO2-) then to nitrate (NO3-) - a preferred form of nitrogen for grasses and most row crops. Nitrate is leached more easily from the soil, so some farmers use nitrification inhibitors to reduce the activity of one type of nitrifying bacteria. Nitrifying bacteria are suppressed in forest soils, so that most of the nitrogen remains as ammonium. Denitrifying bacteria convert nitrate to nitrogen (N2) or nitrous oxide (N2O) gas. Denitrifiers are anaerobic, meaning they are active where oxygen is absent, such as in saturated soils or inside soil aggregates. Actinomycetes are a large group of bacteria that grow as hyphae like fungi . They are responsible for the characteristically "earthy" smell of freshly turned, healthy soil. Actinomycetes decompose a wide array of substrates, but are especially important in degrading recalcitrant (hard-to-decompose) compounds, such as chitin and cellulose, and are active at high pH levels. Fungi are more important in degrading these compounds at low pH. A number of antibiotics are produced by actinomycetes such as Streptomyces.
What type of bond is aluminum nitrate?
ionic
What does the soil type CA mean?
"Soil type CA" sounds like it is an abbreviation for a soil type on a soil map. You will have to consult that soil map or the soil map's makers to find the answer to that question. If "soil type CA" did not come from a soil map, you will need to consult the source. There is no universally recognized soil type named "CA."
What is the type of soil in Lahore?
which type of soil is there in lahore
What is Raw soil?
A type of soil that is kind of purplish. A type of soil that is kind of purplish.
What are the functions of bacteria?
Bacteria and fungi are the type of decomposer they eat the dead and decaying plant and animal and convert it into humus which is useful for the soil as they increase the soil fertility and this nutrition is absorbed by plants.

How do soil microorganisms help to maintain a healthy soil or plant?
Microscopic actinomycetes are a type of bacteria that plays a healthy role in the soil. They decompose organic matter and create humus.
What is a decomposer in top soil?
Really any type of fungus or bacteria. for example mushrooms and worms are decomposers.
Which type of organism adds nutrients to the soil?
producers are the answers this is because ex. of producers are algea and bacteria.
What colour does soil turn on with pH paper?
Depending on the type of soil, the value of pH and the type of pH paper. For an acid soil the pH paper from Merck (art. 9565) this color will be probable green.
Give examples of three types of decomposers and describe their effects on soil?
First type of decomposer is bacteria. Most abundant decomposers. Bacteria produce methane as a by-product. Second type is fungi are the also efficient next to bacteria. They can decompose cellulose and other materials. Worms decompose dead organic material and mix it with the soil. Information by FIS' book Thanks!!
Where do bacteria fix nitrogen gas?
Bacteria fix nitrogen by taking the nitrogen in the air and turning it into a type of nitrogen that can be used by other organisms. This usually occurs in the form of ammonium.
What is the role prokaryotes play in nitrogen recycling?
1. Bacteria that nitrifies ammonium compounds in the soil (called "nitrifying bacteria"). Example: Nitrosomonas. 2. Bacteria that nitrifies nitrites (NO2-) in the soil (also called "nitrifying bacteria"). Example: Nitrobacter. 3. Bacteria that denitrifies nitrates (NO3-) in the soil (called "denitrifying bacteria"). Example: Pseudomonas denitrificans. 4. Bacteria that "fixes" nitrogen (called "nitrogen-fixing bacteria"). Examples: Rhizobium (which is symbiotic) and Azotobacter (which is free-living). 5. You also have bacteria that putrefies nitrogenous waste (like urea) and the protein in dead organisms. This type of bacteria is called putrefying bacteria.
Can granite turn into soil?
It can become a part of soil. Soil is a mixture of organic and mineral/rock components. Just about any rock type can contribute to the inorganic portion.
What type of nitrate is use for developing fingerprints on wood?
Silver nitrate
How do you describe five instances in the nitrogen cycle where bacterial action is important?
1. Bacteria that nitrifies ammonium compounds in the soil (called "nitrifying bacteria"). Example: Nitrosomonas. 2. Bacteria that nitrifies nitrites (NO2-) in the soil (also called "nitrifying bacteria"). Example: Nitrobacter. 3.
