A pinch of soil can contain billions to trillions of bacteria, depending on factors like soil type, location, and environmental conditions. It is estimated that a gram of soil can contain anywhere from 100 million to 1 billion bacteria.
Streptomycetes bacteria present in the dry worm soil, release compounds such as geosmin and 2-methyl isodorneol. note- 3/4 million of them are present in a pinch of soil.
Soil bacteria are not responsible for fixing nitrogen from the atmosphere. This process is carried out by nitrogen-fixing bacteria like Rhizobium and cyanobacteria.
Soil bacteria change ammonia into nitrite and nitrate through a process called nitrification.
Bacteria in the soil play a crucial role in nutrient cycling by breaking down organic matter and making nutrients available to plants. They also help to decompose dead organisms, contributing to the overall health of the ecosystem. Additionally, soil bacteria can help to suppress plant pathogens and promote plant growth through interactions with plant roots.
Bacteria play a critical role in soil health by breaking down organic matter, releasing nutrients that plants can use for growth. They also help improve soil structure and create a more hospitable environment for other soil organisms to thrive. Some types of bacteria can also fix nitrogen from the atmosphere, making it available to plants.

There can be billions to trillions of bacteria in 1 gram of sandy soil, depending on various factors such as soil composition, moisture content, and nutrient availability. Bacteria play a crucial role in soil health and ecosystem functioning.

Approx 89.3 million of them.
reasearchers have found 4000 different types of bacteria in 1 gram of soil. Their are about 5*1030 numbers of bacteria on this planet
(i) De composer bacteria help in decomposing matter in the soil. (ii) It helps to maintain fertility in soil. (iii) Bacteria like cyanobacteria help in nitrogen fixation.
Bacteria are typically more plentiful in soil than in water. However, both water and soil can contain vast populations of bacteria. In water, bacteria tend to be found in higher concentrations near the surface and in areas with organic matter accumulation, while in soil, they can be present in diverse ecosystems throughout.
There are many decomposers in the estuaries of rivers. The majority of these are different types of bacteria and fungi. They enrich the water and soil with recycled organic matter.
Denitrofying bacteria help to metabolize nitrogen so that they can use the it. These bacteria take available nitrogen from the soil, as opposed to nitrifying bacteria that increase available nitrogen in the soil.
