Soil microbiology is the study of microorganisms in soil, their functions, and how they affect soil properties. [1] It is believed that between two and four billion years ago, the first ancient bacteria and microorganisms came about on Earth's oceans.
The soil is home to a large proportion of the world's biodiversity.The links between soil organisms and soil functions are complex. The interconnectedness and complexity of this soil 'food web' means any appraisal of soil function must necessarily take into account interactions with the living communities that exist within the soil.
Microbes are essential tools in biology as model organisms and have been put to use in biological warfare and bioterrorism. Microbes are a vital component of fertile soil. In the human body, microorganisms make up the human microbiota, including the essential gut flora.
[7] [8] [9] Microorganisms (soil microbes) are involved in biogeochemical cycles in the soil which helps in fixing nutrients, such as nitrogen, phosphorus and sulphur in the soil (environment). [10] As a consequence of the quantitative magnitude of microbial life (calculated as 5.0 × 10 30 cells, [ 11 ] [ 12 ] ) microbes, by virtue of their ...
These microorganisms consist of naturally occurring microbes, such as photosynthesizing bacteria, lactic acid bacteria, yeasts, and fermenting fungi, which can be applied to increase soil microbial diversity. The application of effective microorganisms improves soil structure and fertility while significantly boosting biological diversity.
Human composting turns bodies into soil by speeding up “what happens on the forest floor,” according to Tom ... it creates perfect conditions for microbes to break the body down at a molecular ...
[40] One feature of soil microbes is spatial separation which influences microbe to microbe interactions and ecosystem functioning in the soil habitat. [41] Microorganisms in soil are found to be concentrated in specific sites called 'hot spots' which is characterized by an abundance of resources such as moisture or nutrients.
The root microbiome (also called rhizosphere microbiome) is the dynamic community of microorganisms associated with plant roots. [1] Because they are rich in a variety of carbon compounds, plant roots provide unique environments for a diverse assemblage of soil microorganisms, including bacteria, fungi, and archaea.
