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.
They proposed a definition of the microbiome based on a revival of the "compact, clear, and comprehensive description of the term" as originally provided by Whipps et al., but supplemented with two explanatory paragraphs, the first pronouncing the dynamic character of the microbiome, and the second clearly separating the term microbiota from ...
Soil biology is the study of microbial and faunal activity and ecology in soil. Soil life, soil biota, soil fauna, or edaphon is a collective term that encompasses all organisms that spend a significant portion of their life cycle within a soil profile, or at the soil-litter interface.
Nitrogen is an essential element needed for the creation of biomass and is usually seen as a limiting nutrient in agricultural systems. Though abundant in the atmosphere, the atmospheric form of nitrogen cannot be utilized by plants and must be transformed into a form that can be taken up directly by the plants; this problem is solved by biological nitrogen fixers.
The five-year project, best characterized as a feasibility study with a budget of $115 million, tested how changes in the human microbiome are associated with human health or disease. [85] The Earth Microbiome Project (EMP) is an initiative to collect natural samples and analyze the microbial community around the globe.
The plant microbiome, also known as the phytomicrobiome, plays roles in plant health and productivity and has received significant attention in recent years. [1] [2] The microbiome has been defined as "a characteristic microbial community occupying a reasonably well-defined habitat which has distinct physio-chemical properties.
The environment includes the soil, air, and climate. Examples of ecological areas are fields, rangelands, forests. [1] Knowledge of the interactions within a phytobiome can be used to create tools for agriculture, crop management, [2] increased health, preservation, productivity, and sustainability of cropping and forest systems.

Soil is made up of a multitude of physical, chemical, and biological entities, with many interactions occurring among them. It is a heterogenous mixture of minerals and organic matter with variations in moisture, temperature and nutrients.
