Up to 10 billion bacterial cells inhabit each gram of soil in and around plant roots, a region known as the rhizosphere. In 2011, a team detected more than 33,000 bacterial and archaeal species on sugar beet roots. [8] The composition of the rhizobiome can change rapidly in response to changes in the surrounding environment.
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.
Soil develops through a series of changes. [2] The starting point is weathering of freshly accumulated parent material.A variety of soil microbes (bacteria, archaea, fungi) feed on simple compounds released by weathering and produce organic acids and specialized proteins which contribute in turn to mineral weathering.

Several Hollywood stars, including Jelly Roll, Jessica Simpson and Kathy Bates, showed off dramatic transformations in 2024 after dropping 100 pounds during their weight-loss journey.
Soil regeneration is the reformation of degraded soil through biological, chemical, and or physical processes. [ 2 ] When productivity declined in the low-clay soils of northern Thailand, farmers initially responded by adding organic matter from termite mounds , but this was unsustainable in the long-term.
