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. These organisms include earthworms, nematodes, protozoa, fungi, bacteria, different arthropods, as well as some reptiles (such as snakes ...
Soil carbon storage is an important function of terrestrial ecosystems. Soil contains more carbon than plants and the atmosphere combined. [1] Understanding what maintains the soil carbon pool is important to understand the current distribution of carbon on Earth, and how it will respond to environmental change.
As these organisms eat, grow, and move through the soil, they make it possible to have clean water, clean air, healthy plants, and moderated water flow. There are many ways that the soil food web is an integral part of landscape processes.
From the ancient time, people grow the leguminous crops to make the soil more fertile. And the reason for this is: the root of leguminous crops are symbiotic with the rhizobia (a kind of diazotroph). These rhizobia can be considered as a natural biofertilizer to provide available nitrogen in the soil.
Microorganisms like those that make up biological soil crust are good at responding quickly to changes in the environment even after a period of dormancy such as precipitation. Desiccation can lead to oxidation and the destruction of nutrients, amino acids, and cell membranes in the microorganisms that make up biological soil crust. [16]
Soil erosion occurs naturally, but human activities can greatly increase its severity. [28] Soil that is healthy is fertile and productive. [29] But soil erosion leads to a loss of topsoil, organic matter, and nutrients; it breaks down soil structure and decreases water storage capacity, reducing fertility and water availability to plant roots.
Fungi are abundant in soil, but bacteria are more abundant. Fungi are important in the soil as food sources for other, larger organisms, pathogens, beneficial symbiotic relationships with plants or other organisms and soil health. Fungi can be split into species based primarily on the size, shape and color of their reproductive spores, which ...
Soil respiration refers to the production of carbon dioxide when soil organisms respire. This includes respiration of plant roots , the rhizosphere , microbes and fauna . Soil respiration is a key ecosystem process that releases carbon from the soil in the form of CO 2 .
