The rate of decomposition is governed by three sets of factors: the physical environment (temperature, moisture and soil properties), the quantity and quality of the dead material available to decomposers, and the nature of the microbial community itself. [64] Decomposition rates are low under very wet or very dry conditions.
Soil organic matter (SOM) is the organic matter component of soil, consisting of plant and animal detritus at various stages of decomposition, cells and tissues of soil microbes, and substances that soil microbes synthesize.
In soil science, mineralization is the decomposition (i.e., oxidation) of the chemical compounds in organic matter, by which the nutrients in those compounds are released in soluble inorganic forms that may be available to plants. [1] [2] Mineralization is the opposite of immobilization.
Decomposition microbiology can be divided into two fields of interest, namely the decomposition of plant materials and the decomposition of cadavers and carcasses. The decomposition of plant materials is commonly studied in order to understand the cycling of carbon within a given environment and to understand the subsequent impacts on soil ...
Soil formation, also known as pedogenesis, ... Chemical decomposition and structural changes result when minerals are made soluble by water or are changed in ...
They're commonly used as mulch to suppress weeds, improve water retention, and reduce soil erosion. ... "The ratio of carbon to nitrogen drives the decomposition process, so balancing the presence ...
Soil chemistry is the study of the chemical characteristics of soil.Soil chemistry is affected by mineral composition, organic matter and environmental factors. In the early 1870s a consulting chemist to the Royal Agricultural Society in England, named J. Thomas Way, performed many experiments on how soils exchange ions, and is considered the father of soil chemistry. [1]
Turnover of mycorrhizal biomass into the soil carbon pool is thought to be rapid [7] and has been shown in some ecosystems to be the dominant pathway by which living carbon enters the soil carbon pool. [8] Outlined below are the leading lines of evidence for how different aspects of mycorrhizal fungi may alter soil carbon decomposition and storage.
