The biological soil crust is an integral part of many arid and semi-arid ecosystems as an essential contributor to conditions such as dust control, water acquisition, and contributors of soil nutrients. Biocrust is poikilohydric and does not have the ability to maintain or regulate its own water retention. [ 12 ]
Website. weber.edu. Weber State University (pronounced / ˈwiːbər / WEE-bər) is a public university in Ogden, Utah, United States. It was founded in 1889 as Weber Stake Academy and earned its current name in 1991. As of fall 2023, the student population reached 30,536 students, consisting of 16,020 undergraduate students, 1,002 graduate ...
Climate also indirectly influences soil formation through the effects of vegetation cover and biological activity, which modify the rates of chemical reactions in the soil. [43] Climate is the dominant factor in soil formation, and soils show the distinctive characteristics of the climate zones in which they form, with a feedback to climate ...
Temperature controlled furnace. Loss on ignition (LOI) is a test used in inorganic analytical chemistry and soil science, particularly in the analysis of minerals and the chemical makeup of soil. It consists of strongly heating ("igniting") a sample of the material at a specified temperature, allowing volatile substances to escape, until its ...
Soil bulk density, when determined at standardized moisture conditions, is an estimate of soil compaction. [60] Soil porosity consists of the void part of the soil volume and is occupied by gases or water. Soil consistency is the ability of soil materials to stick together. Soil temperature and colour are self-defining.
Soil moisture is the water content of the soil. It can be expressed in terms of volume or weight. Soil moisture measurement can be based on in situ probes (e.g., capacitance probes, neutron probes) or remote sensing methods. [ 1 ][ 2 ] Water that enters a field is removed from a field by runoff, drainage, evaporation or transpiration. [ 3 ...
Soil ecology is the study of the interactions among soil organisms, and between biotic and abiotic aspects of the soil environment. [1] It is particularly concerned with the cycling of nutrients , formation and stabilization of the pore structure , the spread and vitality of pathogens , and the biodiversity of this rich biological community .
University of Missouri, University of California, Berkeley. Doctoral advisor. Georg Wiegner. Hans Jenny (7 February 1899 [1] – 9 January 1992 [2]) was a Swiss-born soil scientist and expert on pedology (the study of soil in its natural environment), particularly the processes of soil formation. He served as 1949 President of the Soil Science ...
