Soil organic carbon organic carbon that does not meet the diagnostic criteria of artefacts. The classification comprises two levels: The first level has 32 Reference Soil Groups (RSGs). At the second level, for further differentiation a set of qualifiers is added to the name of the RSG. There are 202 qualifiers in total.
In an opportunity cropping system, crops are grown when soil water is adequate and there is a reliable sowing window. This form of cropping system is likely to produce better soil cover than a rigid crop rotation because crops are only sown under optimal conditions, whereas rigid systems are not necessarily sown in the best conditions available ...
Rye (Secale cereale) is a grass grown extensively as a grain, a cover crop and a forage crop. It is grown principally in an area from Eastern and Northern Europe into Russia. It is much more tolerant of cold weather and poor soil than other cereals, making it useful in those regions; its vigorous growth suppresses weeds and provides abundant forage for animals early in the yea
The soil of the latter area was more attractive to settlers because of it was made of rich, black-earth (chernozem), much more conducive to farming than the other poor Siberian soil types. A few decades later, the Upper Lena and Upper Angara River Basins became the site for agriculture, mainly rye, oats, and barley. These areas were more remote ...
A federal judge in New York granted the 19 states suing over DOGE's access to highly sensitive taxpayer records a temporary restraining order. Judge Paul Engelmayer wrote that the court believed ...
Soil bulk density, when determined at standardized moisture conditions, is an estimate of soil compaction. [3] 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 scientists use the capital letters O, A, B, C, and E to identify the master horizons, and lowercase letters for distinctions of these horizons. Most soils have three major horizons—the surface horizon (A), the subsoil (B), and the substratum (C). Some soils have an organic horizon (O) on the surface, but this horizon can also be buried.
