In video games using procedural world generation, the map seed is a (relatively) short number or text string which is used to procedurally create the game world ("map"). "). This means that while the seed-unique generated map may be many megabytes in size (often generated incrementally and virtually unlimited in potential size), it is possible to reset to the unmodified map, or the unmodified ...
The soil seed bank is the natural storage of seeds, often dormant, within the soil of most ecosystems. [1] ... [18] However, few species exceed 100 years. [19]
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.

Chernozem (/ ˈ tʃ ɜːr n ə z ɛ m / CHUR-nə-zem), [a] also called black soil, regur soil or black cotton soil, is a black-colored soil containing a high percentage of humus [3] (4% to 16%) and high percentages of phosphorus and ammonia compounds. [4] Chernozem is very fertile soil and can produce high agricultural yields with its high ...
In soil science, soil gradation is a classification of a coarse-grained soil that ranks the soil based on the different particle sizes contained in the soil. [1] Soil gradation is an important aspect of soil mechanics and geotechnical engineering because it is an indicator of other engineering properties such as compressibility , shear strength ...
The length of the fruit capsule varies from 2 to 3 cm (0.79 to 1.18 in), its width varies between 0.6 and 1.2 cm (0.24 and 0.47 in); there are four locules. The seeds are either white or black. [21] Sesame seeds are small. Their sizes vary widely by cultivar. Typically, the seeds are 3 to 4×2×1 mm (0.12 to 0.16×0.08×0.04 in).
A flowerpot filled with potting soil. Potting soil or growing media, also known as potting mix or potting compost (UK), is a substrate used to grow plants in containers. The first recorded use of the term is from an 1861 issue of the American Agriculturist. [1] Despite its name, little or no soil is usually used in potting soil.
