Pork cycle. A schematic diagram of the pork cycle. In economics, the term pork cycle, hog cycle, or cattle cycle [1] describes the phenomenon of cyclical fluctuations of supply and prices in livestock markets. It was first observed in 1925 in pig markets in the US by Mordecai Ezekiel and in Europe in 1927 by the German scholar Arthur Hanau [ de].
Feed conversion ratio (FCR) is the ratio of inputs to outputs; it is the inverse of "feed efficiency" which is the ratio of outputs to inputs. [ 2] FCR is widely used in hog and poultry production, while FE is used more commonly with cattle. [ 2] Being a ratio the FCR is dimensionless, that is, it is not affected by the units of measurement ...
Cobweb model. The cobweb model or cobweb theory is an economic model that explains why prices may be subjected to periodic fluctuations in certain types of markets. It describes cyclical supply and demand in a market where the amount produced must be chosen before prices are observed.
Description. [edit] Millets are small-grained, annual, warm-weather cereals belonging to the grass family. They are highly tolerant of drought and other extreme weather conditions and have a similar nutrient content to other major cereals. [ 6 ] Finger millet in the field. Ripe head of proso millet.
Proso millet is a relatively low-demanding crop, and diseases are not known; consequently, it is often used in organic farming systems in Europe. In the United States, it is often used as an intercrop. Thus, proso millet can help to avoid a summer fallow, and continuous crop rotation can be achieved.
The hydrogen cycle consists of hydrogen exchanges between biotic (living) and abiotic (non-living) sources and sinks of hydrogen-containing compounds. Hydrogen (H) is the most abundant element in the universe. [1] On Earth, common H-containing inorganic molecules include water (H 2 O), hydrogen gas (H 2 ), hydrogen sulfide (H 2 S), and ammonia ...
t. e. Marine biogeochemical cycles are biogeochemical cycles that occur within marine environments, that is, in the saltwater of seas or oceans or the brackish water of coastal estuaries. These biogeochemical cycles are the pathways chemical substances and elements move through within the marine environment. In addition, substances and elements ...
