Agricultural soils, having been depleted of much of their native carbon stocks, have a significant CO2 sink capacity. Global estimates of this sink capacity are in the order of 20-30 Pg C over the next 50-100 years .Management practices to build up soil C must increase the input of organic matter...

Agricultural soils as a sink to mitigate CO2 emissions
Legume—maize crop rotations are used as a mechanism to reverse declining soil fertility in West Africa. However, such crop rotations exhibit a relatively low recovery of legume N. Temperate region studies partly attribute low N recovery to gaseous N losses, but this has not been established for m...

An agricultural ecosystem is an ecosystem managed with a purpose, usually to produce crops or animal products. Agricultural ecosystems are designed by humans, and are based on a long chain of experience and experiments. The emphasis in, for example, Western Europe has changed from maximum product...
