Soil is composed of organic matter (decomposing plants, animals, and microbes), biomass (living plants, animals, and microbes), water, air, minerals (sand, silt, and clay), and nutrients (nitrogen, carbon, phosphorus). [4] For optimal plant growth, a proper carbon to nitrogen ratio of 20–30:1 must be maintained. [3]
Regenerative agriculture is a conservation and rehabilitation approach to food and farming systems. It focuses on topsoil regeneration, increasing biodiversity, [1] improving the water cycle, [2] enhancing ecosystem services, supporting biosequestration, [3] increasing resilience to climate change, and strengthening the health and vitality of farm soil.
Assisted natural regeneration (ANR) (also termed managed regrowth) is the human protection and preservation of natural tree seedlings in forested areas. Seedlings are, in particular, protected from undergrowth and extremely flammable plants such as Imperata grass. Though there is no formal definition or methodology, the overall goal of ANR is ...
The Society for Ecological Restoration defines restoration as "the process of assisting the recovery of an ecosystem that has been degraded, damaged, or destroyed." [1] Restoration ecology is the academic study of the science of restoration, whereas ecological restoration is the implementation by practitioners. [21]
Only the best trees are left to seed the regeneration. In many cases the mineral soil is intentionally exposed by equipment allowing small-seeded species that require exposed soil to grow. [ 2 ] [ 6 ] Sometimes, the cut is followed by the use of herbicides or prescribed fire to suppress any undesired vegetation. [ 2 ]
Such techniques are known by the collective terms agroforestry and farmer-managed natural regeneration. [2] A 2010 documentary feature film, The Man Who Stopped the Desert, first screened in the UK, portrays his life. [3] Sawadogo was a native speaker of Mossi. [2] In 2018, he was awarded the Right Livelihood Award. [4]
The new growth of seedlings and community assembly process is known as regeneration in ecology. [ 1 ] [ 2 ] As ecological succession sets in, a forest will slowly regenerate towards its former state within the succession ( climax or any intermediate stage), provided that all outer parameters (climate, soil fertility availability of nutrients ...
Soil regeneration is the reformation of degraded soil through biological, chemical, and or physical processes. [ 2 ] When productivity declined in the low-clay soils of northern Thailand, farmers initially responded by adding organic matter from termite mounds , but this was unsustainable in the long-term.
