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.
Natural topsoil is mined and conditioned for human use and makes up the bulk of commercial topsoil available. The current rate of use and erosion outpaces soil generation. [4] It is possible to create artificial topsoil which supports some of the engineering or biological uses of topsoil. [4]
Agricultural soil science studies the chemical, physical, biological, and mineralogical composition of soils as they relate to agriculture. Agricultural soil scientists develop methods that will improve the use of soil and increase the production of food and fiber crops. Emphasis continues to grow on the importance of soil sustainability.
It can also be used to grow algae for food or for biofuels. CEA methods can increase food safety by removing sources of contamination, and increases the security of supply as it is unaffected by outside environment conditions and eliminates seasonality to create a stable market pricing, which is good for both farmers and consumers.
Regenerative agriculture uses traditional farming practices developed by Native Americans, such as avoiding or reducing soil tillage, using livestock, diversifying crops, and planting cover crops ...
Soil is used in agriculture, where it serves as the anchor and primary nutrient base for plants. The types of soil and available moisture determine the species of plants that can be cultivated. Agricultural soil science was the primeval domain of soil knowledge, long time before the advent of pedology in the 19th century.
Soil fertility refers to the ability of soil to sustain agricultural plant growth, i.e. to provide plant habitat and result in sustained and consistent yields of high quality. [3] It also refers to the soil's ability to supply plant/crop nutrients in the right quantities and qualities over a sustained period of time.
In agriculture, "humus" sometimes also is used to describe mature or natural compost extracted from a woodland or other spontaneous source for use as a soil conditioner. [3] It is also used to describe a topsoil horizon that contains organic matter (humus type, [4] humus form, [5] or humus profile [6]).
