Soil Science and Regenerative Agriculture

[Soil - Quanta]

- Soil Science

Soil science is the study of soils as a natural resource on the Earth's surface, including soil formation, classification, and mapping; the physical, chemical, biological, and fertility properties of soils; and these properties as they relate to the use and management of soils.

Soil scientists express concern about how to protect soil and cropland in a world of growing populations, potential future water crises, rising per capita food consumption and land degradation.


- Regenerative Agriculture

Regenerative agriculture is a method of protecting and restoring food and agricultural systems. It focuses on topsoil regeneration, increasing biodiversity, improving the water cycle, enhancing ecosystem services, supporting biological sequestration, improving resilience to climate change, and enhancing the health and vitality of farm soils. 

Regenerative agriculture is not a specific practice in itself. Instead, proponents of regenerative agriculture use a combination of sustainable farming techniques. Practices include recycling as much farm waste as possible and adding compost material from off-farm. Regenerative agriculture for small farms and gardens is often based on concepts such as permaculture, agroecology, agroforestry, restoration ecology, critical design and holistic management. Large farms tend to be less philosophically driven and often use "no-till" and/or "reduced-till" practices. 

As soil health improves, input requirements may decrease, while crop yields may increase, as soils are more resistant to extreme weather and have fewer pests and pathogens. 

Most climate change mitigation plans focus on "reducing greenhouse gas emissions". Regenerative agriculture, the capture of carbon dioxide from the atmosphere by growing plants that transfer carbon dioxide into the soil, is almost the only technology currently available to absorb greenhouse gases already in the atmosphere, primarily through farming and cultivating forests and permanent perennial pastures and grassland.
