The use of soil to reduce carbon dioxide (CO2) in the atmosphere
Rattan Lal:
- Claims that 13% of CO2 in the atmosphere could be absorbed by agricultural soils
- Erosion is more likely in soil that is 1
- Lai found soil in Africa that was very 2
- It was suggested that carbon from soil was entering the atmosphere
Soil and carbon:
- plants turn CO2 from the air into carbon-based substances such as 3
- some CO2 moves from the 4 of plants to microbes in the soil
- carbon was lost from the soil when agriculture was invented
Regenerative agriculture:
- uses established practices to make sure soil remains fertile and 5
- e.g. through year-round planting and increasing the 6 of plants that are grown
California study:
- taking place on a big 7 farm
- uses compost made from waste from agriculture and 8
Australia study:
- aims to increase soil carbon by using 9 that are always green
Future developments may include:
- reducing the amount of fertilizer used in farming
- giving farmers 10 for carbon storage, as well as their produce
