Agriculturists can store more carbon in soil through techniques such as no-till farming that leaves crop residue on the ground instead of plowing it up and releasing the carbon into the atmosphere.No-till farming does away with the mechanical churning of the soil between crops.Crop residue covers soil surface conserves water and reduces erosion by 70% or more.Intact soil suffers less erosion retains more nutrients and holds water more effectively.Earthworms proliferate and create channels that foster root growth.Crop yields are similar to tillage system yields.Less tillage of soil reduces labour fuel and machinery costs for farmers.
