The sequestration potentials estimated here will be placed in the context of these three reduction amounts. Land conversion refers to land set-asides such as practiced by the Conservation Reserve Program. Under this practice, cultivated land is retired or removed from production and often seeded with perennial vegetation. Land restoration refers to practices that actively restore eroded or degraded land. Improved management refers to improved tillage, water managment and cropping practices.
Extensive rangeland is considered to have little potential.
