What is Permanent Cover? Why is it Important for Carbon Sequestration?
Permanent cover is land that is used for hay production either using alfalfa, grass, or an mixture of the two. Most of the hay that is produced is used for beef cattle or dairy production. The amount of crop inputs used in hay production is unknown, generally alfalfa is applied in the year of establishment and may be applied in subsequent years along with potash or sulphur. The amount of nitrogen fertilizer applied to grass hay land over the life of the stand is unknown. Extensive hay production is generally the norm using low levels of crop inputs.
