Summary: Grazing is shown to be superior to haying for organic C and N sequestration. Sequestration rates of 1.51 Mg C ha−1 yr−1 and 0.126 Mg N ha−1 yr−1 were measured during managed grazing of tall fescue over a period of 8 years on land in the southeastern United States that had previously been degraded via haying.
