In a study conducted by the US Agricultural Research Service (ARS), an organically managed ARS pecan orchard consistently out-yielded a commercial, conventionally managed, chemically fertilized orchard over a five year period. For example, yields from the 20-acre organic test site surpassed the commercial orchard by 18 pounds (8 kg) of pecan nuts per tree in 2005, and by 12 pounds (5.4 kg) per tree in 2007. (Bradford J.M., 2008).
Furthermore, while he conventional management system generates about $1,750 per acre when the crop is sold, the ARS certified-organic-management system can gross $5,290 per acre.
