Learning about the local cash market and the futures market is crucial to understanding and using the grain basis. Grain basis affects farm profitability and it is important to have a solid grasp of tools, markets and historical numbers when making grain marketing decisions. Maryland farmers sell their cash grain locally to a few principal users. Most grain in the Delmarva region is produced to feed broilers on the Eastern Shore. Other grain is exported from Norfolk, Virginia. Farmers’ grain in Western Maryland supports the cattle industry in the Shenandoah Valley and feed mills in Pennsylvania.
