This document provides a sample organic system plan for a Midwestern crop farm transitioning to organic production. The farm grows row crops, small grains, and alfalfa hay both organically and conventionally. The plan includes detailed farm maps, field histories, and descriptions of the farm's soil and crop management, organic integrity practices, and recordkeeping system. Supplementary documents provide additional details on notifications, land use history, soil tests, manure sources, and a biodiversity plan. The sample aims to demonstrate how a full organic system plan might be structured to meet USDA organic certification requirements.
