Part 649

Part 649 sets forth the process for creating and identifying the Land Resource Regions (LRR), Major Land Resource Areas (MLRA), and the Land Resource Units (LRU). This part is being updated to clearly establish the symbol convention and naming convention for MLRAs and LRUs and will become the framework for the FY16 revision of the Agriculture Handbook 296.
