The Level A economic analysis of potentially irrigable acreage the Southern Ute and Ute Mountain Ute Indian Reservations specifies crop budgets and gives estimates of on farm returns for potentially irrigable lands in ten different climatic zones. The Level B economic analysis includes three factors that were not considered in the Level A analysis. First, land classes (soil types that may affect crop suitability are considered and changes in cropping patterns are made when indicated. Second the Level B economic analysis incorporates land preparation charges for tree, brush and grass removal that will be necessary prior to irrigated agricultural use Finally the Level B economic analysis considers economies of scale and farm efficiency factors as they apply to individual parcels or groups of parcels and makes any adjustments in cost and or returns necessary for a final potentially irrigable acreage determination.
