Through their own efforts and with technical assistance and cost- sharing available to them, the owners and operators have installed adequate conservation treatment and manage- ment on 109.8 million acres, or 40 percent of the private agricultural lands in the basin. An additional 38 percent, or 102.8 million acres of management-type practices, and 22 percent, or 61 million acres of mechanical or vegetative-type practices, are needed to provide adequate levels of conservation treatment and management. About 84 percent, or 6.7 million acres of the eight million acres that are privately owned non-agricultural lands, are used within their capability and adequately treated for erosion control. About half of the remainder need management-type conservation practices and the balance need vegetative or mechanical practices in addition to management practices. On federally owned lands, 68 percent, or 29.3 million acres are currently adequately treated and managed. The The Conservation Program On the Great Plains Has Been Underway Since the 1930's 50 remammg 13.7 million acres in the subbasin need improved conservation treatment and management for sustained use without deterioration. The evaluation of the production capability of the basin requires a consideration of feasible land use changes. Of the 103.8 million acres of land presently used for crop production, about 4.6 million acres should be converted to a less intense use such as grassland in order to reduce the erosion hazard. Conversel~. of the 152.6 million acres of range and pasture under private ownership, about 20.2 million acres are classed as arable and exist in tracts large enough for conversion to cropland if the need should develop. Forest and wood- land and other agricultural lands were not considered in this analysis, although some conversion of forest lands and reclamation of abandoned farmsteads will un- c10llhtedly take place. There are approximately 15.3 million acres of agricultural land in the basin subject to excess water problems. This total is exclusive of the 705.7 thousand acres of land with an excess water problem caused by irrigation water that is included in irrigation systems improvements. Currently, 4.6 million acres of cropland have been provided with adequate drainage. About 37 percent of this area is currently cultivated and current use would be improved by allowing timely operations and cleaner tillage of croplands. Improved farming operations that reduce weedy growth on farm croplands may depreciate their value for upland game. An additional 2.6 million acres of pasture and range and 605 thousand acres of forest and woodland are subject to problems of excess water and are suitable for conversion to cultivated uses. About 2 million acres require project- type measures to remove the excess water from agricultural lands. The balance can be treated by individual land owners and operators. About 5.3 million acres, or 35 percent of the land with excess water problems, are considered infeasible to
