Boards of county commissioners may make contributions of money, supplies, equipment, office facilities, and other property or services, which will be of value or use to organized soil conservation districts, within or without the boundaries of such county, if said board determines that the work accomplished by such conservation districts will be of value to the general welfare and benefit of such county. Any money expended by the boards for such uses and purposes shall be drawn from the general fund in the county treasury not otherwise appropriated. Boards may anticipate the expenditure of such funds for such purposes and enter the expenditure in their annual statement to the county budget commission for its inclusion in such budget upon which rates of taxation are established and fixed in the manner provided by law.
