This is an appeal by Kimball County, Nebraska, from the order of the State Board of Equalization and. Assessment increasing the valuation of both urban and rural land and improvements as shown by the 1965 abstract of assessment for Kimball County.
In its reply brief, the county contends that the proceedings of the state board ■ were void because of its failure to comply with the provisions of the Administrative Procedures Act, sections 84-901 and 84-909 to 84-919, R. S. Supp., 1963. The objection is raised for the first time in this court. Kimball County appeared before *483the board and participated in the hearing without objecting to the notice or the procedure of the board.
In County of Blaine v. State Board of Equalization & Assessment, ante p. 471, 143 N. W. 2d 880, we held that there are practical difficulties which prevent a strict and literal application of the Administrative Procedures Act to the proceedings of the state board where the board is attempting to equalize the valuation of real estate in all 93 counties. Upon an appeal to this court from the State Board of Equalization and Assessment, the issue is whether the record of the proceedings before the board shows that the order was unreasonable and arbitrary. If the record demonstrates that the order of the board was arbitrary, it will be reversed. Fromkin v. State, 158 Neb. 377, 63 N. W. 2d 332.
The county contends that the order of the state board increasing the valuation of both urban and rural property was arbitrary and capricious. The order of the state board directed that the valuation of urban property in Kimball County, as reflected by the 1965 abstract of assessment, be increased 7 percent, and that rural property be increased 29 percent.
The testimony with respect to Kimball County shows that Kimball County was reappraised in 1957; that the county board reduced the value of rural lands 20 percent from the appraised values; that until a year ago, professional appraisers were employed to keep the appraisals up to date; that an employee of the county, who was trained by the appraisal company, now does this work; that the land around the city of Kimball was revalued 2 years ago; that the land in Cheyenne County along the county line is assessed somewhat higher than the land in Kimball County; that the land in-Kimball County along the Banner County line is assessed higher than the land in Banner County; that the difference in assessed value is due to the difference in the quality and type of land; that the sales-assessment ratio for Kimball County is 21.21 for rural and 27.01 for urban; and that *484most sales of rural property are of tracts which are purchased as additions to operating units.
The testimony does not show how the sales-assessment ratio which appears in the record was computed. The county objected to some of the sales, and it is not clear whether these sales were used in computing the ratio. Upon this state of the record, we must assume that the ratio was computed accurately and that the sales used were representative.
The evidence relating to the sales-assessment ratio indicates that some increase in the value of rural property should have been made. The increase which was made brought the sales-assessment ratio for rural property in Kimball County to 27.36, which appears to be the median for all counties as adjusted by the state board.
Much of the county’s brief is devoted to a comparison of the valuation of Cheyenne County land with that in Kimball County. The sales-assessment ratio for Cheyenne County, as shown by the record, is 31.83 for rural.
The county argues that any increase in the valuation of rural property should have been restricted to land and that m> increase should have been made in the value of improvements. The argument assumes that the state board could not do more than restore the 20 percent reduction in the value of rural land which was made at the time of the 1957 reappraisal. The justification for the 1965 increase, that may be found in the record, is the sales-assessment ratio. Equalization based upon a comparison of sales-assessment ratios must include both land and improvements since, usually, there is no way to apportion consideration between land and improvements.
The increase in the value of urban property in Kim-ball County brought the sales-assessment ratio for that property to 28.9. This appears to be slightly above the average and the median for all counties as adjusted by the. state board.
The county calls attention to the fact that 18 counties with sales-assessment ratios approximately the same or *485less than Kimball County were not changed or the valuation was reduced. Attention might also be directed to counties with sales-assessment ratios higher than Kim-ball County which were not changed or the value increased.
Although the record does not explain why the state board took this particular action, this court should not interfere with the discretion of the board when the discrepancy appears to be slight. Mathematical exactness can never be obtained, and substantial compliance with equality and uniformity is all that is required.
Upon consideration of the entire record, we are unable to say that the action of the State Board of Equalization and Assessment, so far as Kimball County is concerned, was arbitrary and capricious or prejudicial. The order is, therefore, affirmed.
Affirmed.
