Excerpt from An Economic Analysis of Level Bench Systems for Forage Production in North Dakota
The use of level benches can more than double alfalfa production, increase brome grass yield by almost 75 percent, and increase wheat yields by 5 or 6 bushels per acre over the yields produced on natural slopes. The increased yields are largely the result of the benches' ability to hold snow and snowmelt water. Benches, though similar to terraces, are much wider, level overall, and diked at the ends and front.
Not enough benches are in actual farm use to provide cost and return data. Limited tests and experience elsewhere show that cost of bench construction is mainly affected by width of bench and complexity of slope. The cost per acre for construction may range from $25 for the narrowest benches on the gen tlest slopes to $353 for 70-foot benches on lo-percent slopes.
Operating costs would be higher on a level bench system than on a natural slope, because each bench and its contributing area (an unter raced area above the bench), if there was one, would be treated as a single field for harvest ing and other operations. However, data on the increase in costs are fragmentary and some of the values were estimated.

Paperback. Condizione: New. Print on Demand. This book presents the findings of collaborative research on the economic and engineering aspects of using level benches for forage production in the Northern Great Plains. The authors analyze the potential profitability of level benches, comparing them to conventional farming methods, which are typically employed for land with similar soil and topography. The book provides detailed estimates of the costs and returns of different bench widths on several slopes. It also presents extensive experimental data on water storage, yield, and soil characteristics. Utilizing this data, the authors formulated a hypothetical budget for a 100-acre field to illustrate the potential profitability and associated costs of a properly managed level bench system for alfalfa production. Thoroughly researched and clearly presented, this book contributes valuable insights into the potential of level benches as an efficient and sustainable land management technique, offering practical information to farmers and ranchers in the Northern Great Plains region and beyond.
