New HPAL Office and Lab Dedicated

High Plains Ag Lab Ribbon Cutting

The new office and laboratory building at the University of Nebraska High Plains Ag Lab near Sidney was dedicated during the June 19 field day. Construction of the 2,800-square-foot building was supported by $500,000 raised by a local building project committee and the University of Nebraska Foundation. The more than 50 donors who contributed were recognized. Chief Industries was the general contractor. Cutting the ribbon on the new facility are (from left): Charles Hibberd, Dean and Director of Extension for UNL; Barry Shull, Facilities Director for the UNL Institute of Agriculture and Natural Resources (IANR); Charles Fenster, professor emeritus who conducted dryland cropping research for decades at HPAL; Barb Schlothauer, retired director of development for the University of Nebraska Foundation in the Panhandle; Keith Rexroth of Sidney, chair of the building committee; Gary Hergert, interim director of the UNL Panhandle Research and Extension Center for the past year; Tom Nightingale, Farm Director at HPAL; Josh Egley, Director of Development at IANR for the University of Nebraska Foundation; and Jack Whittier, newly appointed UNL Director of Research and Extension for the Panhandle.

Our mission: The High Plains Ag Lab (HPAL) is a satellite unit of the Panhandle Research and Extension Center in Scottsbluff. Our mission is to improve the profitability of dryland crop and livestock production through applied research responsive to the needs of local producers.

Crop Research:

Crop rotation systems: Research crops are produced on 27 fields ranging in size from 22 to 36 acres. View a 2009 map of research plots. Seven different crop rotations range in length from two to six years. Various cropping system components are represented: summer fallow, no-fallow, minimum tillage and no-tillage. These systems allow research with the same crops and rotations used by our clientele. In 2006, 75 acres were certified for organic production.

Irrigated plots: A 15-acre, lateral-move irrigation system enables scientists to simulate different precipitation patterns.

Long-Term Tillage Plots: Established in 1970 to compare moldboard plow, sub-tillage, and no-tillage fallow systems on winter wheat and soil parameters. A native sod treatment has been maintained.

Grain dryer and storage: A continuous flow dryer and grain storage system allow direct harvest of proso millet and emerging alternative crops with a stripper header.

Livestock Research

Nine pastures: Cattle graze crested wheatgrass pastures to assess supplementation, feed additives or health measurements on performance.
