ADDITIONAL ASRU RESEARCH PROJECTS
The bulk of the research conducted by ASRU scientists is dictated by the Unit’s five-year research plan developed with input from producers and other stakeholders. These studies are typically four to 10 year projects designed to evaluate multi-year effects of cropping systems and management practices on productivity and sustainability.
However, occasionally smaller studies are also done in response to specific topics suggested by producers or to address questions that arise from our more complex projects.
Included on this page are write-ups of results from those more focused short-term studies that span only one to three years. For additional information on research under the ASRU five-year plan, please see the following:

ASRU SHORT-TERM RESEARCH: Descriptions and Results
- Fertigation of Sugarbeet: Application Timing (click here for PDF; 59 KB)
Bart Stevens and Bill Iversen, USDA-ARS-NPARL, Sidney, MT
This three-year study was undertaken to determine whether late nitrogen applications can increase yields while maintaining acceptable sucrose levels in well-drained, sandy soils. The study was developed to address grower concerns that N leaching in sandy soils may be contributing to N deficiencies later in the season accounting for the yield reductions commonly reported in those soil types.
- Furrow Irrigation in Strip Tilled Sugarbeet (click here for PDF; 3.2 MB)
Bill Iversen, USDA-ARS-NPARL, Sidney, MT
While the benefits of strip tillage in sugarbeets have been previously identified by ASRU researchers under linear move and pivot sprinkler systems, concern for the effect of residue on the flow of water in furrow irrigated fields has slowed adoption for those producers. To address those concerns, this study compares water flows in furrow irrigated sugarbeet fields under conventional versus strip tillage.
