Per-acre cost of cover-crop mixture clarified in research study
February 28, 2014
A recent news release from UNL Extension in the Panhandle described research into the practice of planting cover crops into wheat fields in the High Plains, especially water use and effect on wheat yields. The study compared fallow fields, single cover crops and cover-crop mixtures.
In response to questions raised about the reported per-acre cost of the cover crop mixture, the researchers have provided a clarification:
The cost of the cover crop mixture used in the study was incorrectly quoted at $60.29 per acre. This accurately reflects the costs for this particular research project, but the per-acre cost for producers would be similar to some other single-species legume cover crop plantings at about $35 per acre. The per-acre cost was higher for the research project because of the increased mixing cost for the small amount of seed used in the project.
The study was conducted at the UNL High Plains Ag Lab (HPAL) near Sidney and at a USDA research station near Akron, Colo. Results were reported recently to the HPAL Advisory Board.
Study results regarding cover crop water use and effects on subsequent wheat yields are unchanged. F
