ID study will examine manure’s impact on crops

November 5, 2012 – The Idaho Barley Commission has made a sizable funding commitment toward an eight-year study that should provide the first long-term analysis of how manure affects crops commonly used in southern Idaho rotations.

IBC will award University of Idaho Extension soils specialist Amber Moore $16,000 for each year of the project, which should cost about $90,000 per year to complete.
