Spackman was raised in southern Idaho where he worked on local farms and for a fertilizer co-op. His masters and doctoral work emphasized nitrogen management for corn cropping systems in the U.S. Midwest. His research and Extension articles have covered topics of nitrogen fertilizer rate, source and timing in relation to corn uptake and use efficiency in the soil-corn system.
