Alfred M. Blackmer, Professor; Peter Kyveryga, Graduate Student, Agronomy,
Iowa State University. It has long been known that the quantity of nitrogen
a soil can supply for plant growth is influenced by amounts of organic carbon
added as plant residues or animal manure. However, the effects of this carbon
are overlooked in current guidelines for nutrient management planning. Discussion
will focus on the problems caused by this oversight and how they can be avoided.
