Nutrient Value Of Corn Stover

Some animal operations are interested in corn stover as a feed leading many crop producers to ask - what is the nutrient value of my corn stover?
From a pure fertilizer value, corn stover contains a little phosphorus (P2O5) and moderate amounts of nitrogen (N) and potassium (K2O). The actual amounts of N, P2O5, and K2O contained in a ton of corn stover are 16, 6, and 25 pounds, respectively. A 160 bushel per acre corn crop will produce 4.5 tons of stover per acre removing 72 pounds of N, 25 pounds of P2O5, and 113 pounds of K2O. Thus stover does have some fertilizer value especially with regard to potassium that may require some additional fertilizer input in subsequent years, but soil testing should be conducted to validate the need for additional nutrients.
