Winter legumes can substitute for applied nitrogen fertilization of corn. Stochastic
dominance
was used to order net revenues from legume and applied nitrogen alternatives.
Stochastic dominance orderings indicate that systems combining vetch with low applied
nitrogen fertilization (50 and 100 pounds/acre, respectively) were risk inefficient.
By contrast,
vetch and 150 pounds acre applied nitrogen maximized expected net revenue and
was risk efficient for a wide range of risk-averse and risk-seeking behavior. Farmers
with
these risk attitudes may not reduce applied nitrogen if they switch to a vetch cover.
Extremely
risk-averse or risk-seeking farmers would not prefer winter legumes.
