LONG-TERM PROFITABILTIY OF ANIMAL MANURE USING OPTIMAL NITROGEN APPLICATION RATE

Dynamic optimization compared the NPV of manure and ammonium fertilizers on irrigated corn. Yield, soil residual nitrogen and pH functions were estimated from a six year experiment in Oklahoma. Results show that given prices of corn and nitrogen fertilizer, animal manures provide a higher NPV of return than ammonia fertilizer.
