Summary and Implications
Seven treatments applied to alfalfa were compared to evaluate their effect on profitable alfalfa production. Other than meeting the lime requirement based on ISU soil test recommendations, no other treatment added profitability. Research is still limited on defining soil test and plant analysis levels to provide a reasonable probability of an economic return to Boron fertilization of alfalfa.
