Managing Manure on Alfalfa Hay

Abstract

Alfalfa is a high-quality, high-yielding, cool-season forage that can be profitably marketed as hay. Manure can be an excellent source of phosphorus, potassium and boron for alfalfa production and can reduce the need for purchasing other sources of these nutrients. Research in Wisconsin and Minnesota has shown manure can sometimes improve alfalfa yields when compared with other fertilizer sources. However, there are significant challenges in managing manure on alfalfa without damaging the productivity of the stand, particularly with solid manure and manure slurries. This guide introduces factors producers should consider before applying manure on alfalfa.
