Hay and Forage Grower
Ash content in harvested forages can have a significant role in animal performance. Effectively, think of ash as minerals, components such as calcium, phosphorus, potassium, and magnesium. We normally regard these as essential and beneficial to both plant and livestock health, and that’s true for about the 8 percent of internal ash content in alfalfa and the 6 percent inherent in grass.
