Product Description

KingFisher SynergyX Fortress alfalfa is a blend of legumes that can fix most of its own nitrogen. KF SynergyX Fortress is a blend of alfalfa with different types of root systems.

  • Sunken Crown root helps bring great traffic tolerance
  • Branch roots keep the plant firmly in the ground during freezing and thawing
  • Creeping root and adaptable alfalfas round out the mix
  • Aphanomyces Race 2 (APH2) resistant alfalfas

Byron Seeds selects only the highest performing varieties for maximum yields throughout the life span of the stand.

The low-lignin industry alfalfas are good quality but they have a drag on yield. Our KingFisher alfalfas are not only excellent in quality, but they actually increase yield, KingFisher alfas have improved fiber digestibility on farms across the country.


KingFisher SynergyX Fortress can handle 28 day cutting schedules. One very critical aspect of alfalfa management is knowing when to take the last cutting in the fall. Alfalfa needs five weeks of growth before a killing frost (25 degrees F). In some areas, another cutting can be taken after frost when the alfalfa is dormant. 

Higher fall dormancy numbers in alfalfa indicate early spring and late fall growth. KF SynergyX Fortress rates at a 4.5, which makes for increased yield. For winter survival, the lower the winter survival number, the more winter-hardy the variety. Fortress is a 1.8 which means it features excellent winter hardiness. 

Alfalfa can be planted in the spring or late summer, but we advise late summer when possible. If spring sown, a nurse crop of grass or small grain is advisable to maximize the tonnage in the seeding year. We usually advisable seeding grass with alfalfa to increase tonnage and product a better quality feed for the life of the stand.

Good ratios of sulfur, boron, and phosphorus as well as a pH above 6.5 are critical for alfalfa. Nitrogen is key for good grass yields (older than 6 months) give off compounds that prevent new alfalfa seedlings from establishing.
