Product Description


KingFisher Stonghold alfalfa is a legume that can fix most of its own nitrogen. Stronghold features a sunken crown for excellent traffic tolerance, while branched roots keep the plant firmly in the ground during freezing and thawing and help protect the root from water damage, keeping more roots above the water table.  Byron Seeds selects only the highest-performing varieties for maximum yields throughout the life span of the stand. 

  • disease resistant to Aphanomyces Race 2
  • Sunken crown for great traffic tolerance
  • branch root helps avoid winter kill


It is recommended to do a soil test before planting. Proper nutrients are needed for highest yields. 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. Plant with a drill or Brillion seeder into a firm seedbed; 18-22 lbs./A Fall dormancy number is 4.3, which indicates early spring and late fall growth. The winter survival number is 1.8. Lower the number the more winter hardy the variety is. 


KingFisher Stonghold 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.
