Seed Coating

Inoculants - PRE-VAIL & Nitragin Gold
Blue River alfalfas and clovers are inoculated with PRE-VAIL and Nitragin Gold.
PRE-VAIL and Nitragin Gold are approved for organic use by OMRI and OCIA.

Inoculation is the application of rhizobia bacteria to seed. The presence of rhizobia is necessary for a legume (such as alfalfa or red clover) to be able to convert atmospheric nitrogen into a usable form. Proper inoculation helps alfalfa and red clover plants produce more forage and build more nitrogen in the soil.

Apex Green Hydroloc Organic Seed Coating
Blue River is pleased to make available Apex Green Hydroloc seed coating on select varieties of alfalfa seed to help customers have more productive stands of alfalfa. Apex Green Hydroloc seed coating is a carefully formulated mix of minerals and carefully selected strains of rhizobia bacteria. Apex Green Hydroloc is specifically designed for legume seed, is virtually dust-free, and bonds to each seed in a dense durable coating. The coating provides for a protected germination zone to ensure seed to plant survivability and to stimulate vigorous growth in young seedlings.

Apex Green Hydroloc Organic Seed Coating ensures;

  • Nodulation
  • Improved seedling emergence
  • More uniform stands
  • More productive plants per pound of seed

With Apex Green coated seeds you can grow more plants per bag, even though you are actually planting less seed. Uncoated seed performs well under perfect field conditions, but Apex Green Seed Coating provides good performance under less than perfect conditions.
