Peat-based inoculant is applied directly to seed before planting. The symbiotic relationship of Rhizobium bacteria cultures colonize crop roots to help gather and fix "free" nitrogen in the air, making it more available to the plants. Treatment enables faster germination and stimulates plant hormones responsible for root formation and development, resulting in healthy plant growth and higher yields. Contains Sinorhizobium meliloti and Rhizobium leguminosarum biovar trifolii bacteria. NOTE: Must be used within one season. Expiration date is stamped on the bag. Treats 50 lb. of seed. Quantity: 6 oz.
