1st Choice Seeds NBank Mix

NBank Mix is a Nitrogen producer (legume) blended with a nutrient scavenger (brassica). Our NBank Mix combination not only captures and fixes Nitrogen, it can have quick nutrient release in the spring giving this cover crop a high possibility of producing a nutrient credit for your next crop. This blend is our improved Crimson Clover mixed with our proven premium radish. Crimson Clover contributes a fine, fibrous root system and usually overwinters. Clover is easy to terminate in the spring. The radish will winterkill below 20°F. NBank is best planted after wheat and is an excellent choice before corn.
