RhizoSpear is a blend of Micronutrients, Sugars, Amino Acids, Defender, and Environoc 401. This blend is a great food source for the soil microbes as well as the growing corn crop. RhizoSpear can be added to any liquid fertilizer. This is our premier program to incorporate as much technology as we can for in-furrow applications. Rhizospear can be preblended with any of our liquid fertilizers for improved stands and early plant vigor.
