Data on Manniplex technology on Soybeans (Willfarm-Agrillaince) 1996-2002<br />The product applied to this field (Crop Booster) is a combination micronutrient and growth hormone to help prevent deficiencies and to provide better retention of blossoms and pods. Most of the work to date by Midwest universities has focused on manganese. This product contains manganese as well as zinc, molybdenum, and boron in manitol based complex.<br />
