the agronomy of FOLIAR FEEDING corn and soybeans

Essential Nutrients managed efficiently by foliar feeding on corn, soybean and other row crops Zn MnB

Corn

• tasseling and silking

• Dependant on Soil Moisture

• Cell wall strength, cell division, seed development

• Pollen tube growth

• sucrose and starch formation

• auxin metabolism• pollen formation• increases P uptake

stimulating early root growth.

• membrane integrity• High sensitivity to

Zinc deficiency

B Zn

• Aids in chlorophyll production.

• Synthesis of phenols (Plants natural defense)

• Biosynthesis of Lignin (Hardy roots)

• GLYPHOSTAE TOLERANT GENE

Mn

Soybean

• Pollination, pod set, seed content

• Dependant on Soil Moisture

• Cell wall strength, cell division, seed development

• Aid in nodule formation

• sucrose and starch formation

• auxin metabolism• pollen formation• membrane integrity

Brandt Research Farm 2006

Data on Manniplex technology on Soybeans (Willfarm-Agrillaince) 1996-2002

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.

• Nutrition Plus for beans.

• Soils had good fertility and adequate pH.

• No cyst nematodes.• Tipton, IN.
