Gain an understanding of the importance of zinc for 2016 by watching this quick webinar.

1. Zinc DDP for 2016 season:

2. Plan for the BIG 5
Nitrogen
Potassium Phosphorus
ZincSulfur
Over the last ten years
many Corn Farmers
have expanded their
complete crop fertility
program to include:
• Sulfur
• Zinc
In addition to the very
important nutrients:
N-P-K
TIMING has become
IMPORTANT

3. VALUE
Early soil application of Zinc DDP
• Proper root development
Mitigates risk of planting early into
cooler soils, which limits zinc
availability
Enables the seedling to withstand
lower air temperatures
VALUE
Mid_season-Grain Fill
• It is necessary for
proper crop
maturation AND
starch formation

4. Importance of Early Delivery of Zinc
• ZINC - Better Root
Development can
have Significant
Benefits
• Better water utilization
• Better utilization of other
applied N-P-K-S
fertilizers
• Higher yield potentialBroadcast, Pre-plant
application of Zinc DDP
coated on N-P-K dry
fertilizer

6. What’s Causing Zinc Deficiency?
Larger, healthier roots can extract more nutrients from soils
• University of Illinois: Hybrids with insecticide traits removed
up to 27% more zinc per bushel

7. Is Zinc Extra or Essential?
• Zinc DDP can be a low cost input
• Having sufficient zinc allows crop to maximize
macronutrients applied
– Early season zinc can enhance root growth, that makes
water and fertilizer utilization increase
– Cutting back may save $5-15/ac . . . at what cost?
– Higher input efficiency, better overall ROI

8. Why is Timing Important?
Most micronutrients DO NOT move well within the plant or soil

9. No zinc to new growth
1.) Foliar applications can be
beneficial to address low
nutrient levels
2.) Foliar applications can be
the most expensive
application of
nutrient/elemental unit
Value: Early, Soil-apply Zinc
2/3 of the volume of a foliar
zinc application at the five-
or six-leaf (V5 or V6) stage
will hit the ground and not
correct tissue levels. . . so
you may need to make
multiple applications.

10. Nutrients move naturally through xylem as the
plant grows

One issue with soil
applied micronutrients
has been
“scarcity”
Zn

11. Zinc Utilization
The zinc needed for grain fill
can only come from the soil . . .
Very little Zinc mobility within
the plant

12. Value: Apply Zinc Before Needed
• Delivery needs to occur BEFORE needed for biological
processes
• Fixing deficiencies or “just-in-time” applications WILL rob
yield…don’t wait until foliar applications to address micros
• The micronutrient is needed WEEKS before deficiency
symptoms
• Most often a “Hidden Hunger” is not deficient

13. Know your Soil
Consider adding micronutrients to your soil analysis
Think about ZINC (even with high soil zinc levels) when:
1. Soils contain High to Very High phosphorus levels
2. High soil pH – above 6.9
3. Consistently use insecticide trait corn hybrids
Other situations:
• Low organic matter soils
• Sandy soils

14. Use Proven Technology
• Wolf Trax Zinc DDP (62%) has been field-proven in
performance for 10+ years
• More than 20 million acres of Wolf Trax DDP
Nutrients applied
• Unique technologies ensure early plant availability
and uptake

15. EvenCoat™ Technology
• Patented Coating Technology
• Each and every fertilizer granule
is coated with Wolf Trax
DDP Nutrient
• Provides more feeding sites for
plants and closer proximity to
roots
• Blanket-like distribution in the
field and better uptake by the
plant
• Allows for tailored blends
Wolf Trax utilizes N,P,K as the
delivery system

16. PlantActiv™ Formulation
DDP Nutrients have been designed for optimum plant availability
• Chemical Formulation
• DUAL ACTION™ Availability
• Resists soil tie-up
• Physical Formulation
• Ideal particle size for
plant uptake
DDP = “Dry Dispersible Powder” Technology

17. DDP Nutrients offer a better solution

19. Considerations for 2016
Zinc DDP
• Wolf Trax DDP Nutrients can be added to existing
fertilizer application, so economical for grower
• Guaranteed to fix a deficiency
• Designed for better, quicker plant uptake than granular
zinc products = better use of fertilizer dollars
