2. Zinc DDP for 2016 season:

3. Plan for the BIG 5 Nitrogen PotassiumPhosphorus Zinc Sulfur 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

4. 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

5. 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 potential Broadcast, Pre-plant application of Zinc DDP coated on N-P-K dry fertilizer

6. DDP Nutrients Perform Zinc trials – University of Kentucky – high pH, high phosphorus soils

7. 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

8. 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

9. Why is Timing Important? Most micronutrients DO NOT move well within the plant or soil Immobile within PLANT Boron Zinc Copper Manganese Iron Immobile within PLANT Boron Zinc Copper Manganese Iron Immobile within SOIL Zinc Copper Manganese Iron Phosphorus Immobile within SOIL Zinc Copper Manganese Iron Phosphorus

10. 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.

11. Nutrients move naturally through xylem as the plant grows Zn P P P P P P One issue with soil applied micronutrients has been “scarcity” Zn

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

13. 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

14. 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 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

15. 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

16. 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

17. 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

18. DDP Nutrients offer a better solution Better distribution with EvenCoat™ Technology + Highly effective PlantActiv™ Formulation = Earlier delivery of nutrients 153 granules of fertilizer throughout rooting depth, all coated with DDP Micronutrients mean better root interception (15x5x3 inch soil profile) 2 granules of micronutrient are sparsely distributed and leave micronutrient fertilization to chance DDP Coating of 0.9 lb/ac on 150 lb/ac 34-17 dry blend Typical granular micronutrient at 5 lb/ac

19. Comparison – Zinc DDP Versus Granular TreatmentsRate Zinc granular5 lb Elemental/ac Zinc DDP 0.90 lb/ac Untreated 0 TreatmentsRate Zinc granular5 lb Elemental/ac Zinc DDP 0.90 lb/ac Untreated 0

20. 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
