1 Tree and Shrub Fertilizer Arbor Green ® PRO

2 Davey Arbor Green® PRO The Davey Institute has researched the natural soil conditions of the forest floor and recognizes the challenges of the urban forest soil. Arbor Green PRO mimics nutrient delivery as seen in the natural forest environment. Microbial release of nutrients Microbial release of nutrients nutrient ratio nutrient ratio Low salt index Low salt index Long term nutrient buildup Long term nutrient buildup Inspired by Nature

3 Davey Arbor Green® PRO Why Fertilize? Forest Trees Forest Trees Recycle nutrients Recycle nutrients Build soil over time Build soil over time Urban Trees Urban Trees Little or no recycling Little or no recycling Disturbed soils & sub-soils Disturbed soils & sub-soils Turf competition Turf competition Limited natural nitrogen Limited natural nitrogen

4 Davey Arbor Green® PRO Optimal Soil Nutrients will: Optimal Soil Nutrients will: Hasten maturity of young trees Hasten maturity of young trees Maintain health & vigor of trees Maintain health & vigor of trees Rescue declining trees Rescue declining trees Cure nutrient deficiencies Cure nutrient deficiencies

5 Arbor Green PRO Developed by a tree company for use by tree companies Developed by a tree company for use by tree companies Patented formulation Patented formulation Backed by Davey Backed by Davey Key Benefits Superior performance Superior performance Use 25% less nitrogen Use 25% less nitrogen Lower cost application Lower cost application Davey Arbor Green® PRO Tree Growth Comparison Trial on established trees Length of trial – 3 years UntreatedTreated

6 Patented Formulation PPA – Polyaspartate PPA amino acid improves nutrient availability. Compared to humates, PPA Compared to humates, PPA has 3 to 4 times as many has 3 to 4 times as many nutrient holding sites per nutrient holding sites per particle. particle.Result: Less fertilizer needs to be applied. The lower application rate addresses environmental stewardship and lower cost.

7 Slow Release Nitrogen Davey Arbor Green PRO nitrogen source contains 66% water insoluble nitrogen (WIN), which provides uniform slow release rate.

8 Nitrogen Release Mimics Natural Organics Slow Release Nitrogen Charts adapted from Nu-Gro.

9 Excess soluble nitrogen can over-stimulate vegetative growth possibly upsetting root to shoot balance. Succulent new cell growth may have weak cell walls leading to damage by insects. Excessive new growth can take away nutrients used by the plant to produce natural plant defenses used to protect against insects and disease. Slow Release Nitrogen Charts adapted from Nu-Gro. AGP Compared to Other Slow Release Nitrogen

10 1. Microorganisms utilize the carbon in ureaform and release the nitrogen for the plant. 2. Because this is a biological process, it slows in cool and/or dry soils. 3. The biological release rate reduces nitrogen leaching. Microbial Breakdown

11 Building the Soil Nitrogen in Davey Arbor Green PRO will remain in the soil at a significantly higher level than conventional fertilizers resulting in more uniform growth response and healthier plants. Percent of Soil Nitrogen Over 7 Years

12 Arbor Green PRO is ideal to use on sensitive, newly planted, drought- stressed, or trees in decline. The AGP salt index is 10 or less compared with other products at 15 to 120. Low Salt Index BeforeAfter A Low Salt Index Means Low Burn Poten tial

13 Arbor Green PRO Patented Formulation Use 25% less nitrogen Long lasting Two year application rate Improves nutrient holding capacity of soil compared to conventional fertilizers with humate additives Low Salt Index (less than 10) Non burning – not only for use on normal trees but also newly planted, stressed, and declining trees. Also for use on shrubs. Low Leach Potential Cost Effective

19 Tank Agitation Spray tank should Spray tank should be equipped with be equipped with sufficient agitation sufficient agitation to maintain fertilizer to maintain fertilizer suspension. suspension. Mechanical paddle agitation is recommended.

20 Mixing Rate One Year Rate Mix 15 lbs. (1/2 bag) of Davey Arbor Green PRO in 100 gallons of water.

21 Mixing Procedure Fill the tank with water and engage the pump during fill-up. Fill the tank with water and engage the pump during fill-up. Add fertilizer slowly, in 5 lb. increments, to the water to ensure proper suspension.

22 Re-suspend Use soil-probe to re- suspend the material. Use soil-probe to re- suspend the material. Avoid agitation paddles

23 Calibration With 300 ft of ¾ inch diameter hose, there is a pressure loss of approximately 5 psi per 50 ft of hose, so the pump pressure should be set at a minimum of 150 psi. With 300 ft of ¾ inch diameter hose, there is a pressure loss of approximately 5 psi per 50 ft of hose, so the pump pressure should be set at a minimum of 150 psi.

24 Calibration 1. Collect fertilizer solution 2. Record time to collect ½ gallon 3. This should be about 4 seconds. 4. Increase or decrease pressure to be near 4 sec.

25 Tree Application gal. /1,000 sq. ft 2. Under canopy 3. Apply one-half (1/2) gallon of suspension per injection. Approx. 4 seconds 4. Space injections three (3) feet apart. 5. Inject to a depth of 4 to 12 inches.

26 Application – Liquid Injection Sub-surface injection helps break-up compaction. Sub-surface injection applies fertilizer where the roots are. Start injection below the turfgrass roots to avoid competition for nutrients.

27 Liquid injection Liquid injection places the fertilizer places the fertilizer in contact with in contact with roots. roots.
