1 Tree and Shrub Fertilizer Arbor Green® PROTree and Shrub Fertilizer
2 Inspired by Nature Davey Arbor Green® PRO The Davey Institute has researched the natural soilconditions of the forest floor and recognizes the challenges of the urbanforest soil.Arbor Green PROmimics nutrient delivery asseen in the natural forestenvironment.Microbial release of nutrients3-1-1 nutrient ratioLow salt indexLong term nutrient buildup
3 Davey Arbor Green® PRO Why Fertilize? Forest Trees Urban Trees Recycle nutrientsBuild soil over timeUrban TreesLittle or no recyclingDisturbed soils & sub-soilsTurf competitionLimited natural nitrogenUrban Trees have had the natural nutrient recycling disrupted. In most cases nitrogen and other nutrients are being removed from urban environment with leaf and litter removal. Suboptimal conditions are the norm, not the exception.
4 Optimal Soil Nutrients will: Davey Arbor Green® PROOptimal Soil Nutrients will:Hasten maturity of young treesMaintain health & vigor of treesRescue declining treesCure nutrient deficiencies
5 Davey Arbor Green® PRO Arbor Green PRO Key Benefits Developed by a tree company for use by tree companiesPatented formulationBacked by DaveyUntreatedTreatedKey BenefitsSuperior performanceUse 25% less nitrogenLower cost applicationTree Growth ComparisonTrial on established treesLength of trial – 3 years
6 Patented Formulation PPA – Polyaspartate PPA amino acid improvesnutrient availability.Compared to humates, PPAhas 3 to 4 times as manynutrient holding sites perparticle.Result:Less fertilizer needs to be applied.The lower application rate addresses environmental stewardship and lower cost.
7 Slow Release NitrogenDavey Arbor Green PRO nitrogen source contains 66% water insoluble nitrogen (WIN), which provides uniform slow release rate.
9 Slow Release Nitrogen AGP Compared to Other Slow Release Nitrogen 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.Charts adapted from Nu-Gro.
10 Microbial Breakdown1. 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.
11 Building the Soil Percent of Soil Nitrogen Over 7 Years 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.
12 Low Salt Index A Low Salt Index Means Low Burn Potential Arbor Green PROis 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.BeforeAfter

17 Arbor Green PRO 30-10-7 Packets Use For:Fertilizing small caliper trees, shrubs and potted plants.When planting small caliper trees, shrubs, potted and other landscape plants.Easy-to-Use. No MixingTear open the packet and disperse directly in planting hole or directly on soil near the plants. Water in.Easy to Measure1 dbh inch tree: 1 packet2 dbh inch tree: 2 packets3 dbh inch tree: 3 packetsPackaging48 packets per display2 displays per carton96 packets per cartonNote: Same patented formulation as AGP in 30 lb. bag.
18 Application Basics Product Characteristics Equipment Requirements Suspendable formulationIndefinite shelf lifeNon-hazardousNon-corrosiveOdorlessPathogen freeWeight – 30 lb. bagsPallet – 40 bagsEquipment RequirementsConventional spray equipmentAgitationPaddle agitation orJet agitation with Venturi nozzlesStandard soil injection probe with 4 lateral ports on tip.FMSC 785 or other standard spray gun attached to injection probe.150 to 200 psi
19 Tank Agitation Spray tank should be equipped with sufficient agitation to maintain fertilizersuspension.Mechanical paddleagitation isrecommended.
20 Mixing RateOne Year RateMix 15 lbs. (1/2 bag) of Davey Arbor Green PRO in 100 gallons of water.
21 Mixing ProcedureFill 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-suspendUse soil-probe to re-suspend the material. Avoid agitation paddles
23 CalibrationWith 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 gallon3. This should be about 4 seconds.4. Increase or decrease pressure to be near 4 sec.
25 Tree Application 1. 50 gal. /1,000 sq. ft 2. Under canopy 3. Apply one-half (1/2) gallon of suspension per injection. Approx. 4 seconds4. 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 competitionfor nutrients.
27 Application - Liquid Injection places the fertilizerin contact withroots.Granular fertilizersrequire irrigation tomove thosefertilizers to theroot zone.
28 Tree Application Pattern 3-foot centersunder tree canopy to dripline.Grid or circlesAvoid trunk and root crown to minimize mechanical damage to trees or shrubs.Avoid trunk and root crown to minimize mechanical damage to tree/shrub
30 Shrub Application Injection Apply 1/10 gallon per injection Two (2) feet between injections.1 second per injection
31 Shrub Application Packets Disperse contents of packet around base of shrub or plant according to label instructionsWater in.
