Davey Arbor Green® PRO
Inspired by Nature
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.

Why Fertilize?
• Forest Trees
• Recycle
•
•
nutrients
Build soil over
time
Urban Trees
•
•
•
•
Little or no
recycling
Disturbed soils &
sub-soils
Turf competition
Limited natural
nitrogen
Davey Arbor Green® PRO
• Optimal Soil Nutrients will:
• Hasten maturity of young trees
• Maintain health & vigor of trees
• Rescue declining trees
• Cure nutrient deficiencies

Key Benefits
•
•
•
Superior
performance
Use 25% less
nitrogen
Lower cost
application
Tree Growth Comparison
Trial on established trees
Length of trial – 3 years
Patented Formulation
PPA – Polyaspartate
PPA amino acid improves
nutrient availability.
• Compared to humates, PPA
has 3 to 4 times as many
nutrient holding sites per
particle.
Result:
Less fertilizer needs to be
applied.
The lower application rate addresses
environmental stewardship and lower cost.
Slow Release Nitrogen
Davey Arbor Green
PRO nitrogen
source contains
66% water
insoluble nitrogen
(WIN), which
provides uniform
slow release rate.

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.
Microbial Breakdown
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.
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.
Low Salt Index
A Low Salt Index Means Low Burn Potential
Arbor Green
PRO
is ideal to use on
sensitive, newly
planted, droughtstressed, or
trees in decline.
The AGP salt
index is 10 or
less compared
with other
products at 15 to
120.

•
Use For:
•
•
Fertilizing small caliper
trees, shrubs and potted
plants.
When planting small caliper
trees, shrubs, potted and
other landscape plants.

•
•
Tear open the packet and
disperse directly in planting
hole or directly on soil near
the plants. Water in.

•
Conventional spray equipment
Agitation
• Paddle agitation or
• Jet agitation with Venturi
nozzles
Standard soil injection probe
with 4 lateral ports on tip.
• FMSC 785 or other
standard spray gun
attached to injection
probe.
150 to 200 psi
Tank Agitation
• Spray tank should
be equipped with
sufficient agitation
to maintain fertilizer
suspension.
•
Mechanical paddle
agitation is
recommended.
Mixing Rate
One Year Rate
Mix 15 lbs. (1/2
bag) of Davey
Arbor Green
PRO in 100
gallons of water.
Mixing Procedure
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.
Re-suspend
Use soil-probe to resuspend the material.
Avoid agitation
paddles
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.
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.
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 seconds
4. Space injections
three (3) feet apart.
5. Inject to a depth of 4
to 12 inches.
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.
Application - Liquid Injection
• Liquid injection
places the fertilizer
in contact with
roots.
• Granular fertilizers
require irrigation to
move those
fertilizers to the
root zone.
Tree Application Pattern
•
•
•
3-foot centers
under tree canopy to
dripline.
Grid or circles
Avoid trunk and root
crown to minimize
mechanical damage
to trees or shrubs.
Incorrect Application
Shrub Application
Injection
•
•
•
Apply 1/10 gallon per
injection
Two (2) feet between
injections.
1 second per
injection
Shrub Application
Packets
• Disperse contents
of packet around
base of shrub or
plant according to
label instructions
• Water in.
