then hydraulically sprayed on the soil surface the
hy,lror•rulching shall form a blotter like groundcover
impregnates] ,rniformly with seed and fertilizer and shall
allow the absorption of moisture and rain fall to
percolate to the underlying soil. hydro -mulch
specifications may be superceded by the horticultural
soils test.
B. $RPD MIXES: Seed nixes to be used on this project are
designAted on the plans and noted in the plant legend.
C GUARANTEE: The Landscape Contractor shall be
responsible for the quality of all labor and materials
as provided by subcontractors and suppliers, including
seed mix, hydroslurry ingredients and their application.
D. PRESOAKING SEEDS Seed noted to be pre-soaked shall be
done so in clean potable water for twelve (12)
Consecrative hours prior to hydroseeding. After soaking
is started, seed that drys out will be deemed
unacceptable.
F. PRTPARATION:
I. All hydroslrerry mixes shall be mixed at the site
,ender the nbservat ion of the Owner and Landscape
Architect as it is placed in the hydroslurry tank.
2. Begin slurry preparation by adding water to the tank
when the engine is at one-half throttle. When the
waiter level has reached the height of the agitator
shaft and good recirculation has been established,
add the fertilizer to the mixture (the tank shall be
at least 1/3 filled with water at this tine).
3. Open the engine throttle to full speed when the tank
is 1/2 filled with water. Add all organic
amendments, fiber, seedmix and chemicals by the time
the tank is 2/3 to 3/4 full.
4. Start spraying immediately when the tank is full and
the slurry is mixed.
F. APPLICATIONS
1. Apply the hydromulching in the form of a slurry
consisting of organic soil amendments, commercial
fertilizer, and other chemicals called for. When
hydraulically sprayed orfto the soil, the mulch shall
form a blotter like material. Direct the spray
operation so that the slurry spray will also
penetrate the soil surface as to drill and mix the
slurry components into the soil, thus enuring
maximum irnpregnation an -i coverage. The impregnation
and mixing of components will help in retaining
moisture while stabilizing soil surface from
surficial erosion.
2. Spray the area with a uniform visible coat using the
c:ark color of cellulose fiber or organic amendment
as a visible quire. The slurry shall be applied in
a downward drilling motion via a fan stream nozzle.
G. TIME LIMITS All hydroslurry mixture that has not

of off-site at the Contractor's expense.
M. CLEAN-UPs Any slurry sprayed or spilled in an area
other than that designated in the plans shall be cleaned
up at the Contractor's expense.
I. RESEEDIP01 All bare spots shall be reseeded by the
Contractor within ten (lN) days. The Contractor will be
responsible for all reseed areas for as long after
seeding as necessary until an acceptable stand of
hydroseeAed material is realized and approved by the
Owner.
