2101-0602 T-901-1 Revised 72/27/2006

901-2.2 LIME. Lime shall be ground limestone containing not less than 85% of total
carbonates, and shall be ground to such fineness that 90% will pass through
a No. 20 mesh sieve and 50% will pass through a No. 100 mesh sieve.
Coarser material will be acceptable, providing the rates of application are
increased to provide not less than the minimum quantities and depth specified
in the special provisions on the basis of the two sieve requirements above.
Dolomitic lime or a high magnesium lime shall contain at least 10% of
magnesium oxide. Lime shall be applied at the rate of 4,000 pounds per
acre. All liming materials shall conform to the requirements of ASTM C 602.
901-2.3 FERTILIZER. Fertilizer shall be standard commercial fertilizers supplied
separately or in mixtures containing the percentages of total nitrogen,
available phosphoric acid, and water-soluble potash. They shall be applied at
the rate and to the depth specified herein, and shall meet the requirements of
Fed. Spec. A-A-1909 and applicable state laws. They shall be furnished in
standard containers with name, weight, and guaranteed analysis of contents
clearly marked thereon. No cyanamide compounds or hydrated lime shall be

compacting, and establishing turf, and shall be approved by the ENGINEER
before being placed.
2101-0602 T-901-2 Revised 12/21/2006

CONSTRUCTION METHODS
901-3.1 ADVANCE PREPARATION AND CLEANUP. After grading of areas has
been completed and before applying fertilizer and ground limestone, areas to
be seeded shall be raked or otherwise cleared of stones larger than 2 inches
(50 mm) in any diameter, sticks, stumps, and other debris that might interfere
with sowing of seed, growth of grasses, or subsequent maintenance of
grass-covered areas. If any damage by erosion or other causes has occurred
after the completion of grading and before beginning the application of
fertilizer and ground limestone, the Contractor shall repair such damage. This
may include filling gullies, smoothing irregularities, and repairing other
incidental damage.
An area to be seeded shall be considered a satisfactory seedbed without
additional treatment if it has recently been thoroughly loosened and worked to
a depth of not less than 5 inches (125 mm) as a result of grading operations
and, if immediately prior to seeding, the top 3 inches (75 mm) of soil is loose,
friable, reasonably free from large clods, rocks, large roots, or other
undesirable matter, and if shaped to the required grade.
However, when the area to be seeded is sparsely sodded, weedy, barren and
unworked, or packed and hard, any grass and weeds shall first be cut or
otherwise satisfactorily disposed of, and the soil then scarified or otherwise
loosened to a depth not less than 5 inches (125 mm). Clods shall be broken
and the top 3 inches (75 mm) of soil shall be worked into a satisfactory
seedbed by discing, or by use of cultipackers, rollers, drags, harrows, or other
appropriate means.
901-3.2 DRY APPLICATION METHOD.
a. Liming. Lime shall be applied separately and prior to the application of
any fertilizer or seed and only on seedbeds that have previously been
prepared as described above. The lime shall then be worked into the top 3
inches (75 mm) of soil after which the seedbed shall again be properly graded
and dressed to a smooth finish.
b. Fertilizing. Following advance preparations and cleanup fertilizer shall
be uniformly spread at the rate that will provide not less than the minimum
quantity stated in paragraph 901-2.3.
c. Seeding. Grass seed shall be sown at the rate specified in paragraph
901-2.1 immediately after fertilizing, and the fertilizer and seed shall be raked
within the depth range stated in the special provisions. Seeds of legumes,
either alone or in mixtures, shall be inoculated before mixing or sowing, in
accordance with the instructions of the manufacturer of the inoculant. When
seeding is required at other than the seasons shown on the plans or in the
2101-0602 T-901-3 Revised 12/21/2006

special provisions, a cover crop shall be sown by the same methods required
for grass and legume seeding.
d. Rolling. After the seed has been properly covered, the seedbed shall
be immediately compacted by means of an approved lawnroller, weighing 40
to 65 pounds per foot (60 to 97 kg per meter) of width for clay soil (or any soil
having a tendency to pack), and weighing 150 to 200 pounds per foot (223 to
298 kg per meter) of width for sandy or light soils.
901-3.3 WET APPLICATION METHOD.
a. General. The Contractor may elect to apply seed and fertilizer (and
lime, if required) by spraying them on the previously prepared seedbed in the
form of an aqueous mixture and by using the methods and equipment
described herein. The rates of application shall be as specified in the special
provisions.
b. Spraying Equipment. The spraying equipment shall have a container
or water tank equipped with a liquid level gauge calibrated to read in
increments not larger than 50 gallons (190 liters) over the entire range of the
tank capacity, mounted so as to be visible to the nozzle operator. The
container or tank shall also be equipped with a mechanical power-driven
agitator capable of keeping all the solids in the mixture in complete
suspension at all times until used.
The unit shall also be equipped with a pressure pump capable of delivering
100 gallons (380 liters) per minute at a pressure of 100 pounds per square
inch (690 kPa). The pump shalt be mounted in a line that will recirculate the
mixture through the tank whenever it is not being sprayed from the nozzle. All
pump passages and pipe lines shall be capable of providing clearance for 5/8
inch (15 mm) solids. The power unit for the pump and agitator shall have
controls mounted so as to be accessible to the nozzle operator. There shall
be an indicating pressure gauge connected and mounted immediately at the
back of the nozzle.
The nozzle pipe shall be mounted on an elevated supporting stand in such a
manner that it can be rotated through 360 degrees horizontally and inclined
vertically from at least 20 degrees below to at least 60 degrees above the
horizontal. There shall be aquick-acting, three-way control valve connecting
the recirculating line to the nozzle pipe and mounted so that the nozzle
operator can control and regulate the amount of flow of mixture delivered to
the nozzle. At least three different types of nozzles shall be supplied so that
mixtures may be properly sprayed over distance varying from 20 to 100 feet
(6 to 30 m). One shall be a close-range ribbon nozzle, one amedium-range
ribbon nozzle, and one along-range jet nozzle. For case of removal and
2101-0602 T-901-4 Revised ~ 2/21/2006

cleaning, all nozzles shall be connected to the nozzle pipe by means of
quick-release couplings.
In order to reach areas inaccessible to the regular equipment, an extension
hose at least 50 feet (15 m) in length shall be provided to which the nozzles
may be connected.
c. Mixtures. Lime, if required, shall be applied separately, in the quantity
specified, prior to the fertilizing and seeding operations. Not more than 220
pounds (100 kg) of lime shall be added to and mixed with each 100 gallons
(380 liters) of water. Seed and fertilizer shall be mixed together in the relative
proportions specified, but not more than a total of 220 pounds (100 kg) of
these combined solids shall be added to and mixed with each 100 gallons
(380 liters) of water.
All water used shall be obtained from fresh water sources and shall be free
from injurious chemicals and other toxic substances harmful to plant life.
Brackish water shall not be used at any time. The Contractor shall identify to
the ENGINEER all sources of water at least 2 weeks prior to use. The
ENGINEER may take samples of the water at the source or from the tank at
any time and have a laboratory test the samples for chemical and saline
content. The Contractor shall not use any water from any source that is
disapproved by the ENGINEER following such. tests.
All mixtures shall be constantly agitated from the time they are mixed until
they are finally applied to the seedbed. All such mixtures shall be used within
2 hours from the time they were mixed or they shall be wasted and disposed
of at locations acceptable to the ENGINEER.
d. Spraying. Lime, if required, shall be sprayed only upon previously
prepared seedbeds. After the applied lime mixture has dried, the lime shall
be worked into the top 3 inches (8 cm), after which the seedbed shall again
be properly graded and dressed to a smooth finish.
Mixtures of seed and fertilizer shall only be sprayed upon previously prepared
seedbeds on which the lime, if required, shall already have been worked in.
The mixtures shall be applied by means of ahigh-pressure spray that shall
always be directed upward into the air so that the mixtures will fall to the
ground like rain in a uniform spray. Nozzles or sprays shall never be directed
toward the ground in such a manner as might produce erosion or runoff.
Particular care shall be exercised to insure that the application is made
uniformly and at the prescribed rate and to guard against misses and
overlapped areas. Proper predetermined quantities of the mixture in
accordance with specifications shall be used to cover specified sections of
known area. Checks on the rate and uniformity of application may be made
2101-0602 T-901-5 Revised 12/21/2006

by observing the degree of wetting of the ground or by distributing test sheets
of paper or pans over the area at intervals and observing the quantity of
material deposited thereon.
On surfaces that are to be mulched as indicated by the plans or designated
by the ENGINEER, seed and fertilizer applied by the spray method need not
be raked into the soil or rolled. However, on surfaces on which mulch is not
to be used, the raking and rolling operations will be required after the soil has
dried.
901-3.4 MAINTENANCE OF SEEDED AREAS. The Contractor shall protect seeded
areas against traffic or other use by warning signs or barricades, as approved
by the ENGINEER. Surfaces gullied or otherwise damaged following seeding
shall be repaired by regrading and reseeding as directed. The Contractor
shall mow, water as directed, and otherwise maintain seeded areas in a
satisfactory condition until final inspection and acceptance of the work.
When either the dry or wet application method outlined above is used for work
done out of season, it will be required that the Contractor establish a good
stand of grass of uniform color and density to the satisfaction of the
ENGINEER. A grass stand shall be considered adequate when bare spots
are one square foot or less, randomly dispersed, and do not exceed 3% of the
area seeded. If at the time when the contract has been otherwise completed
it is not possible to make an adequate determination of the color, density, and
uniformity of such stand of grass, payment for the unaccepted portions of the
areas seeded out of season will be withheld until such time as these
requirements have been met.
METHOD OF MEASUREMENT
901-4.1 The quantity of seeding to be paid for shall be the number of acres]
measured on the ground surface, completed and accepted.
BASIS OF PAYMENT
901-5.1 Payment shall be made at the contract unit price per acre or fraction thereof,
which price and payment shall be full compensation for furnishing and placing
all material and for all labor, equipment, tools, and incidentals necessary to
complete the work prescribed in this item.
