SEEDBED REQUIREMENTS:
ESTABLISHMENT OF VEGETATION SHOULD NOT BE ATTEMPTED ON SITES THAT ARE UNSUITABLE DUE TO
INAPPROPRIATE SOIL TEXTURE (TABLE 6.10A), POOR DRAINAGE, CONCENTRATED OVERLAND FLOW, OR
STEEPNESS OF SLOPE UNTIL MEASURES HAVE BEEN TAKEN TO CORRECT THESE PROBLEMS.
TO MAINTAIN A GOOD STAND OF VEGETATION, THE SOIL MUST MEET CERTAIN MINIMUM REQUIREMENTS AS A
GROWTH MEDIUM. THE EXISTING SOIL SHOULD HAVE THESE CRITERIA:
- ENOUGH FINE-GRAINED (SILT AND CLAY) MATERIAL TO MAINTAIN ADEQUATE MOISTURE AND NUTRIENT
SUPPLY (AVAILABLE WATER CAPACITY OF AT LEAST 0.05 INCHES WATER TO 1.00 INCH OF SOIL).
- SUFFICIENT PORE SPACE TO PERMIT ROOT PENETRATION.
- SUFFCENT DEPTH OF SOIL TO PROVIDE AN ADEQUATE ROOT ZONE. THE DEPTH TO ROCK OR
IMPERMEABLE LAYERS SUCH AS HARDPANS SHOULD BE 12 INCHES OR MORE, EXCEPT ON SLOPES
STEEPER THAT 2:1 WHERE THE ADDITION OF SOIL IS NOT FEASIBLE.
- A FAVORABLE H RANGE FOR PLANT GROWTH USUALLY 6.0 - 8.5.
- FREE FROM LARGE ROOTS, BRANCHES, STONES , LARGE CLODS OF EARTH, OR TRASH OF ANY KIND.
CLODS AND STONES MAY BE LEFT ON SLOPES STEEPER THAN 3:1 IF THEY ARE HYDROSEEDED.
IF ANY OF THE ABOVE CRITERIA ARE NOT MET - I.E. IF EXISTING SOIL IS TOO COARSE, DENSE, SHALLOW,
OR ACIDIC TO FOSTER VEGETATION - SPECIAL AMENDMENTS ARE REQUIRED. THE SOIL CONDITIONERS
DESCRIBED BELOW MAY BE BENEFICIAL OR, PERFERABLY, TOPSOIL MAY BE APPLIED.
SEEDBED PREPARATION:
FILL SLOPES (PERMANENT SEEDING) - FOR FILL SLOPES 3:1 OR STEEPER:
1. LEAVE THE LAST 4-6 INCHES OF FILL LOOSE AND UNCOMPACTED, ALLOWING ROCKS, ROOTS, LARGE
CLODS AND OTHER DEBRIS TO REMAIN ON THE SLOPE.
2. ROUGHEN SLOPE FACES BY MAKING GROOVES 2-3 INCHES DEEP, PERPINDICULAR TO THE SLOPE.
3. SPREAD LIME EVENLY OVER SLOPES AT RATES RECOMMENDED BY SOIL TESTS.
FILL SLOPES (TEMPORARY SEEDING) - FOR FILL SLOPES 3:1 OR STEEPER: 1. LEAVE A LOOSE,
UNCOMPACTED SURFACE. REMOVE LARGE CLODS, ROCKS, AND DEBRIS WHICH MIGHT
HOLD NETTING ABOVE THE SURFACE.
2. SPREAD LIME AND FERTILIZER EVENLY AT RATES RECOMMENDED BY SOIL TESTS.
3. INCORPORATE AMENDMENTS BY ROUGHENING OR GROOVING SOIL SURFACE ON THE CONTOUR.
FOR HIGH -MAINTENANCE TURF:
1. REMOVE ROCKS AND DEBRIS THAT COULD INTERFERE WITH TILLAGE AND THE PRODUCTION OF A
UNIFORM SEEDBED.
2. APPLY LIME AND FERTILIZER AT RATES RECOMMENDED BY SOIL TESTS; SPREAD EVENLY AND
INCORPORATE TO A DEPTH OF 2-4" WITH A FARM DISK OR CHISEL PLOW.
3. LOOSEN THE SUBGRADE IMMEDIATELY PRIOR TO SPREADING TOPSOIL BY DISKING OR SCARIFYING TO
A DEPTH OF AT LEAST 2 INCHES.
4. SPREAD TOPSOIL TO A DEPTH OF 2-4 INCHES AND CULTIPACK.
5. DISK OR HARROW AND RAKE TO PRODUCE A UNIFORM AND WELL -PULVERIZED SURFACE.
6. LOOSEN SURFACE JUST PRIOR TO APPLYING SEED.
FOR GENTLE OR FLAT SLOPES WHERE TOPSOIL IS NOT USED:
1. REMOVE ROCKS AND DEBRIS.
2. APPLY LIME AND FERTILIZER AT RATES RECOMMENDED BY SOIL TESTS; SPREAD EVENLY AND
INCORPORATE INTO THE TOP 6" WITH DISK, CHISEL PLOW, OR ROTARY TILLER.
3. BREAK UP LARGE CLODS AND RAKE INTO A LOOSE, UNIFORM SEEDBED.
4. RAKE TO LOOSEN SURFACE JUST PRIOR TO APPLYING SEED.
NOTE:
LIME AND FERTILIZER NEEDS SHOULD BE DETERMINED BY SOIL TESTS. SOIL TESTING IS PERFORMED FREE
OF CHARGE BY THE NORTH CAROLINA DEPARTMENT OF AGRICULTURE (NCDA) SOIL TESTING LABORATORY.
DIRECTIONS, SAMPLE CARTONS, AND INFORMATION SHEETS ARE AVAILABLE THROUGH COUNTY AGRICULTURAL
EXTENSION OFFICES OR FROM NCDA. ALLOW 1-6 WEEKS FOR SAMPLE TURN -AROUND SO PLAN WELL IN
ADVANCE OF FINAL GRADING.
WHEN SOIL TEST ARE NOT AVAILABLE, FOLLOW RATES SUGGESTED ON THE INDIVIDUAL SPECIFICATION SHEET
FOR THE SEEDING MIX CHOSEN (TABLES 6.11C THROUGH 6.11V). APPLICATION RATES USUALLY FALL INTO
THE FOLLOWING RANGES:
- GROUND AGRICULTURAL LIMESTONE:
LIGHT -TEXTURED, SANDY SOILS: 1 TO 1-1/2 TONS/ACRE
HEAVY -TEXTURED, CLAYEY SOILS: 2-3 TONS/ACRE
- FERTILIZER:
GRASSES: 800-1,200 LB/ACRE OF 10-10-10 (OR THE EQUIVALENT)
GRASS -LEGUME MIXTURES: 800-1,200 LB/ACRE OF 5-10-10 (OR THE EQUIVALENT)

FOR GRASS -LINED CHANNELS
Seeding Mixture Rate (Ib/acre)
Tall Fescue 200 (4-5 lb/1,000 sq. ft.)
Nurse Plants:
Between May 1 and Aug. 15 add 15 lb/acre Sudangrass or 10 lb/acre German
Millet. Before May 1, or After Aug. 15, add 40 lb/acre rye (grain).
Seeding Dates:
Best: Aug. 25 - Oct.
Possible: Feb. - Aug.
Avoid seeding from Nov. to Jan. If seeding must be done at this time, add
40 lb/acre rye grain and use a channel lining that offers maximum protection.
Soil Amendments:
Apply lime and fertilizer according to soil tests, or apply 4,000 lb/acre
ground agricultural limestone and 1,000 lb/acre 10-10-10 fertilizer.
Operate tillage equipment across the waterway.
Mulch:
Use jute, erosion control matting, or other effective channel lining material to
cover the bottom of the channels and ditches, and staple securely. The lining
should extend above the highest calculated depth of flow. On channel side
slopes above this height, and in drainages not requiring temporary linings,
apply 4,000 lb/acre grain straw and anchor straw by stapling netting over
the top.
Mulch and anchoring material must not be allowed to wash down slopes
where they can clog drainage devices.
Maintenance:
Inspect and repair mulch frequently. Refertilize in late winter of the following
year; use soil tests or apply 150 lb/acre 10-10-10. Mow regularly to a
height of 2-4 inches.
REFERENCE: NORTH CAROLINA EROSION AND SEDIMENT CONTROL MANUAL.
FOR SLOPES 3:1 OR STEEPER
Seeding Mixture Rate (lb/acre)
Tall Fescue 200 (4-5 lb/1,000 sq. ft.)
Sericea Lespedeza 30 (0.7-0.8 lb/1,000 sq. ft.)
Kobe Lespedeza 10 (0.2-0.3 lb/1,000 sq. ft.)
Seeding Notes:
1. In Eastern Piedmont add 25lb/acre Pensacola Bahiagrass or 10 lb/acre common
Bermudagrass. Use common Bermudagrass only where it is unlikely to become a pest.
2. After Aug. 15 use unscarified sercia seed.
3. Where a neat appearance is desired, omit sercia and substitute 40 lb/acre Bahiagrass
or 15 lb/acre hulled Bermudagrass.
4. To extend spring seeding dates into June, add 15 lb/acre hulled Bermudagrass.
However, it is perferable to seed temporary cover and seed Fescue in September.
Nurse Plants:
Between May 1 and Aug. 15 add 15 lb/acre Sudangrass or 10 lb/acre German
Millet. Before May 1, or After Aug. 15, add 40 lb/acre rye (grain).
Seeding Dates:
Best: Fall (Aug. 25 - Sep. 15), Late Winter (Feb. 15 - Mar. 21)
Possible: Fall (Aug. 20 - Oct. 25), Late Winter (Feb. 1 - Apr. 15)
Fall is best for Tall Fescue and late winter for lespedezas. Overseeding of Kobe Lespedeza
over fall -seeded Tall Fescue is very effective. Use unhulled Bermudagrass seed in fall.
Soil Amendments:
Apply lime and fertilizer according to soil tests, or apply 4,000 lb/acre
ground agricultural limestone and 1,000 lb/acre 10-10-10 fertilizer.
Mulch:
Apply 4,000-5,000 lb/acre grain straw or equivalent cover or another suitable mulching
material. Anchor mulch by tacking with asphalt, roving, or netting. Netting is the pre-
ferred anchoring method on steep slopes.
Maintenance:
Inspect and repair mulch frequently. Refertilize in the second year unless
growth is fully adequate. Mow regularly to a height of 2-4 inches in
necessary areas. Other areas may be mowed once or twice a year,
but is not necessary.

SEEDING:
FOR PERMANENT SEEDING FILL SLOPES STEEEPER THAN 3:1, USE HYDRAULIC SEEDING EQUIPMENT TO APPLY
SEED AND FERTILIZER, A WOOD MULCH FIBER AT 45 LB/1,000 SQ. FT., AND MULCH TACTIFER.
FOR GENTLE TO FLAT SLOPES OR TEMPORARY SEEDING, BROADCAST SEED AT THE RECOMMENDED RATE WITH
A CYCLONE SEEDER, DROP SPREADER, OR CULTIPACK SEEDER. RAKE SEED INTO THE SOIL AND LIGHTLY
PACK TO ESTABLISH GOOD CONTACT.
USE CERTIFIED SEED FOR PERMANENT SEEDING WHENEVER POSSIBLE. CERTIFIED SEED IS INSPECTED BY THE
NORTH CAROLINA CROP IMPROVEMENT ASSOCIATION. IT MEETS PUBLISHED NORTH CAROLINA STANDARDS
AND SHOULD BEAR AN OFFICIAL "CERTIFIED SEED" LABEL.
LABELING OF NON -CERTIFIED SEED IS ALSO REQUIRED BY LAY. LABELS CONTAIN IMPORTANT INFORMATION
ON SEED PURITY, GERMINATION, AND PRESENCE OF WOOD SEEDS. SEEDS MUST MEET STATE STANDARDS
FOR CONTENT AND NOXIOUS WEEDS. DO NOT ACCEPT SEED CONTAINING "PROHIBITED" NOXIOUS WEED SEED.
FOR PERMANENT SEEDING FILL SLOPES 3:1 OR GREATER:
- IN MID -SUMMER, LATE FALL, OR WINTER, APPLY 100 LB/1000 SQ. FT. GRAIN STRAW, COVER WITH
NETTING AND STAPLE TO THE SLOPE. IN SPRING OR EARLY FALL USE 45 LB/1000 SQ. FT. WOOD
FIBER
IN A HYDROSEEDER SLURRY.
FOR HIGH -MAINTENANCE VEGETATION AND TEMPORARY SEEDING:
- APPLY 90 LB/1000 SQ. FT. (4,000 LB/ACRE) GRAIN STRAW AND TACK WITH 0.1 GAL/SQ. YD.
ASPHALT (11 GAL/1000 SQ. FT.)
FOR GRASS -LINED CHANNELS:
- INSTALL RECOMMENDED EROSION CONTROL MAT IN THE CHANNEL, EXTEND UP THE CHANNEL BANKS
TO THE HIGHEST CALCULATED DEPTH OF FLOW (SEE GRASS -LINED CHANNEL DETAIL), AND SECURE
AND ANCHOR.
MAINTENANCE:
GENERALLY, A STAND OF VEGETATION CANNOT BE DETERMINED TO BE FULLY ESTABLISHED UNTIL SOIL
COVER HAS BEEN MAINTAINED FOR ONE FULL YEAR FROM PLANTING, INSPECT SEEDED AREAS FOR FAILURE
AND MAKE NECESSARY REPAIRS AND RESEEDINGS WITHIN THE SAME SEASON, IF POSSIBLE.
RESEEDING - IF A STAND HAS INADEQUATE COVER, RE-EVALUATE CHOICE OF PLANT MATERIALS AND
QUANTITIES OF LIME AND FERTILIZER. RE-ESTABLISH THE STAND AFTER SEEDBED PREPARATION OR
OVERSEED THE STAND. CONSIDER SEEDING TEMPORARY, ANNUAL SPECIES IF THE TIME OF YEAR IS NOT
APPROPRIATE FOR PERMANENT SEEDING.
IF VEGETATION FAILS TO GROW, SOIL MUST BE TESTED TO DETERMINE IF ACIDITY OR NUTRIENT IMBALANCE
IS RESPONSIBLE.
FERTILIZATION - ON THE TYPICAL DISTURBED SITE, FULL ESTABLISHMENT USUALLY REQUIRES
REFERTILIZATION IN THE SECOND GROWING SEASON. FINE TURF REQUIRES ANNUAL MAINTENANCE
FERTILIZATION. USE SOIL TESTS IF POSSIBLE OR FOLLOW THE GUIDELINES GIVEN FOR THE SPECIFIC SEEDING
MIXTURE.
Tall Fescue 250 (4-5 lb/1,000 sq. ft.)
Nurse Plants:
Between May 1 and Aug. 15 add 35 lb/acre German Millet.
Before May 1, or After Aug. 15, add 40 lb/acre Rye (Grain).
Seeding Dates:
Best: Aug. 25 - Oct.
Possible: Feb. - Aug.
Avoid seeding from Nov. to Jan. If seeding must be done at this time, add
40 lb/acre rye grain.
Soil Amendments:
Apply lime and fertilizer according to soil tests, or apply 4,000 lb/acre
ground agricultural limestone and 1,000 lb/acre 10-10-10 fertilizer.
Mulch:
Apply 4,000-5,000 lb/acre grain straw or equivalent cover or
another suitable mulching material.
Maintenance:
Inspect and repair mulch frequently. Topdress with 10-10-10 fertilizer if
growth is not fully adequate. Mow regularly to a height of 2-4 inches.
