Fall Rye(groin) 120
Summer German Millet 40
Seeding Dates
Fall. August 15 — December 30
Summer. • April 15 — August 15
Soil Amendments:
Fallow soil test or apply 2000 Ib/acre
ground agricultural limestone and 1000
lb/acre 10-10-10 fertilizer.
Mulch:
Apply 4000 Ib/acre straw, anchor straw by
tacking with asphalt, netting, or a mulch
anchoring tool. A disk with blades set nearly
straight can be used as a mulch anchoring tool.
Maintenance:
Fall. Repair and fertilize damaged areas immediately.
Topdress with 50 Ib/acre of nitrogen in March.
If is is necessary to extend temporary cover beyond
June 15, overseed with 50 ib/acre Kobe Lespedeza
in late February or early March.
Summer: Refertilize if growth is not fully adequate.
Reseed, Refertilize, and mulch immediately following
erosion or other damage.

Best Possible Seeding Dates
Early Spring: February 15 — April 30
Fall: September 1 — October 31
Soil Amendments:
Follow soil test or apply 3000 — 5000 ib/acre
ground agricultural limestone (use lower rate
on sandy soils) and apply 1000 Ib/acre
of 10--10-10 fertilizer.

Summer. Refertilize if growth is not fully adequate.
Reseed, Refertilize, and mulch immediately following
erosion or other damage.
Seeding Notes:
1. From September 1 — March 1 use unscarified Sericea
seed
2. On poorly drained sites omit Sericea seed and increase
Kobe to 40 Ib/acre
J. Where a neat apperonce is desired, omit sericea and
increase Kobe to 40 ib/acre.
4. Nurse plants between April 15 — August 15.
5. Add to seed mixture 10 ib/acre of German millet or 15 Iblacre
sudangrass if planted prior to May 1
6. Add to seed mixture 25 /b/acre Rye (grain) if planted after

CONSTRUCTION:
INSTALL SEDIMENT TRAP iN ACCORDANCE WITH THE NC EROSION AND SEDIMENTATION CONTROL PLANNING AND DESIGN MANUAL
MAINTENANCE:
INSPECT TEMPORARY SEM/MENT TRAPS AFTER EACH PERIOD OF SIGNIFICANT RAiLFALL. REMOVE AND RESTORE TRAP TO iTS ORIGINAL
DIMENSIONS WHEN THE SEDIMENT HAS ACCUMULATED TO ONE—HALF THE DISIGN DEPTH OF THE SPILLWAY TO ENSURE IT IS AT LEAST
1.5 FEET BELOW THE LOW POINT OF THE EMBANKMENT. IMMEDIATELY FILL ANY SETTLEMENT OF THE EMBANKMENT TO SLIGHTLY ABOVE
GRADE. ANY RIP RAP DISPLACED FROM THE SPILLWAY MUST BE REPLACED IMMEDIATELY.
AFTER ALL SEDIMENT—PRODUCING AREAS HAVE BEEN PERMANENTLY STABILIZED, REMOVE THE SEDIMENT TRAP AND ALL UNSTABLE SEDIMENT.
AND SMOOTH THE AREA TO BLEND WITH THE ADJOINING AREAS AND STABILIZE PROPERLY.
