SOIL STABILIZATION GUIDELINES
SEEDBED PREPARATION
1. CHISEL COMPACTED AREAS AND SPREAD TOPSOIL THREE INCHES DEEP OVER ADVERSE SOIL
CONDITIONS IF AVAILABLE
2. RIP THE ENTIRE AREA TO SIX INCHES DEEP.
J. REMOVE ALL LOOSE ROCK, ROOTS AND OTHER OBSTRUCTIONS LEAVING SURFACE
REASONABLY SMOOTH AND UNIFORM
4. APPLY AGRICULTURAL LIME, FEI IILIZERR AND SUPER-HPHOSPHATE UNIFORMLY AND MIX WITH
SOIL (SEE MIXTURE BELOW.
5 CONTINUE DLLAGE UNTIL A WELL -PULVERIZED, FIRM, REASONABLY UNIFORM SEEDBED IS
PREPARED FOUR TO SIX INCHES DEEP.
6 SEED ON A FRESHLY PREPARED SEEDBED AND COVER SEED LIGHTLY WITH SEEDING
EQUIPMENT OR CULTI-PACK AFTER SEEDING.
7. MULCH IMMEDIATELY AFTER SEEDING AND ANCHOR MULCH.
IL INSPECT ALL SEEDED AREAS AND MAKE NECESSARY REPAIRS OR RESEEDINGS WITHIN THE
PLANTING SEASON, IF POSSIBLE IF STAND SHOULD BE MORE THAN 60% DAMAGED,
RE-ESTABLISH FOLLOWING THE ORIGINAL LIME, FERTILIZER AND SEEDING RATES
9. CONSULT S&EC ENVIRONMENTAL ENGINEERS ON MAINTENANCE TREATMENT AND
FERTILIZATION AFTER PERMANENT COVER IS ESTABLISHED
1O CONSULT S&EC ENVIRONMENTAL ENGINEERS FOR ADDITIONAL INFORMATION CONCERNING
OTHER ALTERNATIVES FOR WG ETA71ON OF DENUDED AREAS THE BELWO WGETA71ON RATES
ARE THOSE THAT DO WELL UNDER LOCAL CONDIDONSy OTHER SEEDING RATE COMBINATIONS
ARE POSSIBLE.

SPRIGGING PLANT SPRIGS IN FURROWS WITH A TRACIOR-DRAWN TRANSPLANTOR, OR
BROADCAST BY HAND. FURROWS SHOULD BE 4-6 INCHES DEEP AND 2 FEET APART.
PLACE SPRIGS ABOUT 2 FEET APART IN THE ROW WITH ONE END AT OR ABOVE GROUND
LEVEL. BROADCAST AT RATES SHOWN ABOVE; AND PRESS SPRIGS INTO THE TOP
ONE-HALF TO 2 INCHES OF SOIL WITH A DISK SET STRAIGHT SO THAT SPRIGS ARE NOT
BROUGHT BACK TOWARD SURFACE DO NOT MULL. FERTILIZE VERY SPARINGLY WITH
20 LBS/ACRE NITROGEN IN SPRING WITH NO PHOSPHORUS SODDING IS ANOTHER
OPTION.
TEMPORARY SEEDING
1. COMPLETE GRADING BEFORE PREPARING SEEMS AND INSTALL ALL NECESSARY
EROSION CONTROL PRACII= SUCH AS DIKES, WATERWAYS AND BASINS
2 MINIMIZE STEEP SLOPES BECAUSE THEY MAKE SEEDBED PREPARATION DIFFICULT
AND INCREASE THE EROSION HAZARD.
,L IF SOILS BECOME COMPACTED DURING GRADING LOOSEN THEM TO A DEPTH OF
6-8 INCHES USING A RIPPER, HARROW, OR CHISEL PLOW. SEEDBED PREPARATION
GOOD SEEDBED PREPARATION IS ESSENTIAL TO SUCGESnL PLANT
ESTABLISHMENT. A GOOD SEEDBED IS WELL -PULVERIZED, LOOSE AND UNIFORM.
WHERE HYDROSEEDING METHODS ARE USED, THE SURFACE MAY BE LEFT WITH A
MORE IRREGULAR SURFACE OF LARGE CLODS AND STOVES
4. LIMING - APPLY LIME ACCORDING TO SOIL TEST RECOMMENDATIONS IF THE PH
(ACIDITY) OF THE SOL IS NOT KNOW, AN APPLICATION OF GROUND
AGRICULTURAL LIMESTONE AT THE RATE OF 1 TO 1 1/2 TONS/ACRE ON
COARSE -TEXTURED SOILS AND 2-3 TONS/ACRES ON FINE -TEXTURED SOILS IS
USUALLY SUFFICIENT. APPLY UMESTONE UNIFORMLY AND INCORPORATE INTO THE
TOP 4-6 INCHES OF SOIL SOILS WITH A PH OF 6 OR HIGHER NEED NOT BE
LIMED.
S FERTIUZER- BASE APPUCA71ON RATES ON SOIL TESTS WHEN THESE ARE NOT
POSSIBLE, APPLY A 10-10-10 GRADE FERTILIZER AT 700-4000 La/ACRE BOTH
FERTILIZER AND LIME SHOULD BE INCORPORATED INTO THE TOP 4-6 INCHES OF
SOIL IF A HYDRAULIC SEEDER IS USED, DO NOT MIX SEED AND FERTILIZER MORE
THAN 30 MINUTES BEFORE APPLIC4710V.
6. SURFACE ROUGHENING- IF RECENT TILLAGE OPERATIONS HAVE RESULTED IN A
LOOSE SURFACE ADDITIONAL ROUGHENING MAY NOT BE REQUIRED EXCEPT TO
BREAK UP LARGE CLODS IF RAINFALL CAUSES THE SURFACE TO BECOME SEALED
OR CRUSTED, LOOSEN IT JUST PRIOR TO SEEDING BY DISIONG RAKING, HARROWING
OR OTHER SUITABLE METHODS GROOVE OR FURROW SLOPES STEEPER THAN .11
ON THE CONTOUR BDIORE SEEDING (PRACTICE 6.04 SURFACE ROUGHENING).
Z SEED: RYE (GRAIN) AUG 15 - MAY 1
GERMAN MILLET MAY 1 - AUG 15
8. SEEDING - EVENLY APPLY SEED USING A CYCLONE SEEDER (B ROADCASI), DRILL.
CUUIPACKER SEEDER, OR HYDROSEEDER USE SEEDING RATES GIVEN IN TABLE
6.10A-6.10I BROADCAST SEEDING AND HYROSEEDING ARE APPROPRIATE FOR
STEEP SLOPES WHERE EQUIPMENT CANNOT BE DRIVEN. HAND BROADCASTING IS
NOT RECOMMENDED BECAUSE OF THE DIFFICULTY IN ACHIEVING A UNIFORM
DISTRIBUTION. SMALL GRAINS SHOULD BE PLANTED NO MORE THAN 1 INCH DEEP,
AND GRASSES AND LEGUMES NO MORE THAN 1/2 INCH. BROADCAST SEED MUST
BE COVERED BY RAKING OR CHAIN DRAGGING AND THEN LIGHTLY FIRMED WITH A
ROLLER OR CULTIPACKER. HYDROSEEDED MIXTURES SHOULD INCLUDE A WfI
FIBER (CELLULOSE) MULCH.
9. MULCHING - THE USE OF APPROPRIATE MULCH WILL HELP ENSURE ESTABLISHMENT
UNDER NORMAL CONDITIONS AND IS ESSENTIAL TO SEEDING SUCH UNDER
HARSH SITE CONDITION (PRACTICE 6.14, MULCHING HARSH SITE CONDITIONS
INCLUDE: SEEDING IN FALL FOR WINTER COVER (WOOD FIBER MULCHES ARE NOT
CONSIDERED ADEQUATE FOR THIS USE), SLOPES STEEPER THAN 3:1,
EXCESSIVELY HOT OR DRY WEATHER; ADVERSE SOILS (SHALLOW, ROCKY, OR (HIGH
IN CLAY OR SAND), AND AREAS RECEIVING CONCENTRATED FLOW. IF THE AREA
TD BE MULCHED IS SUBJECT TO CONCENTRATED WATERFLOW, AS IN CHANNELS,
ANCHOR MULCH WITH NETTING (PRACTICE 6.14, MULCHING).
