BELOWPROPOSED GRADEBD TVHHVSPECIFICATIONSSEEDBED REQUIREMENTSEstablishment of vegetation should not be attempted on sites that are unsuitable due to excessive soil compaction, inappropriate soiltexture, 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 soilshould have these criteria:·Enough fine-grained (silt and clay) material to maintain adequate moisture and nutrient supply (available water capacity of atleast .05 inches water to 1 inch of soil).·Sufficient pore space to permit root penetration.·Sufficient depth of soil to provide an adequate root zone. The depth to rock or impermeable layers such as hardpans should be12 inches or more, except on slopes steeper than 2:1 where the addition of soil is not feasible.·A favorable pH range for plant growth, usually 6.0 - 6.5.·Free from large roots, branches, stones, large clods of earth, or trash of any kind. Clods and stones may be left on slopessteeper than 3:1 if they are to be hydro seeded.If any of the above criteria are not met - i.e., if existing soil is too coarse, dense, shallow or acidic to foster vegetation - specialamendments are required. The soil conditioners described below may be beneficial or, preferably, topsoil may be applied.SEEDBED PREPARATIONInstall necessary mechanical erosion and sedimentation control practices before seeding, and complete grading according to theapproved plan.Lime and fertilizer needs should be determined by soil tests. Directions, sample cartons, and information sheets are available throughcounty Agricultural Extension offices. Testing is also done by commercial laboratories.When soil tests results are not available, follow rates suggested in the seeding specifications shown at right. Application rates usuallyfall into the following ranges:·Ground agricultural limestone: Light-textured, sandy soils: 1 to 1-1/2 tons/acreHeavy-textured, clayey soils: 2-3 tons/acre·Fertilizer: Grasses: 800-1200 lb/acre of 10-10-10 (or theequivalent) Grass-legume mixtures: 800-1200 lb/acre of 5-10-10 (or the equivalent)Apply lime and fertilizer evenly and incorporate into the top 4-6 inches of soil by disking or other suitable means. Operate machineryon the contour. When using a hydro seeder, apply lime and fertilizer to a rough, loose surface.Roughen surfaces prior to seeding.Complete seedbed preparation by breaking up large clods and raking into a smooth, uniform surface (slopes less than 3:1). Fill in orlevel depressions that can collect water. Broadcast seed into a freshly loosened seedbed that has not been sealed by rainfall.SEEDINGSeeding dates given in the seeding mixture specifications are designated as "best" or "possible". Seedings properly carried out withinthe "best" dates have a high probability of success. It is also possible to have satisfactory establishment when seeding outside thesedates. However, as you deviate from them, the probability of failure increases rapidly. Seeding on the last date shown under"possible" may reduce changes of success by 30-50%. Always take this into account in scheduling land-disturbing activities.Use certified seed for permanent seeding whenever possible.Labeling of non-certified seed is also required by law. Labels contain important information on seed purity, germination, and presenceof wood seeds. Seeds must meet State standards for content of noxious weeds. Do no accept seed containing "prohibited" noxiousweed seed.Inoculate legume seed with the Rhizobium bacteria appropriate to the species of legume.Apply seed uniformly with a cyclone seeder, drop-type spreader, drill, cultipacker seeder, or hydro seeder on a firm, friable seedbed.When using a drill or cultipacker seeder, plant small grains no more than 1 inch deep, grasses and legumes no more than 1/2 inch.Equipment should be calibrated in the field for the desired seeding rate.When using broadcast-seeding methods, subdivide the area into workable sections and determine the amount of seed needed foreach section. Apply one-half the seed while moving back and forth across the area, making a uniform pattern: then apply the secondhalf in the same way, but moving at right angles to the first pass.Mulch all plantings immediately after seeding.HYDRO SEEDINGSurface roughening is particularly important when hydro seeding, as a roughened slope will provide some natural coverage for lime,fertilizer, and seed. The surface should not be compacted or smooth. Fine seedbed preparation is not necessary for hydro seedingoperations: large clods, stones, and irregularities provide cavities in which seeds can lodge.Rate of wood fiber (cellulose) application should be at least 2,000 lb/acre.Apply legume inoculants at four times the recommended rate when adding inoculant to a hydro seeder slurry.If a machinery breakdown of 1/2 to 2 hours occurs, add 50% more seed to the tank, based on the proportion of the slurry remaining.This should compensate for damage to seed. Beyond 2 hours, a full rate of new seed may be necessary.Lime is not normally applied with a hydraulic seeder because it is abrasive. It can be blown onto steep slopes in dry form.MAINTENANCEGenerally, a stand of vegetation cannot be determined to be fully established until soil cover has been maintained for one full yearfrom 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-establishthe stand after seedbed preparation or over- seed the stand. Consider seeding temporary, annual species if the time of year is notappropriate 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 re-fertilization in the second growing season. Fine turfrequires annual maintenance fertilization. Use soil tests if possible or follow the guidelines given for the specific seeding mixture.TEMPORARY SEEDING SPECIFICATIONSSeeding mixture (fall) Species* Rate (lb/acre)Rye Grain (Secale cereale)120Seeding Mixture (late winter early spring)Species* Rate (lb/acre)Rye Grain (Secale cereale)120Seeding mixture (summer)Species* Rate (lb/acre)German Millet (Setaria italica)40Seeding dates (Piedmont)Fall:Aug. 15 - Dec. 30Late winter (early spring): Jan. 1 - May 1 LateSummer:May 1 - Aug. 15Soil amendmentsFollow recommendations of soil tests or apply 2,000 lb/acre ground agricultural limestone and 750 lb/acre 10-10-10 fertilizer.MulchApply 4,000 lb/acre straw.
