A fertile soil has the capacity to supply the nutritional needs of the plants being established. Good soil quality characteristics include good soil texture, adequate nutrients available for plant growth, good moisture holding capacity, and the appropriate soil acidity/alkalinity balance (pH). The following is a discussion of the steps needed to ensure good vegetative growth. 1. Soil Tests Soil tests are extremely important and should be conducted on every site. Soil tests provide specific information on the amounts of phosphorus, potassium, calcium and magnesium available for plant uptake and recommends additional amounts as required. Soil tests are crucial for determining the amount of lime needed to obtain an appropriate soil pH for the vegetation being established. Soil test results include recommendations specific to the site and vegetation being grown. Soil tests recommend the amount of plant nutrients and lime needed to promote and maintain good plant growth. Soil tests may be performed by the Cooperative Extension Service Soil Testing Laboratory at VPI & SU, or by a reputable commercial laboratory. Also note that County Extension offices have soil testing supplies and information. Soil tests are not used to determine nitrogen needs. Nitrogen is applied based upon established requirements for the plant to be grown, season of growth, and intended use. 2. Surface Roughening Provide a rough soil surface by stair -step grading, grooving, or tracking the soil to be vegetated or by leaving slopes in a roughened condition by not fine -grading, in accordance with the 1992 Virginia Erosion & Sediment Control Handbook (Std & Spec 3.29). Seed germination is difficult with compacted soils. Rough, loose soil surfaces helps prevent the loss of lime and fertilizer due to runoff, increases water infiltration, and provides seed coverage, which aids in seed germination. 3. Soil Amendments & Soil Quality Materials such as sand, vermiculite, peat, and compost may be added to soil to modify texture, improve structure and increase the moisture holding capacity. It is also recommended to conserve existing soil quality by preserving and reapplying topsoil in accordance with the 1992 Virginia Erosion & Sediment Control Handbook (Std & Spec 3.30). Areas that have been compacted, or where duff or underlying topsoil is removed, should be amended with compost to improve soil quality. 4. Lime Adjusting the soil pH between 6.25 to 6.5 is extremely important for grass establishment, especially in the acidic soils of Virginia. A soil test is necessary to determine the actual amount of lime required to adjust the soil pH of denuded sites. However, when a soil test has not been performed, apply 2-tons/acre (90 pounds per 1,000 square feet) of pulverized agricultural grade limestone. Revised 7/17/03 Page 2 of 8 Erosion & Sediment Control Technical Bulletin No. 4 Nutrient Management for Development Sites 5. Fertilizer Never aDDly more than 1 Dound of water soluble nitrogen Der 1.000 sauare feet within a 30 day ep riod. Nitrogen should be applied based upon established requirements of the plant to be grown, season of growth, and intended use. Establishing a uniform dense vegetative cover with a good root system reduces the potential for pollution by decreasing erosion and runoff, increasing the plants ability for nutrient uptake, and reducing pesticide use. A detailed discussion on fertilizer use is provided in the `Updated Fertilizer Specifications and Rates for Establishment' section of this bulletin. 6. Incorporation Incorporate the lime and fertilizer into the top 4 - 6 inches of the soil by discing or by other means. Incorporation reduces the potential nutrient loss due to runoff, as well as significantly increasing the success of establishing a vegetative cover. When surface roughening does not occur prior to the application of lime and fertilizer, `mix' the lime and fertilizer into the soil, at least 4 inches, by the methods described in the 1992 Virginia Erosion and Sediment Control Handbook (Std & Spec 3.29). When incorporation does not occur, and fertilizer and lime is applied directly to a smooth surface, the phosphorus (P205) application rate must be reduced by half because of the limited contact area with soil and the risk of nutrients being lost in runoff. 7. Seeding Selection of plants is based on climate topography,soils land use and the planting season. The P � P g 1992 Virginia Erosion and Sediment Control Handbook vegetative cover standards and specifications 3.31 Temporary Seeding, 3.32 Permanent Seeding, 3.33 Sodding, and 3.34 P P mil' g� g> g� Bermudagrass & Zoysiagrass, describe in detail the specifications for plant selection. In addition, attached are one -page updates to the vegetative cover standards and specifications, which provide updated fertilizer and lime rates and the seeding schedules for the different P P g physiographic regions of Virginia. 8. Mulching The application of mulch to the soil surface, for both temporary and permanent seeding, is one of the most effective means of controlling runoff and erosion on disturbed land. All permanent seeding must be mulched immediately upon completion of seed application. It is especially important to mulch liberally in mid -summer and prior to winter. Mulching prevents erosion, and thereby pollution, by protecting the soil surface and fostering the growth of vegetation by increasing the moisture content and providing insulation from extreme temperatures. The 1992 Virginia Erosion and Sediment Control Handbook (Std & Spec 3.35) details the mulch specifications and includes a list of the typical materials used to mulch (for example straw, wood chips, and fiber mulch). Revised 7/17/03 Page 3 of 8 Erosion & Sediment Control Technical Bulletin No. 4 Nutrient Management for Development Sites 9. Hydroseeding H droseedin is a mechanical method of applying seed fertilizer, and mulch to land Y g > development sites in one step. This method is efficient in providing an immediate cover to denuded sites; however, the surface must be carefully prepared in order for successful seed germination. Hydroseed on rough, loose surfaces only. Roughen the surface prior to application of hydroseeding, per the specification above and in accordance with the 1992 Virginia Erosion & Sediment Control Handbook (Std & Spec 3.29). Although proper soil pH is crucial in establishing good vegetative cover, lime is usually not included in the hydroseed mix. Therefore, lime should be incorporated into the soil as needed when preparing the site for hydroseeding. To avoid poor seed germination as a result of seed damage during hydroseeding, it is recommended that if the machinery breaks down from 30 minutes to 2 hours, 50% more seed must be added to the tank. Beyond 2 hours, a full rate of new seed is usually necessary. UPDATED FERTILIZER SPECIFICATIONS AND RATES FOR ESTABLISHMENT Plant nutrients should be applied based upon established requirements of the plant to be grown, season of growth, and intended use, as specified in the 1992 Virginia Erosion and Sediment Control Handbook (Std & Spec 3.31, 3.32, 3.33, and 3.34). The timing and rate of fertilizer application depends on the type of grass. There are basically two types of grasses, warm and cool season grasses. Warm season grasses (Bermuda, Zoysia) are those that go dormant in the winter. Cool season grasses (Fescue, Bluegrass) are those that stay green year round. 1. Recommended Season for Applying Nitrogen Fertilizers The earliest spring application of nitrogen for cool season grasses is six weeks prior to the last average frost date (for example, February 6 for Virginia Beach and March 1 for Roanoke). The latest fall application of nitrogen for cool season grasses is six weeks after the first average frost date (for example, December 29 for Virginia Beach and December 1 for Roanoke). The earliest spring application of nitrogen for warm season grasses is the last average frost date for the region (for example, March 20 for Virginia Beach and April 15 for Roanoke). The latest fall application of nitrogen for warm season grasses is 30 days prior to the average first frost date for the region (for example, October 15 for Virginia Beach and September 20 for Roanoke). 2. Per Application Rates Phosphorus (P) and potassium (K) fertilizer requirements should be determined by a soil test. Never apply more than one (1) pound of water soluble nitrogen per 1,000 square feet within a 30 day period. The following table itemizes the fertilization rate revisions to standards and specifications 3.31 Temporary Seeding, 3.32 Permanent Seeding, 3.33 Sodding, and 3.34 Bermudagrass & Zoysiagrass Establishment.

NOTE: For cool 3.33 Sodding season grasses apply fertilizer in fall or spring. For warm season grasses apply the fertilizer in late spring or summer only. 10-10-10 fertilizer applied at a rate of 500 lbs. / acre or 12 lbs. / 1,000 ft2. Apply additional 3.34 Bermudagrass & Zoysiagrass Establishment phosphorus and potassium 30-60 days later based on the soil test. Apply an additional equivalent of 1 Ib./1,000 Prof nitrogen when the P & K are applied. 3. Using Fertilizer Analysis to Calculate Nitrogen Rates All fertilizer packages have three numbers present on the package (for example, 10-10-10 or 16- 4-8). These three numbers indicate the percentage of nitrogen (N), phosphorus (P205), and potash (K20) present by weight which is called the N-P-K ratio. For example, a 20 pound bag of 10-6-4 is 10 percent nitrogen (2 lb. of N), 6 percent phosphate (1.2 lb. of P205), and 4 percent potash (0.8 lb. of K20) the remaining is inert material to facilitate even application of fertilizer. The Virginia nutrient management recommendation is to apply no more than 1 lb. of nitrogen per 1,000 square feet within a 30 day period. A fertilization rate of 1 lb. of nitrogen per 1,000 square feet can be obtained for any site by using the fertilizer analyses on the bag and knowing the area of application. Revised 7/17/03 Page 5 of 8 Erosion & Sediment Control Technical Bulletin No. 4 Nutrient Management for Development Sites Fertilizer Bag Reads: Amount to Fertilizer to Apply 1 lb. of nitrogen / 1000 sq.ft. 6-2-0 16.6 lb. 10-10-10 10 lb. 16-4-8 6.2 lb. 20-5-5 5 lb. 22-3-14 4.5 lb. 29-3-7 3.4 lb. 4. Use of Slowly Available Forms of Nitrogen Fertilizer bags will state the source or category from which the nitrogen is derived. Nitrogen fertilizers have two categories: Water Soluble Nitro en i.e. all nitrogen is immediate) g g ( � g Y available); and Slowly Available Nitrogen (i.e., nitrogen is available over an extended period of time). The nitrogen source impacts how grass is fertilized and the rate and timing of application of fertilizer. Choose a fertilizer that has some amount of Slowly Available Slowly Available Nitrogen (SAN). Slowly available nitrogen fertilizers make nitrogen available a little at a time, the way most grasses need it, which reduces both the potential of excess nutrients in runoff and the leaching potential of excess nutrients into groundwater. Sources of SAN are usually stated on the label. It may be stated as % Water Insoluble Nitrogen (WIN), sulfur -coated urea, natural organic nitrogen or other controlled release materials used to coat the fertilizer. The % WIN is usually stated on the fertilizer container, if the % WIN is not listed, assume that all the nitrogen in the fertilizer is water soluble and immediately available. As a general guideline, if the fertilizer has 50% WIN or less, it should be applied in the same manner as readily available nitrogen. If the fertilizer is 50% WIN or greater, it should be applied as a SAN. UPDATED FERTILIZER SPECIFICATIONS AND RATES FOR MANAGEMENT 1. Application of Fertilizer for Maintenance Apply fertilizer when grass is actively growing and can utilize the nutrients. Summer is best for warm season grasses (zoysiagrass and bermudagrass) while the fall months are best for cool season grasses (tall fescue, Kentucky bluegrass, perennial ryegrass). 2. Annual Application Rates A. When applying 100% Water Soluble Nitrogen sources (those that have all the nitrogen immediately available for plant use), the following rates apply: . Never anDly more than one (1) nound of water soluble nitrogen Der 1.000 sauare feet within a 30 day period • No more than 3.5 lbs. of nitrogen per 1,000 square feet annually on cool season grass. • No more than 4.0 lbs. of nitrogen per 1,000 square feet annually on warm season grass. Erosion & Sediment Control Technical Bulletin No. 4 Nutrient Management for Development Sites B. When applying slowly available nitrogen (SAN, WIN, sulfur -coated urea, natural organic nitrogen or other controlled release materials), total annual nitrogen application rates may be adjusted incrementally by referring to the following figure. The maximum annual nirogen rates when using 50% or greater SAN is as follows: • No more than 5.0 lbs. of nitrogen per 1,000 square feet annually on cool season grass. • No more than 5.5 lbs. of nitrogen per 1,000 square feet annually on warm season grass.

Purposes 1. To prevent erosion by protecting the soil surface from raindrop impact and reducing the velocity of overland flow. 2. To foster the growth of vegetation by increasing available moisture and providing insulation against extreme heat and cold. Conditions Where Practice Applies 1. Areas which have been permanently seeded (see Std. & Spec. 3.32, PERMANENT SEEDING) should be mulched immediately following seeding. 2. Areas which cannot be seeded because of the season should be mulched to provide some protection to the soil surface. An organic mulch should be used, and the area then seeded as soon weather or seasonal conditions permit. It is not recommended that fiber mulch be used alone for this practice; at normal application rates it just simply does not provide the protection that is achieved using other types of mulch. 3. Mulch may be used together with plantings of trees, shrubs, or certain ground covers which do not provide adequate soil stabilization by themselves. 4. Mulch shall be used in conjunction with temporary seeding operations as specified in TEMPORARY SEEDING, Std. & Spec. 3.31. Planning Considerati Mulches are applied to the soil surface to conserve a desirable soil property or to promote plant growth. A surface mulch is one of the most effective means of coat*olling runoff and erosion on disturbed land. Mulches can increase the infiltration rate of the soil, reduce soil moisture loss by evaporation, prevent crusting and sealing of the soil surface, modify soil temperatures, and provide a suitable microclimate for seed germination. Organic mulch materials, such as straw, wood chips, bark, and fiber mulch have been found to be the most effective. Chemical soil stabilizers or soil binders should not be used alone for mulch. These materials are useful to bind organic mulches together to prevent displacement. A variety of manufactured SOIL STABILIZATION BLANKETS AND MATTING (see Std. & Spec. 3.36) have been developed for erosion control in recent years. Some of these products can be used as mulches, particularly in critical areas such as waterways. They also may be used to hold other mulches to the soil surface. The choice of materials for mulching will be based on the type of soil to be protected, site conditions, season and economics. It is especially important to mulch liberally in mid- summer and prior to winter, and on cut slopes and southern slope exposures. Organic Mulches Straw - The mulch most commonly used in conjunction with seeding. The straw should come from wheat or oats (free of troublesome weed seeds) and may be spread by hand or machine. Straw can be windblown and must be anchored down by an acceptable method. �I y - May be used in lieu of straw where volunteers will not present a problem, and may be spread by hand or machine. Hay can be windblown and must also be anchored or tacked down. Com Stalks - These should be shredded into 4- to 6-inch lengths. Stalks decompose slowly and are resistant to displacement. Wood Chips - Suitable for areas that will not be closely mowed, and around ornamental plantings. Chips decompose slowly and do not require tacking. They must be treated with 12 pounds of nitrogen per ton to prevent nutrient deficiency in plants; however, can be a very inexpensive mulch if chips are obtained from trees cleared on the site. Bark Chips. Shredded Bazk - These are by-products of timber processing which are used in landscaped plantings. Bark is also a suitable mulch for areas planted to grasses and not closely mowed. It may be applied by hand or mechanically and is not usually toxic to grasses or legumes; additional nitrogen fertilizer is not required. Fiber Mulch - Used in hydroseeding operations and applied as part of the slurry. It creates the best seed -soil contact when applied over top of (as a separate operation) newly seeded areas. These fibers do not require tacking, although tacking agents or binders are sometimes used in conjunction with the application of fiber mulch. This form of mulch does = provide sufficient protection to highly erodible soils. Additionally. fiber mulch will not be considered adequate mulch when used during the dry summer months or when used for late fall mulch cover. Use straw mulch during these periods. Fiber mulch may be used to tack (anchor) straw mulch. This treatment is well suited for steep slopes, critical areas, and areas susceptible to displacement. There are other organic materials which make excellent mulches but are only available locally or seasonally. Creative use of these materials can reduce .costs. Chemical Mulches and Soil Binders A wide range of synthetic, spray -on materials are marketed to stabilize and protect the soil surface. These are emulsions or dispersions of vinyl compounds, rubber or other substances which are mixed with water and applied to the soil. They may be used alone in some cases as temporary stabilizers, or in conjunction with fiber mulches or straw. When used alone, chemical mulches do not have the capability to insulate the soil or retain soil moisture that organic mulches have. This soil protection is also easily damaged by traffic. Application of these mulches is usually more expensive than organic mulching, and the mulches decompose in 60-90 days. Blankets and Matting Field experience has shown that plastic netting, when used alone, does not retain soil moisture or modify soil temperature. In some cases it may stabilize the soil surface while grasses are being established, but is primarily used in grassed waterways and on slopes to hold straw or similar mulch in place. Jute mesh and other soil stabilization blankets are good choices for mulching on difficult slopes and in minor drainage swales. Most of the soil stabilization mattings (used to create a permanent matrix for root growth within the soil) must receive mulching in order to properly stabilize an area. Notably, some manufacturers have recently developed permanent mattings which include self-contained, temporary mulching materials; however, these measures will have to meet the requirements noted in Sid. & Spec. 3.36, SOIL STABILIZATION BLANKETS AND MATTING, before they can be recommended for use on steep slopes and in channel flow situations. The most critical aspect of installing blankets and mats is obtaining firm, continuous contact between the material and the soil. Without such contact, the material may fail and thereby allow erosion to occur. It is important to use an adequate number of staples and make sure the material is installed properly in order to maximize soil protection. These products are discussed in more detail in Std. & Spec. 3.36, SOIL. STABILIZATION BLANKETS & MATTING. Specifications Organic Mulches Organic mulches may be used in any area where mulch is required, subject to the restrictions noted in Table 3.35-A. Materials: Select mulch material based on site requirements, availability of materials, and availability of labor and equipment. Table 3.35-A lists the most commonly used organic mulches. Other materials, such as peanut hulls and cotton burs, may be used with the permission of the local Plan -Approving Authority. Prior to mulching: Complete the required grading and install needed sediment control practices. Lame and fertilizer should be incorporated and surface roughening accomplished as needed. Seed should be applied .prior to mulching except in the following cases: a. Where seed is to be applied as part of a hydroseeder slurry containing fiber mulch. b. Where seed is to be applied following a straw mulch spread during winter months. TABLE 3.35-A ORGANIC MULCH MATERIALS AND APPLICATION RATES RATES: MULCHES: NOTES: Per Acre Per 1000 sq. ft.

Application: Mulch materials shall be spread uniformly, by hand or machine. When spreading straw mulch by hand, divide the area to be mulched into approximately 1,000 sq. ft. sections and place 70-90lbs. (1� to 2 bales) of straw in each section to facilitate uniform distribution. Mulch Anchoring: Straw mulch must be anchored immediately after spreading to prevent displacement. Other organic mulches listed in Table 3.35-A do not require anchoring. The following methods of anchoring straw may be used: 1. Mulch anchoring tool (often referred to as a Krimper or Krimper Tools This is a tractor -drawn implement designed to punch mulch into the soil surface. This method provides good erosion control with straw. It is limited to use on slopes no steeper than 3:1, where equipment can operate safely. Machinery shall be operated on the contour. 2. Fiber Mulch: A very common practice with widespread use today. Apply fiber mulch by means of a hydroseeder at a rate of 500-750 lbs./acre over top of straw mulch or hay. It has an added benefit of providing additional mulch to the newly seeded area. 3. Liquid mulch binders: Application of liquid mulch binders and tackifiers should be heaviest at edges of areas and at crests of ridges and banks, to prevent displacement. The remainder of the area should have binder applied uniformly. Binders may be applied after mulch is spread or may be sprayed into the mulch as it is being blown onto the soil. AplLhcation: Mulch materials shall be spread uniformly, by hand or machine. When spreading straw mulch by hand, divide the area to be mulched into approximately 1,000 sq. ft. sections and place 70-90 lbs.

Liquid mulch binders: Application of liquid mulch binders and tackifiers should be heaviest at edges of areas and at crests of ridges and banks, to prevent displacement. The remainder of the area should have binder applied uniformly. Binders may be applied after mulch is spread or may be sprayed into the mulch as it is being blown onto the soil. The following types of binders may be used: a. Synthetic binders - Formulated binders or organically formulated products may be used as recommended by the manufacturer to anchor mulch. * b. A Rho - Any type of asphalt thin enough to be blown from spray equipment is satisfactory. Recommended for use are rapid curing (RC-70, RC-250, RC-800), medium curing (MC-250, MC-800) and emulsified asphalt (SS-1, CSS-1, CMS-2, MS-2, RS-1, RS-2, CRS-1, and CRS-2). Apply asphalt at 0.10 gallon per square yard (10 gal./1000 sq. ft. or 430 gal./acre). Do not use heavier applications as it may cause the straw to "perch" over rills. All asphalt designations are from the Asphalt Institute Specifications. * Note: This particular method is not used as commonly today as it once was in the past.
